Using this sample: https://btbn.de/files/chromakey_sample.mp4 ffmpeg -f lavfi -i color=c=black:s=1280x720 -i chromakey_sample.mp4 -an -c:v libx264 -preset veryfast -crf 18 -shortest -filter_complex "[1:v]chromakey=0x70de77:0.1:0.2:0:1[ckout];[0:v][ckout]overlay[out]" -map "[out]" -y output.mkv The last parameter to the chromakey filter enables opencl acceleration. Hi, Could you please send the patch as attachments? I merge the code, but some compile errors occur.
