| 33 | The <application>libvdpau</application> package contains a library which
|
---|
| 34 | implements VDPAU.

| 37 | <para>
|
---|
| 38 | VDPAU (Video Decode and Presentation API for Unix) is an open source
|
---|
| 39 | library (libvdpau) and API originally designed by Nvidia for its
|
---|
| 40 | GeForce 8 series and later GPU hardware targeted at the X Window System
|
---|
| 41 | This VDPAU API allows video programs to offload portions of the video
|
---|
| 42 | decoding process and video post-processing to the GPU video-hardware.
|
---|
| 43 | </para>
|
---|
| 44 |
|
---|
| 45 | <para>
|
---|
| 46 | Currently, the portions capable of being offloaded by VDPAU onto the GPU
|
---|
| 47 | are motion compensation (mo comp), inverse discrete cosine transform
|
---|
| 48 | (iDCT), VLD (variable-length decoding) and deblocking for MPEG-1, MPEG-2,
|
---|
| 49 | MPEG-4 ASP (MPEG-4 Part 2), H.264/MPEG-4 AVC and VC-1, WMV3/WMV9 encoded
|
---|
| 50 | videos. Which specific codecs of these that can be offloaded to the
|
---|
| 51 | GPU depends on the version of the GPU hardware; specifically,
|
---|
| 52 | to also decode MPEG-4 ASP (MPEG-4 Part 2), Xvid/OpenDivX (DivX 4), and
|
---|
| 53 | DivX 5 formats, a GeForce 200M (2xxM) Series (the eleventh generation of
|
---|
| 54 | Nvidia's GeForce graphics processing units) or newer GPU hardware is
|
---|
| 55 | required.
