-
-The server is pushed to the device by the client on startup.
-
-To debug it, enable the server debugger during configuration:

-```bash
-meson x -Dserver_debugger=true
-# or, if x is already configured
-meson configure x -Dserver_debugger=true
-```

-meson x -Dserver_debugger=true -Dserver_debugger_method=old
-# or, if x is already configured
-meson configure x -Dserver_debugger=true -Dserver_debugger_method=old
-```
-
-Then recompile.
-
-When you start scrcpy, it will start a debugger on port 5005 on the device.
-Redirect that port to the computer:
-
-```bash
-adb forward tcp:5005 tcp:5005
-```

 # Frequently Asked Questions

+## Common issues
+
+The application is very young, it is not unlikely that you encounter problems
+with it.
+
 Here are the common reported problems and their status.


-## `adb` issues
+### On Windows, my device is not detected

-`scrcpy` execute `adb` commands to initialize the connection with the device. If
-`adb` fails, then scrcpy will not work.
+The most common is your device not being detected by `adb`, or is unauthorized.
+Check everything is ok by calling:

-In that case, it will print this error:
+    adb devices

->     ERROR: "adb push" returned with value 1
-
-This is typically not a bug in _scrcpy_, but a problem in your environment.
-
-To find out the cause, execute:
-
-```bash
-adb devices
-```
-
-### `adb` not found
-
-You need `adb` accessible from your `PATH`.
-
-On Windows, the current directory is in your `PATH`, and `adb.exe` is included
-in the release, so it should work out-of-the-box.
-
-
-### Device unauthorized
-
-Check [stackoverflow][device-unauthorized].
-
-[device-unauthorized]: https://stackoverflow.com/questions/23081263/adb-android-device-unauthorized
-
-
-### Device not detected
-
->     adb: error: failed to get feature set: no devices/emulators found
-
-If your device is not detected, you may need some [drivers] (on Windows).
+Windows may need some [drivers] to detect your device.

 [drivers]: https://developer.android.com/studio/run/oem-usb.html


-### Several devices connected
-
-If several devices are connected, you will encounter this error:
-
->     adb: error: failed to get feature set: more than one device/emulator
-
-the identifier of the device you want to mirror must be provided:
-
-```bash
-scrcpy -s 01234567890abcdef
-```
-
-Note that if your device is connected over TCP/IP, you'll get this message:
-
->     adb: error: more than one device/emulator
->     ERROR: "adb reverse" returned with value 1
->     WARN: 'adb reverse' failed, fallback to 'adb forward'
-
-This is expected (due to a bug on old Android versions, see [#5]), but in that
-case, scrcpy fallbacks to a different method, which should work.
-
-[#5]: https://github.com/Genymobile/scrcpy/issues/5
-
-
-### Conflicts between adb versions
-
->     adb server version (41) doesn't match this client (39); killing...
-
-This error occurs when you use several `adb` versions simultaneously. You must
-find the program using a different `adb` version, and use the same `adb` version
-everywhere.
-
-You could overwrite the `adb` binary in the other program, or ask _scrcpy_ to
-use a specific `adb` binary, by setting the `ADB` environment variable:
-
-```bash
-set ADB=/path/to/your/adb
-scrcpy
-```
-
-
-### Device disconnected
-
-If _scrcpy_ stops itself with the warning "Device disconnected", then the
-`adb` connection has been closed.
-
-Try with another USB cable or plug it into another USB port. See [#281] and
-[#283].

-## Client issues
-
-### The quality is low
-
-If the definition of your client window is smaller than that of your device
-screen, then you might get poor quality, especially visible on text (see [#40]).
-
-[#40]: https://github.com/Genymobile/scrcpy/issues/40
-
-To improve downscaling quality, trilinear filtering is enabled automatically

-
-```
-scrcpy --render-driver=opengl
+```bash
+meson x --buildtype release -Dhidpi_support=false

-## Crashes
-

-device is not able to encode at the given definition:

-> android.media.MediaCodec$CodecException: Error 0xfffffc0e

-> ```
-> ERROR: Exception on thread Thread[main,5,main]

-Just try with a lower definition:
-
-```
-scrcpy -m 1920
-scrcpy -m 1024
-scrcpy -m 800
-```
-
-You could also try another [encoder](README.md#encoder).
-
-
-## Command line on Windows
-
-Some Windows users are not familiar with the command line. Here is how to open a
-terminal and run `scrcpy` with arguments:
-
- 1. Press <kbd>Windows</kbd>+<kbd>r</kbd>, this opens a dialog box.
- 2. Type `cmd` and press <kbd>Enter</kbd>, this opens a terminal.
- 3. Go to your _scrcpy_ directory, by typing (adapt the path):
-
-    ```bat
-    cd C:\Users\user\Downloads\scrcpy-win64-xxx
-    ```
-
-    and press <kbd>Enter</kbd>
- 4. Type your command. For example:
-
-    ```bat
-    scrcpy --record file.mkv
-    ```
-
-If you plan to always use the same arguments, create a file `myscrcpy.bat`
-(enable [show file extensions] to avoid confusion) in the `scrcpy` directory,
-containing your command. For example:
-
-```bat
-scrcpy --prefer-text --turn-screen-off --stay-awake
-```
-
-Then just double-click on that file.
-
-You could also edit (a copy of) `scrcpy-console.bat` or `scrcpy-noconsole.vbs`
-to add some arguments.

-# scrcpy (v1.16)
-
-Aplikasi ini menyediakan tampilan dan kontrol perangkat Android yang terhubung pada USB (atau [melalui TCP/IP][article-tcpip]). Ini tidak membutuhkan akses _root_ apa pun. Ini bekerja pada _GNU/Linux_, _Windows_ and _macOS_.
-
-![screenshot](assets/screenshot-debian-600.jpg)
-
-Ini berfokus pada:
-
-  - **keringanan** (asli, hanya menampilkan layar perangkat)
-  - **kinerja** (30~60fps)
-  - **kualitas** (1920×1080 atau lebih)
-  - **latensi** rendah ([35~70ms][lowlatency])
-  - **waktu startup rendah** (~1 detik untuk menampilkan gambar pertama)
-  - **tidak mengganggu** (tidak ada yang terpasang di perangkat)
-
-
-[lowlatency]: https://github.com/Genymobile/scrcpy/pull/646
-
-
-## Persyaratan
-Perangkat Android membutuhkan setidaknya API 21 (Android 5.0).
-
-Pastikan Anda [mengaktifkan debugging adb][enable-adb] pada perangkat Anda.
-
-[enable-adb]: https://developer.android.com/studio/command-line/adb.html#Enabling
-
-Di beberapa perangkat, Anda juga perlu mengaktifkan [opsi tambahan][control] untuk mengontrolnya menggunakan keyboard dan mouse.
-

-```
-Anda membutuhkan `adb`, dapat diakses dari `PATH` Anda. Jika Anda belum memilikinya:
-
-```bash
-brew cask install android-platform-tools
-```
-
-Anda juga dapat [membangun aplikasi secara manual][BUILD].
-
-
-## Menjalankan
-
-Pasang perangkat Android, dan jalankan:
-
-```bash
-scrcpy
-```
-
-Ini menerima argumen baris perintah, didaftarkan oleh:
-
-```bash
-scrcpy --help
-```
-
-## Fitur
-
-### Menangkap konfigurasi
-
-#### Mengurangi ukuran
-
-Kadang-kadang, berguna untuk mencerminkan perangkat Android dengan definisi yang lebih rendah untuk meningkatkan kinerja.
-
-Untuk membatasi lebar dan tinggi ke beberapa nilai (mis. 1024):
-
-```bash
-scrcpy --max-size 1024
-scrcpy -m 1024  # versi pendek
-```
-
-Dimensi lain dihitung agar rasio aspek perangkat dipertahankan.
-Dengan begitu, perangkat 1920×1080 akan dicerminkan pada 1024×576.
-
-#### Ubah kecepatan bit
-
-Kecepatan bit default adalah 8 Mbps. Untuk mengubah bitrate video (mis. Menjadi 2 Mbps):
-
-```bash
-scrcpy --bit-rate 2M
-scrcpy -b 2M  # versi pendek
-```
-
-#### Batasi frekuensi gambar
-
-Kecepatan bingkai pengambilan dapat dibatasi:
-
-```bash
-scrcpy --max-fps 15
-```
-
-Ini secara resmi didukung sejak Android 10, tetapi dapat berfungsi pada versi sebelumnya.
-
-#### Memotong
-
-Layar perangkat dapat dipotong untuk mencerminkan hanya sebagian dari layar.
-
-Ini berguna misalnya untuk mencerminkan hanya satu mata dari Oculus Go:
-
-```bash
-scrcpy --crop 1224:1440:0:0   # 1224x1440 Mengimbangi (0,0)
-```
-
-Jika `--max-size` juga ditentukan, pengubahan ukuran diterapkan setelah pemotongan.
-
-
-#### Kunci orientasi video
-
-Untuk mengunci orientasi pencerminan:
-
-```bash
-scrcpy --lock-video-orientation 0   # orientasi alami
-scrcpy --lock-video-orientation 1   # 90° berlawanan arah jarum jam
-scrcpy --lock-video-orientation 2   # 180°
-scrcpy --lock-video-orientation 3   # 90° searah jarum jam
-```
-
-Ini mempengaruhi orientasi perekaman.
-
-
-### Rekaman
-
-Anda dapat merekam layar saat melakukan mirroring:
-
-```bash
-scrcpy --record file.mp4
-scrcpy -r file.mkv
-```
-
-Untuk menonaktifkan pencerminan saat merekam:
-
-```bash
-scrcpy --no-display --record file.mp4
-scrcpy -Nr file.mkv
-# berhenti merekam dengan Ctrl+C
-```
-
-"Skipped frames" are recorded, even if they are not displayed in real time (for
-performance reasons). Frames are _timestamped_ on the device, so [packet delay
-variation] does not impact the recorded file.
-
-"Frame yang dilewati" direkam, meskipun tidak ditampilkan secara real time (untuk alasan performa). Bingkai *diberi stempel waktu* pada perangkat, jadi [variasi penundaan paket] tidak memengaruhi file yang direkam.
-
-[variasi penundaan paket]: https://en.wikipedia.org/wiki/Packet_delay_variation
-
-
-### Koneksi
-
-#### Wireless
-
-_Scrcpy_ menggunakan `adb` untuk berkomunikasi dengan perangkat, dan` adb` dapat [terhubung] ke perangkat melalui TCP / IP:
-
-1. Hubungkan perangkat ke Wi-Fi yang sama dengan komputer Anda.
-2. Dapatkan alamat IP perangkat Anda (dalam Pengaturan → Tentang ponsel → Status).
-3. Aktifkan adb melalui TCP / IP pada perangkat Anda: `adb tcpip 5555`.
-4. Cabut perangkat Anda.
-5. Hubungkan ke perangkat Anda: `adb connect DEVICE_IP: 5555` (*ganti* *`DEVICE_IP`*).
-6. Jalankan `scrcpy` seperti biasa.
-
-Mungkin berguna untuk menurunkan kecepatan bit dan definisi:
-
-```bash
-scrcpy --bit-rate 2M --max-size 800
-scrcpy -b2M -m800  # versi pendek
-```
-
-[terhubung]: https://developer.android.com/studio/command-line/adb.html#wireless
-
-
-#### Multi-perangkat
-
-Jika beberapa perangkat dicantumkan di `adb devices`, Anda harus menentukan _serial_:
-
-```bash
-scrcpy --serial 0123456789abcdef
-scrcpy -s 0123456789abcdef  # versi pendek
-```
-
-If the device is connected over TCP/IP:
-
-```bash
-scrcpy --serial 192.168.0.1:5555
-scrcpy -s 192.168.0.1:5555  # versi pendek
-```
-
-Anda dapat memulai beberapa contoh _scrcpy_ untuk beberapa perangkat.
-
-#### Mulai otomatis pada koneksi perangkat
-
-Anda bisa menggunakan [AutoAdb]:
-
-```bash
-autoadb scrcpy -s '{}'
-```
-
-[AutoAdb]: https://github.com/rom1v/autoadb
-
-#### Koneksi via SSH tunnel
-
-Untuk menyambung ke perangkat jarak jauh, dimungkinkan untuk menghubungkan klien `adb` lokal ke server `adb` jarak jauh (asalkan mereka menggunakan versi yang sama dari _adb_ protocol):
-
-```bash
-adb kill-server    # matikan server adb lokal di 5037
-ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 komputer_jarak_jauh_anda
-# jaga agar tetap terbuka
-```
-
-Dari terminal lain:
-
-```bash
-scrcpy
-```
-
-Untuk menghindari mengaktifkan penerusan port jarak jauh, Anda dapat memaksa sambungan maju sebagai gantinya (perhatikan `-L`, bukan` -R`):
-
-```bash
-adb kill-server    # matikan server adb lokal di 5037
-ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 komputer_jarak_jauh_anda
-# jaga agar tetap terbuka
-```
-
-Dari terminal lain:
-
-```bash
-scrcpy --force-adb-forward
-```
-
-Seperti koneksi nirkabel, mungkin berguna untuk mengurangi kualitas:
-
-```
-scrcpy -b2M -m800 --max-fps 15
-```
-
-### Konfigurasi Jendela
-
-#### Judul
-
-Secara default, judul jendela adalah model perangkat. Itu bisa diubah:
-
-```bash
-scrcpy --window-title 'Perangkat Saya'
-```
-
-#### Posisi dan ukuran
-
-Posisi dan ukuran jendela awal dapat ditentukan:
-
-```bash
-scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
-```
-
-#### Jendela tanpa batas
-
-Untuk menonaktifkan dekorasi jendela:
-
-```bash
-scrcpy --window-borderless
-```
-
-#### Selalu di atas
-
-Untuk menjaga jendela scrcpy selalu di atas:
-
-```bash
-scrcpy --always-on-top
-```
-
-#### Layar penuh
-
-Aplikasi dapat dimulai langsung dalam layar penuh::
-
-```bash
-scrcpy --fullscreen
-scrcpy -f  # versi pendek
-```
-
-Layar penuh kemudian dapat diubah secara dinamis dengan <kbd>MOD</kbd>+<kbd>f</kbd>.
-
-#### Rotasi
-
-Jendela mungkin diputar:
-
-```bash
-scrcpy --rotation 1
-```
-
-Nilai yang mungkin adalah:
- - `0`: tidak ada rotasi
- - `1`: 90 derajat berlawanan arah jarum jam
- - `2`: 180 derajat
- - `3`: 90 derajat searah jarum jam
-
-Rotasi juga dapat diubah secara dinamis dengan <kbd>MOD</kbd>+<kbd>←</kbd>
-_(kiri)_ and <kbd>MOD</kbd>+<kbd>→</kbd> _(kanan)_.
-
-Perhatikan bahwa _scrcpy_ mengelola 3 rotasi berbeda::
- - <kbd>MOD</kbd>+<kbd>r</kbd> meminta perangkat untuk beralih antara potret dan lanskap (aplikasi yang berjalan saat ini mungkin menolak, jika mendukung orientasi yang diminta).
- - `--lock-video-orientation` mengubah orientasi pencerminan (orientasi video yang dikirim dari perangkat ke komputer). Ini mempengaruhi rekaman.
- - `--rotation` (atau <kbd>MOD</kbd>+<kbd>←</kbd>/<kbd>MOD</kbd>+<kbd>→</kbd>)
-   memutar hanya konten jendela. Ini hanya mempengaruhi tampilan, bukan rekaman.
-
-
-### Opsi pencerminan lainnya
-
-#### Hanya-baca
-
-Untuk menonaktifkan kontrol (semua yang dapat berinteraksi dengan perangkat: tombol input, peristiwa mouse, seret & lepas file):
-
-```bash
-scrcpy --no-control
-scrcpy -n
-```
-
-#### Layar
-
-Jika beberapa tampilan tersedia, Anda dapat memilih tampilan untuk cermin:
-
-```bash
-scrcpy --display 1
-```
-
-Daftar id tampilan dapat diambil dengan::
-
-```
-adb shell dumpsys display   # cari "mDisplayId=" di keluaran
-```
-
-Tampilan sekunder hanya dapat dikontrol jika perangkat menjalankan setidaknya Android 10 (jika tidak maka akan dicerminkan dalam hanya-baca).
-
-
-#### Tetap terjaga
-
-Untuk mencegah perangkat tidur setelah beberapa penundaan saat perangkat dicolokkan:
-
-```bash
-scrcpy --stay-awake
-scrcpy -w
-```
-
-Keadaan awal dipulihkan ketika scrcpy ditutup.
-
-
-#### Matikan layar
-
-Dimungkinkan untuk mematikan layar perangkat saat pencerminan mulai dengan opsi baris perintah:
-
-```bash
-scrcpy --turn-screen-off
-scrcpy -S
-```
-
-Atau dengan menekan <kbd>MOD</kbd>+<kbd>o</kbd> kapan saja.
-
-Untuk menyalakannya kembali, tekan <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd>.
-
-Di Android, tombol `POWER` selalu menyalakan layar. Untuk kenyamanan, jika `POWER` dikirim melalui scrcpy (melalui klik kanan atau<kbd>MOD</kbd>+<kbd>p</kbd>), itu akan memaksa untuk mematikan layar setelah penundaan kecil (atas dasar upaya terbaik).
-Tombol fisik `POWER` masih akan menyebabkan layar dihidupkan.
-
-Ini juga berguna untuk mencegah perangkat tidur:
-
-```bash
-scrcpy --turn-screen-off --stay-awake
-scrcpy -Sw
-```
-
-#### Render frame kedaluwarsa
-
-Secara default, untuk meminimalkan latensi, _scrcpy_ selalu menampilkan frame yang terakhir didekodekan tersedia, dan menghapus frame sebelumnya.
-
-Untuk memaksa rendering semua frame (dengan kemungkinan peningkatan latensi), gunakan:
-
-```bash
-scrcpy --render-expired-frames
-```
-
-#### Tunjukkan sentuhan
-
-Untuk presentasi, mungkin berguna untuk menunjukkan sentuhan fisik (pada perangkat fisik).
-
-Android menyediakan fitur ini di _Opsi Pengembang_.
-
-_Scrcpy_ menyediakan opsi untuk mengaktifkan fitur ini saat mulai dan mengembalikan nilai awal saat keluar:
-
-```bash
-scrcpy --show-touches
-scrcpy -t
-```
-
-Perhatikan bahwa ini hanya menunjukkan sentuhan _fisik_ (dengan jari di perangkat).
-
-
-#### Nonaktifkan screensaver
-
-Secara default, scrcpy tidak mencegah screensaver berjalan di komputer.
-
-Untuk menonaktifkannya:
-
-```bash
-scrcpy --disable-screensaver
-```
-
-
-### Kontrol masukan
-
-#### Putar layar perangkat
-
-Tekan <kbd>MOD</kbd>+<kbd>r</kbd> untuk beralih antara mode potret dan lanskap.
-
-Perhatikan bahwa itu berputar hanya jika aplikasi di latar depan mendukung orientasi yang diminta.
-
-#### Salin-tempel
-
-Setiap kali papan klip Android berubah, secara otomatis disinkronkan ke papan klip komputer.
-
-Apa saja <kbd>Ctrl</kbd> pintasan diteruskan ke perangkat. Khususnya:
- - <kbd>Ctrl</kbd>+<kbd>c</kbd> biasanya salinan
- - <kbd>Ctrl</kbd>+<kbd>x</kbd> biasanya memotong
- - <kbd>Ctrl</kbd>+<kbd>v</kbd> biasanya menempel (setelah sinkronisasi papan klip komputer-ke-perangkat)
-
-Ini biasanya berfungsi seperti yang Anda harapkan.
-
-Perilaku sebenarnya tergantung pada aplikasi yang aktif. Sebagai contoh,
-_Termux_ mengirim SIGINT ke <kbd>Ctrl</kbd>+<kbd>c</kbd> sebagai gantinya, dan _K-9 Mail_ membuat pesan baru.
-
-Untuk menyalin, memotong dan menempel dalam kasus seperti itu (tetapi hanya didukung di Android> = 7):
- - <kbd>MOD</kbd>+<kbd>c</kbd> injeksi `COPY` _(salin)_
- - <kbd>MOD</kbd>+<kbd>x</kbd> injeksi `CUT` _(potong)_
- - <kbd>MOD</kbd>+<kbd>v</kbd> injeksi `PASTE` (setelah sinkronisasi papan klip komputer-ke-perangkat)
-
-Tambahan, <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> memungkinkan untuk memasukkan teks papan klip komputer sebagai urutan peristiwa penting. Ini berguna ketika komponen tidak menerima penempelan teks (misalnya di _Termux_), tetapi dapat merusak konten non-ASCII.
-
-**PERINGATAN:** Menempelkan papan klip komputer ke perangkat (baik melalui
-<kbd>Ctrl</kbd>+<kbd>v</kbd> or <kbd>MOD</kbd>+<kbd>v</kbd>) menyalin konten ke clipboard perangkat. Akibatnya, aplikasi Android apa pun dapat membaca kontennya. Anda harus menghindari menempelkan konten sensitif (seperti kata sandi) seperti itu.
-
-
-#### Cubit untuk memperbesar/memperkecil
-
-Untuk mensimulasikan "cubit-untuk-memperbesar/memperkecil": <kbd>Ctrl</kbd>+_klik-dan-pindah_.
-
-Lebih tepatnya, tahan <kbd>Ctrl</kbd> sambil menekan tombol klik kiri. Hingga tombol klik kiri dilepaskan, semua gerakan mouse berskala dan memutar konten (jika didukung oleh aplikasi) relatif ke tengah layar.
-
-Secara konkret, scrcpy menghasilkan kejadian sentuh tambahan dari "jari virtual" di lokasi yang dibalik melalui bagian tengah layar.
-
-
-#### Preferensi injeksi teks
-
-Ada dua jenis [peristiwa][textevents] dihasilkan saat mengetik teks:
- _peristiwa penting_, menandakan bahwa tombol ditekan atau dilepaskan;
- _peristiwa teks_, menandakan bahwa teks telah dimasukkan.
-
-Secara default, huruf dimasukkan menggunakan peristiwa kunci, sehingga keyboard berperilaku seperti yang diharapkan dalam game (biasanya untuk tombol WASD).
-
-Tapi ini mungkin [menyebabkan masalah][prefertext]. Jika Anda mengalami masalah seperti itu, Anda dapat menghindarinya dengan:
-
-```bash
-scrcpy --prefer-text
-```
-
-(tapi ini akan merusak perilaku keyboard dalam game)
-
-[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
-[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
-
-
-#### Ulangi kunci
-
-Secara default, menahan tombol akan menghasilkan peristiwa kunci yang berulang. Ini dapat menyebabkan masalah kinerja di beberapa game, di mana acara ini tidak berguna.
-
-Untuk menghindari penerusan peristiwa penting yang berulang:
-
-```bash
-scrcpy --no-key-repeat
-```
-
-
-### Seret/jatuhkan file
-
-#### Pasang APK
-
-Untuk menginstal APK, seret & lepas file APK (diakhiri dengan `.apk`) ke jendela _scrcpy_.
-
-Tidak ada umpan balik visual, log dicetak ke konsol.
-
-
-#### Dorong file ke perangkat
-
-Untuk mendorong file ke `/sdcard/` di perangkat, seret & jatuhkan file (non-APK) ke jendela _scrcpy_.
-
-Tidak ada umpan balik visual, log dicetak ke konsol.
-
-Direktori target dapat diubah saat mulai:
-
-```bash
-scrcpy --push-target /sdcard/foo/bar/
-```
-
-
-### Penerusan audio
-
-Audio tidak diteruskan oleh _scrcpy_. Gunakan [sndcpy].
-
-Lihat juga [Masalah #14].
-
-[sndcpy]: https://github.com/rom1v/sndcpy
-[Masalah #14]: https://github.com/Genymobile/scrcpy/issues/14
-
-
-## Pintasan
-
-Dalam daftar berikut, <kbd>MOD</kbd> adalah pengubah pintasan. Secara default, ini (kiri) <kbd>Alt</kbd> atau (kiri) <kbd>Super</kbd>.
-
-Ini dapat diubah menggunakan `--shortcut-mod`. Kunci yang memungkinkan adalah `lctrl`,`rctrl`, `lalt`,` ralt`, `lsuper` dan` rsuper`. Sebagai contoh:
-
-```bash
-# gunakan RCtrl untuk jalan pintas
-scrcpy --shortcut-mod=rctrl
-
-# gunakan baik LCtrl+LAlt atau LSuper untuk jalan pintas
-scrcpy --shortcut-mod=lctrl+lalt,lsuper
-```
-
-_<kbd>[Super]</kbd> biasanya adalah <kbd>Windows</kbd> atau <kbd>Cmd</kbd> key._
-
-[Super]: https://en.wikipedia.org/wiki/Super_key_(keyboard_button)

-[ebuild-link]: https://github.com/maggu2810/maggu2810-overlay/tree/master/app-mobilephone/scrcpy
-
-
-### Windows (윈도우)
-
-윈도우 상에서, 간단하게 설치하기 위해 종속성이 있는 사전 구축된 아카이브가 제공됩니다 (`adb` 포함) :
-해당 파일은 Readme원본 링크를 통해서 다운로드가 가능합니다.
- - [`scrcpy-win`][direct-win]
-
-[direct-win]: https://github.com/Genymobile/scrcpy/blob/master/README.md#windows
-
-
-[어플을 직접 설치][BUILD] 할 수도 있습니다.
-
-
-### macOS (맥 OS)
-
-이 어플리케이션은 아래 사항을 따라 설치한다면 [Homebrew] 에서도 사용 가능합니다 :
-
-[Homebrew]: https://brew.sh/
-
-```bash
-brew install scrcpy
-```
-
-`PATH` 로부터 접근 가능한 `adb` 가 필요합니다. 아직 설치하지 않았다면 다음을 따라 설치해야 합니다 :
-
-```bash
-brew cask install android-platform-tools
-```
-
-[어플을 직접 설치][BUILD] 할 수도 있습니다.
-
-
-## 실행
-
-안드로이드 디바이스를 연결하고 실행하십시오:
-
-```bash
-scrcpy
-```
-
-다음과 같이 명령창 옵션 기능도 제공합니다.
-
-```bash
-scrcpy --help
-```
-
-## 기능
-
-### 캡쳐 환경 설정
-
-
-###사이즈 재정의
-
-가끔씩 성능을 향상시키기위해 안드로이드 디바이스를 낮은 해상도에서 미러링하는 것이 유용할 때도 있습니다.
-
-너비와 높이를 제한하기 위해 특정 값으로 지정할 수 있습니다 (e.g. 1024) :
-
-```bash
-scrcpy --max-size 1024
-scrcpy -m 1024  # 축약 버전
-```
-
-이 외의 크기도 디바이스의 가로 세로 비율이 유지된 상태에서 계산됩니다.
-이러한 방식으로 디바이스 상에서 1920×1080 는 모니터 상에서1024×576로 미러링될 것 입니다.
-
-
-### bit-rate 변경
-
-기본 bit-rate 는 8 Mbps입니다. 비디오 bit-rate 를 변경하기 위해선 다음과 같이 입력하십시오 (e.g. 2 Mbps로 변경):
-
-```bash
-scrcpy --bit-rate 2M
-scrcpy -b 2M  # 축약 버전
-```
-
-###프레임 비율 제한
-
-안드로이드 버전 10이상의 디바이스에서는, 다음의 명령어로 캡쳐 화면의 프레임 비율을 제한할 수 있습니다:
-
-```bash
-scrcpy --max-fps 15
-```
-
-
-### Crop (잘라내기)
-
-디바이스 화면은 화면의 일부만 미러링하기 위해 잘라질 것입니다.
-
-예를 들어, *Oculus Go* 의 한 쪽 눈만 미러링할 때 유용합니다 :
-
-```bash
-scrcpy --crop 1224:1440:0:0   # 1224x1440 at offset (0,0)
-scrcpy -c 1224:1440:0:0       # 축약 버전
-```
-
-만약 `--max-size` 도 지정하는 경우, 잘라낸 다음에 재정의된 크기가 적용될 것입니다.
-
-
-### 화면 녹화
-
-미러링하는 동안 화면 녹화를 할 수 있습니다 :
-
-```bash
-scrcpy --record file.mp4
-scrcpy -r file.mkv
-```
-
-녹화하는 동안 미러링을 멈출 수 있습니다 :
-
-```bash
-scrcpy --no-display --record file.mp4
-scrcpy -Nr file.mkv
-# Ctrl+C 로 녹화를 중단할 수 있습니다.
-# 윈도우 상에서 Ctrl+C 는 정상정으로 종료되지 않을 수 있으므로, 디바이스 연결을 해제하십시오.
-```
-
-"skipped frames" 은 모니터 화면에 보여지지 않았지만 녹화되었습니다 ( 성능 문제로 인해 ). 프레임은 디바이스 상에서 _타임 스탬프 ( 어느 시점에 데이터가 존재했다는 사실을 증명하기 위해 특정 위치에 시각을 표시 )_ 되었으므로, [packet delay
-variation] 은 녹화된 파일에 영향을 끼치지 않습니다.
-
-[packet delay variation]: https://en.wikipedia.org/wiki/Packet_delay_variation
-
-## 연결
-
-### 무선연결
-
-_Scrcpy_ 장치와 정보를 주고받기 위해 `adb` 를 사용합니다.  `adb` 는 TCIP/IP 를 통해 디바이스와 [연결][connect] 할 수 있습니다 :
-
-1. 컴퓨터와 디바이스를 동일한 Wi-Fi 에 연결합니다.
-2. 디바이스의 IP address 를 확인합니다 (설정 → 내 기기 → 상태 / 혹은 인터넷에 '내 IP'검색 시 확인 가능합니다. ).
-3. TCP/IP 를 통해 디바이스에서 adb 를 사용할 수 있게 합니다: `adb tcpip 5555`.
-4. 디바이스 연결을 해제합니다.
-5. adb 를 통해 디바이스에 연결을 합니다\: `adb connect DEVICE_IP:5555` _(`DEVICE_IP` 대신)_.
-6. `scrcpy` 실행합니다.
-
-다음은 bit-rate 와 해상도를 줄이는데 유용합니다 :
-
-```bash
-scrcpy --bit-rate 2M --max-size 800
-scrcpy -b2M -m800  # 축약 버전
-```
-
-[connect]: https://developer.android.com/studio/command-line/adb.html#wireless
-
-
-
-### 여러 디바이스 사용 가능
-
-만약에 여러 디바이스들이 `adb devices` 목록에 표시되었다면, _serial_ 을 명시해야합니다:
-
-```bash
-scrcpy --serial 0123456789abcdef
-scrcpy -s 0123456789abcdef  # 축약 버전
-```
-
-_scrcpy_ 로 여러 디바이스를 연결해 사용할 수 있습니다.
-
-
-#### SSH tunnel
-
-떨어져 있는 디바이스와 연결하기 위해서는, 로컬 `adb` client와 떨어져 있는 `adb` 서버를 연결해야 합니다.  (디바이스와 클라이언트가 동일한 버전의 _adb_ protocol을 사용할 경우에 제공됩니다.):
-
-```bash
-adb kill-server    # 5037의 로컬 local adb server를 중단
-ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
-# 실행 유지
-```
-
-다른 터미널에서는 :
-
-```bash
-scrcpy
-```
-
-무선 연결과 동일하게, 화질을 줄이는 것이 나을 수 있습니다:
-
-```
-scrcpy -b2M -m800 --max-fps 15
-```
-
-## Window에서의 배치
-
-### 맞춤형 window 제목
-
-기본적으로, window의 이름은 디바이스의 모델명 입니다.
-다음의 명령어를 통해 변경하세요.
-
-```bash
-scrcpy --window-title 'My device'
-```
-
-
-### 배치와 크기
-
-초기 window창의 배치와 크기는 다음과 같이 설정할 수 있습니다:
-
-```bash
-scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
-```
-
-
-### 경계 없애기
-
-윈도우 장식(경계선 등)을 다음과 같이 제거할 수 있습니다:
-
-```bash
-scrcpy --window-borderless
-```
-
-### 항상 모든 윈도우 위에 실행창 고정
-
-이 어플리케이션의 윈도우 창은 다음의 명령어로 다른 window 위에 디스플레이 할 수 있습니다:
-
-```bash
-scrcpy --always-on-top
-scrcpy -T  # 축약 버전
-```
-
-### 전체 화면
-
-이 어플리케이션은 전체화면으로 바로 시작할 수 있습니다.
-
-```bash
-scrcpy --fullscreen
-scrcpy -f  # short version
-```
-
-전체 화면은  `Ctrl`+`f`키로 끄거나 켤 수 있습니다.
-
-
-## 다른 미러링 옵션
-
-### 읽기 전용(Read-only)
-
-권한을 제한하기 위해서는 (디바이스와 관련된 모든 것: 입력 키, 마우스 이벤트 , 파일의 드래그 앤 드랍(drag&drop)):
-
-```bash
-scrcpy --no-control
-scrcpy -n
-```
-
-### 화면 끄기
-
-미러링을 실행하는 와중에 디바이스의 화면을 끌 수 있게 하기 위해서는
-다음의 커맨드 라인 옵션을(command line option) 입력하세요:
-
-```bash
-scrcpy --turn-screen-off
-scrcpy -S
-```
-
-혹은 `Ctrl`+`o`을 눌러 언제든지 디바이스의 화면을 끌 수 있습니다.
-
-다시 화면을 켜기 위해서는`POWER` (혹은 `Ctrl`+`p`)를 누르세요.
-
-
-### 유효기간이 지난 프레임 제공 (Render expired frames)
-
-디폴트로, 대기시간을 최소화하기 위해 _scrcpy_ 는 항상 마지막으로 디코딩된 프레임을 제공합니다
-과거의 프레임은 하나씩 삭제합니다.
-
-모든 프레임을 강제로 렌더링하기 위해서는 (대기 시간이 증가될 수 있습니다)
-다음의 명령어를 사용하세요:
-
-```bash
-scrcpy --render-expired-frames
-```
-
-
-### 화면에 터치 나타내기
-
-발표를 할 때, 물리적인 기기에 한 물리적 터치를 나타내는 것이 유용할 수 있습니다.
-
-안드로이드 운영체제는 이런 기능을 _Developers options_에서 제공합니다.
-
-_Scrcpy_ 는 이런 기능을 시작할 때와 종료할 때 옵션으로 제공합니다.
-
-```bash
-scrcpy --show-touches
-scrcpy -t
-```
-
-화면에 _물리적인 터치만_ 나타나는 것에 유의하세요 (손가락을 디바이스에 대는 행위).
-
-
-### 입력 제어
-
-#### 복사-붙여넣기
-
-컴퓨터와 디바이스 양방향으로 클립보드를 복사하는 것이 가능합니다:
-
- - `Ctrl`+`c` 디바이스의 클립보드를 컴퓨터로 복사합니다;
- - `Ctrl`+`Shift`+`v` 컴퓨터의 클립보드를 디바이스로 복사합니다;
- - `Ctrl`+`v` 컴퓨터의 클립보드를 text event 로써 _붙여넣습니다_  ( 그러나, ASCII 코드가 아닌 경우 실행되지 않습니다 )
-
-#### 텍스트 삽입 우선 순위
-
-텍스트를 입력할 때 생성되는 두 가지의 [events][textevents] 가 있습니다:
- - _key events_, 키가 눌려있는 지에 대한 신호;
- - _text events_, 텍스트가 입력되었는지에 대한 신호.
-
-기본적으로, 글자들은 key event 를 이용해 입력되기 때문에, 키보드는 게임에서처럼 처리합니다 ( 보통 WASD 키에 대해서 ).
-
-그러나 이는 [issues 를 발생][prefertext]시킵니다. 이와 관련된 문제를 접할 경우, 아래와 같이 피할 수 있습니다:
-
-```bash
-scrcpy --prefer-text
-```
-
-( 그러나 이는 게임에서의 처리를 중단할 수 있습니다 )
-
-[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
-[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
-
-
-### 파일 드랍
-
-### APK 실행하기
-
-APK를 실행하기 위해서는, APK file(파일명이`.apk`로 끝나는 파일)을  드래그하고 _scrcpy_ window에 드랍하세요 (drag and drop)
-
-시각적인 피드백은 없고,log 하나가 콘솔에 출력될 것입니다.
-
-### 디바이스에 파일 push하기
-
-디바이스의`/sdcard/`에 파일을 push하기 위해서는,
-APK파일이 아닌 파일을_scrcpy_ window에 드래그하고 드랍하세요.(drag and drop).
-
-시각적인 피드백은 없고,log 하나가 콘솔에 출력될 것입니다.
-
-해당 디렉토리는 시작할 때 변경이 가능합니다:
-
-```bash
-scrcpy --push-target /sdcard/foo/bar/
-```
-
-### 오디오의 전달
-
-_scrcpy_는 오디오를 직접 전달해주지 않습니다. [USBaudio] (Linux-only)를 사용하세요.
-
-추가적으로 [issue #14]를 참고하세요.
-

 If `--max-size` is also specified, resizing is applied after cropping.


-#### Lock video orientation
-
-
-To lock the orientation of the mirroring:
-
-```bash
-scrcpy --lock-video-orientation     # initial (current) orientation
-scrcpy --lock-video-orientation 0   # natural orientation
-scrcpy --lock-video-orientation 1   # 90° counterclockwise
-scrcpy --lock-video-orientation 2   # 180°
-scrcpy --lock-video-orientation 3   # 90° clockwise
-```
-
-This affects recording orientation.
-
-The [window may also be rotated](#rotation) independently.
-
-
-#### Encoder
-
-Some devices have more than one encoder, and some of them may cause issues or
-crash. It is possible to select a different encoder:
-
-```bash
-scrcpy --encoder OMX.qcom.video.encoder.avc
-```

-scrcpy --record file.mp4
-scrcpy -r file.mkv
-```
-
-To disable mirroring while recording:
-

-#### 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 -N  # --no-display to disable mirroring window
-```
-
-(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].

+### Wireless

 _Scrcpy_ uses `adb` to communicate with the device, and `adb` can [connect] to a
 device over TCP/IP:

 1. Connect the device to the same Wi-Fi as your computer.
-2. Get your device IP address, in Settings → About phone → Status, or by
-   executing this command:

-
+2. Get your device IP address (in Settings → About phone → Status).
 3. Enable adb over TCP/IP on your device: `adb tcpip 5555`.
 4. Unplug your device.
 5. Connect to your device: `adb connect DEVICE_IP:5555` _(replace `DEVICE_IP`)_.

-You could use [AutoAdb]:
-
-```bash
-autoadb scrcpy -s '{}'
-```
-
-[AutoAdb]: https://github.com/rom1v/autoadb
-
-#### SSH tunnel
-
-To connect to a remote device, it is possible to connect a local `adb` client to
-a remote `adb` server (provided they use the same version of the _adb_
-protocol):
-
-```bash
-adb kill-server    # kill the local adb server on 5037
-ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
-# keep this open
-```
-
-From another terminal:
-
-```bash
-scrcpy
-```
-
-To avoid enabling remote port forwarding, you could force a forward connection
-instead (notice the `-L` instead of `-R`):
-
-```bash
-adb kill-server    # kill the local adb server on 5037
-ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 your_remote_computer
-# keep this open
-```
-
-From another terminal:
-
-```bash
-scrcpy --force-adb-forward
-```
-
-
-Like for wireless connections, it may be useful to reduce quality:
-
-```
-scrcpy -b2M -m800 --max-fps 15

-
-### Window configuration
-
-#### Title
-
-By default, the window title is the device model. It can be changed:
-
-```bash
-scrcpy --window-title 'My device'
-```
-
-#### Position and size
-
-The initial window position and size may be specified:
-
-```bash
-scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
-```
-
-#### Borderless
-
-To disable window decorations:
-
-```bash
-scrcpy --window-borderless
-```
-
-#### Always on top
-
-To keep the scrcpy window always on top:
-
-```bash
-scrcpy --always-on-top
-```

-#### Rotation

-The window may be rotated:
+### Always on top
+
+The window of app can always be above others by:

 ```bash
-scrcpy --rotation 1
-```
-
-Possibles values are:
- - `0`: no rotation
- - `1`: 90 degrees counterclockwise
- - `2`: 180 degrees
- - `3`: 90 degrees clockwise
-
-The rotation can also be changed dynamically with <kbd>MOD</kbd>+<kbd>←</kbd>
-_(left)_ and <kbd>MOD</kbd>+<kbd>→</kbd> _(right)_.
-
-Note that _scrcpy_ manages 3 different rotations:
- - <kbd>MOD</kbd>+<kbd>r</kbd> requests the device to switch between portrait
-   and landscape (the current running app may refuse, if it does support the
-   requested orientation).
- - [`--lock-video-orientation`](#lock-video-orientation) changes the mirroring
-   orientation (the orientation of the video sent from the device to the
-   computer). This affects the recording.
- - `--rotation` (or <kbd>MOD</kbd>+<kbd>←</kbd>/<kbd>MOD</kbd>+<kbd>→</kbd>)
-   rotates only the window content. This affects only the display, not the
-   recording.
-
-
-### Other mirroring options
-
-#### Read-only
-
-To disable controls (everything which can interact with the device: input keys,
-mouse events, drag&drop files):
-
-```bash
-scrcpy --no-control
-scrcpy -n
-```
-
-#### Display
-
-If several displays are available, it is possible to select the display to
-mirror:
-
-```bash
-scrcpy --display 1
-```
-
-The list of display ids can be retrieved by:
-
-```
-adb shell dumpsys display   # search "mDisplayId=" in the output
-```
-
-The secondary display may only be controlled if the device runs at least Android
-10 (otherwise it is mirrored in read-only).
-
-
-#### Stay awake
-
-To prevent the device to sleep after some delay when the device is plugged in:
-
-```bash
-scrcpy --stay-awake
-scrcpy -w
-```
-
-The initial state is restored when scrcpy is closed.
-
-
-#### Turn screen off
-
-It is possible to turn the device screen off while mirroring on start with a
-command-line option:
-
-```bash
-scrcpy --turn-screen-off
-scrcpy -S
-```
-
-Or by pressing <kbd>MOD</kbd>+<kbd>o</kbd> at any time.
-
-To turn it back on, press <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd>.
-
-On Android, the `POWER` button always turns the screen on. For convenience, if
-`POWER` is sent via scrcpy (via right-click or <kbd>MOD</kbd>+<kbd>p</kbd>), it
-will force to turn the screen off after a small delay (on a best effort basis).
-The physical `POWER` button will still cause the screen to be turned on.
-
-It can also be useful to prevent the device from sleeping:

-#### Disable screensaver
-
-By default, scrcpy does not prevent the screensaver to run on the computer.
-
-To disable it:
-
-```bash
-scrcpy --disable-screensaver
-```
-
-
-### Input control
-
-#### Rotate device screen
-
-Press <kbd>MOD</kbd>+<kbd>r</kbd> to switch between portrait and landscape
-modes.
-
-Note that it rotates only if the application in foreground supports the
-requested orientation.
-
-#### Copy-paste
-
-Any time the Android clipboard changes, it is automatically synchronized to the
-computer clipboard.
-
-Any <kbd>Ctrl</kbd> shortcut is forwarded to the device. In particular:
- - <kbd>Ctrl</kbd>+<kbd>c</kbd> typically copies
- - <kbd>Ctrl</kbd>+<kbd>x</kbd> typically cuts
- - <kbd>Ctrl</kbd>+<kbd>v</kbd> typically pastes (after computer-to-device
-   clipboard synchronization)
-
-This typically works as you expect.
-
-The actual behavior depends on the active application though. For example,
-_Termux_ sends SIGINT on <kbd>Ctrl</kbd>+<kbd>c</kbd> instead, and _K-9 Mail_
-composes a new message.
-
-To copy, cut and paste in such cases (but only supported on Android >= 7):
- - <kbd>MOD</kbd>+<kbd>c</kbd> injects `COPY`
- - <kbd>MOD</kbd>+<kbd>x</kbd> injects `CUT`
- - <kbd>MOD</kbd>+<kbd>v</kbd> injects `PASTE` (after computer-to-device
-   clipboard synchronization)
-
-In addition, <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> allows to inject the
-computer clipboard text as a sequence of key events. This is useful when the
-component does not accept text pasting (for example in _Termux_), but it can
-break non-ASCII content.
-
-**WARNING:** Pasting the computer clipboard to the device (either via
-<kbd>Ctrl</kbd>+<kbd>v</kbd> or <kbd>MOD</kbd>+<kbd>v</kbd>) copies the content
-into the device clipboard. As a consequence, any Android application could read
-its content. You should avoid to paste sensitive content (like passwords) that
-way.
-
-Some devices do not behave as expected when setting the device clipboard
-programmatically. An option `--legacy-paste` is provided to change the behavior
-of <kbd>Ctrl</kbd>+<kbd>v</kbd> and <kbd>MOD</kbd>+<kbd>v</kbd> so that they
-also inject the computer clipboard text as a sequence of key events (the same
-way as <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd>).
-
-#### Pinch-to-zoom
-
-To simulate "pinch-to-zoom": <kbd>Ctrl</kbd>+_click-and-move_.
-
-More precisely, hold <kbd>Ctrl</kbd> while pressing the left-click button. Until
-the left-click button is released, all mouse movements scale and rotate the
-content (if supported by the app) relative to the center of the screen.
-
-Concretely, scrcpy generates additional touch events from a "virtual finger" at
-a location inverted through the center of the screen.
-
-
-#### Text injection preference
-
-There are two kinds of [events][textevents] generated when typing text:
- - _key events_, signaling that a key is pressed or released;
- - _text events_, signaling that a text has been entered.
-
-By default, letters are injected using key events, so that the keyboard behaves
-as expected in games (typically for WASD keys).
-
-But this may [cause issues][prefertext]. If you encounter such a problem, you
-can avoid it by:
-
-```bash
-scrcpy --prefer-text
-```
-
-(but this will break keyboard behavior in games)
-
-[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
-[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
-
-
-#### Key repeat
-
-By default, holding a key down generates repeated key events. This can cause
-performance problems in some games, where these events are useless anyway.
-
-To avoid forwarding repeated key events:
-
-```bash
-scrcpy --no-key-repeat
-```
-
-
-#### Right-click and middle-click
-
-By default, right-click triggers BACK (or POWER on) and middle-click triggers
-HOME. To disable these shortcuts and forward the clicks to the device instead:
-
-```bash
-scrcpy --forward-all-clicks
-```

+scrcpy --no-control
+scrcpy -n
+```
+
+### Turn screen off
+
+It is possible to turn the device screen off while mirroring on start with a
+command-line option:
+
+```bash
+scrcpy --turn-screen-off
+scrcpy -S
+```
+
+Or by pressing `Ctrl`+`o` at any time.
+
+To turn it back on, press `POWER` (or `Ctrl`+`p`).
+
+
+### Render expired frames
+
+By default, to minimize latency, _scrcpy_ always renders the last decoded frame
+available, and drops any previous one.
+
+To force the rendering of all frames (at a cost of a possible increased
+latency), use:
+
+```bash
+scrcpy --render-expired-frames
+```
+
+### Custom window title
+
+By default, the window title is the device model. It can be changed:
+
+```bash
+scrcpy --window-title 'My device'
+```
+
+
+### Forward audio
+
+Audio is not forwarded by _scrcpy_. Use [USBaudio] (Linux-only).

 ## Shortcuts

-In the following list, <kbd>MOD</kbd> is the shortcut modifier. By default, it's
-(left) <kbd>Alt</kbd> or (left) <kbd>Super</kbd>.
-
-It can be changed using `--shortcut-mod`. Possible keys are `lctrl`, `rctrl`,
-`lalt`, `ralt`, `lsuper` and `rsuper`. For example:
-
-```bash
-# use RCtrl for shortcuts
-scrcpy --shortcut-mod=rctrl
-
-# use either LCtrl+LAlt or LSuper for shortcuts
-scrcpy --shortcut-mod=lctrl+lalt,lsuper
-```
-
-_<kbd>[Super]</kbd> is typically the <kbd>Windows</kbd> or <kbd>Cmd</kbd> key._

 _¹Double-click on black borders to remove them._  
 _²Right-click turns the screen on if it was off, presses BACK otherwise._
-_³4th and 5th mouse buttons, if your mouse has them._  
-_⁴Only on Android >= 7._
-
-Shortcuts with repeated keys are executted by releasing and pressing the key a
-second time. For example, to execute "Expand settings panel":
-
- 1. Press and keep pressing <kbd>MOD</kbd>.
- 2. Then double-press <kbd>n</kbd>.
- 3. Finally, release <kbd>MOD</kbd>.
-
-All <kbd>Ctrl</kbd>+_key_ shortcuts are forwarded to the device, so they are
-handled by the active application.

-# scrcpy (v1.12.1)
-
-Esta aplicação fornece visualização e controle de dispositivos Android conectados via
-USB (ou [via TCP/IP][article-tcpip]). Não requer nenhum acesso root.
-Funciona em _GNU/Linux_, _Windows_ e _macOS_.
-
-![screenshot](assets/screenshot-debian-600.jpg)
-
-Foco em:
-
- - **leveza** (Nativo, mostra apenas a tela do dispositivo)
- - **performance** (30~60fps)
- - **qualidade** (1920×1080 ou acima)
- - **baixa latência** ([35~70ms][lowlatency])
- - **baixo tempo de inicialização** (~1 segundo para mostrar a primeira imagem)
- - **não intrusivo** (nada é deixado instalado no dispositivo)
-
-[lowlatency]: https://github.com/Genymobile/scrcpy/pull/646
-
-
-## Requisitos
-
-O Dispositivo Android requer pelo menos a API 21 (Android 5.0).
-
-
-Tenha certeza de ter [ativado a depuração USB][enable-adb] no(s) seu(s) dispositivo(s).
-
-[enable-adb]: https://developer.android.com/studio/command-line/adb.html#Enabling
-
-
-Em alguns dispositivos, você também precisará ativar [uma opção adicional][control] para controlá-lo usando o teclado e mouse.
-

-```
-
-Você também pode [compilar a aplicação manualmente][BUILD].
-
-
-## Executar
-
-Plugue um dispositivo Android e execute:
-
-```bash
-scrcpy
-```
-
-Também aceita argumentos de linha de comando, listados por:
-
-```bash
-scrcpy --help
-```
-
-## Funcionalidades
-
-### Configuração de captura
-
-#### Redução de tamanho
-
-Algumas vezes, é útil espelhar um dispositivo Android em uma resolução menor para
-aumentar performance.
-
-Para limitar ambos(largura e altura) para algum valor (ex: 1024):
-
-```bash
-scrcpy --max-size 1024
-scrcpy -m 1024  # versão reduzida
-```
-
-A outra dimensão é calculada para que a proporção do dispositivo seja preservada.
-Dessa forma, um dispositivo em 1920x1080 será espelhado em 1024x576.
-
-
-#### Mudanças no bit-rate
-
-O Padrão de bit-rate é 8 mbps. Para mudar o bitrate do vídeo (ex: para 2 Mbps):
-
-```bash
-scrcpy --bit-rate 2M
-scrcpy -b 2M  # versão reduzida
-```
-
-#### Limitar frame rates
-
-Em dispositivos com Android >= 10, a captura de frame rate pode ser limitada:
-
-```bash
-scrcpy --max-fps 15
-```
-
-#### Cortar
-
-A tela do dispositivo pode ser cortada para espelhar apenas uma parte da tela.
-
-Isso é útil por exemplo, ao espelhar apenas um olho do Oculus Go:
-
-```bash
-scrcpy --crop 1224:1440:0:0   # 1224x1440 no deslocamento (0,0)
-```
-
-Se `--max-size` também for especificado, redimensionar é aplicado após os cortes.
-
-
-### Gravando
-
-É possível gravar a tela enquanto ocorre o espelhamento:
-
-```bash
-scrcpy --record file.mp4
-scrcpy -r file.mkv
-```
-
-Para desativar o espelhamento durante a gravação:
-
-```bash
-scrcpy --no-display --record file.mp4
-scrcpy -Nr file.mkv
-# interrompe a gravação com Ctrl+C
-# Ctrl+C não encerrar propriamente no Windows, então desconecte o dispositivo
-```
-
-"Frames pulados" são gravados, mesmo que não sejam mostrado em tempo real (por motivos de performance).
-Frames tem seu _horário_ _carimbado_ no dispositivo, então [Variação de atraso nos pacotes] não impacta na gravação do arquivo.
-
-[Variação de atraso de pacote]: https://en.wikipedia.org/wiki/Packet_delay_variation
-
-
-### Conexão
-
-#### Wireless/Sem fio
-
-_Scrcpy_ usa `adb` para se comunicar com o dispositivo, e `adb` pode [conectar-se] à um dispositivo via TCP/IP:
-
-1. Conecte o dispositivo a mesma rede Wi-Fi do seu computador.
-2. Pegue o endereço de IP do seu dispositivo (Em Configurações → Sobre o Telefone → Status).
-3. Ative o adb via TCP/IP no seu dispositivo: `adb tcpip 5555`.
-4. Desplugue seu dispositivo.
-5. Conecte-se ao seu dispositivo: `adb connect DEVICE_IP:5555` _(substitua o `DEVICE_IP`)_.
-6. Execute `scrcpy` como de costume.
-
-Pode ser útil diminuir o bit-rate e a resolução:
-
-```bash
-scrcpy --bit-rate 2M --max-size 800
-scrcpy -b2M -m800  # versão reduzida
-```
-
-[conectar-se]: https://developer.android.com/studio/command-line/adb.html#wireless
-
-
-#### N-dispositivos
-
-Se alguns dispositivos estão listados em `adb devices`, você precisa especificar o _serial_:
-
-```bash
-scrcpy --serial 0123456789abcdef
-scrcpy -s 0123456789abcdef  # versão reduzida
-```
-
-Se o dispositivo está conectado via TCP/IP:
-
-```bash
-scrcpy --serial 192.168.0.1:5555
-scrcpy -s 192.168.0.1:5555  # versão reduzida
-```
-
-Você pode iniciar algumas instâncias do _scrcpy_ para alguns dispositivos.
-
-#### Conexão via SSH
-
-Para conectar-se à um dispositivo remoto, é possível se conectar um cliente local `adb`  à um servidor `adb` remoto (contanto que eles usem a mesma versão do protocolo _adb_):
-
-```bash
-adb kill-server    # encerra o servidor local na 5037
-ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
-# mantém isso aberto
-```
-
-De outro terminal:
-
-```bash
-scrcpy
-```
-
-Igual para conexões sem fio, pode ser útil reduzir a qualidade:
-
-```
-scrcpy -b2M -m800 --max-fps 15
-```
-
-### Configurações de Janela
-
-#### Título
-
-Por padrão, o título da janela é o modelo do dispositivo. Isto pode ser mudado:
-
-```bash
-scrcpy --window-title 'Meu dispositivo'
-```
-
-#### Posição e tamanho
-
-A posição e tamanho iniciais da janela podem ser especificados:
-
-```bash
-scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
-```
-
-#### Sem bordas
-
-Para desativar decorações da janela:
-
-```bash
-scrcpy --window-borderless
-```
-
-#### Sempre visível
-
-Para manter a janela do scrcpy sempre visível:
-
-```bash
-scrcpy --always-on-top
-```
-
-#### Tela cheia
-
-A aplicação pode ser iniciada diretamente em tela cheia:
-
-```bash
-scrcpy --fullscreen
-scrcpy -f  # versão reduzida
-```
-
-Tela cheia pode ser alternada dinamicamente com `Ctrl`+`f`.
-
-
-### Outras opções de espelhamento
-
-#### Apenas leitura
-
-Para desativar controles (tudo que possa interagir com o dispositivo: teclas de entrada, eventos de mouse, arrastar e soltar arquivos):
-
-```bash
-scrcpy --no-control
-scrcpy -n
-```
-
-#### Desligar a tela
-
-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 `Ctrl`+`o` durante qualquer momento.
-
-Para ligar novamente, pressione `POWER` (ou `Ctrl`+`p`).
-
-#### Frames expirados de renderização
-
-Por padrão, para minimizar a latência, _scrcpy_ sempre renderiza o último frame decodificado disponível e descarta o anterior.
-
-Para forçar a renderização de todos os frames ( com o custo de aumento de latência), use:
-
-```bash
-scrcpy --render-expired-frames
-```
-
-#### Mostrar toques
-
-Para apresentações, pode ser útil mostrar toques físicos(dispositivo físico).
-
-Android fornece esta funcionalidade nas _Opções do Desenvolvedor_.
-
-_Scrcpy_ fornece esta opção de ativar esta funcionalidade no início e desativar no encerramento:
-
-```bash
-scrcpy --show-touches
-scrcpy -t
-```
-
-Note que isto mostra apenas toques _físicos_ (com o dedo no dispositivo).
-
-
-### Controle de entrada
-
-#### Rotacionar a tela do dispositivo
-
-Pressione `Ctrl`+`r` para mudar entre os modos Retrato e Paisagem.
-
-Note que só será rotacionado se a aplicação em primeiro plano tiver suporte para o modo requisitado.
-
-#### Copiar-Colar
-
-É possível sincronizar áreas de transferência entre computador e o dispositivo,
-para ambas direções:
-
- - `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).
-
-#### Preferências de injeção de texto
-
-Existe dois tipos de [eventos][textevents] gerados ao digitar um texto:
- - _eventos de teclas_, sinalizando que a tecla foi pressionada ou solta;
- - _eventos de texto_, sinalizando que o texto foi inserido.
-
-Por padrão, letras são injetadas usando eventos de teclas, assim teclados comportam-se
-como esperado em jogos (normalmente para tecladas WASD)
-
-Mas isto pode [causar problemas][prefertext]. Se você encontrar tal problema,
-pode evitá-lo usando:
-
-```bash
-scrcpy --prefer-text
-```
-
-(mas isto vai quebrar o comportamento do teclado em jogos)

-
-
-### Transferência de arquivo
-
-#### Instalar APK
-
-Para instalar um APK, arraste e solte o arquivo APK(com extensão `.apk`) na janela _scrcpy_.
-
-Não existe feedback visual, um log é imprimido no console.
-
-
-#### Enviar arquivo para o dispositivo
-
-Para enviar um arquivo para o diretório `/sdcard/` no dispositivo, arraste e solte um arquivo não APK para a janela do
-_scrcpy_.
-
-Não existe feedback visual, um log é imprimido no console.
-
-O diretório alvo pode ser mudado ao iniciar:
-
-```bash
-scrcpy --push-target /sdcard/foo/bar/
-```
-
-
-### Encaminhamento de áudio
-
-Áudio não é encaminhando pelo _scrcpy_. Use [USBaudio] (Apenas linux).
-
-Também veja [issue #14].

-
-
-## 运行scrcpy
-
-用USB链接电脑和安卓设备，并执行：
-
-```bash
-scrcpy
-```
-
-支持带命令行参数执行，查看参数列表：
-
-```bash
-scrcpy --help
-```
-
-## 功能介绍
-
-### 画面设置
-
-#### 缩小分辨率
-
-有时候，将设备屏幕镜像分辨率降低可以有效地提升性能。
-
-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  # short version
-```
-
-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。
-
-
-#### 修改画面比特率
-
-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  # short version
-```
-
-#### 限制画面帧率
-
-画面的帧率可以通过下面的命令被限制：
-
-```bash
-scrcpy --max-fps 15
-```
-
-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
-
-设备画面可在裁切后进行镜像，以显示部分屏幕。
-
-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   # 1224x1440 at offset (0,0)
-```
-
-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。
-
-
-#### 锁定屏幕朝向
-
-
-可以使用如下命令锁定屏幕朝向：
-
-```bash
-scrcpy --lock-video-orientation 0   # 自然朝向
-scrcpy --lock-video-orientation 1   # 90° 逆时针旋转
-scrcpy --lock-video-orientation 2   # 180°
-scrcpy --lock-video-orientation 3   # 90° 顺时针旋转
-```
-
-该设定影响录制。
-
-
-### 屏幕录制
-
-可以在屏幕镜像的同时录制视频：
-
-```bash
-scrcpy --record file.mp4
-scrcpy -r file.mkv
-```
-
-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以停止录制
-```
-
-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。
-
-[包时延变化]: https://en.wikipedia.org/wiki/Packet_delay_variation
-
-
-### 连接方式
-
-#### 无线
-
-_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`。
-
-降低比特率和分辨率可能有助于性能：
-
-```bash
-scrcpy --bit-rate 2M --max-size 800
-scrcpy -b2M -m800  # short version
-```
-
-[连接]: https://developer.android.com/studio/command-line/adb.html#wireless
-
-
-#### 多设备
-
-如果多个设备在执行`adb devices`后被列出，您必须指定设备的 _序列号_ ：
-
-```bash
-scrcpy --serial 0123456789abcdef
-scrcpy -s 0123456789abcdef  # short version
-```
-
-如果设备是通过TCP/IP方式连接到电脑的：
-
-```bash
-scrcpy --serial 192.168.0.1:5555
-scrcpy -s 192.168.0.1:5555  # short version
-```
-
-您可以同时启动多个 _scrcpy_ 实例以同时显示多个设备的画面。
-
-#### 在设备连接时自动启动
-
-您可以使用 [AutoAdb]:
-
-```bash
-autoadb scrcpy -s '{}'
-```
-
-[AutoAdb]: https://github.com/rom1v/autoadb
-
-#### SSH 连接
-
-本地的 adb 可以远程连接到另一个 adb 服务器（假设两者的adb版本相同），来远程连接到设备：
-
-```bash
-adb kill-server    # 关闭本地5037端口上的adb服务器
-ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
-# 保持该窗口开启
-```
-
-从另一个终端：
-
-```bash
-scrcpy
-```
-
-为了避免启动远程端口转发，你可以强制启动一个转发连接（注意`-L`和`-R`的区别：
-
-```bash
-adb kill-server    # kill the local adb server on 5037
-ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 your_remote_computer
-# 保持该窗口开启
-```
-
-从另一个终端:
-
-```bash
-scrcpy --force-adb-forward
-```
-
-
-和无线网络连接类似，下列设置可能对改善性能有帮助：
-
-```
-scrcpy -b2M -m800 --max-fps 15
-```
-
-### 窗口设置
-
-#### 标题
-
-窗口的标题默认为设备型号。您可以通过如下命令修改它：
-
-```bash
-scrcpy --window-title 'My device'
-```
-
-#### 位置和大小
-
-您可以指定初始的窗口位置和大小：
-
-```bash
-scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
-```
-
-#### 无边框
-
-关闭边框：
-
-```bash
-scrcpy --window-borderless
-```
-
-#### 保持窗口在最前
-
-您可以通过如下命令保持窗口在最前面：
-
-```bash
-scrcpy --always-on-top
-```
-
-#### 全屏
-
-您可以通过如下命令直接全屏启动scrcpy：
-
-```bash
-scrcpy --fullscreen
-scrcpy -f  # short version
-```
-
-全屏状态可以通过<kbd>MOD</kbd>+<kbd>f</kbd>实时改变。
-
-#### 旋转
-
-通过如下命令，窗口可以旋转：
-
-```bash
-scrcpy --rotation 1
-```
-
-可选的值有：
- - `0`: 无旋转
- - `1`: 逆时针旋转90°
- - `2`: 旋转180°
- - `3`: 顺时针旋转90°
-
-这同样可以使用<kbd>MOD</kbd>+<kbd>←</kbd>
-_(左)_ 和 <kbd>MOD</kbd>+<kbd>→</kbd> _(右)_ 的快捷键实时更改。
-
-需要注意的是， _scrcpy_ 控制三个不同的朝向：
- - <kbd>MOD</kbd>+<kbd>r</kbd> 请求设备在竖屏和横屏之间切换（如果前台应用程序不支持所请求的朝向，可能会拒绝该请求）。
-
- - `--lock-video-orientation` 改变镜像的朝向（设备镜像到电脑的画面朝向）。这会影响录制。
-
- - `--rotation` （或<kbd>MOD</kbd>+<kbd>←</kbd>/<kbd>MOD</kbd>+<kbd>→</kbd>）
-   只旋转窗口的画面。这只影响显示，不影响录制。
-
-
-### 其他镜像设置
-
-#### 只读
-
-关闭电脑对设备的控制（如键盘输入、鼠标移动和文件传输）：
-
-```bash
-scrcpy --no-control
-scrcpy -n
-```
-
-#### 显示屏
-
-如果有多个显示屏可用，您可以选择特定显示屏进行镜像：
-
-```bash
-scrcpy --display 1
-```
-
-您可以通过如下命令找到显示屏的id：
-
-```
-adb shell dumpsys display   # 在回显中搜索“mDisplayId=”
-```
-
-第二显示屏可能只能在设备运行Android 10或以上的情况下被控制（它可能会在电脑上显示，但无法通过电脑操作）。
-
-
-#### 保持常亮
-
-防止设备在已连接的状态下休眠：
-
-```bash
-scrcpy --stay-awake
-scrcpy -w
-```
-
-程序关闭后，设备设置会恢复原样。
-
-
-#### 关闭设备屏幕
-
-在启动屏幕镜像时，可以通过如下命令关闭设备的屏幕：
-
-```bash
-scrcpy --turn-screen-off
-scrcpy -S
-```
-
-或者在需要的时候按<kbd>MOD</kbd>+<kbd>o</kbd>。
-
-要重新打开屏幕的话，需要按<kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd>.
-
-在Android上,`电源`按钮始终能把屏幕打开。
-
-为了方便，如果按下`电源`按钮的事件是通过 _scrcpy_ 发出的（通过点按鼠标右键或<kbd>MOD</kbd>+<kbd>p</kbd>），它会在短暂的延迟后将屏幕关闭。
-
-物理的`电源`按钮仍然能打开设备屏幕。
-
-同时，这项功能还能被用于防止设备休眠：
-
-```bash
-scrcpy --turn-screen-off --stay-awake
-scrcpy -Sw
-```
-
-
-#### 渲染超时帧
-
-为了降低延迟， _scrcpy_ 默认渲染解码成功的最近一帧，并跳过前面任意帧。
-
-强制渲染所有帧（可能导致延迟变高）：
-
-```bash
-scrcpy --render-expired-frames
-```
-
-#### 显示触摸
-
-在展示时，有些时候可能会用到显示触摸点这项功能（在设备上显示）。
-
-Android在 _开发者设置_ 中提供了这项功能。
-
-_Scrcpy_ 提供一个选项可以在启动时开启这项功能并在退出时恢复初始设置：
-
-```bash
-scrcpy --show-touches
-scrcpy -t
-```
-
-请注意这项功能只能显示 _物理_ 触摸（要用手在屏幕上触摸）。
-
-
-#### 关闭屏保
-
-_Scrcpy_ 不会默认关闭屏幕保护。
-
-关闭屏幕保护：
-
-```bash
-scrcpy --disable-screensaver
-```
-
-
-### 输入控制
-
-#### 旋转设备屏幕
-
-使用<kbd>MOD</kbd>+<kbd>r</kbd>以在竖屏和横屏模式之间切换。
-
-需要注意的是，只有在前台应用程序支持所要求的模式时，才会进行切换。
-
-#### 复制黏贴
-
-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> 复制
- - <kbd>Ctrl</kbd>+<kbd>x</kbd> 剪切
- - <kbd>Ctrl</kbd>+<kbd>v</kbd> 黏贴 （在电脑到设备的剪贴板同步完成之后）
-
-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_ 在<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。
-
-在这种情况下剪切复制黏贴（仅在Android >= 7时可用）：
- - <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`（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>可以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黏贴至设备（无论是通过<kbd>Ctrl</kbd>+<kbd>v</kbd>还是<kbd>MOD</kbd>+<kbd>v</kbd>）
-都需要将内容保存至设备的剪贴板。如此，任何一个应用程序都可以读取它。
-您应当避免将敏感内容通过这种方式传输（如密码）。
-
-
-#### 捏拉缩放
-
-模拟 “捏拉缩放”：<kbd>Ctrl</kbd>+_按住并移动鼠标_。
-
-更准确的说，您需要在按住<kbd>Ctrl</kbd>的同时按住并移动鼠标。
-在鼠标左键松开之后，光标的任何操作都会相对于屏幕的中央进行。
-
-具体来说， _scrcpy_ 使用“虚拟手指”以在相对于屏幕中央相反的位置产生触摸事件。
-
-
-#### 文字注入偏好
-
-打字的时候，系统会产生两种[事件][textevents]：
- - _按键事件_ ，代表一个按键被按下/松开。
- - _文本事件_ ，代表一个文本被输入。
-
-程序默认使用按键事件来输入字母。只有这样，键盘才会在游戏中正常运作（尤其WASD键）。
-
-但这也有可能[造成问题][prefertext]。如果您遇到了这样的问题，您可以通过下列操作避免它：
-
-```bash
-scrcpy --prefer-text

-
-
-#### 按键重复
-
-当你一直按着一个按键不放时，程序默认产生多个按键事件。
-在某些游戏中这可能会导致性能问题。
-
-避免转发重复按键事件：
-
-```bash
-scrcpy --no-key-repeat
-```
-
-
-### 文件传输
-
-#### 安装APK
-
-如果您要要安装APK，请拖放APK文件（文件名以`.apk`结尾）到 _scrcpy_ 窗口。
-
-该操作在屏幕上不会出现任何变化，而会在控制台输出一条日志。
-
-
-#### 将文件推送至设备
-
-如果您要推送文件到设备的 `/sdcard/`，请拖放文件至（不能是APK文件）_scrcpy_ 窗口。
-
-该操作没有可见的响应，只会在控制台输出日志。
-
-在启动时可以修改目标目录：
-
-```bash
-scrcpy --push-target /sdcard/foo/bar/
-```
-
-
-### 音频转发
-
-_scrcpy_ 不支持音频。请使用 [sndcpy].
-
-另外请阅读 [issue #14]。

-[issue #14]: https://github.com/Genymobile/scrcpy/issues/14
-
-
-## 热键
-
-在下列表格中, <kbd>MOD</kbd> 是热键的修饰键。
-默认是（左）<kbd>Alt</kbd>或者（左）<kbd>Super</kbd>。
-
-您可以使用 `--shortcut-mod`后缀来修改它。可选的按键有`lctrl`、`rctrl`、
-`lalt`、`ralt`、`lsuper`和`rsuper`。如下例：
-
-```bash
-# 使用右侧的Ctrl键
-scrcpy --shortcut-mod=rctrl
-
-# 使用左侧的Ctrl键、Alt键或Super键
-scrcpy --shortcut-mod=lctrl+lalt,lsuper
-```
-
-_一般来说，<kbd>[Super]</kbd>就是<kbd>Windows</kbd>或者<kbd>Cmd</kbd>。_
-

-## 自定义路径
-
-为了使用您想使用的 _adb_ ，您可以在环境变量
-`ADB`中设置它的路径：
-
-    ADB=/path/to/adb scrcpy
-
-如果需要覆盖`scrcpy-server`的路径，您可以在
-`SCRCPY_SERVER_PATH`中设置它。

-## 为什么叫 _scrcpy_ ？
-
-一个同事让我找出一个和[gnirehtet]一样难以发音的名字。
-
-[`strcpy`] 可以复制**str**ing； `scrcpy` 可以复制**scr**een。

-# scrcpy (v1.15)
-
-Scrcpy 可以透過 USB、或是 [TCP/IP][article-tcpip] 來顯示或控制 Android 裝置。且 scrcpy 不需要 _root_ 權限。
-
-Scrcpy 目前支援 _GNU/Linux_、_Windows_ 和 _macOS_。
-
-![screenshot](assets/screenshot-debian-600.jpg)
-
-特色:
-
- - **輕量** (只顯示裝置螢幕)
- - **效能** (30~60fps)
- - **品質** (1920×1080 或更高)
- - **低延遲** ([35~70ms][lowlatency])
- - **快速啟動** (~1 秒就可以顯示第一個畫面)
- - **非侵入性** (不安裝、留下任何東西在裝置上)
-
-[lowlatency]: https://github.com/Genymobile/scrcpy/pull/646
-
-
-## 需求
-
-Android 裝置必須是 API 21+ (Android 5.0+)。
-
-請確認裝置上的 [adb 偵錯 (通常位於開發者模式內)][enable-adb] 已啟用。
-
-[enable-adb]: https://developer.android.com/studio/command-line/adb.html#Enabling
-
-
-在部分的裝置上，你也必須啟用[特定的額外選項][control]才能使用鍵盤和滑鼠控制。
-

-brew cask install android-platform-tools
-```
-
-你也可以自己[編譯 _Scrcpy_][BUILD]。
-
-
-## 執行
-
-將電腦和你的 Android 裝置連線，然後執行:
-
-```bash
-scrcpy
-```
-
-_Scrcpy_ 可以接受命令列參數。輸入下列指令就可以瀏覽可以使用的命令列參數:
-
-```bash
-scrcpy --help
-```
-
-
-## 功能
-
-> 以下說明中，有關快捷鍵的說明可能會出現 <kbd>MOD</kbd> 按鈕。相關說明請參見[快捷鍵]內的說明。
-
-[快捷鍵]: #快捷鍵
-
-### 畫面擷取
-
-#### 縮小尺寸
-
-使用比較低的解析度來投放 Android 裝置在某些情況可以提升效能。
-
-限制寬和高的最大值(例如: 1024):
-
-```bash
-scrcpy --max-size 1024
-scrcpy -m 1024  # 縮短版本
-```
-
-比較小的參數會根據螢幕比例重新計算。
-根據上面的範例，1920x1080 會被縮小成 1024x576。
-
-
-#### 更改 bit-rate
-
-預設的 bit-rate 是 8 Mbps。如果要更改 bit-rate (例如: 2 Mbps):
-
-```bash
-scrcpy --bit-rate 2M
-scrcpy -b 2M  # 縮短版本
-```
-
-#### 限制 FPS
-
-限制畫面最高的 FPS:
-
-```bash
-scrcpy --max-fps 15
-```
-
-僅在 Android 10 後正式支援，不過也有可能可以在 Android 10 以前的版本使用。
-
-#### 裁切
-
-裝置的螢幕可以裁切。如此一來，鏡像出來的螢幕就只會是原本的一部份。
-
-假如只要鏡像 Oculus Go 的其中一隻眼睛:
-
-```bash
-scrcpy --crop 1224:1440:0:0   # 位於 (0,0)，大小1224x1440
-```
-
-如果 `--max-size` 也有指定的話，裁切後才會縮放。
-
-
-#### 鎖定影像方向
-
-
-如果要鎖定鏡像影像方向:
-
-```bash
-scrcpy --lock-video-orientation 0   # 原本的方向
-scrcpy --lock-video-orientation 1   # 逆轉 90°
-scrcpy --lock-video-orientation 2   # 180°
-scrcpy --lock-video-orientation 3   # 順轉 90°
-```
-
-這會影響錄影結果的影像方向。
-
-
-### 錄影
-
-鏡像投放螢幕的同時也可以錄影:
-
-```bash
-scrcpy --record file.mp4
-scrcpy -r file.mkv
-```
-
-如果只要錄影，不要投放螢幕鏡像的話:
-
-```bash
-scrcpy --no-display --record file.mp4
-scrcpy -Nr file.mkv
-# 用 Ctrl+C 停止錄影
-```
-
-就算有些幀為了效能而被跳過，它們還是一樣會被錄製。
-
-裝置上的每一幀都有時間戳記，所以 [封包延遲 (Packet Delay Variation, PDV)][packet delay variation] 並不會影響錄影的檔案。
-
-[packet delay variation]: https://en.wikipedia.org/wiki/Packet_delay_variation
-
-
-### 連線
-
-#### 無線
-
-_Scrcpy_ 利用 `adb` 和裝置通訊，而 `adb` 可以[透過 TCP/IP 連結][connect]:
-
-1. 讓電腦和裝置連到同一個 Wi-Fi。
-2. 獲取手機的 IP 位址(設定 → 關於手機 → 狀態).
-3. 啟用裝置上的 `adb over TCP/IP`: `adb tcpip 5555`.
-4. 拔掉裝置上的線。
-5. 透過 TCP/IP 連接裝置: `adb connect DEVICE_IP:5555` _(把 `DEVICE_IP` 換成裝置的IP位址)_.
-6. 和平常一樣執行 `scrcpy`。
-
-如果效能太差，可以降低 bit-rate 和解析度:
-
-```bash
-scrcpy --bit-rate 2M --max-size 800
-scrcpy -b2M -m800  # 縮短版本
-```
-
-[connect]: https://developer.android.com/studio/command-line/adb.html#wireless
-
-
-#### 多裝置
-
-如果 `adb devices` 內有多個裝置，則必須附上 _serial_:
-
-```bash
-scrcpy --serial 0123456789abcdef
-scrcpy -s 0123456789abcdef  # 縮短版本
-```
-
-如果裝置是透過 TCP/IP 連線:
-
-```bash
-scrcpy --serial 192.168.0.1:5555
-scrcpy -s 192.168.0.1:5555  # 縮短版本
-```
-
-你可以啟用復數個對應不同裝置的 _scrcpy_。
-
-#### 裝置連結後自動啟動
-
-你可以使用 [AutoAdb]:
-
-```bash
-autoadb scrcpy -s '{}'
-```
-
-[AutoAdb]: https://github.com/rom1v/autoadb
-
-#### SSH tunnel
-
-本地的 `adb` 可以連接到遠端的 `adb` 伺服器(假設兩者使用相同版本的 _adb_ 通訊協定)，以連接到遠端裝置:
-
-```bash
-adb kill-server    # 停止在 Port 5037 的本地 adb 伺服
-ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
-# 保持開啟
-```
-
-從另外一個終端機:
-
-```bash
-scrcpy
-```
-
-如果要避免啟用 remote port forwarding，你可以強制它使用 forward connection (注意 `-L` 和 `-R` 的差別):
-
-```bash
-adb kill-server    # 停止在 Port 5037 的本地 adb 伺服
-ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 your_remote_computer
-# 保持開啟
-```
-
-從另外一個終端機:
-
-```bash
-scrcpy --force-adb-forward
-```
-
-
-和無線連接一樣，有時候降低品質會比較好:
-
-```
-scrcpy -b2M -m800 --max-fps 15
-```
-
-### 視窗調整
-
-#### 標題
-
-預設標題是裝置的型號，不過可以透過以下方式修改:
-
-```bash
-scrcpy --window-title 'My device'
-```
-
-#### 位置 & 大小
-
-初始的視窗位置和大小也可以指定:
-
-```bash
-scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
-```
-
-#### 無邊框
-
-如果要停用視窗裝飾:
-
-```bash
-scrcpy --window-borderless
-```
-
-#### 保持最上層
-
-如果要保持 `scrcpy` 的視窗在最上層:
-
-```bash
-scrcpy --always-on-top
-```
-
-#### 全螢幕
-
-這個軟體可以直接在全螢幕模式下起動:
-
-```bash
-scrcpy --fullscreen
-scrcpy -f  # 縮短版本
-```
-
-全螢幕可以使用 <kbd>MOD</kbd>+<kbd>f</kbd> 開關。
-
-#### 旋轉
-
-視窗可以旋轉:
-
-```bash
-scrcpy --rotation 1
-```
-
-可用的數值:
- - `0`: 不旋轉
- - `1`: 90 度**逆**轉
- - `2`: 180 度
- - `3`: 90 度**順**轉
-
-旋轉方向也可以使用 <kbd>MOD</kbd>+<kbd>←</kbd> _(左方向鍵)_ 和 <kbd>MOD</kbd>+<kbd>→</kbd> _(右方向鍵)_ 調整。
-
-_scrcpy_ 有 3 種不同的旋轉:
- - <kbd>MOD</kbd>+<kbd>r</kbd> 要求裝置在垂直、水平之間旋轉 (目前運行中的 App 有可能會因為不支援而拒絕)。
- - `--lock-video-orientation` 修改鏡像的方向 (裝置傳給電腦的影像)。這會影響錄影結果的影像方向。
- - `--rotation` (或是 <kbd>MOD</kbd>+<kbd>←</kbd> / <kbd>MOD</kbd>+<kbd>→</kbd>) 只旋轉視窗的內容。這只會影響鏡像結果，不會影響錄影結果。
-
-
-### 其他鏡像選項
-
-#### 唯讀
-
-停用所有控制，包含鍵盤輸入、滑鼠事件、拖放檔案:
-
-```bash
-scrcpy --no-control
-scrcpy -n
-```
-
-#### 顯示螢幕
-
-如果裝置有複數個螢幕，可以指定要鏡像哪個螢幕:
-
-```bash
-scrcpy --display 1
-```
-
-可以透過下列指令獲取螢幕 ID:
-
-```
-adb shell dumpsys display   # 找輸出結果中的 "mDisplayId="
-```
-
-第二螢幕只有在 Android 10+ 時可以控制。如果不是 Android 10+，螢幕就會在唯讀狀態下投放。
-
-
-#### 保持清醒
-
-如果要避免裝置在連接狀態下進入睡眠:
-
-```bash
-scrcpy --stay-awake
-scrcpy -w
-```
-
-_scrcpy_ 關閉後就會回復成原本的設定。
-
-
-#### 關閉螢幕
-
-鏡像開始時，可以要求裝置關閉螢幕:
-
-```bash
-scrcpy --turn-screen-off
-scrcpy -S
-```
-
-或是在任何時候輸入 <kbd>MOD</kbd>+<kbd>o</kbd>。
-
-如果要開啟螢幕，輸入 <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd>。
-
-在 Android 上，`POWER` 按鈕總是開啟螢幕。
-
-為了方便，如果 `POWER` 是透過 scrcpy 轉送 (右鍵 或 <kbd>MOD</kbd>+<kbd>p</kbd>)的話，螢幕將會在短暫的延遲後關閉。
-
-實際在手機上的 `POWER` 還是會開啟螢幕。
-
-防止裝置進入睡眠狀態:
-
-```bash
-scrcpy --turn-screen-off --stay-awake
-scrcpy -Sw
-```
-
-
-#### 顯示過期的幀
-
-為了降低延遲， _scrcpy_ 預設只會顯示最後解碼的幀，並且拋棄所有在這之前的幀。
-
-如果要強制顯示所有的幀 (有可能會拉高延遲)，輸入:
-
-```bash
-scrcpy --render-expired-frames
-```
-
-#### 顯示觸控點
-
-對於要報告的人來說，顯示裝置上的實際觸控點有時候是有幫助的。
-
-Android 在_開發者選項_中有提供這個功能。
-
-_Scrcpy_ 可以在啟動時啟用這個功能，並且在停止後恢復成原本的設定:
-
-```bash
-scrcpy --show-touches
-scrcpy -t
-```
-
-這個選項只會顯示**實際觸碰在裝置上的觸碰點**。
-
-
-### 輸入控制
-
-
-#### 旋轉裝置螢幕
-
-輸入 <kbd>MOD</kbd>+<kbd>r</kbd> 以在垂直、水平之間切換。
-
-如果使用中的程式不支援，則不會切換。
-
-
-#### 複製/貼上
-
-如果 Android 剪貼簿上的內容有任何更動，電腦的剪貼簿也會一起更動。
-
-任何與 <kbd>Ctrl</kbd> 相關的快捷鍵事件都會轉送到裝置上。特別來說:
- - <kbd>Ctrl</kbd>+<kbd>c</kbd> 通常是複製
- - <kbd>Ctrl</kbd>+<kbd>x</kbd> 通常是剪下
- - <kbd>Ctrl</kbd>+<kbd>v</kbd> 通常是貼上 (在電腦的剪貼簿與裝置上的剪貼簿同步之後)
-
-這些跟你通常預期的行為一樣。
-
-但是，實際上的行為是根據目前運行中的應用程式而定。
-
-舉例來說， _Termux_ 在收到 <kbd>Ctrl</kbd>+<kbd>c</kbd> 後，會傳送 SIGINT；而 _K-9 Mail_ 則是建立新訊息。
-
-如果在這情況下，要剪下、複製或貼上 (只有在Android 7+時才支援):
- - <kbd>MOD</kbd>+<kbd>c</kbd> 注入 `複製`
- - <kbd>MOD</kbd>+<kbd>x</kbd> 注入 `剪下`
- - <kbd>MOD</kbd>+<kbd>v</kbd> 注入 `貼上` (在電腦的剪貼簿與裝置上的剪貼簿同步之後)
-
-另外，<kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> 則是以一連串的按鍵事件貼上電腦剪貼簿中的內容。當元件不允許文字貼上 (例如 _Termux_) 時，這就很有用。不過，這在非 ASCII 內容上就無法使用。
-
-**警告:** 貼上電腦的剪貼簿內容 (無論是從 <kbd>Ctrl</kbd>+<kbd>v</kbd> 或 <kbd>MOD</kbd>+<kbd>v</kbd>) 時，會複製剪貼簿中的內容至裝置的剪貼簿上。這會讓所有 Android 程式讀取剪貼簿的內容。請避免貼上任何敏感內容 (像是密碼)。
-
-
-#### 文字輸入偏好
-
-輸入文字時，有兩種[事件][textevents]會被觸發:
- - _鍵盤事件 (key events)_，代表有一個按鍵被按下或放開
- - _文字事件 (text events)_，代表有一個文字被輸入
-
-預設上，文字是被以鍵盤事件 (key events) 輸入的，所以鍵盤和遊戲內所預期的一樣 (通常是指 WASD)。
-
-但是這可能造成[一些問題][prefertext]。如果在這輸入這方面遇到了問題，你可以試試:
-
-```bash
-scrcpy --prefer-text
-```
-
-(不過遊戲內鍵盤就會不可用)
-

-[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
-
-
-#### 重複輸入
-
-通常來說，長時間按住一個按鍵會重複觸發按鍵事件。這會在一些遊戲中造成效能問題，而且這個重複的按鍵事件是沒有意義的。
-
-如果不要轉送這些重複的按鍵事件:
-
-```bash
-scrcpy --no-key-repeat
-```
-
-
-### 檔案
-
-#### 安裝 APK
-
-如果要安裝 APK ，拖放一個 APK 檔案 (以 `.apk` 為副檔名) 到 _scrcpy_ 的視窗上。
-
-視窗上不會有任何反饋；結果會顯示在命令列中。
-
-
-#### 推送檔案至裝置
-
-如果要推送檔案到裝置上的 `/sdcard/` ，拖放一個非 APK 檔案 (**不**以 `.apk` 為副檔名) 到 _scrcpy_ 的視窗上。
-
-視窗上不會有任何反饋；結果會顯示在命令列中。
-
-推送檔案的目標路徑可以在啟動時指定:
-
-```bash
-scrcpy --push-target /sdcard/foo/bar/
-```
-
-
-### 音訊轉送
-
-_scrcpy_ **不**轉送音訊。請使用 [sndcpy]。另外，參見 [issue #14]。

-[issue #14]: https://github.com/Genymobile/scrcpy/issues/14
-
-
-## 快捷鍵
-
-在以下的清單中，<kbd>MOD</kbd> 是快捷鍵的特殊按鍵。通常來說，這個按鍵是 (左) <kbd>Alt</kbd> 或是 (左) <kbd>Super</kbd>。
-
-這個是可以使用 `--shortcut-mod` 更改的。可以用的選項有:
- `lctrl`: 左邊的 <kbd>Ctrl</kbd>
- `rctrl`: 右邊的 <kbd>Ctrl</kbd>
- `lalt`: 左邊的 <kbd>Alt</kbd>
- `ralt`: 右邊的 <kbd>Alt</kbd>
- `lsuper`: 左邊的 <kbd>Super</kbd>
- `rsuper`: 右邊的 <kbd>Super</kbd>
-
-```bash
-# 以 右邊的 Ctrl 為快捷鍵特殊按鍵
-scrcpy --shortcut-mod=rctrl
-
-# 以 左邊的 Ctrl 和左邊的 Alt 或是 左邊的 Super 為快捷鍵特殊按鍵
-scrcpy --shortcut-mod=lctrl+lalt,lsuper
-```
-
-_<kbd>[Super]</kbd> 通常是 <kbd>Windows</kbd> 或 <kbd>Cmd</kbd> 鍵。_

-
-_¹在黑邊框上雙擊以移除它們。_  
-_²右鍵會返回。如果螢幕是關閉狀態，則會打開螢幕。_  
-_³只支援 Android 7+。_
-
-所有 <kbd>Ctrl</kbd>+_按鍵_ 快捷鍵都會傳送到裝置上，所以它們是由目前運作的應用程式處理的。
-
-
-## 自訂路徑
-
-如果要使用特定的 _adb_ ，將它設定到環境變數中的 `ADB`:
-
-    ADB=/path/to/adb scrcpy
-
-如果要覆寫 `scrcpy-server` 檔案的路徑，則將路徑設定到環境變數中的 `SCRCPY_SERVER_PATH`。

-.TH "scrcpy" "1"
-.SH NAME
-scrcpy \- Display and control your Android device
-
-
-.SH SYNOPSIS
-.B scrcpy
-.RI [ options ]
-
-
-.SH DESCRIPTION
-.B scrcpy
-provides display and control of Android devices connected on USB (or over TCP/IP). It does not require any root access.
-
-
-.SH OPTIONS
-
-.TP
-.B \-\-always\-on\-top
-Make scrcpy window always on top (above other windows).
-
-.TP
-.BI "\-b, \-\-bit\-rate " value
-Encode the video at the given bit\-rate, expressed in bits/s. Unit suffixes are supported: '\fBK\fR' (x1000) and '\fBM\fR' (x1000000).
-
-Default is 8000000.
-
-.TP
-.BI "\-\-codec\-options " key[:type]=value[,...]
-Set a list of comma-separated key:type=value options for the device encoder.
-
-The possible values for 'type' are 'int' (default), 'long', 'float' and 'string'.
-
-The list of possible codec options is available in the Android documentation
-.UR https://d.android.com/reference/android/media/MediaFormat
-.UE .
-
-.TP
-.BI "\-\-crop " width\fR:\fIheight\fR:\fIx\fR:\fIy
-Crop the device screen on the server.
-
-The values are expressed in the device natural orientation (typically, portrait for a phone, landscape for a tablet). Any
-.B \-\-max\-size
-value is computed on the cropped size.
-
-.TP
-.BI "\-\-disable-screensaver"
-Disable screensaver while scrcpy is running.
-
-.TP
-.BI "\-\-display " id
-Specify the display id to mirror.
-
-The list of possible display ids can be listed by "adb shell dumpsys display"
-(search "mDisplayId=" in the output).
-
-Default is 0.
-
-.TP
-.BI "\-\-encoder " name
-Use a specific MediaCodec encoder (must be a H.264 encoder).
-
-.TP
-.B \-\-force\-adb\-forward
-Do not attempt to use "adb reverse" to connect to the device.
-
-.TP
-.B \-\-forward\-all\-clicks
-By default, right-click triggers BACK (or POWER on) and middle-click triggers HOME. This option disables these shortcuts and forward the clicks to the device instead.
-
-.TP
-.B \-f, \-\-fullscreen
-Start in fullscreen.
-
-.TP
-.B \-h, \-\-help
-Print this help.
-
-.TP
-.B \-\-legacy\-paste
-Inject computer clipboard text as a sequence of key events on Ctrl+v (like MOD+Shift+v).
-
-This is a workaround for some devices not behaving as expected when setting the device clipboard programmatically.
-
-.TP
-.BI "\-\-lock\-video\-orientation " [value]
-Lock video orientation to \fIvalue\fR. Possible values are "unlocked", "initial" (locked to the initial orientation), 0, 1, 2 and 3. Natural device orientation is 0, and each increment adds a 90 degrees otation counterclockwise.
-
-Default is "unlocked".
-
-Passing the option without argument is equivalent to passing "initial".
-
-.TP
-.BI "\-\-max\-fps " value
-Limit the framerate of screen capture (officially supported since Android 10, but may work on earlier versions).
-
-.TP
-.BI "\-m, \-\-max\-size " value
-Limit both the width and height of the video to \fIvalue\fR. The other dimension is computed so that the device aspect\-ratio is preserved.
-
-Default is 0 (unlimited).
-
-.TP
-.B \-n, \-\-no\-control
-Disable device control (mirror the device in read\-only).
-
-.TP
-.B \-N, \-\-no\-display
-Do not display device (only when screen recording is enabled).
-
-.TP
-.B \-\-no\-key\-repeat
-Do not forward repeated key events when a key is held down.
-
-.TP
-.B \-\-no\-mipmaps
-If the renderer is OpenGL 3.0+ or OpenGL ES 2.0+, then mipmaps are automatically generated to improve downscaling quality. This option disables the generation of mipmaps.
-
-.TP
-.BI "\-p, \-\-port " port[:port]
-Set the TCP port (range) used by the client to listen.
-
-Default is 27183:27199.
-
-.TP
-.B \-\-prefer\-text
-Inject alpha characters and space as text events instead of key events.
