Doom9's Forum - View Single Post - LAV CUVID Decoder - High Quality Hardware decoding for NVIDIA

nevcairiel · 25th March 2011, 23:35

This is a decoder for NVIDIA GPUs, it does not work with ATI/AMD or Intel, and it never will!

Requirements/Recommendations
- NVIDIA PureVideo HD capable graphics card (VDPAU Feature Set A or better - see list here)
- At least 256MB of Video RAM, 512MB recommended
- Recent NVIDIA Drivers - CUDA 4.0 compatible driver recommended (270 series), older drivers may work with the "Old CUDA" build.
- Vista/7 recommended due to much improved driver handling, but XP SP3 "should work" (see hints below)

Performance
- 1080p60 decoding is only supported on VP4 hardware (VDPAU Feature Set C)
- When encountering performance issues, turning off the "HQ DXVA processing" option will yield the best gain in performance, at a minimal loss of quality.
- Using the latest driver (275.33 at the time of writing), can greatly improve the performance.

Hints
- When running on Windows XP, its recommended to turn the "Use HQ DXVA processing" setting off, its not fully supported on XP and might cause image corruption.

Known Issues
- The decoder will try to decode all video streams, and not refuse formats that are not supported.
- VC-1/MPEG4-ASP VFR content will most likely not play properly.

reserved for FAQ, etc.
