I would like to add it to libavformat for ffmpeg. So what exactly is the demuxer? I think it just extracts the video frames for the decoder, but I'm not sure..





If I add my demuxer + codec to libavformat/libavcodec, will the ffmpeg project be also get the files I added? I want the ffmpeg project  have the .smv format (as well as mplayer). Thanks again!
