Have you tried a mailinator email address?

It does appear that they support alpha, but it would still be a pain to implement without writing to a gl texture. They may not support that for security (drm) reasons.

Ive only scanned trough it fast but according to this: http://http.download.nvidia.com/XFree86/...index.html

It looks like it should be possible to decode the frame and blend it with the underlying GUI, and then refeed that VdpOutputSurface to render the rest of the gui ontop of it. and this could be done by rendering to texture twice, which should include pixelshaders I think?, not that we use pixelshaders in the gui now but we should in the future to support blur and such.

The VdpOutputrendering supports alpha blending in a GL type of way so if we can just handle which should be feed first then it would be possible.
Though splitting the GUI in two and the big trouble is when there isnt a clear line, as with jmarshalls example when you blend stuff skinwise ontop of the video, as the scanlines in PM3 home.

Also from what I can deschiffer in the api it looks like one could do lots of surfaces and post process them in vdpau first and skip OpenGLs rendering, and let vdpau do that. This could be a way aswell. Only doing this on video ofc, and it relies on that the gl renderer is abstracted enough for us to switch between them easily after creating the context, IMO its probably the worse way of doing it though, duplicated code and such.

Anyways it might be possible and that is interesting.
