Here are the instructions to build _scrcpy_ (client and server).
You may want to build only the client: the server binary, which will be pushed
to the Android device, does not depend on your system and architecture. In that
case, use the [prebuilt server] (so you will not need Java or the Android SDK).
## Simple
If you just want to install the latest release from `master`, follow this
simplified process.
First, you need to install the required packages:
```bash
# for Debian/Ubuntu
sudo apt install ffmpeg libsdl2-2.0-0 adb wget \
gcc git pkg-config meson ninja-build libsdl2-dev \
libavcodec-dev libavdevice-dev libavformat-dev libavutil-dev \
libusb-1.0-0 libusb-dev
```
Then clone the repo and execute the installation script
([source](install_release.sh)):
```bash
git clone https://github.com/Genymobile/scrcpy
cd scrcpy
./install_release.sh
```
When a new release is out, update the repo and reinstall:
```bash
git pull
./install_release.sh
```
To uninstall:
```bash
sudo ninja -Cbuild-auto uninstall
```

# Domande Frequenti (FAQ)
Questi sono i problemi più comuni riportati e i loro stati.
## Problemi di `adb`
`scrcpy` esegue comandi `adb` per inizializzare la connessione con il dispositivo. Se `adb` fallisce, scrcpy non funzionerà.
In questo caso sarà stampato questo errore:
> ERROR: "adb push" returned with value 1
Questo solitamente non è un bug di _scrcpy_, ma un problema del tuo ambiente.
Per trovare la causa, esegui:
```bash
adb devices
```
### `adb` not found (`adb` non trovato)
È necessario che `adb` sia accessibile dal tuo `PATH`.
In Windows, la cartella corrente è nel tuo `PATH` e `adb.exe` è incluso nella release, perciò dovrebbe già essere pronto all'uso.
### Device unauthorized (Dispositivo non autorizzato)
Controlla [stackoverflow][device-unauthorized] (in inglese).
[device-unauthorized]: https://stackoverflow.com/questions/23081263/adb-android-device-unauthorized
### Device not detected (Dispositivo non rilevato)
> adb: error: failed to get feature set: no devices/emulators found
Controlla di aver abilitato correttamente il [debug con adb][enable-adb] (link in inglese).
Se il tuo dispositivo non è rilevato, potresti avere bisogno dei [driver][drivers] (link in inglese) (in Windows).
[enable-adb]: https://developer.android.com/studio/command-line/adb.html#Enabling
[drivers]: https://developer.android.com/studio/run/oem-usb.html
### Più dispositivi connessi
Se più dispositivi sono connessi, riscontrerai questo errore:
> adb: error: failed to get feature set: more than one device/emulator
l'identificatore del tuo dispositivo deve essere fornito:
```bash
scrcpy -s 01234567890abcdef
```
Notare che se il tuo dispositivo è connesso mediante TCP/IP, riscontrerai questo messaggio:
> adb: error: more than one device/emulator
> ERROR: "adb reverse" returned with value 1
> WARN: 'adb reverse' failed, fallback to 'adb forward'
Questo è un problema atteso (a causa di un bug di una vecchia versione di Android, vedi [#5] (link in inglese)), ma in quel caso scrcpy ripiega su un metodo differente, il quale dovrebbe funzionare.
[#5]: https://github.com/Genymobile/scrcpy/issues/5
### Conflitti tra versioni di adb
> adb server version (41) doesn't match this client (39); killing...
L'errore compare quando usi più versioni di `adb` simultaneamente. Devi trovare il programma che sta utilizzando una versione differente di `adb` e utilizzare la stessa versione dappertutto.
Puoi sovrascrivere i binari di `adb` nell'altro programma, oppure chiedere a _scrcpy_ di usare un binario specifico di `adb`, impostando la variabile d'ambiente `ADB`:
```bash
set ADB=/path/to/your/adb
scrcpy
```
### Device disconnected (Dispositivo disconnesso)
Se _scrcpy_ si interrompe con l'avviso "Device disconnected", allora la connessione `adb` è stata chiusa.
Prova con un altro cavo USB o inseriscilo in un'altra porta USB. Vedi [#281] (in inglese) e [#283] (in inglese).
[#281]: https://github.com/Genymobile/scrcpy/issues/281
[#283]: https://github.com/Genymobile/scrcpy/issues/283
## Problemi di controllo
### Mouse e tastiera non funzionano
Su alcuni dispositivi potresti dover abilitare un opzione che permette l'[input simulato][simulating input] (link in inglese). Nelle opzioni sviluppatore, abilita:
> **Debug USB (Impostazioni di sicurezza)**
> _Permetti la concessione dei permessi e la simulazione degli input mediante il debug USB_
<!--- Ho tradotto personalmente il testo sopra, non conosco esattamente il testo reale --->
[simulating input]: https://github.com/Genymobile/scrcpy/issues/70#issuecomment-373286323
### I caratteri speciali non funzionano
Iniettare del testo in input è [limitato ai caratteri ASCII][text-input] (link in inglese). Un trucco permette di iniettare dei [caratteri accentati][accented-characters] (link in inglese), ma questo è tutto. Vedi [#37] (link in inglese).
[text-input]: https://github.com/Genymobile/scrcpy/issues?q=is%3Aopen+is%3Aissue+label%3Aunicode
[accented-characters]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-accented-characters
[#37]: https://github.com/Genymobile/scrcpy/issues/37
## Problemi del client
### La qualità è bassa
Se la definizione della finestra del tuo client è minore di quella del tuo dispositivo, allora potresti avere una bassa qualità di visualizzazione, specialmente individuabile nei testi (vedi [#40] (link in inglese)).
[#40]: https://github.com/Genymobile/scrcpy/issues/40
Per migliorare la qualità di ridimensionamento (downscaling), il filtro trilineare è applicato automaticamente se il renderizzatore è OpenGL e se supporta la creazione di mipmap.
In Windows, potresti voler forzare OpenGL:
```
scrcpy --render-driver=opengl
```
Potresti anche dover configurare il [comportamento di ridimensionamento][scaling behavior] (link in inglese):
> `scrcpy.exe` > Propietà > Compatibilità > Modifica impostazioni DPI elevati > Esegui l'override del comportamento di ridimensionamento DPI elevati > Ridimensionamento eseguito per: _Applicazione_.
[scaling behavior]: https://github.com/Genymobile/scrcpy/issues/40#issuecomment-424466723
### Crash del compositore KWin
In Plasma Desktop, il compositore è disabilitato mentre _scrcpy_ è in esecuzione.
Come soluzione alternativa, [disattiva la "composizione dei blocchi"][kwin] (link in inglese).
<!--- Non sono sicuro di aver tradotto correttamente la stringa di testo del pulsante --->
[kwin]: https://github.com/Genymobile/scrcpy/issues/114#issuecomment-378778613
## Crash
### Eccezione
Ci potrebbero essere molte ragioni. Una causa comune è che il codificatore hardware del tuo dispositivo non riesce a codificare alla definizione selezionata:
> ```
> ERROR: Exception on thread Thread[main,5,main]
> android.media.MediaCodec$CodecException: Error 0xfffffc0e
> ...
> Exit due to uncaughtException in main thread:
> ERROR: Could not open video stream
> INFO: Initial texture: 1080x2336
> ```
o
> ```
> ERROR: Exception on thread Thread[main,5,main]
> java.lang.IllegalStateException
> at android.media.MediaCodec.native_dequeueOutputBuffer(Native Method)
> ```
Prova con una definizione inferiore:
```
scrcpy -m 1920
scrcpy -m 1024
scrcpy -m 800
```
Potresti anche provare un altro [codificatore](README.it.md#codificatore).
## Linea di comando in Windows
Alcuni utenti Windows non sono familiari con la riga di comando. Qui è descritto come aprire un terminale ed eseguire `scrcpy` con gli argomenti:
1. Premi <kbd>Windows</kbd>+<kbd>r</kbd>, questo apre una finestra di dialogo.
2. Scrivi `cmd` e premi <kbd>Enter</kbd>, questo apre un terminale.
3. Vai nella tua cartella di _scrcpy_ scrivendo (adatta il percorso):
```bat
cd C:\Users\user\Downloads\scrcpy-win64-xxx
```
e premi <kbd>Enter</kbd>
4. Scrivi il tuo comando. Per esempio:
```bat
scrcpy --record file.mkv
```
Se pianifichi di utilizzare sempre gli stessi argomenti, crea un file `myscrcpy.bat` (abilita mostra [estensioni nomi file][show file extensions] per evitare di far confusione) contenente il tuo comando nella cartella di `scrcpy`. Per esempio:
```bat
scrcpy --prefer-text --turn-screen-off --stay-awake
```
Poi fai doppio click su quel file.
Potresti anche modificare (una copia di) `scrcpy-console.bat` o `scrcpy-noconsole.vbs` per aggiungere alcuni argomenti.

# 常见问题
这里是一些常见的问题以及他们的状态。
## `adb` 相关问题
`scrcpy` 执行 `adb` 命令来初始化和设备之间的连接。如果`adb` 执行失败了, scrcpy 就无法工作。
在这种情况中,将会输出这个错误:
> ERROR: "adb push" returned with value 1
这通常不是 _scrcpy_ 的bug而是你的环境的问题。
要找出原因,请执行以下操作:
```bash
adb devices
```
### 找不到`adb`
你的`PATH`中需要能访问到`adb`
在Windows上当前目录会包含在`PATH`中,并且`adb.exe`也包含在发行版中,因此它应该是开箱即用(直接解压就可以)的。
### 设备未授权
参见这里 [stackoverflow][device-unauthorized].
[device-unauthorized]: https://stackoverflow.com/questions/23081263/adb-android-device-unauthorized
### 未检测到设备
> adb: error: failed to get feature set: no devices/emulators found
确认已经正确启用 [adb debugging][enable-adb].
如果你的设备没有被检测到,你可能需要一些[驱动][drivers] (在 Windows上).
[enable-adb]: https://developer.android.com/studio/command-line/adb.html#Enabling
[drivers]: https://developer.android.com/studio/run/oem-usb.html
### 已连接多个设备
如果连接了多个设备,您将遇到以下错误:
> adb: error: failed to get feature set: more than one device/emulator
必须提供要镜像的设备的标识符:
```bash
scrcpy -s 01234567890abcdef
```
注意,如果你的设备是通过 TCP/IP 连接的, 你将会收到以下消息:
> adb: error: more than one device/emulator
> ERROR: "adb reverse" returned with value 1
> WARN: 'adb reverse' failed, fallback to 'adb forward'
这是意料之中的 (由于旧版安卓的一个bug, 请参见 [#5])但是在这种情况下scrcpy会退回到另一种方法这种方法应该可以起作用。
[#5]: https://github.com/Genymobile/scrcpy/issues/5
### adb版本之间冲突
> adb server version (41) doesn't match this client (39); killing...
同时使用多个版本的`adb`时会发生此错误。你必须查找使用不同`adb`版本的程序,并在所有地方使用相同版本的`adb`
你可以覆盖另一个程序中的`adb`二进制文件,或者通过设置`ADB`环境变量来让 _scrcpy_ 使用特定的`adb`二进制文件。
```bash
set ADB=/path/to/your/adb
scrcpy
```
### 设备断开连接
如果 _scrcpy_ 在警告“设备连接断开”的情况下自动中止,那就意味着`adb`连接已经断开了。
请尝试使用另一条USB线或者电脑上的另一个USB接口。
请参看 [#281] 和 [#283]。
[#281]: https://github.com/Genymobile/scrcpy/issues/281
[#283]: https://github.com/Genymobile/scrcpy/issues/283
## 控制相关问题
### 鼠标和键盘不起作用
在某些设备上,您可能需要启用一个选项以允许 [模拟输入][simulating input]。
在开发者选项中,打开:
> **USB调试 (安全设置)**
> _允许通过USB调试修改权限或模拟点击_
[simulating input]: https://github.com/Genymobile/scrcpy/issues/70#issuecomment-373286323
### 特殊字符不起作用
可输入的文本[被限制为ASCII字符][text-input]。也可以用一些小技巧输入一些[带重音符号的字符][accented-characters],但是仅此而已。参见[#37]。
[text-input]: https://github.com/Genymobile/scrcpy/issues?q=is%3Aopen+is%3Aissue+label%3Aunicode
[accented-characters]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-accented-characters
[#37]: https://github.com/Genymobile/scrcpy/issues/37
## 客户端相关问题
### 效果很差
如果你的客户端窗口分辨率比你的设备屏幕小,则可能出现效果差的问题,尤其是在文本上(参见 [#40])。
[#40]: https://github.com/Genymobile/scrcpy/issues/40
为了提升降尺度的质量如果渲染器是OpenGL并且支持mip映射就会自动开启三线性过滤。
在Windows上你可能希望强制使用OpenGL
```
scrcpy --render-driver=opengl
```
你可能还需要配置[缩放行为][scaling behavior]
> `scrcpy.exe` > Properties > Compatibility > Change high DPI settings >
> Override high DPI scaling behavior > Scaling performed by: _Application_.
[scaling behavior]: https://github.com/Genymobile/scrcpy/issues/40#issuecomment-424466723
### Wayland相关的问题
在Linux上SDL默认使用x11。可以通过`SDL_VIDEODRIVER`环境变量来更改[视频驱动][video driver]
[video driver]: https://wiki.libsdl.org/FAQUsingSDL#how_do_i_choose_a_specific_video_driver
```bash
export SDL_VIDEODRIVER=wayland
scrcpy
```
在一些发行版上 (至少包括 Fedora) `libdecor` 包必须手动安装。
参见 [#2554] 和 [#2559]。

### KWin compositor 崩溃
在Plasma桌面中_scrcpy_ 运行时会禁用compositor。
一种解决方法是, [禁用 "Block compositing"][kwin].
[kwin]: https://github.com/Genymobile/scrcpy/issues/114#issuecomment-378778613
## 崩溃
### 异常
可能有很多原因。一个常见的原因是您的设备无法按给定清晰度进行编码:
> ```
> ERROR: Exception on thread Thread[main,5,main]
> android.media.MediaCodec$CodecException: Error 0xfffffc0e
> ...
> Exit due to uncaughtException in main thread:
> ERROR: Could not open video stream
> INFO: Initial texture: 1080x2336
> ```
或者
> ```
> ERROR: Exception on thread Thread[main,5,main]
> java.lang.IllegalStateException
> at android.media.MediaCodec.native_dequeueOutputBuffer(Native Method)
> ```
请尝试使用更低的清晰度:
```
scrcpy -m 1920
scrcpy -m 1024
scrcpy -m 800
```
你也可以尝试另一种 [编码器](README.md#encoder)。
## Windows命令行
一些Windows用户不熟悉命令行。以下是如何打开终端并带参数执行`scrcpy`
1. 按下 <kbd>Windows</kbd>+<kbd>r</kbd>,打开一个对话框。
2. 输入 `cmd` 并按 <kbd>Enter</kbd>,这样就打开了一个终端。
3. 通过输入以下命令,切换到你的 _scrcpy_ 所在的目录 (根据你的实际位置修改路径):
```bat
cd C:\Users\user\Downloads\scrcpy-win64-xxx
```
然后按 <kbd>Enter</kbd>
4. 输入你的命令。比如:
```bat
scrcpy --record file.mkv
```
如果你打算总是使用相同的参数,在`scrcpy`目录创建一个文件 `myscrcpy.bat`
(启用 [显示文件拓展名][show file extensions] 避免混淆),文件中包含你的命令。例如:
```bat
scrcpy --prefer-text --turn-screen-off --stay-awake

## Esecuzione
Collega un dispositivo Android ed esegui:
```bash
scrcpy
```
Scrcpy accetta argomenti da riga di comando, essi sono listati con:
```bash
scrcpy --help
```
## Funzionalità
### Configurazione di acquisizione
#### Riduci dimensione
Qualche volta è utile trasmettere un dispositvo Android ad una definizione inferiore per aumentare le prestazioni.
Per limitare sia larghezza che altezza ad un certo valore (ad es. 1024):
```bash
scrcpy --max-size 1024
scrcpy -m 1024 # versione breve
```
L'altra dimensione è calcolata in modo tale che il rapporto di forma del dispositivo sia preservato.
In questo esempio un dispositivo in 1920x1080 viene trasmesso a 1024x576.
#### Cambia bit-rate (velocità di trasmissione)
Il bit-rate predefinito è 8 Mbps. Per cambiare il bitrate video (ad es. a 2 Mbps):
```bash
scrcpy --bit-rate 2M
scrcpy -b 2M # versione breve
```
#### Limitare il frame rate (frequenza di fotogrammi)
Il frame rate di acquisizione può essere limitato:
```bash
scrcpy --max-fps 15
```
Questo è supportato ufficialmente a partire da Android 10, ma potrebbe funzionare in versioni precedenti.
#### Ritaglio
Lo schermo del dispositivo può essere ritagliato per visualizzare solo parte di esso.
Questo può essere utile, per esempio, per trasmettere solo un occhio dell'Oculus Go:
```bash
scrcpy --crop 1224:1440:0:0 # 1224x1440 at offset (0,0)
```
Se anche `--max-size` è specificata, il ridimensionamento è applicato dopo il ritaglio.
#### Blocca orientamento del video
Per bloccare l'orientamento della trasmissione:
```bash
scrcpy --lock-video-orientation 0 # orientamento naturale
scrcpy --lock-video-orientation 1 # 90° antiorario
scrcpy --lock-video-orientation 2 # 180°
scrcpy --lock-video-orientation 3 # 90° orario
```
Questo influisce sull'orientamento della registrazione.
La [finestra può anche essere ruotata](#rotazione) indipendentemente.
#### Codificatore
Alcuni dispositivi hanno più di un codificatore e alcuni di questi possono provocare problemi o crash. È possibile selezionare un encoder diverso:
```bash
scrcpy --encoder OMX.qcom.video.encoder.avc
```
Per elencare i codificatori disponibili puoi immettere un nome di codificatore non valido e l'errore mostrerà i codificatori disponibili:
```bash
scrcpy --encoder _
```
### Registrazione
È possibile registrare lo schermo durante la trasmissione:
```bash
scrcpy --record file.mp4
scrcpy -r file.mkv
```
Per disabilitare la trasmissione durante la registrazione:
```bash
scrcpy --no-display --record file.mp4
scrcpy -Nr file.mkv
# interrompere la registrazione con Ctrl+C
```
I "fotogrammi saltati" sono registrati nonostante non siano mostrati in tempo reale (per motivi di prestazioni). I fotogrammi sono _datati_ sul dispositivo, così una [variazione di latenza dei pacchetti][packet delay variation] non impatta il file registrato.
[packet delay variation]: https://en.wikipedia.org/wiki/Packet_delay_variation
### Connessione
#### Wireless
_Scrcpy_ usa `adb` per comunicare col dispositivo e `adb` può [connettersi][connect] al dispositivo mediante TCP/IP:
1. Connetti il dispositivo alla stessa rete Wi-Fi del tuo computer.
2. Trova l'indirizzo IP del tuo dispositivo in Impostazioni → Informazioni sul telefono → Stato, oppure eseguendo questo comando:
```bash
adb shell ip route | awk '{print $9}'
```
3. Abilita adb via TCP/IP sul tuo dispositivo: `adb tcpip 5555`.
4. Scollega il tuo dispositivo.
5. Connetti il tuo dispositivo: `adb connect IP_DISPOSITVO:5555` _(rimpiazza `IP_DISPOSITIVO`)_.
6. Esegui `scrcpy` come al solito.
Potrebbe essere utile diminuire il bit-rate e la definizione
```bash
scrcpy --bit-rate 2M --max-size 800
scrcpy -b2M -m800 # versione breve
```
[connect]: https://developer.android.com/studio/command-line/adb.html#wireless
#### Multi dispositivo
Se in `adb devices` sono listati più dispositivi, è necessario specificare il _seriale_:
```bash
scrcpy --serial 0123456789abcdef
scrcpy -s 0123456789abcdef # versione breve
```
Se il dispositivo è collegato mediante TCP/IP:
```bash
scrcpy --serial 192.168.0.1:5555
scrcpy -s 192.168.0.1:5555 # versione breve
```
Puoi avviare più istanze di _scrcpy_ per diversi dispositivi.
#### Avvio automativo alla connessione del dispositivo
Potresti usare [AutoAdb]:
```bash
autoadb scrcpy -s '{}'
```
[AutoAdb]: https://github.com/rom1v/autoadb
#### Tunnel SSH
Per connettersi a un dispositivo remoto è possibile collegare un client `adb` locale ad un server `adb` remoto (assunto che entrambi stiano usando la stessa versione del protocollo _adb_):
```bash
adb kill-server # termina il server adb locale su 5037
ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
# tieni questo aperto
```
Da un altro terminale:
```bash
scrcpy
```
Per evitare l'abilitazione dell'apertura porte remota potresti invece forzare una "forward connection" (notare il `-L` invece di `-R`)
```bash
adb kill-server # termina il server adb locale su 5037
ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 your_remote_computer
# tieni questo aperto
```
Da un altro terminale:
```bash
scrcpy --force-adb-forward
```
Come per le connessioni wireless potrebbe essere utile ridurre la qualità:
```
scrcpy -b2M -m800 --max-fps 15
```
### Configurazione della finestra
#### Titolo
Il titolo della finestra è il modello del dispositivo per impostazione predefinita. Esso può essere cambiato:
```bash
scrcpy --window-title 'My device'
```
#### Posizione e dimensione
La posizione e la dimensione iniziale della finestra può essere specificata:
```bash
scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
```
#### Senza bordi
Per disabilitare le decorazioni della finestra:
```bash
scrcpy --window-borderless
```
#### Sempre in primo piano
Per tenere scrcpy sempre in primo piano:
```bash
scrcpy --always-on-top
```
#### Schermo intero
L'app può essere avviata direttamente a schermo intero:
```bash
scrcpy --fullscreen
scrcpy -f # versione breve
```
Lo schermo intero può anche essere attivato/disattivato con <kbd>MOD</kbd>+<kbd>f</kbd>.
#### Rotazione
La finestra può essere ruotata:
```bash
scrcpy --rotation 1
```
I valori possibili sono:
- `0`: nessuna rotazione
- `1`: 90 gradi antiorari
- `2`: 180 gradi
- `3`: 90 gradi orari
La rotazione può anche essere cambiata dinamicamente con <kbd>MOD</kbd>+<kbd>←</kbd>
_(sinistra)_ e <kbd>MOD</kbd>+<kbd>→</kbd> _(destra)_.
Notare che _scrcpy_ gestisce 3 diversi tipi di rotazione:
- <kbd>MOD</kbd>+<kbd>r</kbd> richiede al dispositvo di cambiare tra orientamento verticale (portrait) e orizzontale (landscape) (l'app in uso potrebbe rifiutarsi se non supporta l'orientamento richiesto).
- [`--lock-video-orientation`](#blocca-orientamento-del-video) cambia l'orientamento della trasmissione (l'orientamento del video inviato dal dispositivo al computer). Questo influenza la registrazione.
- `--rotation` (o <kbd>MOD</kbd>+<kbd>←</kbd>/<kbd>MOD</kbd>+<kbd>→</kbd>) ruota solo il contenuto della finestra. Questo influenza solo la visualizzazione, non la registrazione.
### Altre opzioni di trasmissione
#### "Sola lettura"
Per disabilitare i controlli (tutto ciò che può interagire col dispositivo: tasti di input, eventi del mouse, trascina e rilascia (drag&drop) file):
```bash
scrcpy --no-control
scrcpy -n
```
#### Schermo
Se sono disponibili più schermi, è possibile selezionare lo schermo da trasmettere:
```bash
scrcpy --display 1
```
La lista degli id schermo può essere ricavata da:
```bash
adb shell dumpsys display # cerca "mDisplayId=" nell'output
```
Lo schermo secondario potrebbe essere possibile controllarlo solo se il dispositivo esegue almeno Android 10 (in caso contrario è trasmesso in modalità sola lettura).
#### Mantenere sbloccato
Per evitare che il dispositivo si blocchi dopo un po' che il dispositivo è collegato:
```bash
scrcpy --stay-awake
scrcpy -w
```
Lo stato iniziale è ripristinato quando scrcpy viene chiuso.
#### Spegnere lo schermo
È possibile spegnere lo schermo del dispositivo durante la trasmissione con un'opzione da riga di comando:
```bash
scrcpy --turn-screen-off
scrcpy -S
```
Oppure premendo <kbd>MOD</kbd>+<kbd>o</kbd> in qualsiasi momento.
Per riaccenderlo premere <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd>.
In Android il pulsante `POWER` (tasto di accensione) accende sempre lo schermo. Per comodità, se `POWER` è inviato via scrcpy (con click destro o con <kbd>MOD</kbd>+<kbd>p</kbd>), si forza il dispositivo a spegnere lo schermo dopo un piccolo ritardo (appena possibile).
Il pulsante fisico `POWER` continuerà ad accendere lo schermo normalmente.
Può anche essere utile evitare il blocco del dispositivo:
```bash
scrcpy --turn-screen-off --stay-awake
scrcpy -Sw
```
#### Renderizzare i fotogrammi scaduti
Per minimizzare la latenza _scrcpy_ renderizza sempre l'ultimo fotogramma decodificato disponibile in maniera predefinita e tralascia quelli precedenti.
Per forzare la renderizzazione di tutti i fotogrammi (a costo di una possibile latenza superiore), utilizzare:
```bash
scrcpy --render-expired-frames
```
#### Mostrare i tocchi
Per le presentazioni può essere utile mostrare i tocchi fisici (sul dispositivo fisico).
Android fornisce questa funzionalità nelle _Opzioni sviluppatore_.
_Scrcpy_ fornisce un'opzione per abilitare questa funzionalità all'avvio e ripristinare il valore iniziale alla chiusura:
```bash
scrcpy --show-touches
scrcpy -t
```
Notare che mostra solo i tocchi _fisici_ (con le dita sul dispositivo).
#### Disabilitare il salvaschermo
In maniera predefinita scrcpy non previene l'attivazione del salvaschermo del computer.
Per disabilitarlo:
```bash
scrcpy --disable-screensaver
```
### Input di controlli
#### Rotazione dello schermo del dispostivo
Premere <kbd>MOD</kbd>+<kbd>r</kbd> per cambiare tra le modalità verticale (portrait) e orizzontale (landscape).
Notare che la rotazione avviene solo se l'applicazione in primo piano supporta l'orientamento richiesto.
#### Copia-incolla
Quando gli appunti di Android cambiano, essi vengono automaticamente sincronizzati con gli appunti del computer.
Qualsiasi scorciatoia <kbd>Ctrl</kbd> viene inoltrata al dispositivo. In particolare:
- <kbd>Ctrl</kbd>+<kbd>c</kbd> copia
- <kbd>Ctrl</kbd>+<kbd>x</kbd> taglia
- <kbd>Ctrl</kbd>+<kbd>v</kbd> incolla (dopo la sincronizzazione degli appunti da computer a dispositivo)
Questo solitamente funziona nella maniera più comune.
Il comportamento reale, però, dipende dall'applicazione attiva. Per esempio _Termux_ invia SIGINT con <kbd>Ctrl</kbd>+<kbd>c</kbd>, e _K-9 Mail_ compone un nuovo messaggio.
Per copiare, tagliare e incollare in questi casi (ma è solo supportato in Android >= 7):
- <kbd>MOD</kbd>+<kbd>c</kbd> inietta `COPY`
- <kbd>MOD</kbd>+<kbd>x</kbd> inietta `CUT`
- <kbd>MOD</kbd>+<kbd>v</kbd> inietta `PASTE` (dopo la sincronizzazione degli appunti da computer a dispositivo)
In aggiunta, <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> permette l'iniezione del testo degli appunti del computer come una sequenza di eventi pressione dei tasti. Questo è utile quando il componente non accetta l'incollaggio di testo (per esempio in _Termux_), ma questo può rompere il contenuto non ASCII.
**AVVISO:** Incollare gli appunti del computer nel dispositivo (sia con <kbd>Ctrl</kbd>+<kbd>v</kbd> che con <kbd>MOD</kbd>+<kbd>v</kbd>) copia il contenuto negli appunti del dispositivo. Come conseguenza, qualsiasi applicazione Android potrebbe leggere il suo contenuto. Dovresti evitare di incollare contenuti sensibili (come password) in questa maniera.
Alcuni dispositivi non si comportano come aspettato quando si modificano gli appunti del dispositivo a livello di codice. L'opzione `--legacy-paste` è fornita per cambiare il comportamento di <kbd>Ctrl</kbd>+<kbd>v</kbd> and <kbd>MOD</kbd>+<kbd>v</kbd> in modo tale che anch'essi iniettino il testo gli appunti del computer come una sequenza di eventi pressione dei tasti (nella stessa maniera di <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd>).
#### Pizzica per zoomare (pinch-to-zoom)
Per simulare il "pizzica per zoomare": <kbd>Ctrl</kbd>+_click e trascina_.
Più precisamente, tieni premuto <kbd>Ctrl</kbd> mentre premi il pulsante sinistro. Finchè il pulsante non sarà rilasciato, tutti i movimenti del mouse ridimensioneranno e ruoteranno il contenuto (se supportato dall'applicazione) relativamente al centro dello schermo.
Concretamente scrcpy genera degli eventi di tocco addizionali di un "dito virtuale" nella posizione simmetricamente opposta rispetto al centro dello schermo.
#### Preferenze di iniezione del testo
Ci sono due tipi di [eventi][textevents] generati quando si scrive testo:
- _eventi di pressione_, segnalano che tasto è stato premuto o rilasciato;
- _eventi di testo_, segnalano che del testo è stato inserito.
In maniera predefinita le lettere sono "iniettate" usando gli eventi di pressione, in maniera tale che la tastiera si comporti come aspettato nei giochi (come accade solitamente per i tasti WASD).
Questo, però, può [causare problemi][prefertext]. Se incontri un problema del genere, puoi evitarlo con:
```bash
scrcpy --prefer-text
```
(ma questo romperà il normale funzionamento della tastiera nei giochi)
[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
#### Ripetizione di tasti
In maniera predefinita tenere premuto un tasto genera una ripetizione degli eventi di pressione di tale tasto. Questo può creare problemi di performance in alcuni giochi, dove questi eventi sono inutilizzati.
Per prevenire l'inoltro ripetuto degli eventi di pressione:
```bash
scrcpy --no-key-repeat
```
#### Click destro e click centrale
In maniera predefinita, click destro aziona BACK (indietro) e il click centrale aziona HOME. Per disabilitare queste scorciatoie e, invece, inviare i click al dispositivo:
```bash
scrcpy --forward-all-clicks
```
### Rilascio di file
#### Installare APK
Per installare un APK, trascina e rilascia un file APK (finisce con `.apk`) nella finestra di _scrcpy_.
Non c'è alcuna risposta visiva, un log è stampato nella console.
#### Trasferimento di file verso il dispositivo
Per trasferire un file in `/sdcard/` del dispositivo trascina e rilascia un file (non APK) nella finestra di _scrcpy_.
Non c'è alcuna risposta visiva, un log è stampato nella console.
La cartella di destinazione può essere cambiata all'avvio:
```bash
scrcpy --push-target=/sdcard/Download/
```
### Inoltro dell'audio
L'audio non è inoltrato da _scrcpy_. Usa [sndcpy].
Vedi anche la [issue #14].
[sndcpy]: https://github.com/rom1v/sndcpy
[issue #14]: https://github.com/Genymobile/scrcpy/issues/14
## Scociatoie
Nella lista seguente, <kbd>MOD</kbd> è il modificatore delle scorciatoie. In maniera predefinita è <kbd>Alt</kbd> (sinistro) o <kbd>Super</kbd> (sinistro).
Può essere cambiato usando `--shortcut-mod`. I tasti possibili sono `lctrl`, `rctrl`, `lalt`, `ralt`, `lsuper` and `rsuper` (`l` significa sinistro e `r` significa destro). Per esempio:
```bash
# usa ctrl destro per le scorciatoie
scrcpy --shortcut-mod=rctrl
# use sia "ctrl sinistro"+"alt sinistro" che "super sinistro" per le scorciatoie
scrcpy --shortcut-mod=lctrl+lalt,lsuper
```
_<kbd>[Super]</kbd> è il pulsante <kbd>Windows</kbd> o <kbd>Cmd</kbd>._
[Super]: https://it.wikipedia.org/wiki/Tasto_Windows
<!-- https://en.wikipedia.org/wiki/Super_key_(keyboard_button) è la pagina originale di Wikipedia inglese, l'ho sostituita con una simile in quello italiano -->

Tutte le scorciatoie <kbd>Ctrl</kbd>+_tasto_ sono inoltrate al dispositivo, così sono gestite dall'applicazione attiva.
## Path personalizzati
Per utilizzare dei binari _adb_ specifici, configura il suo path nella variabile d'ambente `ADB`:
```bash
ADB=/percorso/per/adb scrcpy
```
Per sovrascrivere il percorso del file `scrcpy-server`, configura il percorso in `SCRCPY_SERVER_PATH`.
## Perchè _scrcpy_?
Un collega mi ha sfidato a trovare un nome tanto impronunciabile quanto [gnirehtet].
[`strcpy`] copia una **str**ing (stringa); `scrcpy` copia uno **scr**een (schermo).
[gnirehtet]: https://github.com/Genymobile/gnirehtet

# Homebrew >= 2.6.0
brew install --cask android-platform-tools
# Homebrew < 2.6.0
brew cask install android-platform-tools
```
また、[アプリケーションをビルド][BUILD]することも可能です。
## 実行
Androidデバイスを接続し、実行:
```bash
scrcpy
```
次のコマンドでリストされるコマンドライン引数も受け付けます:
```bash
scrcpy --help
```
## 機能
### キャプチャ構成
#### サイズ削減
Androidデバイスを低解像度でミラーリングする場合、パフォーマンス向上に便利な場合があります。
幅と高さをある値(例1024)に制限するには:
```bash
scrcpy --max-size 1024
scrcpy -m 1024 # 短縮版
```
一方のサイズはデバイスのアスペクト比が維持されるように計算されます。この方法では、1920x1080のデバイスでは1024x576にミラーリングされます。
#### ビットレート変更
ビットレートの初期値は8Mbpsです。ビットレートを変更するには(例:2Mbpsに変更):
```bash
scrcpy --bit-rate 2M
scrcpy -b 2M # 短縮版
```
#### フレームレート制限
キャプチャするフレームレートを制限できます:
```bash
scrcpy --max-fps 15
```
この機能はAndroid 10からオフィシャルサポートとなっていますが、以前のバージョンでも動作する可能性があります。
#### トリミング
デバイスの画面は、画面の一部のみをミラーリングするようにトリミングできます。
これは、例えばOculus Goの片方の目をミラーリングする場合に便利です。:
```bash
scrcpy --crop 1224:1440:0:0 # オフセット位置(0,0)で1224x1440
```
もし`--max-size`も指定されている場合、トリミング後にサイズ変更が適用されます。
#### ビデオの向きをロックする
ミラーリングの向きをロックするには:
```bash
scrcpy --lock-video-orientation 0 # 自然な向き
scrcpy --lock-video-orientation 1 # 90°反時計回り
scrcpy --lock-video-orientation 2 # 180°
scrcpy --lock-video-orientation 3 # 90°時計回り
```
この設定は録画の向きに影響します。
[ウィンドウは独立して回転することもできます](#回転)。
#### エンコーダ
いくつかのデバイスでは一つ以上のエンコーダを持ちます。それらのいくつかは、問題やクラッシュを引き起こします。別のエンコーダを選択することが可能です:
```bash
scrcpy --encoder OMX.qcom.video.encoder.avc
```
利用可能なエンコーダをリストするために、無効なエンコーダ名を渡すことができます。エラー表示で利用可能なエンコーダを提供します。
```bash
scrcpy --encoder _
```
### 録画
ミラーリング中に画面の録画をすることが可能です:
```bash
scrcpy --record file.mp4
scrcpy -r file.mkv
```
録画中にミラーリングを無効にするには:
```bash
scrcpy --no-display --record file.mp4
scrcpy -Nr file.mkv
# Ctrl+Cで録画を中断する
```
"スキップされたフレーム"は(パフォーマンス上の理由で)リアルタイムで表示されなくても録画されます。
フレームはデバイス上で _タイムスタンプされる_ ため [パケット遅延のバリエーション] は録画されたファイルに影響を与えません。
[パケット遅延のバリエーション]: https://en.wikipedia.org/wiki/Packet_delay_variation
### 接続
#### ワイヤレス
_Scrcpy_ はデバイスとの通信に`adb`を使用します。そして`adb`はTCP/IPを介しデバイスに[接続]することができます:
1. あなたのコンピュータと同じWi-Fiに接続します。
2. あなたのIPアドレスを取得します。設定 → 端末情報 → ステータス情報、もしくは、このコマンドを実行します:
```bash
adb shell ip route | awk '{print $9}'
```
3. あなたのデバイスでTCP/IPを介したadbを有効にします: `adb tcpip 5555`
4. あなたのデバイスの接続を外します。
5. あなたのデバイスに接続します:
`adb connect DEVICE_IP:5555` _(`DEVICE_IP`は置き換える)_
6. 通常通り`scrcpy`を実行します。
この方法はビットレートと解像度を減らすのにおそらく有用です:
```bash
scrcpy --bit-rate 2M --max-size 800
scrcpy -b2M -m800 # 短縮版
```
[接続]: https://developer.android.com/studio/command-line/adb.html#wireless
#### マルチデバイス
もし`adb devices`でいくつかのデバイスがリストされる場合、 _シリアルナンバー_ を指定する必要があります:
```bash
scrcpy --serial 0123456789abcdef
scrcpy -s 0123456789abcdef # 短縮版
```
デバイスがTCP/IPを介して接続されている場合:
```bash
scrcpy --serial 192.168.0.1:5555
scrcpy -s 192.168.0.1:5555 # 短縮版
```
複数のデバイスに対して、複数の _scrcpy_ インスタンスを開始することができます。
#### デバイス接続での自動起動
[AutoAdb]を使用可能です:
```bash
autoadb scrcpy -s '{}'
```
[AutoAdb]: https://github.com/rom1v/autoadb
#### SSHトンネル
リモートデバイスに接続するため、ローカル`adb`クライアントからリモート`adb`サーバーへ接続することが可能です(同じバージョンの _adb_ プロトコルを使用している場合):
```bash
adb kill-server # 5037ポートのローカルadbサーバーを終了する
ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
# オープンしたままにする
```
他の端末から:
```bash
scrcpy
```
リモートポート転送の有効化を回避するためには、代わりに転送接続を強制することができます(`-R`の代わりに`-L`を使用することに注意):
```bash
adb kill-server # 5037ポートのローカルadbサーバーを終了する
ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 your_remote_computer
# オープンしたままにする
```
他の端末から:
```bash
scrcpy --force-adb-forward
```
ワイヤレス接続と同様に、クオリティを下げると便利な場合があります:
```
scrcpy -b2M -m800 --max-fps 15
```
### ウィンドウ構成
#### タイトル
ウィンドウのタイトルはデバイスモデルが初期値です。これは変更できます:
```bash
scrcpy --window-title 'My device'
```
#### 位置とサイズ
ウィンドウの位置とサイズの初期値を指定できます:
```bash
scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
```
#### ボーダーレス
ウィンドウの装飾を無効化するには:
```bash
scrcpy --window-borderless
```
#### 常に画面のトップ
scrcpyの画面を常にトップにするには:
```bash
scrcpy --always-on-top
```
#### フルスクリーン
アプリケーションを直接フルスクリーンで開始できます:
```bash
scrcpy --fullscreen
scrcpy -f # 短縮版
```
フルスクリーンは、次のコマンドで動的に切り替えることができます <kbd>MOD</kbd>+<kbd>f</kbd>
#### 回転
ウィンドウは回転することができます:
```bash
scrcpy --rotation 1
```
設定可能な値:
- `0`: 回転なし
- `1`: 90° 反時計回り
- `2`: 180°
- `3`: 90° 時計回り
回転は次のコマンドで動的に変更することができます。 <kbd>MOD</kbd>+<kbd>←</kbd>_(左)_ 、 <kbd>MOD</kbd>+<kbd>→</kbd>_(右)_
_scrcpy_ は3つの回転を管理することに注意:
- <kbd>MOD</kbd>+<kbd>r</kbd>はデバイスに縦向きと横向きの切り替えを要求する(現在実行中のアプリで要求している向きをサポートしていない場合、拒否することがある)
- [`--lock-video-orientation`](#ビデオの向きをロックする)は、ミラーリングする向きを変更する(デバイスからPCへ送信される向き)。録画に影響します。
- `--rotation` (もしくは<kbd>MOD</kbd>+<kbd>←</kbd>/<kbd>MOD</kbd>+<kbd>→</kbd>)は、ウィンドウのコンテンツのみを回転します。これは表示にのみに影響し、録画には影響しません。
### 他のミラーリングオプション
#### Read-only リードオンリー
制御を無効にするには(デバイスと対話する全てのもの:入力キー、マウスイベント、ファイルのドラッグ&ドロップ):
```bash
scrcpy --no-control
scrcpy -n
```
#### ディスプレイ
いくつか利用可能なディスプレイがある場合、ミラーリングするディスプレイを選択できます:
```bash
scrcpy --display 1
```
ディスプレイIDのリストは次の方法で取得できます:
```
adb shell dumpsys display # search "mDisplayId=" in the output
```
セカンダリディスプレイは、デバイスが少なくともAndroid 10の場合にコントロール可能です。(それ以外ではリードオンリーでミラーリングされます)
#### 起動状態にする
デバイス接続時、少し遅れてからデバイスのスリープを防ぐには:
```bash
scrcpy --stay-awake
scrcpy -w
```
scrcpyが閉じられた時、初期状態に復元されます。
#### 画面OFF
コマンドラインオプションを使用することで、ミラーリングの開始時にデバイスの画面をOFFにすることができます:
```bash
scrcpy --turn-screen-off
scrcpy -S
```
もしくは、<kbd>MOD</kbd>+<kbd>o</kbd>を押すことでいつでもできます。
元に戻すには、<kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd>を押します。
Androidでは、`POWER`ボタンはいつでも画面を表示します。便宜上、`POWER`がscrcpyを介して(右クリックもしくは<kbd>MOD</kbd>+<kbd>p</kbd>を介して)送信される場合、(ベストエフォートベースで)少し遅れて、強制的に画面を非表示にします。ただし、物理的な`POWER`ボタンを押した場合は、画面は表示されます。
このオプションはデバイスがスリープしないようにすることにも役立ちます:
```bash
scrcpy --turn-screen-off --stay-awake
scrcpy -Sw
```
#### 期限切れフレームをレンダリングする
初期状態では、待ち時間を最小限にするために、_scrcpy_ は最後にデコードされたフレームをレンダリングし、前のフレームを削除します。
全フレームのレンダリングを強制するには(待ち時間が長くなる可能性があります):
```bash
scrcpy --render-expired-frames
```
#### タッチを表示
プレゼンテーションの場合(物理デバイス上で)物理的なタッチを表示すると便利な場合があります。
Androidはこの機能を _開発者オプション_ で提供します。
_Scrcpy_ は開始時にこの機能を有効にし、終了時に初期値を復元するオプションを提供します:
```bash
scrcpy --show-touches
scrcpy -t
```
(デバイス上で指を使った) _物理的な_ タッチのみ表示されることに注意してください。
#### スクリーンセーバー無効
初期状態では、scrcpyはコンピュータ上でスクリーンセーバーが実行される事を妨げません。
これを無効にするには:
```bash
scrcpy --disable-screensaver
```
### 入力制御
#### デバイス画面の回転
<kbd>MOD</kbd>+<kbd>r</kbd>を押すことで、縦向きと横向きを切り替えます。
フォアグラウンドのアプリケーションが要求された向きをサポートしている場合のみ回転することに注意してください。
#### コピー-ペースト
Androidのクリップボードが変更される度に、コンピュータのクリップボードに自動的に同期されます。
<kbd>Ctrl</kbd>のショートカットは全てデバイスに転送されます。特に:
- <kbd>Ctrl</kbd>+<kbd>c</kbd> 通常はコピーします
- <kbd>Ctrl</kbd>+<kbd>x</kbd> 通常はカットします
- <kbd>Ctrl</kbd>+<kbd>v</kbd> 通常はペーストします(コンピュータとデバイスのクリップボードが同期された後)
通常は期待通りに動作します。
しかしながら、実際の動作はアクティブなアプリケーションに依存します。例えば、_Termux_ は代わりに<kbd>Ctrl</kbd>+<kbd>c</kbd>でSIGINTを送信します、そして、_K-9 Mail_ は新しいメッセージを作成します。
このようなケースでコピー、カットそしてペーストをするには(Android 7以上でのサポートのみですが):
- <kbd>MOD</kbd>+<kbd>c</kbd> `COPY`を挿入
- <kbd>MOD</kbd>+<kbd>x</kbd> `CUT`を挿入
- <kbd>MOD</kbd>+<kbd>v</kbd> `PASTE`を挿入(コンピュータとデバイスのクリップボードが同期された後)
加えて、<kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd>はコンピュータのクリップボードテキストにキーイベントのシーケンスとして挿入することを許可します。これはコンポーネントがテキストのペーストを許可しない場合(例えば _Termux_)に有用ですが、非ASCIIコンテンツを壊す可能性があります。
**警告:** デバイスにコンピュータのクリップボードを(<kbd>Ctrl</kbd>+<kbd>v</kbd>または<kbd>MOD</kbd>+<kbd>v</kbd>を介して)ペーストすることは、デバイスのクリップボードにコンテンツをコピーします。結果としてどのAndoridアプリケーションもそのコンテンツを読み取ることができます。機密性の高いコンテンツ(例えばパスワードなど)をこの方法でペーストすることは避けてください。
プログラムでデバイスのクリップボードを設定した場合、一部のデバイスは期待どおりに動作しません。`--legacy-paste`オプションは、コンピュータのクリップボードテキストをキーイベントのシーケンスとして挿入するため(<kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd>と同じ方法)、<kbd>Ctrl</kbd>+<kbd>v</kbd>と<kbd>MOD</kbd>+<kbd>v</kbd>の動作の変更を提供します。
#### ピンチしてズームする
"ピンチしてズームする"をシミュレートするには: <kbd>Ctrl</kbd>+_クリック&移動_
より正確にするには、左クリックボタンを押している間、<kbd>Ctrl</kbd>を押したままにします。左クリックボタンを離すまで、全てのマウスの動きは、(アプリでサポートされている場合)画面の中心を基準として、コンテンツを拡大縮小および回転します。
具体的には、scrcpyは画面の中央を反転した位置にある"バーチャルフィンガー"から追加のタッチイベントを生成します。
#### テキストインジェクション環境設定
テキストをタイプした時に生成される2種類の[イベント][textevents]があります:
- _key events_ はキーを押したときと離したことを通知します。
- _text events_ はテキストが入力されたことを通知します。
初期状態で、文字はキーイベントで挿入されるため、キーボードはゲームで期待通りに動作します(通常はWASDキー)。
しかし、これは[問題を引き起こす][prefertext]かもしれません。もしこのような問題が発生した場合は、この方法で回避できます:
```bash
scrcpy --prefer-text
```
(しかしこの方法はゲームのキーボードの動作を壊します)
[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
#### キーの繰り返し
初期状態では、キーの押しっぱなしは繰り返しのキーイベントを生成します。これらのイベントが使われない場合でも、この方法は一部のゲームでパフォーマンスの問題を引き起す可能性があります。
繰り返しのキーイベントの転送を回避するためには:
```bash
scrcpy --no-key-repeat
```
#### 右クリックと真ん中クリック
初期状態では、右クリックはバックの動作(もしくはパワーオン)を起こし、真ん中クリックではホーム画面へ戻ります。このショートカットを無効にし、代わりにデバイスへクリックを転送するには:
```bash
scrcpy --forward-all-clicks
```
### ファイルのドロップ
#### APKのインストール
APKをインストールするには、(`.apk`で終わる)APKファイルを _scrcpy_ の画面にドラッグ&ドロップします。
見た目のフィードバックはありません。コンソールにログが出力されます。
#### デバイスにファイルを送る
デバイスの`/sdcard/`ディレクトリにファイルを送るには、(APKではない)ファイルを _scrcpy_ の画面にドラッグ&ドロップします。
見た目のフィードバックはありません。コンソールにログが出力されます。
転送先ディレクトリを起動時に変更することができます:
```bash
scrcpy --push-target /sdcard/foo/bar/
```
### 音声転送
音声は _scrcpy_ では転送されません。[sndcpy]を使用します。
[issue #14]も参照ください。
[sndcpy]: https://github.com/rom1v/sndcpy
[issue #14]: https://github.com/Genymobile/scrcpy/issues/14
## ショートカット
次のリストでは、<kbd>MOD</kbd>でショートカット変更します。初期状態では、(left)<kbd>Alt</kbd>または(left)<kbd>Super</kbd>です。
これは`--shortcut-mod`で変更することができます。可能なキーは`lctrl`、`rctrl`、`lalt`、 `ralt`、 `lsuper`そして`rsuper`です。例えば:
```bash
# RCtrlをショートカットとして使用します
scrcpy --shortcut-mod=rctrl
# ショートカットにLCtrl+LAltまたはLSuperのいずれかを使用します
scrcpy --shortcut-mod=lctrl+lalt,lsuper
```
_<kbd>[Super]</kbd>は通常<kbd>Windows</kbd>もしくは<kbd>Cmd</kbd>キーです。_
[Super]: https://en.wikipedia.org/wiki/Super_key_(keyboard_button)

_³Android 7以上のみ._
全ての<kbd>Ctrl</kbd>+_キー_ ショートカットはデバイスに転送されます、そのためアクティブなアプリケーションによって処理されます。
## カスタムパス
特定の _adb_ バイナリを使用する場合、そのパスを環境変数`ADB`で構成します:
ADB=/path/to/adb scrcpy
`scrcpy-server`ファイルのパスを上書きするには、`SCRCPY_SERVER_PATH`でそのパスを構成します。

## なぜ _scrcpy_?
同僚が私に、[gnirehtet]のように発音できない名前を見つけるように要求しました。
[`strcpy`]は**str**ingをコピーします。`scrcpy`は**scr**eenをコピーします。

#### v4l2loopback
On Linux, it is possible to send the video stream to a v4l2 loopback device, so
that the Android device can be opened like a webcam by any v4l2-capable tool.
The module `v4l2loopback` must be installed:
```bash
sudo apt install v4l2loopback-dkms
```
To create a v4l2 device:
```bash
sudo modprobe v4l2loopback
```
This will create a new video device in `/dev/videoN`, where `N` is an integer
(more [options](https://github.com/umlaeute/v4l2loopback#options) are available
to create several devices or devices with specific IDs).
To list the enabled devices:
```bash
# requires v4l-utils package
v4l2-ctl --list-devices
# simple but might be sufficient
ls /dev/video*
```
To start scrcpy using a v4l2 sink:
```bash
scrcpy --v4l2-sink=/dev/videoN
scrcpy --v4l2-sink=/dev/videoN --no-display # disable mirroring window
scrcpy --v4l2-sink=/dev/videoN -N # short version
```
(replace `N` by the device ID, check with `ls /dev/video*`)
Once enabled, you can open your video stream with a v4l2-capable tool:
```bash
ffplay -i /dev/videoN
vlc v4l2:///dev/videoN # VLC might add some buffering delay
```
For example, you could capture the video within [OBS].
[OBS]: https://obsproject.com/
#### Buffering
It is possible to add buffering. This increases latency but reduces jitter (see
#2464).
The option is available for display buffering:
```bash
scrcpy --display-buffer=50 # add 50 ms buffering for display
```
and V4L2 sink:
```bash

#### Physical keyboard simulation (HID)
By default, scrcpy uses Android key or text injection: it works everywhere, but
is limited to ASCII.
On Linux, scrcpy can simulate a USB physical keyboard on Android to provide a
better input experience (using [USB HID over AOAv2][hid-aoav2]): the virtual
keyboard is disabled and it works for all characters and IME.
[hid-aoav2]: https://source.android.com/devices/accessories/aoa2#hid-support
However, it only works if the device is connected by USB, and is currently only
supported on Linux.
To enable this mode:
```bash
scrcpy --hid-keyboard
scrcpy -K # short version
```
If it fails for some reason (for example because the device is not connected via
USB), it automatically fallbacks to the default mode (with a log in the
console). This allows to use the same command line options when connected over
USB and TCP/IP.
In this mode, raw key events (scancodes) are sent to the device, independently
of the host key mapping. Therefore, if your keyboard layout does not match, it
must be configured on the Android device, in Settings → System → Languages and
input → [Physical keyboard].

#### Display
#### Desligar a tela
Se vários displays estão disponíveis, é possível selecionar o display para
espelhar:
```bash
scrcpy --display 1
```
A lista de IDs dos displays pode ser obtida por:
```
adb shell dumpsys display # busca "mDisplayId=" na saída
```
O display secundário pode apenas ser controlado se o dispositivo roda pelo menos Android
10 (caso contrário é espelhado como apenas leitura).
#### Permanecer ativo
Para evitar que o dispositivo seja suspenso após um delay quando o dispositivo é conectado:
```bash
scrcpy --stay-awake
scrcpy -w
```
O estado inicial é restaurado quando o scrcpy é fechado.
#### Desligar tela
É possível desligar a tela do dispositivo durante o início do espelhamento com uma
opção de linha de comando:
É possível desligar a tela do dispositivo durante o início do espelhamento com uma opção de linha de comando:
```bash
scrcpy --turn-screen-off
scrcpy -S
```
Ou apertando <kbd>MOD</kbd>+<kbd>o</kbd> a qualquer momento.
Ou apertando `Ctrl`+`o` durante qualquer momento.
Para ligar novamente, pressione <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd>.
Para ligar novamente, pressione `POWER` (ou `Ctrl`+`p`).
No Android, o botão de `POWER` sempre liga a tela. Por conveniência, se
`POWER` é enviado via scrcpy (via clique-direito ou <kbd>MOD</kbd>+<kbd>p</kbd>), ele
forçará a desligar a tela após um delay pequeno (numa base de melhor esforço).
O botão `POWER` físico ainda causará a tela ser ligada.
#### Frames expirados de renderização
Também pode ser útil evitar que o dispositivo seja suspenso:
Por padrão, para minimizar a latência, _scrcpy_ sempre renderiza o último frame decodificado disponível e descarta o anterior.
```bash
scrcpy --turn-screen-off --stay-awake
scrcpy -Sw
```

Note que só será rotacionado se a aplicação em primeiro plano tiver suporte para o modo requisitado.
#### Copiar-colar
#### Copiar-Colar
Sempre que a área de transferência do Android muda, é automaticamente sincronizada com a
área de transferência do computador.
É possível sincronizar áreas de transferência entre computador e o dispositivo,
para ambas direções:
Qualquer atalho com <kbd>Ctrl</kbd> é encaminhado para o dispositivo. Em particular:
- <kbd>Ctrl</kbd>+<kbd>c</kbd> tipicamente copia
- <kbd>Ctrl</kbd>+<kbd>x</kbd> tipicamente recorta
- <kbd>Ctrl</kbd>+<kbd>v</kbd> tipicamente cola (após a sincronização de área de transferência
computador-para-dispositivo)
- `Ctrl`+`c` copia a área de transferência do dispositivo para a área de trasferência do computador;
- `Ctrl`+`Shift`+`v` copia a área de transferência do computador para a área de transferência do dispositivo;
- `Ctrl`+`v` _cola_ a área de transferência do computador como uma sequência de eventos de texto (mas
quebra caracteres não-ASCII).
Isso tipicamente funciona como esperado.
#### Preferências de injeção de texto
O comportamento de fato depende da aplicação ativa, no entanto. Por exemplo,
_Termux_ envia SIGINT com <kbd>Ctrl</kbd>+<kbd>c</kbd>, e _K-9 Mail_
compõe uma nova mensagem.
Para copiar, recortar e colar em tais casos (mas apenas suportado no Android >= 7):
- <kbd>MOD</kbd>+<kbd>c</kbd> injeta `COPY`
- <kbd>MOD</kbd>+<kbd>x</kbd> injeta `CUT`
- <kbd>MOD</kbd>+<kbd>v</kbd> injeta `PASTE` (após a sincronização de área de transferência
computador-para-dispositivo)
Em adição, <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> permite injetar o
texto da área de transferência do computador como uma sequência de eventos de tecla. Isso é útil quando o
componente não aceita colar texto (por exemplo no _Termux_), mas pode
quebrar conteúdo não-ASCII.
**ADVERTÊNCIA:** Colar a área de transferência do computador para o dispositivo (tanto via
<kbd>Ctrl</kbd>+<kbd>v</kbd> quanto <kbd>MOD</kbd>+<kbd>v</kbd>) copia o conteúdo
para a área de transferência do dispositivo. Como consequência, qualquer aplicação Android pode ler
o seu conteúdo. Você deve evitar colar conteúdo sensível (como senhas) dessa
forma.
Alguns dispositivos não se comportam como esperado quando a área de transferência é definida
programaticamente. Uma opção `--legacy-paste` é fornecida para mudar o comportamento
de <kbd>Ctrl</kbd>+<kbd>v</kbd> e <kbd>MOD</kbd>+<kbd>v</kbd> para que eles
também injetem o texto da área de transferência do computador como uma sequência de eventos de tecla (da mesma
forma que <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd>).
#### Pinçar para dar zoom
Para simular "pinçar para dar zoom": <kbd>Ctrl</kbd>+_clicar-e-mover_.
Mais precisamente, segure <kbd>Ctrl</kbd> enquanto pressiona o botão de clique-esquerdo. Até que
o botão de clique-esquerdo seja liberado, todos os movimentos do mouse ampliar e rotacionam o
conteúdo (se suportado pelo app) relativo ao centro da tela.
Concretamente, scrcpy gera eventos adicionais de toque de um "dedo virtual" em
uma posição invertida em relação ao centro da tela.
#### Preferência de injeção de texto
Existem dois tipos de [eventos][textevents] gerados ao digitar um texto:
- _eventos de tecla_, sinalizando que a tecla foi pressionada ou solta;

#### Repetir tecla
Por padrão, segurar uma tecla gera eventos de tecla repetidos. Isso pode causar
problemas de performance em alguns jogos, onde esses eventos são inúteis de qualquer forma.
Para evitar o encaminhamento eventos de tecla repetidos:
```bash
scrcpy --no-key-repeat
```
#### Clique-direito e clique-do-meio
Por padrão, clique-direito dispara BACK (ou POWER) e clique-do-meio dispara
HOME. Para desabilitar esses atalhos e encaminhar os cliques para o dispositivo:
```bash

## Atalhos
Na lista a seguir, <kbd>MOD</kbd> é o modificador de atalho. Por padrão, é
<kbd>Alt</kbd> (esquerdo) ou <kbd>Super</kbd> (esquerdo).
Ele pode ser mudado usando `--shortcut-mod`. Possíveis teclas são `lctrl`, `rctrl`,
`lalt`, `ralt`, `lsuper` e `rsuper`. Por exemplo:
```bash
# usar RCtrl para atalhos
scrcpy --shortcut-mod=rctrl
# usar tanto LCtrl+LAlt quanto LSuper para atalhos
scrcpy --shortcut-mod=lctrl+lalt,lsuper
```
_<kbd>[Super]</kbd> é tipicamente a tecla <kbd>Windows</kbd> ou <kbd>Cmd</kbd>._

## Ejecutar
Enchufa el dispositivo Android, y ejecuta:
```bash
scrcpy
```
Acepta argumentos desde la línea de comandos, listados en:
```bash
scrcpy --help
```
## Características
### Capturar configuración
#### Reducir la definición
A veces es útil reducir la definición de la imagen del dispositivo Android para aumentar el desempeño.
Para limitar el ancho y la altura a un valor específico (ej. 1024):
```bash
scrcpy --max-size 1024
scrcpy -m 1024 # versión breve
```
La otra dimensión es calculada para conservar el aspect ratio del dispositivo.
De esta forma, un dispositivo en 1920×1080 será transmitido a 1024×576.
#### Cambiar el bit-rate
El bit-rate por defecto es 8 Mbps. Para cambiar el bit-rate del video (ej. a 2 Mbps):
```bash
scrcpy --bit-rate 2M
scrcpy -b 2M # versión breve
```
#### Limitar los fps
El fps puede ser limitado:
```bash
scrcpy --max-fps 15
```
Es oficialmente soportado desde Android 10, pero puede funcionar en versiones anteriores.
#### Recortar
La imagen del dispositivo puede ser recortada para transmitir solo una parte de la pantalla.
Por ejemplo, puede ser útil para transmitir la imagen de un solo ojo del Oculus Go:
```bash
scrcpy --crop 1224:1440:0:0 # 1224x1440 con coordenadas de origen en (0,0)
```
Si `--max-size` también está especificado, el cambio de tamaño es aplicado después de cortar.
#### Fijar la rotación del video
Para fijar la rotación de la transmisión:
```bash
scrcpy --lock-video-orientation 0 # orientación normal
scrcpy --lock-video-orientation 1 # 90° contrarreloj
scrcpy --lock-video-orientation 2 # 180°
scrcpy --lock-video-orientation 3 # 90° sentido de las agujas del reloj
```
Esto afecta la rotación de la grabación.
La [ventana también puede ser rotada](#rotación) independientemente.
#### Codificador
Algunos dispositivos pueden tener más de una rotación, y algunos pueden causar problemas o errores. Es posible seleccionar un codificador diferente:
```bash
scrcpy --encoder OMX.qcom.video.encoder.avc
```
Para listar los codificadores disponibles, puedes pasar un nombre de codificador inválido, el error te dará los codificadores disponibles:
```bash
scrcpy --encoder _
```
### Grabación
Es posible grabar la pantalla mientras se transmite:
```bash
scrcpy --record file.mp4
scrcpy -r file.mkv
```
Para grabar sin transmitir la pantalla:
```bash
scrcpy --no-display --record file.mp4
scrcpy -Nr file.mkv
# interrumpe la grabación con Ctrl+C
```
"Skipped frames" son grabados, incluso si no son mostrados en tiempo real (por razones de desempeño). Los frames tienen _marcas de tiempo_ en el dispositivo, por lo que el "[packet delay
variation]" no impacta el archivo grabado.
[packet delay variation]: https://en.wikipedia.org/wiki/Packet_delay_variation
### Conexión
#### Inalámbrica
_Scrcpy_ usa `adb` para comunicarse con el dispositivo, y `adb` puede [conectarse] vía TCP/IP:
1. Conecta el dispositivo al mismo Wi-Fi que tu computadora.
2. Obtén la dirección IP del dispositivo, en Ajustes → Acerca del dispositivo → Estado, o ejecutando este comando:
```bash
adb shell ip route | awk '{print $9}'
```
3. Habilita adb vía TCP/IP en el dispositivo: `adb tcpip 5555`.
4. Desenchufa el dispositivo.
5. Conéctate a tu dispositivo: `adb connect IP_DEL_DISPOSITIVO:5555` _(reemplaza `IP_DEL_DISPOSITIVO`)_.
6. Ejecuta `scrcpy` con normalidad.
Podría resultar útil reducir el bit-rate y la definición:
```bash
scrcpy --bit-rate 2M --max-size 800
scrcpy -b2M -m800 # versión breve
```
[conectarse]: https://developer.android.com/studio/command-line/adb.html#wireless
#### Múltiples dispositivos
Si hay muchos dispositivos listados en `adb devices`, será necesario especificar el _número de serie_:
```bash
scrcpy --serial 0123456789abcdef
scrcpy -s 0123456789abcdef # versión breve
```
Si el dispositivo está conectado por TCP/IP:
```bash
scrcpy --serial 192.168.0.1:5555
scrcpy -s 192.168.0.1:5555 # versión breve
```
Puedes iniciar múltiples instancias de _scrcpy_ para múltiples dispositivos.
#### Autoiniciar al detectar dispositivo
Puedes utilizar [AutoAdb]:
```bash
autoadb scrcpy -s '{}'
```
[AutoAdb]: https://github.com/rom1v/autoadb
#### Túnel SSH
Para conectarse a un dispositivo remoto, es posible conectar un cliente local de `adb` a un servidor remoto `adb` (siempre y cuando utilicen la misma versión de protocolos _adb_):
```bash
adb kill-server # cierra el servidor local adb en 5037
ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
# conserva este servidor abierto
```
Desde otra terminal:
```bash
scrcpy
```
Para evitar habilitar "remote port forwarding", puedes forzar una "forward connection" (nótese el argumento `-L` en vez de `-R`):
```bash
adb kill-server # cierra el servidor local adb en 5037
ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 your_remote_computer
# conserva este servidor abierto
```
Desde otra terminal:
```bash
scrcpy --force-adb-forward
```
Al igual que las conexiones inalámbricas, puede resultar útil reducir la calidad:
```
scrcpy -b2M -m800 --max-fps 15
```
### Configuración de la ventana
#### Título
Por defecto, el título de la ventana es el modelo del dispositivo. Puede ser modificado:
```bash
scrcpy --window-title 'My device'
```
#### Posición y tamaño
La posición y tamaño inicial de la ventana puede ser especificado:
```bash
scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
```
#### Sin bordes
Para deshabilitar el diseño de la ventana:
```bash
scrcpy --window-borderless
```
#### Siempre adelante
Para mantener la ventana de scrcpy siempre adelante:
```bash
scrcpy --always-on-top
```
#### Pantalla completa
La aplicación puede ser iniciada en pantalla completa:
```bash
scrcpy --fullscreen
scrcpy -f # versión breve
```
Puede entrar y salir de la pantalla completa con la combinación <kbd>MOD</kbd>+<kbd>f</kbd>.
#### Rotación
Se puede rotar la ventana:
```bash
scrcpy --rotation 1
```
Los valores posibles son:
- `0`: sin rotación
- `1`: 90 grados contrarreloj
- `2`: 180 grados
- `3`: 90 grados en sentido de las agujas del reloj
La rotación también puede ser modificada con la combinación de teclas <kbd>MOD</kbd>+<kbd>←</kbd> _(izquierda)_ y <kbd>MOD</kbd>+<kbd>→</kbd> _(derecha)_.
Nótese que _scrcpy_ maneja 3 diferentes rotaciones:
- <kbd>MOD</kbd>+<kbd>r</kbd> solicita al dispositivo cambiar entre vertical y horizontal (la aplicación en uso puede rechazarlo si no soporta la orientación solicitada).
- [`--lock-video-orientation`](#fijar-la-rotación-del-video) cambia la rotación de la transmisión (la orientación del video enviado a la PC). Esto afecta a la grabación.
- `--rotation` (o <kbd>MOD</kbd>+<kbd>←</kbd>/<kbd>MOD</kbd>+<kbd>→</kbd>) rota solo el contenido de la imagen. Esto solo afecta a la imagen mostrada, no a la grabación.
### Otras opciones menores
#### Solo lectura ("Read-only")
Para deshabilitar los controles (todo lo que interactúe con el dispositivo: eventos del teclado, eventos del mouse, arrastrar y soltar archivos):
```bash
scrcpy --no-control
scrcpy -n # versión breve
```
#### Pantalla
Si múltiples pantallas están disponibles, es posible elegir cual transmitir:
```bash
scrcpy --display 1
```
Los ids de las pantallas se pueden obtener con el siguiente comando:
```bash
adb shell dumpsys display # busque "mDisplayId=" en la respuesta
```
La segunda pantalla solo puede ser manejada si el dispositivo cuenta con Android 10 (en caso contrario será transmitida en el modo solo lectura).
#### Permanecer activo
Para evitar que el dispositivo descanse después de un tiempo mientras está conectado:
```bash
scrcpy --stay-awake
scrcpy -w # versión breve
```
La configuración original se restaura al cerrar scrcpy.
#### Apagar la pantalla
Es posible apagar la pantalla mientras se transmite al iniciar con el siguiente comando:
```bash
scrcpy --turn-screen-off
scrcpy -S # versión breve
```
O presionando <kbd>MOD</kbd>+<kbd>o</kbd> en cualquier momento.
Para volver a prenderla, presione <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd>.
En Android, el botón de `POWER` siempre prende la pantalla. Por conveniencia, si `POWER` es enviado vía scrcpy (con click-derecho o <kbd>MOD</kbd>+<kbd>p</kbd>), esto forzará a apagar la pantalla con un poco de atraso (en la mejor de las situaciones). El botón físico `POWER` seguirá prendiendo la pantalla.
También puede resultar útil para evitar que el dispositivo entre en inactividad:
```bash
scrcpy --turn-screen-off --stay-awake
scrcpy -Sw # versión breve
```
#### Renderizar frames vencidos
Por defecto, para minimizar la latencia, _scrcpy_ siempre renderiza el último frame disponible decodificado, e ignora cualquier frame anterior.
Para forzar el renderizado de todos los frames (a costo de posible aumento de latencia), use:
```bash
scrcpy --render-expired-frames
```
#### Mostrar clicks
Para presentaciones, puede resultar útil mostrar los clicks físicos (en el dispositivo físicamente).
Android provee esta opción en _Opciones para desarrolladores_.
_Scrcpy_ provee una opción para habilitar esta función al iniciar la aplicación y restaurar el valor original al salir:
```bash
scrcpy --show-touches
scrcpy -t # versión breve
```
Nótese que solo muestra los clicks _físicos_ (con el dedo en el dispositivo).
#### Desactivar protector de pantalla
Por defecto, scrcpy no evita que el protector de pantalla se active en la computadora.
Para deshabilitarlo:
```bash
scrcpy --disable-screensaver
```
### Control
#### Rotar pantalla del dispositivo
Presione <kbd>MOD</kbd>+<kbd>r</kbd> para cambiar entre posición vertical y horizontal.
Nótese que solo rotará si la aplicación activa soporta la orientación solicitada.
#### Copiar y pegar
Cuando que el portapapeles de Android cambia, automáticamente se sincroniza al portapapeles de la computadora.
Cualquier shortcut con <kbd>Ctrl</kbd> es enviado al dispositivo. En particular:
- <kbd>Ctrl</kbd>+<kbd>c</kbd> normalmente copia
- <kbd>Ctrl</kbd>+<kbd>x</kbd> normalmente corta
- <kbd>Ctrl</kbd>+<kbd>v</kbd> normalmente pega (después de la sincronización de portapapeles entre la computadora y el dispositivo)
Esto normalmente funciona como es esperado.
Sin embargo, este comportamiento depende de la aplicación en uso. Por ejemplo, _Termux_ envía SIGINT con <kbd>Ctrl</kbd>+<kbd>c</kbd>, y _K-9 Mail_ crea un nuevo mensaje.
Para copiar, cortar y pegar, en tales casos (solo soportado en Android >= 7):
- <kbd>MOD</kbd>+<kbd>c</kbd> inyecta `COPY`
- <kbd>MOD</kbd>+<kbd>x</kbd> inyecta `CUT`
- <kbd>MOD</kbd>+<kbd>v</kbd> inyecta `PASTE` (después de la sincronización de portapapeles entre la computadora y el dispositivo)
Además, <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> permite inyectar el texto en el portapapeles de la computadora como una secuencia de teclas. Esto es útil cuando el componente no acepta pegado de texto (por ejemplo en _Termux_), pero puede romper caracteres no pertenecientes a ASCII.
**AVISO:** Pegar de la computadora al dispositivo (tanto con <kbd>Ctrl</kbd>+<kbd>v</kbd> o <kbd>MOD</kbd>+<kbd>v</kbd>) copia el contenido al portapapeles del dispositivo. Como consecuencia, cualquier aplicación de Android puede leer su contenido. Debería evitar pegar contenido sensible (como contraseñas) de esta forma.
Algunos dispositivos no se comportan como es esperado al establecer el portapapeles programáticamente. La opción `--legacy-paste` está disponible para cambiar el comportamiento de <kbd>Ctrl</kbd>+<kbd>v</kbd> y <kbd>MOD</kbd>+<kbd>v</kbd> para que también inyecten el texto del portapapeles de la computadora como una secuencia de teclas (de la misma forma que <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd>).
#### Pellizcar para zoom
Para simular "pinch-to-zoom": <kbd>Ctrl</kbd>+_click-y-mover_.
Más precisamente, mantén <kbd>Ctrl</kbd> mientras presionas botón izquierdo. Hasta que no se suelte el botón, todos los movimientos del mouse cambiarán el tamaño y rotación del contenido (si es soportado por la app en uso) respecto al centro de la pantalla.
Concretamente, scrcpy genera clicks adicionales con un "dedo virtual" en la posición invertida respecto al centro de la pantalla.
#### Preferencias de inyección de texto
Existen dos tipos de [eventos][textevents] generados al escribir texto:
- _key events_, marcando si la tecla es presionada o soltada;
- _text events_, marcando si un texto fue introducido.
Por defecto, las letras son inyectadas usando _key events_, para que el teclado funcione como es esperado en juegos (típicamente las teclas WASD).
Pero esto puede [causar problemas][prefertext]. Si encuentras tales problemas, los puedes evitar con:
```bash
scrcpy --prefer-text
```
(Pero esto romperá el comportamiento del teclado en los juegos)
[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
#### Repetir tecla
Por defecto, mantener una tecla presionada genera múltiples _key events_. Esto puede causar problemas de desempeño en algunos juegos, donde estos eventos no tienen sentido de todos modos.
Para evitar enviar _key events_ repetidos:
```bash
scrcpy --no-key-repeat
```
#### Botón derecho y botón del medio
Por defecto, botón derecho ejecuta RETROCEDER (o ENCENDIDO) y botón del medio INICIO. Para inhabilitar estos atajos y enviar los clicks al dispositivo:
```bash
scrcpy --forward-all-clicks
```
### Arrastrar y soltar archivos
#### Instalar APKs
Para instalar un APK, arrastre y suelte el archivo APK (terminado en `.apk`) a la ventana de _scrcpy_.
No hay respuesta visual, un mensaje se escribirá en la consola.
#### Enviar archivos al dispositivo
Para enviar un archivo a `/sdcard/` en el dispositivo, arrastre y suelte un archivo (no APK) a la ventana de _scrcpy_.
No hay respuesta visual, un mensaje se escribirá en la consola.
El directorio de destino puede ser modificado al iniciar:
```bash
scrcpy --push-target=/sdcard/Download/
```
### Envío de Audio
_Scrcpy_ no envía el audio. Use [sndcpy].
También lea [issue #14].
[sndcpy]: https://github.com/rom1v/sndcpy
[issue #14]: https://github.com/Genymobile/scrcpy/issues/14
## Atajos
En la siguiente lista, <kbd>MOD</kbd> es el atajo modificador. Por defecto es <kbd>Alt</kbd> (izquierdo) o <kbd>Super</kbd> (izquierdo).
Se puede modificar usando `--shortcut-mod`. Las posibles teclas son `lctrl` (izquierdo), `rctrl` (derecho), `lalt` (izquierdo), `ralt` (derecho), `lsuper` (izquierdo) y `rsuper` (derecho). Por ejemplo:
```bash
# use RCtrl para los atajos
scrcpy --shortcut-mod=rctrl
# use tanto LCtrl+LAlt o LSuper para los atajos
scrcpy --shortcut-mod=lctrl+lalt,lsuper
```
_<kbd>[Super]</kbd> es generalmente la tecla <kbd>Windows</kbd> o <kbd>Cmd</kbd>._
[Super]: https://en.wikipedia.org/wiki/Super_key_(keyboard_button)

Todos los atajos <kbd>Ctrl</kbd>+_tecla_ son enviados al dispositivo para que sean manejados por la aplicación activa.
## Path personalizado
Para usar un binario de _adb_ en particular, configure el path `ADB` en las variables de entorno:
```bash
ADB=/path/to/adb scrcpy
```
Para sobreescribir el path del archivo `scrcpy-server`, configure el path en `SCRCPY_SERVER_PATH`.
## ¿Por qué _scrcpy_?
Un colega me retó a encontrar un nombre tan impronunciable como [gnirehtet].
[`strcpy`] copia un **str**ing; `scrcpy` copia un **scr**een.
[gnirehtet]: https://github.com/Genymobile/gnirehtet

## Çalıştırma
Android cihazınızı bağlayın ve aşağıdaki komutu çalıştırın:
```bash
scrcpy
```
Komut satırı argümanları aşağıdaki komut ile listelenebilir:
```bash
scrcpy --help
```
## Özellikler
### Ekran yakalama ayarları
#### Boyut azaltma
Bazen, Android cihaz ekranını daha düşük seviyede göstermek performansı artırabilir.
Hem genişliği hem de yüksekliği bir değere sabitlemek için (ör. 1024):
```bash
scrcpy --max-size 1024
scrcpy -m 1024 # kısa versiyon
```
Diğer boyut en-boy oranı korunacak şekilde hesaplanır.
Bu şekilde ekran boyutu 1920x1080 olan bir cihaz 1024x576 olarak görünür.
#### Bit-oranı değiştirme
Varsayılan bit-oranı 8 Mbps'dir. Değiştirmek için (ör. 2 Mbps):
```bash
scrcpy --bit-rate 2M
scrcpy -b 2M # kısa versiyon
```
#### Çerçeve oranı sınırlama
Ekran yakalama için maksimum çerçeve oranı için sınır koyulabilir:
```bash
scrcpy --max-fps 15
```
Bu özellik Android 10 ve sonrası sürümlerde resmi olarak desteklenmektedir,
ancak daha önceki sürümlerde çalışmayabilir.
#### Kesme
Cihaz ekranının sadece bir kısmı görünecek şekilde kesilebilir.
Bu özellik Oculus Go'nun bir gözünü yakalamak gibi durumlarda kullanışlı olur:
```bash
scrcpy --crop 1224:1440:0:0 # (0,0) noktasından 1224x1440
```
Eğer `--max-size` belirtilmişse yeniden boyutlandırma kesme işleminden sonra yapılır.
#### Video yönünü kilitleme
Videonun yönünü kilitlemek için:
```bash
scrcpy --lock-video-orientation # başlangıç yönü
scrcpy --lock-video-orientation=0 # doğal yön
scrcpy --lock-video-orientation=1 # 90° saatin tersi yönü
scrcpy --lock-video-orientation=2 # 180°
scrcpy --lock-video-orientation=3 # 90° saat yönü
```
Bu özellik kaydetme yönünü de etkiler.
[Pencere ayrı olarak döndürülmüş](#rotation) olabilir.
#### Kodlayıcı
Bazı cihazlar birden fazla kodlayıcıya sahiptir, ve bunların bazıları programın
kapanmasına sebep olabilir. Bu durumda farklı bir kodlayıcı seçilebilir:
```bash
scrcpy --encoder OMX.qcom.video.encoder.avc
```
Mevcut kodlayıcıları listelemek için geçerli olmayan bir kodlayıcı ismi girebilirsiniz,
hata mesajı mevcut kodlayıcıları listeleyecektir:
```bash
scrcpy --encoder _
```
### Yakalama
#### Kaydetme
Ekran yakalama sırasında kaydedilebilir:
```bash
scrcpy --record file.mp4
scrcpy -r file.mkv
```
Yakalama olmadan kayıt için:
```bash
scrcpy --no-display --record file.mp4
scrcpy -Nr file.mkv
# Ctrl+C ile kayıt kesilebilir
```
"Atlanan kareler" gerçek zamanlı olarak gösterilmese (performans sebeplerinden ötürü) dahi kaydedilir.
Kareler cihazda _zamandamgası_ ile saklanır, bu sayede [paket gecikme varyasyonu]
kayıt edilen dosyayı etkilemez.
[paket gecikme varyasyonu]: https://en.wikipedia.org/wiki/Packet_delay_variation
#### v4l2loopback
Linux'ta video akışı bir v4l2 loopback cihazına gönderilebilir. Bu sayede Android
cihaz bir web kamerası gibi davranabilir.
Bu işlem için `v4l2loopback` modülü kurulu olmalıdır:
```bash
sudo apt install v4l2loopback-dkms
```
v4l2 cihazı oluşturmak için:
```bash
sudo modprobe v4l2loopback
```
Bu komut `/dev/videoN` adresinde `N` yerine bir tamsayı koyarak yeni bir video
cihazı oluşturacaktır.
(birden fazla cihaz oluşturmak veya spesifik ID'ye sahip cihazlar için
diğer [seçenekleri](https://github.com/umlaeute/v4l2loopback#options) inceleyebilirsiniz.)
Aktif cihazları listelemek için:
```bash
# v4l-utils paketi ile
v4l2-ctl --list-devices
# daha basit ama yeterli olabilecek şekilde
ls /dev/video*
```
v4l2 kullanarak scrpy kullanmaya başlamak için:
```bash
scrcpy --v4l2-sink=/dev/videoN
scrcpy --v4l2-sink=/dev/videoN --no-display # ayna penceresini kapatarak
scrcpy --v4l2-sink=/dev/videoN -N # kısa versiyon
```
(`N` harfini oluşturulan cihaz ID numarası ile değiştirin. `ls /dev/video*` cihaz ID'lerini görebilirsiniz.)
Aktifleştirildikten sonra video akışını herhangi bir v4l2 özellikli araçla açabilirsiniz:
```bash
ffplay -i /dev/videoN
vlc v4l2:///dev/videoN # VLC kullanırken yükleme gecikmesi olabilir
```
Örneğin, [OBS] ile video akışını kullanabilirsiniz.
[obs]: https://obsproject.com/
### Bağlantı
#### Kablosuz
_Scrcpy_ cihazla iletişim kurmak için `adb`'yi kullanır, Ve `adb`
bir cihaza TCP/IP kullanarak [bağlanabilir].
1. Cihazınızı bilgisayarınızla aynı Wi-Fi ağına bağlayın.
2. Cihazınızın IP adresini bulun. Ayarlar → Telefon Hakkında → Durum sekmesinden veya
aşağıdaki komutu çalıştırarak öğrenebilirsiniz:
```bash
adb shell ip route | awk '{print $9}'
```
3. Cihazınızda TCP/IP üzerinden adb kullanımını etkinleştirin: `adb tcpip 5555`.
4. Cihazınızı bilgisayarınızdan sökün.
5. Cihazınıza bağlanın: `adb connect DEVICE_IP:5555` _(`DEVICE_IP` değerini değiştirin)_.
6. `scrcpy` komutunu normal olarak çalıştırın.
Bit-oranını ve büyüklüğü azaltmak yararlı olabilir:
```bash
scrcpy --bit-rate 2M --max-size 800
scrcpy -b2M -m800 # kısa version
```
[bağlanabilir]: https://developer.android.com/studio/command-line/adb.html#wireless
#### Birden fazla cihaz
Eğer `adb devices` komutu birden fazla cihaz listeliyorsa _serial_ değerini belirtmeniz gerekir:
```bash
scrcpy --serial 0123456789abcdef
scrcpy -s 0123456789abcdef # kısa versiyon
```
Eğer cihaz TCP/IP üzerinden bağlanmışsa:
```bash
scrcpy --serial 192.168.0.1:5555
scrcpy -s 192.168.0.1:5555 # kısa version
```
Birden fazla cihaz için birden fazla _scrcpy_ uygulaması çalıştırabilirsiniz.
#### Cihaz bağlantısı ile otomatik başlatma
[AutoAdb] ile yapılabilir:
```bash
autoadb scrcpy -s '{}'
```
[autoadb]: https://github.com/rom1v/autoadb
#### SSH Tünel
Uzaktaki bir cihaza erişmek için lokal `adb` istemcisi, uzaktaki bir `adb` sunucusuna
(aynı _adb_ sürümünü kullanmak şartı ile) bağlanabilir :
```bash
adb kill-server # 5037 portunda çalışan lokal adb sunucusunu kapat
ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
# bunu açık tutun
```
Başka bir terminalde:
```bash
scrcpy
```
Uzaktan port yönlendirme ileri yönlü bağlantı kullanabilirsiniz
(`-R` yerine `-L` olduğuna dikkat edin):
```bash
adb kill-server # 5037 portunda çalışan lokal adb sunucusunu kapat
ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 your_remote_computer
# bunu açık tutun
```
Başka bir terminalde:
```bash
scrcpy --force-adb-forward
```
Kablosuz bağlantı gibi burada da kalite düşürmek faydalı olabilir:
```
scrcpy -b2M -m800 --max-fps 15
```
### Pencere ayarları
#### İsim
Cihaz modeli varsayılan pencere ismidir. Değiştirmek için:
```bash
scrcpy --window-title 'Benim cihazım'
```
#### Konum ve
Pencerenin başlangıç konumu ve boyutu belirtilebilir:
```bash
scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
```
#### Kenarlıklar
Pencere dekorasyonunu kapatmak için:
```bash
scrcpy --window-borderless
```
#### Her zaman üstte
Scrcpy penceresini her zaman üstte tutmak için:
```bash
scrcpy --always-on-top
```
#### Tam ekran
Uygulamayı tam ekran başlatmak için:
```bash
scrcpy --fullscreen
scrcpy -f # kısa versiyon
```
Tam ekran <kbd>MOD</kbd>+<kbd>f</kbd> ile dinamik olarak değiştirilebilir.
#### Döndürme
Pencere döndürülebilir:
```bash
scrcpy --rotation 1
```
Seçilebilecek değerler:
- `0`: döndürme yok
- `1`: 90 derece saat yönünün tersi
- `2`: 180 derece
- `3`: 90 derece saat yönü
Döndürme <kbd>MOD</kbd>+<kbd>←</kbd>_(sol)_ ve
<kbd>MOD</kbd>+<kbd>→</kbd> _(sağ)_ ile dinamik olarak değiştirilebilir.
_scrcpy_'de 3 farklı döndürme olduğuna dikkat edin:
- <kbd>MOD</kbd>+<kbd>r</kbd> cihazın yatay veya dikey modda çalışmasını sağlar.
(çalışan uygulama istenilen oryantasyonda çalışmayı desteklemiyorsa döndürme
işlemini reddedebilir.)
- [`--lock-video-orientation`](#lock-video-orientation) görüntü yakalama oryantasyonunu
(cihazdan bilgisayara gelen video akışının oryantasyonu) değiştirir. Bu kayıt işlemini
etkiler.
- `--rotation` (or <kbd>MOD</kbd>+<kbd>←</kbd>/<kbd>MOD</kbd>+<kbd>→</kbd>)
pencere içeriğini dönderir. Bu sadece canlı görüntüyü etkiler, kayıt işlemini etkilemez.
### Diğer ekran yakalama seçenekleri
#### Yazma korumalı
Kontrolleri devre dışı bırakmak için (cihazla etkileşime geçebilecek her şey: klavye ve
fare girdileri, dosya sürükleyip bırakma):
```bash
scrcpy --no-control
scrcpy -n
```
#### Ekran
Eğer cihazın birden fazla ekranı varsa hangi ekranın kullanılacağını seçebilirsiniz:
```bash
scrcpy --display 1
```
Kullanılabilecek ekranları listelemek için:
```bash
adb shell dumpsys display # çıktı içerisinde "mDisplayId=" terimini arayın
```
İkinci ekran ancak cihaz Android sürümü 10 veya üzeri olmalıdır (değilse yazma korumalı
olarak görüntülenir).
#### Uyanık kalma
Cihazın uyku moduna girmesini engellemek için:
```bash
scrcpy --stay-awake
scrcpy -w
```
scrcpy kapandığında cihaz başlangıç durumuna geri döner.
#### Ekranı kapatma
Ekran yakalama sırasında cihazın ekranı kapatılabilir:
```bash
scrcpy --turn-screen-off
scrcpy -S
```
Ya da <kbd>MOD</kbd>+<kbd>o</kbd> kısayolunu kullanabilirsiniz.
Tekrar açmak için ise <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd> tuşlarına basın.
Android'de, `GÜÇ` tuşu her zaman ekranı açar. Eğer `GÜÇ` sinyali scrcpy ile
gönderilsiyse (sağ tık veya <kbd>MOD</kbd>+<kbd>p</kbd>), ekran kısa bir gecikme
ile kapanacaktır. Fiziksel `GÜÇ` tuşuna basmak hala ekranın açılmasına sebep olacaktır.
Bu cihazın uykuya geçmesini engellemek için kullanılabilir:
```bash
scrcpy --turn-screen-off --stay-awake
scrcpy -Sw
```
#### Dokunuşları gösterme
Sunumlar sırasında fiziksel dokunuşları (fiziksel cihazdaki) göstermek
faydalı olabilir.
Android'de bu özellik _Geliştici seçenekleri_ içerisinde bulunur.
_Scrcpy_ bu özelliği çalışırken etkinleştirebilir ve kapanırken eski
haline geri getirebilir:
```bash
scrcpy --show-touches
scrcpy -t
```
Bu opsiyon sadece _fiziksel_ dokunuşları (cihaz ekranındaki) gösterir.
#### Ekran koruyucuyu devre dışı bırakma
Scrcpy varsayılan ayarlarında ekran koruyucuyu devre dışı bırakmaz.
Bırakmak için:
```bash
scrcpy --disable-screensaver
```
### Girdi kontrolü
#### Cihaz ekranını dönderme
<kbd>MOD</kbd>+<kbd>r</kbd> tuşları ile yatay ve dikey modlar arasında
geçiş yapabilirsiniz.
Bu kısayol ancak çalışan uygulama desteklediği takdirde ekranı döndürecektir.
#### Kopyala yapıştır
Ne zaman Android cihazdaki pano değişse bilgisayardaki pano otomatik olarak
senkronize edilir.
Tüm <kbd>Ctrl</kbd> kısayolları cihaza iletilir:
- <kbd>Ctrl</kbd>+<kbd>c</kbd> genelde kopyalar
- <kbd>Ctrl</kbd>+<kbd>x</kbd> genelde keser
- <kbd>Ctrl</kbd>+<kbd>v</kbd> genelde yapıştırır (bilgisayar ve cihaz arasındaki
pano senkronizasyonundan sonra)
Bu kısayollar genelde beklediğiniz gibi çalışır.
Ancak kısayolun gerçekten yaptığı eylemi açık olan uygulama belirler.
Örneğin, _Termux_ <kbd>Ctrl</kbd>+<kbd>c</kbd> ile kopyalama yerine
SIGINT sinyali gönderir, _K-9 Mail_ ise yeni mesaj oluşturur.
Bu tip durumlarda kopyalama, kesme ve yapıştırma için (Android versiyon 7 ve
üstü):
- <kbd>MOD</kbd>+<kbd>c</kbd> `KOPYALA`
- <kbd>MOD</kbd>+<kbd>x</kbd> `KES`
- <kbd>MOD</kbd>+<kbd>v</kbd> `YAPIŞTIR` (bilgisayar ve cihaz arasındaki
pano senkronizasyonundan sonra)
Bunlara ek olarak, <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> tuşları
bilgisayar pano içeriğini tuş basma eylemleri şeklinde gönderir. Bu metin
yapıştırmayı desteklemeyen (_Termux_ gibi) uygulamar için kullanışlıdır,
ancak ASCII olmayan içerikleri bozabilir.
**UYARI:** Bilgisayar pano içeriğini cihaza yapıştırmak
(<kbd>Ctrl</kbd>+<kbd>v</kbd> ya da <kbd>MOD</kbd>+<kbd>v</kbd> tuşları ile)
içeriği cihaz panosuna kopyalar. Sonuç olarak, herhangi bir Android uygulaması
içeriğe erişebilir. Hassas içerikler (parolalar gibi) için bu özelliği kullanmaktan
kaçının.
Bazı cihazlar pano değişikleri konusunda beklenilen şekilde çalışmayabilir.
Bu durumlarda `--legacy-paste` argümanı kullanılabilir. Bu sayede
<kbd>Ctrl</kbd>+<kbd>v</kbd> ve <kbd>MOD</kbd>+<kbd>v</kbd> tuşları da
pano içeriğini tuş basma eylemleri şeklinde gönderir
(<kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> ile aynı şekilde).
#### İki parmak ile yakınlaştırma
"İki parmak ile yakınlaştırma" için: <kbd>Ctrl</kbd>+_tıkla-ve-sürükle_.
Daha açıklayıcı şekilde, <kbd>Ctrl</kbd> tuşuna sol-tık ile birlikte basılı
tutun. Sol-tık serbest bırakılıncaya kadar yapılan tüm fare hareketleri
ekran içeriğini ekranın merkezini baz alarak dönderir, büyütür veya küçültür
(eğer uygulama destekliyorsa).
Scrcpy ekranın merkezinde bir "sanal parmak" varmış gibi davranır.
#### Metin gönderme tercihi
Metin girilirken ili çeşit [eylem][textevents] gerçekleştirilir:
- _tuş eylemleri_, bir tuşa basıldığı sinyalini verir;
- _metin eylemleri_, bir metin girildiği sinyalini verir.
Varsayılan olarak, harfler tuş eylemleri kullanılarak gönderilir. Bu sayede
klavye oyunlarda beklenilene uygun olarak çalışır (Genelde WASD tuşları).
Ancak bu [bazı problemlere][prefertext] yol açabilir. Eğer bu problemler ile
karşılaşırsanız metin eylemlerini tercih edebilirsiniz:
```bash
scrcpy --prefer-text
```
(Ama bu oyunlardaki klavye davranışlarını bozacaktır)
[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
#### Tuş tekrarı
Varsayılan olarak, bir tuşa basılı tutmak tuş eylemini tekrarlar. Bu durum
bazı oyunlarda problemlere yol açabilir.
Tuş eylemlerinin tekrarını kapatmak için:
```bash
scrcpy --no-key-repeat
```
#### Sağ-tık ve Orta-tık
Varsayılan olarak, sağ-tık GERİ (ya da GÜÇ açma) eylemlerini, orta-tık ise
ANA EKRAN eylemini tetikler. Bu kısayolları devre dışı bırakmak için:
```bash
scrcpy --forward-all-clicks
```
### Dosya bırakma
#### APK kurulumu
APK kurmak için, bilgisayarınızdaki APK dosyasını (`.apk` ile biten) _scrcpy_
penceresine sürükleyip bırakın.
Bu eylem görsel bir geri dönüt oluşturmaz, konsola log yazılır.
#### Dosyayı cihaza gönderme
Bir dosyayı cihazdaki `/sdcard/Download/` dizinine atmak için, (APK olmayan)
bir dosyayı _scrcpy_ penceresine sürükleyip bırakın.
Bu eylem görsel bir geri dönüt oluşturmaz, konsola log yazılır.
Hedef dizin uygulama başlatılırken değiştirilebilir:
```bash
scrcpy --push-target=/sdcard/Movies/
```
### Ses iletimi
_Scrcpy_ ses iletimi yapmaz. Yerine [sndcpy] kullanabilirsiniz.

## Kısayollar
Aşağıdaki listede, <kbd>MOD</kbd> kısayol tamamlayıcısıdır. Varsayılan olarak
(sol) <kbd>Alt</kbd> veya (sol) <kbd>Super</kbd> tuşudur.
Bu tuş `--shortcut-mod` argümanı kullanılarak `lctrl`, `rctrl`,
`lalt`, `ralt`, `lsuper` ve `rsuper` tuşlarından biri ile değiştirilebilir.
Örneğin:
```bash
# Sağ Ctrl kullanmak için
scrcpy --shortcut-mod=rctrl
# Sol Ctrl, Sol Alt veya Sol Super tuşlarından birini kullanmak için
scrcpy --shortcut-mod=lctrl+lalt,lsuper
```
_<kbd>[Super]</kbd> tuşu genelde <kbd>Windows</kbd> veya <kbd>Cmd</kbd> tuşudur._

_²Sağ-tık ekran kapalıysa açar, değilse GERİ sinyali gönderir._
_³4. ve 5. fare tuşları (eğer varsa)._
_⁴Sadece Android 7 ve üzeri versiyonlarda._
Tekrarlı tuşu olan kısayollar tuş bırakılıp tekrar basılarak tekrar çalıştırılır.
Örneğin, "Ayarlar panelini genişletmek" için:
1. <kbd>MOD</kbd> tuşuna basın ve basılı tutun.
2. <kbd>n</kbd> tuşuna iki defa basın.
3. <kbd>MOD</kbd> tuşuna basmayı bırakın.
Tüm <kbd>Ctrl</kbd>+_tuş_ kısayolları cihaza gönderilir. Bu sayede istenilen komut
uygulama tarafından çalıştırılır.
## Özel dizinler
Varsayılandan farklı bir _adb_ programı çalıştırmak için `ADB` ortam değişkenini
ayarlayın:
```bash
ADB=/path/to/adb scrcpy

## 功能介绍
### 捕获设置
### 画面设置
#### 降低分辨率
#### 缩小分辨率
有时候,可以通过降低镜像分辨率来提高性能。
有时候,将设备屏幕镜像分辨率降低可以有效地提升性能。
要同时限制宽度和高度到某个值 (例如 1024)
我们可以将高度和宽度都限制在一定大小内(如 1024
```bash
scrcpy --max-size 1024
scrcpy -m 1024 # 简写
scrcpy -m 1024 # short version
```
一边会被按比例缩小以保持设备的显示比例。这样1920×1080 分辨率的设备会以 1024×576 的分辨率进行镜像。
较短的一边会被按比例缩小以保持设备的显示比例。
这样1920x1080 的设备会以 1024x576 的分辨率显示。
#### 修改
#### 修改画面比特
默认率是 8Mbps。要改变视频的码率 (例如改为 2Mbps)
默认的比特率是8Mbps。如果要改变画面的比特率 (比如说改成2Mbps)
```bash
scrcpy --bit-rate 2M
scrcpy -b 2M # 简写
scrcpy -b 2M # short version
```
#### 限制帧率
#### 限制画面帧率
要限制捕获的帧率
画面的帧率可以通过下面的命令被限制
```bash
scrcpy --max-fps 15
```
本功能从 Android 10 开始才被官方支持,但在一些旧版本中也能生效
这个功能仅在Android 10和以后的版本被Android官方支持但也有可能在更早的版本可用
#### 画面裁剪
可以对设备屏幕进行裁剪,只镜像屏幕的一部分
设备画面可在裁切后进行镜像,以显示部分屏幕
例如可以只镜像 Oculus Go 的一只眼睛。
这项功能可以用于,例如,只显示Oculus Go的一只眼睛。
```bash
scrcpy --crop 1224:1440:0:0 # 以 (0,0) 为原点的 1224x1440 像素
scrcpy --crop 1224:1440:0:0 # 1224x1440 at offset (0,0)
```
如果同时指定了 `--max-size`,会先进行裁剪,再进行缩放
如果`--max-size`在同时被指定,分辨率的改变将在画面裁切后进行
#### 锁定屏幕
#### 锁定屏幕
要锁定镜像画面的方向:
可以使用如下命令锁定屏幕朝向:
```bash
scrcpy --lock-video-orientation 0 # 自然
scrcpy --lock-video-orientation 1 # 逆时针旋转 90°
scrcpy --lock-video-orientation 0 # 自然
scrcpy --lock-video-orientation 1 # 90° 逆时针旋转
scrcpy --lock-video-orientation 2 # 180°
scrcpy --lock-video-orientation 3 # 顺时针旋转 90°
scrcpy --lock-video-orientation 3 # 90° 顺时针旋转
```
影响录制的方向
该设定影响录制。
[窗口可以独立旋转](#旋转)。
#### 编码器
一些设备内置了多种编码器,但是有的编码器会导致问题或崩溃。可以手动选择其它编码器:
```bash
scrcpy --encoder OMX.qcom.video.encoder.avc
```
要列出可用的编码器,可以指定一个不存在的编码器名称,错误信息中会包含所有的编码器:
```bash
scrcpy --encoder _
```
### 屏幕录制
可以在镜像的同时录制视频:
可以在屏幕镜像的同时录制视频:
```bash
scrcpy --record file.mp4
scrcpy -r file.mkv
```
仅录制,不显示镜像
在不开启屏幕镜像的同时录制
```bash
scrcpy --no-display --record file.mp4
scrcpy -Nr file.mkv
# 按 Ctrl+C 停止录制
# 按Ctrl+C停止录制
```
录制时会包含“被跳过的帧”,即使它们由于性能原因没有实时显示。设备会为每一帧打上 _时间戳_ ,所以 [包时延抖动][packet delay variation] 不会影响录制的文件。
在显示中“被跳过的帧”会被录制,虽然它们由于性能原因没有实时显示。
在传输中每一帧都有 _时间戳_ ,所以 [包时延变化] 并不影响录制的文件。

### 连接
### 连接方式
#### 无线
_Scrcpy_ 使用 `adb` 与设备通信,并且 `adb` 支持通过 TCP/IP [连接]到设备:
_Scrcpy_ 使用`adb`来与安卓设备连接。同时,`adb`能够通过TCP/IP[连接]到安卓设备:
1. 将设备和电脑连接至同一 Wi-Fi。
2. 打开 设置 → 关于手机状态信息,获取设备的 IP 地址,也可以执行以下的命令:
```bash
adb shell ip route | awk '{print $9}'
```
1.您的安卓设备和电脑连接至同一Wi-Fi。
2. 获取安卓设备的IP地址在设置-关于手机-状态信息)。
3. 打开安卓设备的网络adb功能`adb tcpip 5555`
4. 将您的设备与电脑断开连接。
5. 连接到您的设备:`adb connect DEVICE_IP:5555` _(用设备IP替换 `DEVICE_IP`)_.
6. 运行`scrcpy`
3. 启用设备的网络 adb 功能 `adb tcpip 5555`。
4. 断开设备的 USB 连接。
5. 连接到您的设备:`adb connect DEVICE_IP:5555` _(将 `DEVICE_IP` 替换为设备 IP)_.
6. 正常运行 `scrcpy`。
可能需要降低码率和分辨率:
降低比特率和分辨率可能有助于性能:

#### 复制
#### 复制
每次安卓的剪贴板变化时,其内容都会被自动同步到电脑的剪贴板上。
每次Android的剪贴板变化的时候,它都会被自动同步到电脑的剪贴板上。
所有的 <kbd>Ctrl</kbd> 快捷键都会被转发至设备。其中:
- <kbd>Ctrl</kbd>+<kbd>c</kbd> 通常执行复制
- <kbd>Ctrl</kbd>+<kbd>x</kbd> 通常执行剪切
- <kbd>Ctrl</kbd>+<kbd>v</kbd> 通常执行粘(在电脑到设备的剪贴板同步完成之后)
- <kbd>Ctrl</kbd>+<kbd>c</kbd> 复制
- <kbd>Ctrl</kbd>+<kbd>x</kbd> 剪切
- <kbd>Ctrl</kbd>+<kbd>v</kbd>在电脑到设备的剪贴板同步完成之后
大多数时候这些按键都会执行以上的功能
这通常如您所期望的那样运作
但实际的行为取决于设备上的前台程序。例如_Termux_ 会在按下 <kbd>Ctrl</kbd>+<kbd>c</kbd> 时发送 SIGINT又如 _K-9 Mail_ 会新建一封邮件。
但实际的行为取决于设备上的前台程序。
例如 _Termux_<kbd>Ctrl</kbd>+<kbd>c</kbd>被按下时发送 SIGINT
又如 _K-9 Mail_ 会新建一封新邮件。
在这种情况下进行剪切复制和粘贴 (仅支持 Android >= 7)
- <kbd>MOD</kbd>+<kbd>c</kbd> 注入 `COPY` (复制)
- <kbd>MOD</kbd>+<kbd>x</kbd> 注入 `CUT` (剪切)
- <kbd>MOD</kbd>+<kbd>v</kbd> 注入 `PASTE` (粘贴) (在电脑到设备的剪贴板同步完成之后)

- <kbd>MOD</kbd>+<kbd>v</kbd> 注入 `PASTE`(黏贴)(在电脑到设备的剪贴板同步完成之后
另外,<kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> 会将电脑的剪贴板内容转换为一串按键事件输入到设备。在应用程序不接受粘贴时 (比如 _Termux_),这项功能可以派上一定的用场。不过这项功能可能会导致非 ASCII 编码的内容出现错误

在应用程序不接受黏贴时(比如 _Termux_ ),这项功能可以排上一定的用场。
需要注意的是这项功能可能会导致非ASCII编码的内容出现错误。
**警告:** 将电脑剪贴板的内容贴至设备 (无论是通过 <kbd>Ctrl</kbd>+<kbd>v</kbd> 还是 <kbd>MOD</kbd>+<kbd>v</kbd>) 都会将内容复制到设备的剪贴板。如此,任何安卓应用程序都能读取到。您应避免将敏感内容 (如密码) 通过这种方式粘贴。
**警告:** 将电脑剪贴板的内容贴至设备无论是通过<kbd>Ctrl</kbd>+<kbd>v</kbd>还是<kbd>MOD</kbd>+<kbd>v</kbd>

您应当避免将敏感内容通过这种方式传输(如密码)。
一些设备不支持通过程序设置剪贴板。通过 `--legacy-paste` 选项可以修改 <kbd>Ctrl</kbd>+<kbd>v</kbd> 和 <kbd>MOD</kbd>+<kbd>v</kbd> 的工作方式,使它们通过按键事件 (同 <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd>) 来注入电脑剪贴板内容。
