VDPAU For NVIDIA's Maxwell GPU On Linux
With this morning's release of the NVIDIA 334.21 Linux graphics driver there is now support for GPUs with VDPAU Feature Set E.
VDPAU Feature Set E is the latest revision of NVIDIA's PureVideo hardware that's found in the brand new Maxwell graphics processors. With the GeForce GTX 750 series support for VDPAU Feature Set E, there is support for H.264 decoding up to 4096 x 4096 and MPEG-1/MPEG-2 streams up to 4080 x 4080. These new GPUs also support enhanced error concealment when dealing with the decoding of corrupted video streams.
There's also been talk of Maxwell GM107 GPUs partially supporting hardware-based H.265 / HEVC video decoding, but with today's 334.21 driver release there's no indications yet of this being supported by the NVIDIA Linux driver with this newest driver release where it makes official the GTX 750 series support.
For those curious what the vdpauinfo output is for a GeForce GTX 750 on Ubuntu Linux embedded below is the output from the new graphics card on the 334.21 Linux GPU driver.
