h264_nvenc should be used.
h264_nvenc is an encoder, and I guess you are confusing things here. This
issue is not about the encoder.
But the issue is about the decoder. And more specifically, about Cuvid
decoders (h264_cuvid, hevc_cuvid and so on).
> ffmpeg -init_hw_device cuda=gpu:0 -hwaccel cuda -hwaccel_output_format
cuda -hwaccel_device gpu -hwaccel cuda -i input.mp4 -c:v h264_nvenc -y
test-out.mp4
Your example does not use Cuvid decoders, which are the subject of this
issue.
