Ha, good point. So with mplayer vo=vdpau, CPU load was at something over 12%.

Doing:

$ mpv --vo=vdpau --hwdec=vdpau $file
 (+) Video --vid=1 (*) (h264)
 (+) Audio --aid=1 --alang=eng (*) (aac)
Trying to use hardware decoding.
AO: [alsa] 48000Hz stereo 2ch float
VO: [vdpau] 1280x720 vdpau
AV: 00:00:50 / 00:02:36 (32%) A-V:  0.000

did bring it down to 5-6ish.

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND
12482 boris     20   0 1026628  74272  47632 S   5.6  0.5   0:02.77 mpv

so I'm guessing this should be using hw accel now...

In any case, output looks fine again too.

Thanks.
