Thanks a lot. By the way, how can I get all available encode options for mjpeg? and how can I set these options? I have read some docs like http://ffmpeg.org/doxygen/trunk/group__avoptions.html, and some ffmpeg source code, but I'm still confused with it. Is there any examples for setting encode options? The example under ffmpeg/doc/examples directory only show a simple option of H264
