Comment (by jbvsmo):
Sorry, the command line is the simplest possible. It is just a
filterchain.
I tried with some files and all gave the same result. I will upload the
original
The error also shows on ffplay, so I assume libx264 is not the problem
----
Another error:
When scaled down, the "edgedetect" filter will make the original output
black and white. If removed the "scale" filter, everything works fine.
{{{
$ ffmpeg -i Madeon_Pop_Culture.flv -filter:v 'scale=320:trunc(ow/a/2)*2,
split[a][b]; [a]pad=iw*2[aa]; [b]edgedetect=[bb]; [aa][bb]overlay=w' -t 10
-c:a copy -b:v 800k side_by_side_edge.mp4
}}}
Another example attatched.
