mpv
mpv • Famous as a video player. • Backend is
ffmpeg. • There is a libmpv that can be used as a library.
libmpv • embedded into other programs as video/audio playback backend.
• Compared to other libraries, it is very simple to use.
libmpv 1. Embed Native Window (Windows / X11) 2. Rendering
API (OpenGL)
Basic Usage mpv_handle *ctx = mpv_create(); mpv_initialize(ctx); const char *cmd[]
= {"loadfile", filename, NULL}; mpv_command(ctx, cmd);
OpenGL
Native Window Renderer (Windows) _mpvHandle = _mpvCreate.Invoke(); _mpvInitialize.Invoke(_mpvHandle); _mpvSetOption(_mpvHandle, GetUtf8Bytes("wid"),
mpvFormatInt64, ref windowId); DoMpvCommand("loadfile", filename);
Tips • If you use libmpv, you can't handle the
raw buffer. • mpv iOS build is pretty hard to do.
Tips You can use libvlc to get a buffer on
callback.
