1 - Sound is only handled in mono. The fixed psycho acoustic model is
2 very bad, although the quality is surpringly good for such a model !
4 - the bit rate control is really not correct.
6 - Only frame size multiple of 16 are handled.
8 - If you want a specific format to be added (I am thinking about
9 MJPEG, H261) please tell me. Of course, the format you choose should
10 be based on MPEG to be easily integrated
12 - ffmpeg can be used to generate streaming audio/video on a
13 server. Please tell me if you are interested.
