 I don't know. They don't document what the decoder is capable, or not
 capable of. What I do know is that when you use `nvdec`, your first sample
 plays without artefacts, and when you use `cuvid`, there are artefacts.
 The difference between `nvdec` and `cuvid` is the use of the native ffmpeg
 decoder for `nvdec` and the nvidia decoder library for `cuvid`. Another
 known limitation is that `cuvid` won't correctly decode 10bit hdr hevc.
