Well, the performance numbers I quoted certainly show that. Perhaps one of your components was compiled without assembly support, or you need to enable threading for libvpx somehow or so... but as is, it's too slow. > Also, h264 encoding produces a very good video output but audio stutters > and is very unclear. There are gaps in the middle... Does it encode at realtime, i.e. speed >= 1.0? > Also, setting -video_size 480x240 seems to have no effect at all. How can I > change output video size? "-scale 480x240" or insert the scale filter: "-vf scale=480:240" (or "-vf scale=480:-2". A smaller output should encode significantly faster. Before you don't achieve fps>=25/speed>=1.0, I believe we don't need to further debug the audio issues. (I'm not ruling out that there are further issues, I'm just trying to tell you what's obvious to me.)
