	"Hardware Accelerated Video Decoding" is the when a video-playback software-application offload portions of the [http://en.wikipedia.org/wiki/Video_decoding video decoding process] to the [http://en.wikipedia.org/wiki/Graphics_processing_unit GPU (Graphic) hardware], it does this by executing specific code algorithms on the GPU. In theory this process should also reduce bus bandwidth requirements.

	[http://ffmpeg.mplayerhq.hu FFmpeg] should probably be the reference and test platform for all hardware accelerated video decoding development. The reason for this is that XBMC used FFmpeg as the base for its [[~~DVDPlayer~~\|DVDPlayer-playback-core]] (video player) with FFmpeg doing the demuxing and decoding. Also, since both [http://ffmpeg.mplayerhq.hu FFmpeg] and [http://xbmc.org XBMC Media Center] are cross-platform code we could possible also get help from non-XBMC developers as well.

The XvMC [http://en.wikipedia.org/wiki/API API] allows a simple way to add hardware accelerated video decoding to video-playback software-applications. XvMC is thus probably the first step to take towards Hardware Accelerated Video Decoding in XBMC's [[Linux ~~port project~~]], as an existing XvMC library such as [http://www.openchrome.org libxvmc (from the openChrome project)] could be implemented in XBMC's [[~~DVDPlayer~~]] video player core, (and that fork of libxvmc could later serve as a base which can be extended to support additional codecs and additional hardware/decoding methods).
