We are aware of cases of visual corruption and in some<br>cases GPU hangs. We will be working on these issues over the next<br>several NVIDIA driver releases.<br><br>While NVIDIA's VDPAU implementation is not ready for end user use yet,<br>it should be far enough along that interested application developers<br>can begin working with it.<br><br>Additionally, NVIDIA has developed patches to ffmpeg and MPlayer to<br>demonstrate a video player using VDPAU:<br><br> <a href="ftp://download.nvidia.com/XFree86/vdpau/mplayer-vdpau-3076399.tar.bz2">ftp://download.nvidia.com/XFree86/vdpau/mplayer-vdpau-3076399.tar.bz2</a><br><br>These patches include changes against libavcodec, libavutil, ffmpeg,<br>and MPlayer itself; they may serve as an example of how to use VDPAU.<br><br>Once we do some further testing, bugfixing, and cleanup, we will<br>contribute the MPlayer patches to the MPlayer developers.<br><br><br>If other hardware vendors are interested, they are welcome to also<br>provide implementations of VDPAU.
