libmediaplayer

This library is designed to simplify ffmpeg for use in media player applications written in pure C. It is thread safe, very fast, and has a pluggable architecture for output renderers for both audio and video streams.

This library does NOT remote control mplayer, or other engines, it is stand alone with libavcodec and libavformat making it very easy to tightly implement a media player into your application.

Usage is very simple:

mp_t *mp;
mp = mp_new();
mp_load(mp, "filename.avi");
if (mp_num_streams(mp, CODEC_TYPE_AUDIO) > 0) mp_setup_stream(mp, 0, PLAYER_AUDIO_ALSA, NULL);
if (mp_num_streams(mp, CODEC_TYPE_VIDEO) > 0) mp_setup_stream(mp, 0, PLAYER_VIDEO_XV , NULL);
mp_open(mp);
mp_play(mp);
mp_wait(mp);
mp_close(mp);
mp_free(mp);Currently four renderers are supported, ALSA, XV, DirectFB and OpenGL via GTK+, though it is not hard to implement your own renderer.

Renderers are very simple to implement, for audio all you have to do is define the functions: new, free, open, close, getdelay, write, pause, resume and call the macro: DEFINE_AUDIO_RENDERER(PLAYER_AUDIO_FOOBAR, new, free, open, close, getdelay, write, pause, resume)

It is very similar for Video.
