These have no effect (and make debugging more difficult).
This has no effect, in combination with --arch=arm,
it looks stupid.
Is this needed?
If yes, I'd be interested why.
Does it have a performance effect?

If you have a performance issue, I'd start with removing these.

This looks very strange / please try to avoid using
Did you test different swscale options?
Please do not top-post here, Carl Eugen
