24. mpv

25. mpv • Famous as a video player. • Backend is

    ffmpeg. • There is a libmpv that can be used as a library.

26. libmpv • embedded into other programs as video/audio playback backend.

    • Compared to other libraries, it is very simple to use.

27. libmpv 1. Embed Native Window (Windows / X11) 2. Rendering

    API (OpenGL)

28. Basic Usage mpv_handle *ctx = mpv_create(); mpv_initialize(ctx); const char *cmd[]

    = {"loadfile", filename, NULL}; mpv_command(ctx, cmd);

29. OpenGL

30. Native Window Renderer (Windows) _mpvHandle = _mpvCreate.Invoke(); _mpvInitialize.Invoke(_mpvHandle); _mpvSetOption(_mpvHandle, GetUtf8Bytes("wid"),

    mpvFormatInt64, ref windowId); DoMpvCommand("loadfile", filename);

31. Tips • If you use libmpv, you can't handle the

    raw buffer. • mpv iOS build is pretty hard to do.

32. Tips You can use libvlc to get a buffer on

    callback.
