[FFmpeg-user] Can I do scaling better?

I've had concerns with that, too, but I can't think of another way to
guarantee square pixels AND scale downs for arbitrary inputs.

It is part of a larger script, unfortunately.

I just wanted to make sure there wasn't some magic to the scale filter that
I'd yet to stumble upon in the documentation. I'm thinking of adding some
sort of pre-analysis to my script so that the ffmpeg line is as simple as
possible.

My other option is that I finally learn a real programming language and
rebuild my entire app ;)

Thanks!
