For video inspection it could be helpful to have a waveform filter for
video. I can replicate this by using yuvdiag
(http://www.silicontrip.net/~mark/lavtools/yuvdiag.c) with mjpegtools and
running:
{{{
ffmpeg -f lavfi -i mandelbrot -pix_fmt yuv420p -f yuv4mpegpipe - |
./yuvdiag -l | ffplay -i -
}}}
I'd recommend allowing options to select Y, U, and/or V individually to
show either overlaid or in parade mode.
I uploaded an output of the above command here:
