Nvidia CUVID Accelleration

Post by vanel86 » Wed Jul 06, 2016 7:34 am

Since a few weeks ffmpeg can decode video using native acceleration(CUVID) on Nvidia GPU(i think that you need to match nvenc requirements to have it work driver/gpu wise) just by adding --enable-cuvid, could you kindly add it to the automated builds?

Thank you!

appears it require the nvidia libraries:

which means that putting it in a normal distro wouldn't work since then it would fail on everybody's boxes who don't happen to have nvidia cards handy...I should look into adding nvidia support to my scripts sometime ...

Any plans yet to support the latest CUVID Roger? I see FFmpeg 3.2 supports it properly now.

CUVID and OpenCL would benefit from /DELAYLOAD...

I've been using it to decode h.264, for a few weeks now and it been working really well. What would DELAYLOAD do to make it better?

It would allow FFmpeg to be built and used on machines where the necessary libraries are not present. Only when trying to use the CUVID features for example would the dependency DLL be attempted to be loaded into memory.

That would be great.
