 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.
