===XvMC===

MPEG-2 and MPEG-4 offloading (NVIDIA's closed driver only supports MPEG-2, prefering VDPAU) via motion compensation and iDCT offload. Extends the Xv extension, using XvPorts. The [http://www.xfree86.org/~mvojkovi/XvMC_API.txt 1.0 API specification] was introduced in 2000.

===VAAPI===

The Video Acceleration API, a vendor-independent replacement for XvMC.

The Video Acceleration API, a vendor-independent replacement for XvMC. It has backends for both VDPAU and XvBA.

==VDPAU==

NVIDIA's proprietary [[Xorg hell|X.org]] video acceleration API, comparable to Microsoft's [http://en.wikipedia.org/wiki/DirectX_Video_Acceleration DXVA]. It is independent from [[CUDA]].

NVIDIA's proprietary [[Xorg hell|X.org]] video acceleration API, comparable to Microsoft's [http://en.wikipedia.org/wiki/DirectX_Video_Acceleration DXVA]. It is independent from [[CUDA]]. Builds atop NVIDIA's [http://en.wikipedia.org/wiki/Nvidia_PureVideo PureVideo]. On [[Debian]], I have to manually link libvdpau. From <tt>/usr/lib</tt>:

<pre>sudo ln -s vdpau/libvdpau_nvidia.so.260.19.29 libvdpau_nvidia.so

sudo ln -s vdpau/libvdpau_trace.so.260.19.29 libvdpau_trace.so</pre>

==XvBA==

ATI's answer to VDPAU, built atop ATI's [http://en.wikipedia.org/wiki/UVD2 Unified Video Decoder].
