# scrcpy (v1.12.1)
Esta aplicação fornece visualização e controle de dispositivos Androids 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.

```
[Scoop]: https://scoop.sh
Você também pode [bui]
You can also [buildar a aplicação manualmente][BUILD].
### macOS
A aplicação está disponível em [Homebrew]. Apenas a instale:
[Homebrew]: https://brew.sh/
```bash
brew install scrcpy
```
Você precisa do `adb`, acessível através do seu `PATH`. Se você ainda não o tem:
```bash
brew cask install android-platform-tools
```
Você também pode [buildar 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 [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).
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`)_.
6. Run `scrcpy` as usual.
It may be useful to decrease the bit-rate and the definition:
```bash
scrcpy --bit-rate 2M --max-size 800
scrcpy -b2M -m800 # short version
```
[connect]: https://developer.android.com/studio/command-line/adb.html#wireless
#### Multi-devices
If several devices are listed in `adb devices`, you must specify the _serial_:
```bash
scrcpy --serial 0123456789abcdef
scrcpy -s 0123456789abcdef # short version
```
If the device is connected over TCP/IP:
```bash
scrcpy --serial 192.168.0.1:5555
scrcpy -s 192.168.0.1:5555 # short version
```
You can start several instances of _scrcpy_ for several devices.
#### 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
```
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
```
#### Fullscreen
The app may be started directly in fullscreen:
```bash
scrcpy --fullscreen
scrcpy -f # short version
```
Fullscreen can then be toggled dynamically with `Ctrl`+`f`.
### 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
```
#### 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
```
#### Show touches
For presentations, it may be useful to show physical touches (on the physical
device).
Android provides this feature in _Developers options_.
_Scrcpy_ provides an option to enable this feature on start and disable on exit:
```bash
scrcpy --show-touches
scrcpy -t
```
Note that it only shows _physical_ touches (with the finger on the device).
### Input control
#### Rotate device screen
Press `Ctrl`+`r` to switch between portrait and landscape modes.
Note that it rotates only if the application in foreground supports the
requested orientation.
#### Copy-paste
It is possible to synchronize clipboards between the computer and the device, in
both directions:
- `Ctrl`+`c` copies the device clipboard to the computer clipboard;
- `Ctrl`+`Shift`+`v` copies the computer clipboard to the device clipboard;
- `Ctrl`+`v` _pastes_ the computer clipboard as a sequence of text events (but
breaks non-ASCII characters).
#### 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)

[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
### File drop
#### Install APK
To install an APK, drag & drop an APK file (ending with `.apk`) to the _scrcpy_
window.
There is no visual feedback, a log is printed to the console.
#### Push file to device
To push a file to `/sdcard/` on the device, drag & drop a (non-APK) file to the
_scrcpy_ window.
There is no visual feedback, a log is printed to the console.
The target directory can be changed on start:
```bash
scrcpy --push-target /sdcard/foo/bar/
```
### Audio forwarding
Audio is not forwarded by _scrcpy_. Use [USBaudio] (Linux-only).
Also see [issue #14].

## Custom paths
To use a specific _adb_ binary, configure its path in the environment variable
`ADB`:
ADB=/path/to/adb scrcpy
To override the path of the `scrcpy-server` file, configure its path in
`SCRCPY_SERVER_PATH`.

## Why _scrcpy_?
A colleague challenged me to find a name as unpronounceable as [gnirehtet].
[`strcpy`] copies a **str**ing; `scrcpy` copies a **scr**een.
