ffmpeg.exe -i Untitled.bmp -vf scale=out_color_matrix=bt709:flags=lanczos
-pix_fmt yuv422p 42224k.y4m
the 42224k.y4m works fine in video players and is 3840x2160 just like the
bmp. file should be 16.588.800 bytes but is 16.588.858.
ffmpeg.exe -f rawvideo -pixel_format yuv422p -video_size 3840x2160 -i
42224k.y4m -c:v libx265 -x265-params crf=18 422.mkv
this is producing trash it is producing odd data at the left the right
part and moves the chroma relative to the rest of the image. x264 was also
tried same output.
