General Support / Questions Hardware Encoding

Try the following:

ffmpeg-video=-c:v hevc_nvenc -preset hq -vf yadif=0:-1:1 -rc constqp -rc-lookahead 60 -spatial_aq 1 -temporal_aq 1 -nonref_p 1 -cq 26 -map 0:v -sn

It was the map parameter missing that it didn’t like, not having for video when the audio was being mapped caused only the audio in the output.

Here is what I tested with:

[HEVC MKV ffmpeg NVidia]
