一.原理(Summary)

后端用scrcpy_server.jar获取手机h264流, 传输通过websocket(django高效异步),前端broardway,webcodecs播放视频流并捕获鼠标事件完成操控。 电脑先配置好adb,手机设备打开usb调试并连接项目所在的电脑主机, 经测试在usb2.0, 720X336分辨率,800k比特率,25帧,本地浏览器延迟大概为60ms左右。
Backend scrcpy_server.jar grab android-device screen-raw-h264 data.
Transmission based on websocket (Django efficiently asynchronous coroutine).
Frontend broardway.js play screen-raw-h264 data, capture mouse`s event to control. We test in local browser[usb2.0, 720x336, 800kbit/s, 25fps] delay average 60ms.

二.运行(Usage):

Make sure adb server started and android-device(in Developer Mode) has connected to adb server.
adb devices in command line can list connected device.

1.运行

  • download project
  • Install(项目升级时需要删除目录下db.sqlite文件,重新install)
    pip install -r requirements.txt
    python init.py
  • Run(Visit http://127.0.0.1:8000/admin)
    uvicorn django_scrcpy.asgi:application --host 0.0.0.0 --port 8000 --workers 4

2.docker运行

  • run

    • linux
      docker run -it --name django_scrcpy --net=host -v some_dir:/usr/src/app/media -e DJANGO_SCRCPY_PORT=8000 lim1942/django_scrcpy:1.0
    • macos/windows
      【ADB_SERVER_ADDR can be "docker.for.mac.localhost" "host.docker.internal" "192.168.."】
      docker run -it --name django_scrcpy -v some_dir:/usr/src/app/media -p 8000:8000 -e ADB_SERVER_ADDR=docker.for.mac.localhost -e ADB_SERVER_PORT=5037 -e DJANGO_SCRCPY_PORT=8000 lim1942/django_scrcpy:1.0
  • start
    docker start django_scrcpy

  • stop
    docker stop django_scrcpy

三.webcodecs

由于浏览器安全限制,VideoDecorder, AudioDecorder需要在https或者本地localhost访问才能使用。
webcodecs是浏览器的硬解码,解码速度和质量比broardway要好,但是兼容性不如broardway,很多浏览器不支持。

1.chrome关闭特定网址安全限制

浏览器输入 chrome://flags image 在Insecure origins treated as secure中加入需要关闭安全限制站点,逗号分隔,配置好点击Relauch.重启后该站点可用webcodecs播放器了。

四.recording
