+# 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.

+
+
+### 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 [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/
+```
+

+
+[`strcpy`] copia uma **str**ing; `scrcpy` copia uma **scr**een.
