What is it
VDPAU (Video Decode and Presentation API for Unix) provides a large subset of PureVideo HD functionality for NVIDIA Linux, Solaris, and FreeBSD users. It in essence provides what PureVideo/DirectX Video Acceleration is on the Windows platform. In addition to updated NVIDIA binary drivers that support the API, extensive documentation is available.
Some highlights of VDPAU:
- Defines an API for GPU-accelerated decode of MPEG-1, MPEG-2, H.264, and VC-1 bitstreams.
- Defines an API for post-processing of decoded video, including temporal and spatial deinterlacing, inverse telecine, and noise reduction.
- Defines an API for timestamp-based presentation of final video frames.
- Defines an API for compositing sub-picture, on-screen display, and other UI elements.
Note that VDPAU does not address content protection issues.
Some highlights/limitations of NVIDIA's current implementation:
- Supported on NVIDIA GPUs with the NVIDIA second generation video processors (see list further below)
- Currently, only one video stream can be decoded at a time; NVIDIA hopes to lift this restriction eventually.
VDPAU is currently supported on the following NVIDIA GPUs (as at version 180.16 released December 12, 2008. Stable version 190.29 released February 9, 2009 increased the number of supported GPU's, and version 180.35. quickly replaced by pre-release version 180.37 (March 6, 2009) extends VC-1 decoding to basically all supported VDPAU capable GPU's.
|Desktop GPUs||Mobile GPUs||Motherboard GPUs||Professional GPUs|
Prior to nVidia drivers 180.35, VC-1 support in NVIDIA's VDPAU implementation required GeForce 9300 GS, GeForce 9200M GS, GeForce 9300M GS, or GeForce 9300M GS or 8200/8300/9400/9300 IGP. VC-1 is an alternative to H.264, and is a supported video codec for HD DVDs and Blu-ray Discs. From drivers 180.35, all vdpau-supported cards can do VC-1 decoding.
Support for the following GPUs was added with the stable driver version 180.22:
- Quadro FX 2700M
- GeForce 9400M G
- GeForce 9400M
- GeForce 9800 GT
- GeForce 8200M G
- GeForce Go 7700
- GeForce 9800M GTX
- GeForce 9800M GT
- GeForce 9800M GS
- GeForce 9500 GT
- GeForce 9700M GT
- GeForce 9650M GT
- GeForce 9500 GT
Please note nVidia has acknowledged a bug in their driver that affects a small number of users with G86 and G86M cores. This causes an error 25 when 'opening'VDAPU. From the nVidia Linux forum ( http://www.nvnews.net/vbulletin/forumdisplay.php?f=14&order=desc ) failure to run VDPAU has been reported for:
- GeForce 9400GT ( G86 )
- GeForce 8400M G ( G86M )
Support started with version 180.06. Version 180.41 (20 March 2009) are available in 32bit and 64bit versions. Bugs are fixed with every new release. 180.37 adds fixed VC-1 decoding, improved handling of corrupted/invalid H.264 streams and improvied error recovery. Version 180.41 is considered to be a "pre-release".
Version 185.13 has also been released (13 March 2009) - but there are no reports about this yet. The version 185 line is apparently the new beta line.
Trunk first supported VDPAU in November 2008.
- Deinterlacing (select "Advanced (2x, Hw)" for best results, if video card can handle it)
- Color controls
- Live TV with EPG (due to VDPAU not yet being able to decode more than one stream at once)
Issac Richards suggests making sure composite extension is disabled:

MythTV 0.21-fixes and Ubuntu repository
Jean-Yves Avenard has posted a patch for MythTV 0.21-fixes that backports VDPAU from the development branch. He also provides a Ubuntu/Mythbuntu repository, including mplayer and the Nvidia drivers, for those running that distribution. Add to /etc/apt/sources.list:
deb http://www.avenard.org/files/ubuntu-repos intrepid release
you need to install the GPG signing key with: wget http://www.avenard.org/files/ubuntu-repos/ubuntu-repos.key && sudo apt-key add ubuntu-repos.key && rm ubuntu-repos.key
In addition to "aptitude safe-upgrade", the package nvidia-glx-180 needs to be installed to replace the earlier version of nvidia-glx-*.
Setup a display profile with:
decoder = nvidia vdpau acceleration video + osd renderers: vdpau
and a second recommended as a fallback:
decoder = ffmpeg (Standard) video + osd renderers: vdpau
Compiling MythTV with VDPAU
For Myth to support VDPAU it must be built in. MythTV's compilation script supports this. To enable it use the configure script and the --enable-vdpau option.
The following is an example of how to compile MythTV with VDPAU:
./configure --prefix=/usr --enable-proc-opt --disable-joystick-menu \ --disable-firewire --disable-hdhomerun --disable-xvmcw --enable-xvmc-opengl \ --enable-vdpau --disable-directfb --enable-opengl-vsync
./configure --prefix=/usr --enable-opengl --enable-mytharchive \ --disable-mythbrowser --disable-mythcontrols --disable-mythflix \ --enable-mythgallery --disable-mythgame --enable-mythmusic --disable-mythnews \ --disable-mythphone --enable-mythvideo --disable-mythweather \ --disable-mythzoneminder --disable-mythmovies
- No AGP cards support this feature (But PCI versions exist)
- Warning: Do not install the vdpau beta driver unless you intend to use an NVidia-based video cards exclusively thereafter. Merely installing the nvidia driver breaks digital playback on Intel (and probably any other) video/graphics cards. The nvidia installer *replaces* standard header files (/usr/include/glext.h, glext.h,glxext.h and glx.h) and library files (/usr/lib/libGLcore.so, libGL,so, libGLU.so and libGL.la), with nvidia specific versions which breaks OpenGL playback on other graphic cards. (The 180 series drivers do appear to be usable with non-vdpau capable nvidia GPUs (6200 etc.))
- If you wish to try an nvidia video board instead of your other video/graphic chipset, be careful. Make a mythconverg database backup, and note the SVN of your present working version. In addition, it would be wise to extract the NVidia pkg.run file (NVIDIA-LINUX....pkg.run -x) and make backups of the original files for which copies exist in the ../include/GL, ../lib and ../X11R6 folders. The package help states that the option '--no-opengl-headers' will skip installing the Nvidia OpenGL headers, however it appears that the other libraries will be replaced anyway. It also does not appear to be the case that the '--uninstall' option actually reverses the install, as the orginal files do not appear to be retained. This is a real time-killer ( and WAF killer) and may require a complete re-installation of the system if you wish to revert to a different family of GPU chip.
- Video profiles can not filter based on video format (only by resolution). So if you wanted to use VDPAU for H.264/HD-PVR and Xv for Mpeg2 this is not currently possible.
- Off loading to the GPU may increase its heat out-put. It may seem obvious, but check your GPU temperature and cooling arrangements.
The following configuration changes should be used to prevent issues with VDPAU when used with MythTV:
To prevent vertical and horizontal tearing of the image when viewing live tv or recordings, run the following to disable X Composite Extension (may also cure the all white/gray OSD):
sudo nvidia-xconfig --no-composite
- Enable OpenGL VSync within MythTV.
Note: Reports on 1080i content are of greatest interest for deinterlacers. Do not list a deinterlacer if testing on progressive content like 720p. If reports for 720p and 1080i differ (as they will if using a deinterlacer) consider making two entries or indicating the difference in your success/fail results.
