I had the same issue, and could not resolve it. However, I had a different issue with ffmpeg on another project, reinstalling ffmpeg with the following command resolved both issues.

conda install -c conda-forge ffmpeg

Hope this will help 😃

you need to compile ffmpeg with appropriate header along side with other needed headers for example: ./configure --enable-nonfree --enable-gpl --enable-libnpp --enable-libx264 Then you can make and install more information for nvidia cards here https://docs.nvidia.com/video-technologies/video-codec-sdk/ffmpeg-with-nvidia-gpu/ gl
