Hi all.
I am running nimble & nimble transcoder on Ubuntu 2204. I have "Nvidia RTX™ 4000 SFF Ada Generation" on the system with drivers 550.144.03.
In the transcoding scenario, if I set the encoder to libx264 the scenario works and I get the output as I wish. However this obviously isn't using my GPU, only CPU.
If I set the encoder to ffmpeg and use h264_nvenc codec or if I use the encoder nvenc with h264 codec the scenario doesn't work, there's no output.
Does anybody have any idea how to get this working?
