Video Acceleration API is a specification and open source library to provide hardware accelerated video decode/encode.

## Supported hardware

Open source drivers:

- AMD Radeon 9500 and newer GPUs are supported by the libva-vdpau-driver package (available in the official repositories) together with the ati-dri driver.

- Intel GMA 4500 series and newer GPUs are supported by the libva-intel-driver package, available in the official repositories.

- NVIDIA GeForce 400 series and newer GPUs are supported by the libva-vdpau-driver package (available in the official repositories) together with the nouveau-dri driver. It uses the nouveau-fw package, which contains the required firmware to operate that is presently extracted from the NVIDIA binary driver.

Proprietary drivers:

- AMD Radeon HD 4000 series and newer GPUs are supported by the libva-xvba-driver package, available in the AUR. It uses the catalyst-utils driver for Radeon HD 5000 series and newer, and catalyst-legacy-utils for Radeon HD 4000 series.

- NVIDIA GeForce 8 series and newer GPUs are supported by the libva-vdpau-driver package (available in the official repositories) together with the nvidia-utils driver.

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.

## 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 mplayer2 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".
