This is almost everything you need to do... The only other important 
thing is that you must send the frames at the correct time (look at the 
DTS). And remember to always pass a valid PTS to av_write_frame() (if 
you are reading frames from a file by using libavformat, you need the 
AVFMT_FLAG_GENPTS flag).

I think ffmpeg.c's code is cleaner, and easier to understand.
