[Libav-user] How to use the ffmepg multithread in h264 decode?

[魏伦]

 Recently , I am doing streaming media using ffmpeg . But when the video
size get to 640x480,
the decode speed become too slow to play normal . I see the h264 decoder in
the ffmepg can
do multithread decoding . I am wonder it will work on the single CPU core
machine or not ? And if
works ,what is the thread_count recommended and if there is some doc or
example can help me .
Thanks.
