-_Scrcpy_ usa `adb` per comunicare col dispositivo e `adb` può [connettersi][connect] a un dispositivo mediante TCP/IP. Il dispositivo deve essere collegato alla stessa rete del computer.

-##### Automatico
+_Scrcpy_ usa `adb` per comunicare col dispositivo e `adb` può [connettersi][connect] al dispositivo mediante TCP/IP:

-Un'opzione `--tcpip` permette di configurare automaticamente la connessione. Ci sono due varianti.
-
-Se il dispositivo (accessibile a 192.168.1.1 in questo esempio) ascolta già su una porta (tipicamente 5555) per le connessioni adb in entrata, allora esegui:
-
-```bash
-scrcpy --tcpip=192.168.1.1       # la porta predefinita è 5555
-scrcpy --tcpip=192.168.1.1:5555
-```
-
-Se la modalità TCP/IP di adb è disabilitata sul dispositivo (o se non si conosce l'indirizzo IP indirizzo), collegare il dispositivo tramite USB, quindi eseguire:
-
-```bash
-scrcpy --tcpip # senza argomenti
-```
-
-Il comando troverà automaticamente l'indirizzo IP del dispositivo, abiliterà la modalità TCP/IP, quindi connettersi al dispositivo prima di iniziare.
-
-##### Manuale
-
-In alternativa, è possibile abilitare la connessione TCP/IP manualmente usando `adb`:
-
-1. Inserisci il dispositivo in una porta USB del tuo computer.
-2. Connetti il dispositivo alla stessa rete Wi-Fi del tuo computer.
-3. Ottieni l'indirizzo IP del tuo dispositivo, in Impostazioni → Informazioni sul telefono → Stato, o
-   eseguendo questo comando:
+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}'
    ```

-4. Abilita adb via TCP/IP sul tuo dispositivo: `adb tcpip 5555`.
-5. Scollega il tuo dispositivo.
-6. Connettiti al tuo dispositivo: `adb connect DEVICE_IP:5555` _(sostituisci `DEVICE_IP`
-con l'indirizzo IP del dispositivo che hai trovato)_.
-7. Esegui `scrcpy` come al solito.
+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.

-Da Android 11, una [opzione di debug wireless][adb-wireless] permette di evitare di dover collegare fisicamente il dispositivo direttamente al computer.
-
-[adb-wireless]: https://developer.android.com/studio/command-line/adb#connect-to-a-device-over-wi-fi-android-11+
-
-Se la connessione cade casualmente, esegui il comando `scrcpy` per riconnetterti. Se il comando dice che non ci sono dispositivi/emulatori trovati, prova ad eseguire `adb connect DEVICE_IP:5555` di nuovo, e poi `scrcpy` come al solito. Se dice ancora che non ne ha trovato nessuno, prova ad eseguire `adb disconnect` e poi esegui di nuovo questi due comandi.

-
-Per impostazione predefinita, scrcpy utilizza la porta locale utilizzata per il tunnel `adb forward` (tipicamente `27183`, vedi `--port`). È anche possibile forzare una diversa porta del tunnel (può essere utile in situazioni più complesse, quando sono coinvolti più reindirizzamenti):
-
-```
-scrcpy --tunnel-port=1234
-```
-
-##### SSH tunnel
-
-Per comunicare con un server ADB remoto in modo sicuro, è preferibile utilizzare un tunnel SSH.
-
-Per prima cosa, assicurati che il server ADB sia in esecuzione sul computer remoto:
-
-```bash
-adb start-server
-```
-
-Poi, crea un tunnel SSH:
-
-```bash
-# local  5038 --> remote  5037
-# local 27183 <-- remote 27183
-ssh -CN -L5038:localhost:5037 -R27183:localhost:27183 your_remote_computer
-# keep this open
-```
-
-Da un altro terminale, esegui scrcpy:
-
-```bash
-export ADB_SERVER_SOCKET=tcp:localhost:5038
 scrcpy
 ```

 Per evitare l'abilitazione dell'apertura porte remota potresti invece forzare una "forward connection" (notare il `-L` invece di `-R`)

 ```bash
-# local  5038 --> remote  5037
-# local 27183 --> remote 27183
-ssh -CN -L5038:localhost:5037 -L27183:localhost:27183 your_remote_computer
+adb kill-server    # termina il server adb locale su 5037

-Concretamente, scrcpy genera degli eventi di tocco addizionali di un "dito virtuale" nella posizione simmetricamente opposta rispetto al centro dello schermo.
-
-#### Simulazione della tastiera fisica (HID)
-
-Per impostazione predefinita, scrcpy utilizza l'invio dei tasti o del testo di Android: funziona ovunque, ma è limitato all'ASCII.
-
-In alternativa scrcpy può simulare una tastiera fisica USB su Android per fornire una migliore esperienza di input (utilizzando [USB HID over AOAv2][hid-aoav2]): la tastiera virtuale è disabilitata e funziona per tutti i caratteri e IME.
-
-[hid-aoav2]: https://source.android.com/devices/accessories/aoa2#hid-support

-Tuttavia, funziona solo se il dispositivo è collegato via USB.
-
-Nota: su Windows, può funzionare solo in [odalità OTG](#otg), non durante il mirroring (non è possibile aprire un dispositivo USB se è già aperto da un altro processo come il daemon adb).

-Per abilitare questa modalità:
-
-```bash
-scrcpy --hid-keyboard
-scrcpy -K # versione breve
-```
-
-Se fallisce per qualche motivo (per esempio perché il dispositivo non è connesso via USB), ritorna automaticamente alla modalità predefinita (con un log nella console). Questo permette di usare le stesse opzioni della linea di comando quando si è connessi via USB e TCP/IP.
-
-In questa modalità, gli eventi i pressione originali (scancodes) sono inviati al dispositivo, indipendentemente dalla mappatura dei tasti dell'host.

-#### Simulazione del mouse fisico (HID)
-
-In modo simile alla simulazione della tastiera fisica, è possibile simulare un mouse fisico. Allo stesso modo funziona solo se il dispositivo è connesso via USB.
-
-Per impostazione predefinita, scrcpy utilizza l'invio degli eventi del mouse di Android, utilizzando coordinate assolute. Simulando un mouse fisico, un puntatore del mouse appare sul dispositivo Android e vengono inviati i movimenti relativi del mouse, i click e gli scorrimenti.

-I tasti speciali di cattura, <kbd>Alt</kbd> o <kbd>Super</kbd>, commutano (disabilitano o abilitano) la cattura del mouse. Usa uno di essi per ridare il controllo del mouse al computer.
-
-
-#### OTG
-
-È possibile eseguire _scrcpy_ con la sola simulazione della tastiera fisica e del mouse (HID), come se la tastiera e il mouse del computer fossero collegati direttamente al dispositivo tramite un cavo OTG.
-
-In questa modalità, _adb_ (debug USB) non è necessario e il mirroring è disabilitato.
-
-Per attivare la modallità OTG:
-
-```bash
-scrcpy --otg
-# Passa la seriale se sono disponibili diversi dispositivi USB
-scrcpy --otg -s 0123456789abcdef

-scrcpy --otg --hid-keyboard # solo la tastiera
-scrcpy --otg --hid-mouse # solo mouse
-scrcpy --otg --hid-keyboard --hid-mouse # tastiera e mouse
-# per comodità, abilita entrambi per default

-#### v4l2loopback
-
-En Linux se puede mandar el stream del video a un dispositivo loopback v4l2, por
-lo que se puede abrir el dispositivo Android como una webcam con cualquier
-programa compatible con v4l2.
-
-Se debe instalar el modulo `v4l2loopback`:
-
-```bash
-sudo apt install v4l2loopback-dkms
-```
-
-Para crear un dispositivo v4l2:
-
-```bash
-sudo modprobe v4l2loopback
-```
-
-Esto va a crear un nuevo dispositivo de video en `/dev/videoN`, donde `N` es un número
-(hay más [opciones](https://github.com/umlaeute/v4l2loopback#options) disponibles
-para crear múltiples dispositivos o usar un ID en específico).
-
-Para ver los dispositivos disponibles:
-
-```bash
-# requiere el paquete v4l-utils
-v4l2-ctl --list-devices
-# simple pero generalmente suficiente
-ls /dev/video*
-```
-
-Para iniciar scrcpy usando una fuente v4l2:
-
-```bash
-scrcpy --v4l2-sink=/dev/videoN
-scrcpy --v4l2-sink=/dev/videoN --no-display  # deshabilita la transmisión de imagen
-scrcpy --v4l2-sink=/dev/videoN -N            # más corto
-```
-
-(reemplace `N` con el ID del dispositivo, compruebe con `ls /dev/video*`)
-
-Una vez habilitado, podés abrir el stream del video con una herramienta compatible con v4l2:
-
-```bash
-ffplay -i /dev/videoN
-vlc v4l2:///dev/videoN   # VLC puede agregar un delay por buffering
-```
-
-Por ejemplo, podrías capturar el video usando [OBS].
-
-[OBS]: https://obsproject.com/
-
-
-#### Buffering
-
-Es posible agregar buffering al video. Esto reduce el ruido en la imagen ("jitter")
-pero aumenta la latencia (vea [#2464]).
-
-[#2464]: https://github.com/Genymobile/scrcpy/issues/2464
-
-La opción de buffering está disponible para la transmisión de imagen:
-
-```bash
-scrcpy --display-buffer=50  # agrega 50 ms de buffering a la imagen
-```
-
-y las fuentes V4L2:
-
-```bash
-scrcpy --v4l2-buffer=500    # agrega 500 ms de buffering a la fuente v4l2
-```
-
-
 ### Conexión

-#### TCP/IP (Inalámbrica)
+#### Inalámbrica

-_Scrcpy_ usa `adb` para comunicarse con el dispositivo, y `adb` puede [conectarse] vía TCP/IP.
-El dispositivo debe estar conectado a la misma red que la computadora:
-
-##### Automático
-
-La opción `--tcpip` permite configurar la conexión automáticamente. Hay 2 variables.
-
-Si el dispositivo (accesible en 192.168.1.1 para este ejemplo) ya está escuchando
-en un puerto (generalmente 5555) esperando una conexión adb entrante, entonces corré:
-
-```bash
-scrcpy --tcpip=192.168.1.1       # el puerto default es 5555
-scrcpy --tcpip=192.168.1.1:5555
-```
-
-Si el dispositivo no tiene habilitado el modo adb TCP/IP (o si no sabés la dirección IP),
-entonces conectá el dispositivo por USB y corré:
-
-```bash
-scrcpy --tcpip    # sin argumentos
-```
-
-El programa buscará automáticamente la IP del dispositivo, habilitará el modo TCP/IP, y
-se conectará al dispositivo antes de comenzar a transmitir la imagen.
-
-##### Manual
-
-Como alternativa, se puede habilitar la conexión TCP/IP manualmente usando `adb`:

+Desde otra terminal:

 ```bash
-export ADB_SERVER_SOCKET=tcp:192.168.1.2:5037
-scrcpy --tunnel-host=192.168.1.2
-```
-
-Por default, scrcpy usa el puerto local que se usó para establecer el tunel
-`adb forward` (típicamente `27183`, vea `--port`). También es posible forzar un
-puerto diferente (puede resultar útil en situaciones más complejas, donde haya
-múltiples redirecciones):
-
-```
-scrcpy --tunnel-port=1234
-```
-
-
-##### Túnel SSH
-
-Para comunicarse con un servidor ADB remoto de forma segura, es preferible usar un túnel SSH.
-
-Primero, asegurate que el servidor ADB está corriendo en la computadora remota:
-
-```bash
-adb start-server
-```
-
-Después, establecé el túnel SSH:
-
-```bash
-# local  5038 --> remoto  5037
-# local 27183 <-- remoto 27183
-ssh -CN -L5038:localhost:5037 -R27183:localhost:27183 your_remote_computer
-# conserva este servidor abierto
-```
-
-Desde otra terminal, corré scrcpy:
-
-```bash
-export ADB_SERVER_SOCKET=tcp:localhost:5038
 scrcpy
 ```

 Para evitar habilitar "remote port forwarding", puedes forzar una "forward connection" (nótese el argumento `-L` en vez de `-R`):

 ```bash
-# local  5038 --> remoto  5037
-# local 27183 --> remoto 27183
-ssh -CN -L5038:localhost:5037 -L27183:localhost:27183 your_remote_computer
+adb kill-server    # cierra el servidor local adb en 5037
+ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 your_remote_computer

-#### Emular teclado físico (HID)
-
-Por default, scrcpy usa el sistema de Android para la injección de teclas o texto:
-funciona en todas partes, pero está limitado a ASCII.
-
-En Linux, scrcpy puede emular un teclado USB físico en Android para proveer
-una mejor experiencia al enviar _inputs_ (usando [USB HID vía AOAv2][hid-aoav2]):
-deshabilita el teclado virtual y funciona para todos los caracteres y IME.
-
-[hid-aoav2]: https://source.android.com/devices/accessories/aoa2#hid-support
-
-Sin embargo, solo funciona si el dispositivo está conectado por USB, y por ahora
-solo funciona en Linux.
-
-Para habilitar este modo:
-
-```bash
-scrcpy --hid-keyboard
-scrcpy -K  # más corto
-```
-
-Si por alguna razón falla (por ejemplo si el dispositivo no está conectado vía
-USB), automáticamente vuelve al modo default (un mensaje se escribirá en la consola).
-Se puede usar los mismos argumentos en la línea de comandos tanto si se conecta con
-USB o vía TCP/IP.
-
-En este modo, los _raw key events_ (_scancodes_) se envían al dispositivo, independientemente
-del mapeo del teclado en el host. Por eso, si el diseño de tu teclado no concuerda, debe ser
-configurado en el dispositivo Android, en Ajustes → Sistema → Idioma y Entrada de Texto
-→ [Teclado Físico].
-
-Se puede iniciar automáticamente en esta página de ajustes:
-
-```bash
-adb shell am start -a android.settings.HARD_KEYBOARD_SETTINGS
-```
-
-Sin embargo, la opción solo está disponible cuando el teclado HID está activo
-(o cuando se conecta un teclado físico).

-
-对于传入的 adb 连接，如果设备（在这个例子中以192.168.1.1为可用地址）已经监听了一个端口（通常是5555），运行：
-
-```bash
-scrcpy --tcpip=192.168.1.1       # 默认端口是5555
-scrcpy --tcpip=192.168.1.1:5555
-```
-
-如果adb TCP/IP（无线） 模式在某些设备上不被启用（或者你不知道IP地址），用USB连接设备，然后运行：
-
-```bash
-scrcpy --tcpip    # 无需其他参数
-```
-
-这将会自动寻找设备IP地址，启用TCP/IP模式，然后在启动之前连接到设备。
-
-##### 手动配置

-[实体键盘]: https://github.com/Genymobile/scrcpy/pull/2632#issuecomment-923756915
-
-#### 物理鼠标模拟 (HID)
-
-与物理键盘模拟类似，可以模拟一个物理鼠标。 同样，它仅在设备通过 USB 连接时才有效，并且目前仅在 Linux 上受支持。
-
-默认情况下，scrcpy 使用 Android 鼠标事件注入，使用绝对坐标。 通过模拟物理鼠标，在Android设备上出现鼠标指针，并注入鼠标相对运动、点击和滚动。
-
-启用此模式:
-
-```bash
-scrcpy --hid-mouse
-scrcpy -M  # 简写
-```
-
-您还可以将 `--forward-all-clicks` 添加到 [转发所有点击][forward_all_clicks].
-
-[forward_all_clicks]: #右键和中键
-
-启用此模式后，计算机鼠标将被“捕获”（鼠标指针从计算机上消失并出现在 Android 设备上）。
-
-特殊的捕获键，<kbd>Alt</kbd> 或 <kbd>Super</kbd>，切换（禁用或启用）鼠标捕获。 使用其中之一将鼠标的控制权交还给计算机。
-
-
-#### OTG
-
-可以仅使用物理键盘和鼠标模拟 (HID) 运行 _scrcpy_，就好像计算机键盘和鼠标通过 OTG 线直接插入设备一样。
-
-在这个模式下，_adb_ (USB 调试)是不必要的，且镜像被禁用。
-
-启用 OTG 模式:
-
-```bash
-scrcpy --otg
-# 如果有多个 USB 设备可用，则通过序列号选择
-scrcpy --otg -s 0123456789abcdef
-```
-
-只开启 HID 键盘 或 HID 鼠标 是可行的：
-
-```bash
-scrcpy --otg --hid-keyboard              # 只开启 HID 键盘
-scrcpy --otg --hid-mouse                 # 只开启 HID 鼠标
-scrcpy --otg --hid-keyboard --hid-mouse  # 开启 HID 键盘 和 HID 鼠标
-# 为了方便，默认两者都开启
