When using the libx264 encoder on 8bit raw input, the resulting video shows up slightly darker than the original. Using this command:
ffmpeg.exe -y -hide_banner -vcodec rawvideo -f rawvideo -r 60 -s 658x492 -i \\.\pipe\DEV_000F315B978C<file://./pipe/DEV_000F315B978C> -pix_fmt gray -c:v libx264 -crf 23 X:\Videos\One_2020T115817.avi When running the compression using nvidias encoder, h264_nvenc, the darkening of the video does not occur. Using this command: ffmpeg.exe -y -hide_banner -vcodec rawvideo -f rawvideo -hwaccel nvdec -r 60 -s 658x492 -i \\.\pipe\DEV_000F315B978C -pix_fmt gray -c:v h264_nvenc -crf 23 X:\Videos\One_2020T120806.avi Is this known behavior? Any reason for the difference in the resulting video?
