We have a unreasonable large amount of bug reports that are

why something as trivial as increasing image size for actual
use cases is not reported.

I just tested 16k and it works for some cases, reports "codec
isn't specified for 16k" for others and fails with x264.
What exactly was the issue that could be fixed in FFmpeg?
