We ask users to report bugs with "--loglevel 99" so this is irrelevant if
it's a DEBUG.

In my case I get a lot of reports from users about ffmpeg spamming logs
with obscure warnings.
This happens on legal files as per my "SPS/PPS truncation" patch which
scares them into thinking the file is broken.
The same goes with spamming logs when there is some data corruption with
warnings which are very obscure.
