The new version is up* and I did a quick benchmark: ffmpeg-git-20151120-64bit-static$ ./ffmpeg -i a.mp4 -c:v libvpx-vp9 -b:v 1M -cpu-used 4 -threads 4 -c:a libvorbis b.webm fps= 13 ffmpeg-git-20151124-64bit-static$ ./ffmpeg -i a.mp4 -c:v libvpx-vp9 -b:v 1M -cpu-used 4 -threads 4 -c:a libvorbis b.webm fps= 17 Not sure if the multi-core command (4 cores, no HT) is correct but I get like only 80% CPU usage on average
try to set it higherwhen i build RPM packages on my 4-core HT machine inside a VM it's faster to use "%_smp_mflags -j10" instead just "%_smp_mflags -j8" or lower
