1Supported by the libva-intel-driver-g45-h264AUR 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 is 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 based players - VA-API is used automatically, if supported format found.
