[FFmpeg-devel] [PATCH] libavfilter/vf_colorrange_cuda: CUDA-accelerated video filter for MPEG and JPEG color range conversions

[Roman Arzumanyan]

Hello,

This patch adds video filter which does color range conversion similar to swscale scaling filter.

How to use it:
./ffmpeg \
  -hwaccel cuda -hwaccel_output_format cuda \
  -i /path/to/intput/file.mp4 \
  -vf colorrange_cuda=range=mpeg \
  -c:v h264_nvenc \
  -y /path/to/output/file.mp4
