This is the second command:
ffmpeg -y -f rawvideo -vcodec rawvideo -pix_fmt rgb24 -s 1280x720 -r
59.94 -i - -f mp4 -q:v 5 -vcodec rawvideo -pix_fmt rgb24  -an
output.avi

This command forces mp4 for a file called "avi" which is unusual and
uses the rawvideo codec which is not supported in mp4: Are you sure
that this command produces a readable output file?

(The bug in FFmpeg - that it produced invalid output files for above
command line - was fixed some time ago.)

Yes I am, and ffmpeg is altering the video levels in the process.
How to submit a feature request or stop ffmpeg from forcing video levels to 0 - 255 or 16 - 235?
