GPU Hardware encoding with Nvidia?

[ira]

Hey I've just tried out h264 encoding with NVENC (https://developer.nvidia.com/nvidia-video-codec-sdk) and I'm getting some decent results e.g. 1/5th of the time to encode 1080p for the same quality. Has anyone else tried this out?

And is there an linux/opensource encoder out there that does Nvidia encoding?

Thanks for the link, very interesting. Afaict this isn't supported in ffmpeg or any of our other transcoders yet. Some details if you would:

• Are you encoding on the commandline with nvEncoder? if so it could be wrapped as a UMS player obviously.
• Googling nvenc gives a few hints that it's been recently opened to older GeForce, etc chips. If so then it may be worthwhile setting up. Any specific experience with this? EDIT: according to the nvEncodeApp readme:

  NVENC is officially supported on GPU hardware based on Quadro, Tesla, GeForce GRID, or VGX. NVENC on GeForce is not officially supported.

I think this would be nice to implement just for Server Machines and if you have one of those cards... sad that GeForce isn't supported as thats a vast majority of GFX cards out there...

buuuuut you get what you pay for i guess

Actually it will work on a GPU that is Keple based or above and supports CUDA 3.0 or higher. https://developer.nvidia.com/cuda-gpus

Just got it to work with a GTX 650 and a GTX 780M. Pretty damn quick encoding. From Adobe: "This means the hardware can encode up to 240 frames per second of 1920x1080 progressive video."
