1Supported by the libva-driver-intel-g45-h264 package. See H.264 decoding on GMA 4500 for instructions and caveats.

In order to check what profiles (features) are supported by your GPU, run the following command, which provided by the libva package:

$ vainfo

VAEntrypointVLD means that your card is capable to decode this format, VAEntrypointEncSlice means that you can encode to this format.

Configuration

libva-vdpau-driver has to be enabled manually with an environment variable globally or locally per user.

export LIBVA_DRIVER_NAME=vdpau

Supported software

GStreamer

Install gst-vaapi package, available in the official repositories.

$ gst-launch-1.0 playbin uri=file:///path/to/foobar.mpeg

VA-API is used automatically, if supported format found.

GStreamer based players:

  • totem: no configuration needed.

MPlayer

Install mplayer-vaapi package, available in the official repositories.

$ mplayer -vo vaapi -va vaapi foobar.mpeg
  • -vo - Select vaapi video output driver
  • -va - Select vaapi video decoder driver
Note: You can also use mplayer2AUR with VDPAU backend. See MPlayer#Enabling_VDPAU for more information.

MPlayer based players:

  • gnome-mplayer: to enable hardware acceleration: Edit -> Preferences -> Player, then set Video Output to "vaapi".
  • smplayer: to enable hardware acceleration: Options -> Preferences -> General -> Video, then set Output driver to "vaapi".

VLC media player

Install vlc package, available in the official repositories.

To enable hardware acceleration: Tools -> Preferences -> Input & Codecs, then check "Use GPU accelerated decoding".
