VDPAU is just a userland API for offloading video decoding to the hardware. It doesn't describe how to actually communicate with the hardware. i.e. if you are using the Nvidia proprietary driver, it is an api for tools like mplayer etc, to hand video frames to that driver. Other standard and proprietary methods also exist, Intel's VAAPI, XvMC, etc... Unfortunately, none of this helps with driver development. robert. > Graphics and gfx cards isn't an area wherer I have much expertise > anyway. >=20 > References: > 1) http://en.wikipedia.org/wiki/VDPAU > 2) http://en.wikipedia.org/wiki/CUDA --=-FWA+14+f8Ad5xqAhnE+7 Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEABECAAYFAklf4qgACgkQM4TrQ4qfROOhaQCghZRHznZrZ5ys8mOZPdpcfiLZ +hkAniV2DhDJfp9Epd//y1fj6gzCvfyo =Rid/ -----END PGP SIGNATURE----- --=-FWA+14+f8Ad5xqAhnE+7--
