-------------------------------------+-------------------------------------
I am trying to convert yuv420p pixels to rgb24 and confine the range of
the rgb24 pixels to 16 - 235 using lutrgb.
It works semi successfully but lutrgb leaves behind some errant pixels
which are > 235 or < 16.
Command line:
ffmpeg -y -i "D:\Videos\SonyAX53\C0059.mp4" -pix_fmt rgb24 -c:v
libx264 -vf
"lutrgb=r='clip(val,16,235)':g='clip(val,16,235)':b='clip(val,16,235)'"
-c:a pcm_s16be RGB.mov
=================================================================================================
Console output:
D:\Programs\ffmpeg\Batch_files>ffmpeg -y -i
"D:\Videos\SonyAX53\C0059.mp4" -pix_fmt rgb24 -c:v libx264 -vf
"lutrgb=r='clip(val,16,235)':g='clip(val,16,235)':b='clip(val,16,235)'"
-c:a pcm_s16be RGB.mov
