The video has already been captured, so there's no helping my data if
ffenc_ljpeg isn't lossless (which would be a bit surprising, but
possible). But in any case, I have really wanted a tool to verify that
two videos are in fact pixel-identical and perhaps to show visual
diffs. Does anyone know of such a tool?
