nvenc / nvdec supported?

nvenc requires ffnvcodec, but it seems this dependency cannot be specified?

Does your excellent generator support nvenc/nvdec?

commented

Okay, I found out that I needed to do the following to enable nvenc:

  • git clone https://github.com/FFmpeg/nv-codec-headers
  • copy the include folder from this cloned repo to the msvc folder
  • add the option --enable-ffnvcodec to the PGOPTIONS environment variable in the batch file.
  • run the batch file to generate the project

Closing this then.

FFVS emulates the behavior specified in the ffmpeg source configure script which currently autodetects nvenc/nvdec so all you need is the headers in the include folder.

Although I have update the bat files so that the explicitly force enable the options anyway.

Nice!

I am not sure you need the CUDA SDK, nvenc and nvdec themselves do not need CUDA I believe, but other parts might need it, not sure. It does compile without the CUDA SDK, and nvenc is listed as encoder after the build completes.

I succeeded in making a build, but it is now stuck in an infinite loop in ffmpeg (we are feeding rendered raw images through a Windows pipe). This used to work with an older FFMPEG that we build using the windows build helpers under Ubuntu. So back to drawing board ;-)
