A NVIDIA VDPAU Back-End For Intel's VA-API

[RealNC]

128MB is more than plenty for all kinds of video. I guess there's some other problem and this is just a misleading error message.

Well, I am just hoping Nvidia will make some changes to their driver so cards with only 128MB VRam + turbocache can play HD video.
My Quadro FX 570M (128MB) can play non-HD videos without a problem, but it always gives error 23 (insufficient vram) when I try to play video with 720p or higher resolutions. nvidia-settings does show that this card has 512MB vram(128MB onboard vram + 384MB turbocache, i guess), but it seems the driver doesn't make use of the turbocache.

Phoronix: A NVIDIA VDPAU Back-End For Intel's VA-API

Just over a month ago we shared that patches had emerged to support Intel's VA-API in MPlayer and FFmpeg. VA-API supports popular video formats such as MPEG-4 and VC-1 and is able to accelerate IDCT, Motion Compensation, LVC, bit-stream processing, and other functions, but this video API has not picked up much speed yet. The only display driver to have implemented support for VA-API in the hardware is Intel's closed-source driver (the one that's a bloody mess) for the Poulsbo chipset, which is found in a few select netbooks/nettops. However, it is now possible to use Intel's VA-API with NVIDIA hardware (the GeForce 8 series and later) and soon will be possible to use this video API on ATI/AMD hardware too.
