Hello, I am trying to transcode a 10 bit hevc video stream to 8 bit hevc or h264. Here is the relevant data from ffprobe:
Stream #0:0: Video: hevc (Main 10), yuv420p10le(tv, bt2020nc/bt2020/smpte2084) I have tried many different combinations, usually something like this: ffmpeg -hwaccel cuvid -i input.mkv -c:v h264_nvenc -pix_fmt yuv420p output.mkv I have also tried using hevc_nvenc encoder, and tried using -vf "format=yuv420p", although I do not fully understand what -vf is doing. I usually get error messages like this: Impossible to convert between the formats supported by the filter 'Parsed_null_0' and the filter 'auto_scaler_0' Error reinitializing filters! Failed to inject frame into filter network: Function not implemented Error while processing the decoded data for stream #0:0 Conversion failed! I have found some questions on this forum saying that nvenc doesn't support anything other than yuv420p, although ffmpeg -h encoder=h264_nvenc says that it supports p010le. If this is the case, is there a way to make the pixel conversion in software and everything else in hardware? Thanks for the help! _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
