------- Comment #3 from Edward Hervey  2009-02-25 07:41 UTC -------
A few recommendations of how to pursue this:

* Create a sys/vdpau/ path in gst-plugins-bad
* Write vdpau configure.ac/Makefile.am code to build a blank plugin against it.
(Proof of concept of detection/linking of the vdpau library).
* Write 2 simple plugins to convert RAW Video GstBuffer <=>
VdpVideoSurface/VdpBitmapSurface. (Proof of concept of RAM <=> GPU
communication). You might have to create a gstreamer 'mime' type for these
buffers (video/x-vdpau-video-surface, video/x-vdpau-bitmap-surface, .??).
* Write a sink using the VdpDevice that takes VdpVideoSurface or
VdpBitmapSurface. (Proof of concept of synchronous VDPAU display).
* Wrap the VdpVideoMixer feature (de-interlacing, colorspace conversion, noise
reduction, sharpness reduction, ...). (Proof of concept of using simple VDPAU
processing features).
* FINALLY : Wrap the VdpDecoder. At this point, if you've done all the steps
above, you will have narrowed down your source of issues to a small range (You
already know vdpau works, you can send/receive data from it, you can display
it, and you can do some processing on it). You will most likely have to do some
format-specific parsing of the encoded data buffers before passing them on to
the VDPAU code (according to my reading of the specs).
