How to enable hardware acceleration of video decoding in mplayer with Intel HD3000 on Vivid?

  • 772

There used to be a vaapi build of mplayer but it doesn't seem to be maintained any more and doesn't work in Vivid.

Default mplayer2 build from the repo uses 40% of CPU during 720p playback. Same as totem. VLC does have some hardware acceleration support and uses 13% but I liked mplayer's UI more and it used less than 5% with.

Is it currently possible to use mplayer with hardware acceleration on Intel integrated graphics?

    OK, I found mpv (a fork of mplayer) which does everything I wanted and carried all the good UI qualities from mplayer2.

    To enable vaapi support, run it with mpv --vo=opengl-hq --hwdec=vaapi file.mkv

    or add

    vo=opengl-hq
hwdec=vaapi

    to ~/.config/mpv/mpv.conf.

    Previously the answer suggested using vo=vaapi and hwdec=vaapi but this is not a recommended setup anymore. See comments.

  2. SNA is the best acceleration method. You should check your config file if you have one. Another way is to renice the process. For example: 

    ps ax|grep mplayer

    find the given process and renice it

    renice -20 43332

    You can do it as root only (maybe it is possible with sudo: sudo renice -20 43332 ).
