-#### v4l2loopback
-
-Su Linux è possibile inviare il flusso video ad un dispositivo v4l2 loopback, cosicchè un dispositivo Android possa essere aperto come una webcam da qualsiasi strumento compatibile con v4l2.
-
-Il modulo `v4l2loopback` deve essere installato:
-
-```bash
-sudo apt install v4l2loopback-dkms
-```
-
-Per creare un dispositvo v4l2:
-
-```bash
-sudo modprobe v4l2loopback
-```
-
-Questo creerà un nuovo dispositivo video in `/dev/videoN` dove `N` è un intero (più [opzioni](https://github.com/umlaeute/v4l2loopback#options) sono disponibili per crere più dispositivi o dispositivi con ID specifici).
-
-Per elencare i dispositvi attivati:
-
-```bash
-# necessita del pacchetto v4l-utils
-v4l2-ctl --list-devices
-
-# semplice ma potrebbe essere sufficiente
-ls /dev/video*
-```
-
-Per avviare scrcpy utilizzando un v4l2 sink:
-
-```bash
-scrcpy --v4l2-sink=/dev/videoN
-scrcpy --v4l2-sink=/dev/videoN --no-display  # disabilita la finestra di trasmissione
-scrcpy --v4l2-sink=/dev/videoN -N            # versione corta
-```
-
-(sostituisci `N` con l'ID del dispositivo, controlla con `ls /dev/video*`)
-
-Una volta abilitato, puoi aprire il tuo flusso video con uno strumento compatibile con v4l2:
-
-```bash
-ffplay -i /dev/videoN
-vlc v4l2:///dev/videoN   # VLC potrebbe aggiungere del ritardo per il buffer
-```
-
-Per esempio potresti catturare il video in [OBS].
-
-[OBS]: https://obsproject.com/
-
-
-#### Buffering
-
-È possibile aggiungere del buffer. Questo aumenta la latenza ma riduce il jitter (vedi [#2464]).
-
-[#2464]: https://github.com/Genymobile/scrcpy/issues/2464
-
-L'opzione è disponibile per il buffer della visualizzazione:
-
-```bash
-scrcpy --display-buffer=50  # aggiungi 50 ms di buffer per la visualizzazione
-```
-
-e per il V4L2 sink:
-

-scrcpy --v4l2-buffer=500    #  aggiungi 50 ms di buffer per il v4l2 sink

+#### Wireless

 _Scrcpy_ uses `adb` to communicate with the device, and `adb` can [connect] to a
-device over TCP/IP. The device must be connected on the same network as the
-computer.
-
-##### Automatic
-
-An option `--tcpip` allows to configure the connection automatically. There are
-two variants.
-
-If the device (accessible at 192.168.1.1 in this example) already listens on a
-port (typically 5555) for incoming adb connections, then run:
-
-```bash
-scrcpy --tcpip=192.168.1.1       # default port is 5555
-scrcpy --tcpip=192.168.1.1:5555
-```
-
-If adb TCP/IP mode is disabled on the device (or if you don't know the IP
-address), connect the device over USB, then run:

-
-在 Linux 上，可以将视频流发送至 v4l2 回环 (loopback) 设备，因此可以使用任何 v4l2 工具像摄像头一样打开安卓设备。

-```bash
-sudo apt install v4l2loopback-dkms

-
-创建一个 v4l2 设备：

-```bash
-# 需要 v4l-utils 包

-使用一个 v4l2 漏开启 scrcpy：
-
-```bash
-scrcpy --v4l2-sink=/dev/videoN
-scrcpy --v4l2-sink=/dev/videoN --no-display  # 禁用窗口镜像
-scrcpy --v4l2-sink=/dev/videoN -N            # 简写
-```
-
-(将 `N` 替换为设备 ID，使用 `ls /dev/video*` 命令查看)
-
-启用之后，可以使用 v4l2 工具打开视频流：
-
-```bash
-ffplay -i /dev/videoN
-vlc v4l2:///dev/videoN   # VLC 可能存在一些缓冲延迟
-```
-

-/* The representation of input events in scrcpy is very close to the SDL API,
- * for simplicity.
- *
- * This scrcpy input events API is designed to be consumed by input event
- * processors (sc_key_processor and sc_mouse_processor, see app/src/trait/).
- *
- * One major semantic difference between SDL input events and scrcpy input
- * events is their frame of reference (for mouse and touch events): SDL events
- * coordinates are expressed in SDL window coordinates (the visible UI), while
- * scrcpy events are expressed in device frame coordinates.
- *
- * In particular, the window may be visually scaled or rotated (with --rotation
- * or MOD+Left/Right), but this does not impact scrcpy input events (contrary
- * to SDL input events). This allows to abstract these display details from the
- * input event processors (and to make them independent from the "screen").
- *
- * For many enums below, the values are purposely the same as the SDL
- * constants (though not all SDL values are represented), so that the
- * implementation to convert from the SDL version to the scrcpy version is
- * straightforward.
- *
- * In practice, there are 3 levels of input events:
- *  1. SDL input events (as received from SDL)
- *  2. scrcpy input events (this API)
- *  3. the key/mouse processors input events (Android API or HID events)
- *
- * An input event is first received (1), then (if accepted) converted to an
- * scrcpy input event (2), then submitted to the relevant key/mouse processor,
- * which (if accepted) is converted to an Android event (to be sent to the
- * server) or to an HID event (to be sent over USB/AOA directly).
