[FFmpeg-devel] [PATCH] waveform monitor filter

[Mark Himsley]

This is quite an early/raw version of a luminance waveform monitor.
I'd like to add to it with vector-scope, RGB parade, etc.

At this stage I'm just looking for some comments from you experienced
folks whether I'm doing something crazy.

I've been testing this filter with this, to overlay the waveform monitor 
on top of the original video (thanks to Nicholas for the fifo workaround).

ffmpeg -i input.mov -vf
"split[one][two];[two]wfm_luma,scale=256:256[wfm];[one]fifo,[wfm]overlay=0:0"
-aspect 16:9 -vcodec dvvideo -acodec pcm_s16le -ac 2 -y output.mov

Thanks.
