As you can see, ffmpeg is built with vaapi and threading support. I'm
pretty sure mplayer2 uses ffmpeg. I also seem to remember kernels >3.13
are required, as is mesa >9.2 (in the case of the NUC.)
I don't remember why I switched to mplayer2 now, but quite a while back
I was having a problem with mplayer and someone on IRC somewhere said to
try mplayer2. It solved whatever issue I had and I've been using it
since. Wish I could remember what it was though...
As I said, CPU usage as reported by top while playing 1080p with
mplayer2 was 80-90% so it must be doing it on the CPU. I tried playing a
1080i recording with mplayer with 5 channel audio and it takes 5-10%. I
know for sure xbmc and mythtv are using vaapi and it works beautifully.
