Phoronix: Using NVIDIA's NVENC On Linux With FFmpeg

With the new NVIDIA 346 Linux driver series NVENC support was made available for accelerated video encoding support under Linux...

Too bad that NVENC, at least on a GTX 680, seems to produce extremely low quality encodes?
(Based on this article in French: http://www.hardware.fr/focus/67/enco...quicksync.html and more specifically this comparison: http://www.hardware.fr/marc/h264nven...?inception720a (you can click on the buttons at the bottom to compare NVENC with x264 veryfast for example))

So with NVidia, it's two different APIs for encode and decode? NVENC and VDPAU? Why not just adopt VAAPI? I think AMD is doing that.

Because NVENC is designed to use dedicated encoding hardware in the GPU, unlike the previous encoder which utilizes CUDA.

I will still use x264

AFAIK AMD uses OpenMAX for encode/decode and VDPAU for decode only, and VAAPI is Intel only, or did I miss some news about AMD?

He's probably refering to this article and the earlier one linked to it.

In my case works however needs nvEncodeAPI.h from NVENC Windows SDK and cuda SDK installed too

Yes. More cooperation with Intel could be key to counter Nvidia's dominance. Using the same API for both decode and encode only makes sense, and VAAPI is already very established.

VA API or OpenMAX aren't designed to use dedicated encoding hardware in the GPUs?
