Needs "-vf crop=412:236:2:0" for bit-identical output.
Not sure if we want to support this, in any case, no
warning is shown, so there is a bug.

This is a deblocking regression, I opened ticket #6882.

Same as for the Technicolor sample: This looks insane and
is therefore unsupported until a real-world encoder
produces such files / patch welcome if no speed-regression
