[FFmpeg-devel] [PATCH] ffmpeg: raise level for message printed in case of auto-select pixel format

[Werner Robitza]

Taking a step back, remember that this is just about warning users that
what they're doing might not work. Simple as that.
There is no inherent issue in ffmpeg, and the defaults that are chosen are
absolutely fine with me if the goal is to preserve quality as much as
possible.

But, from my experience, users do not always know what H.264 level or
profile they want (or know what these are, even).
They have no clue about chroma subsampling either. They just encode video
as part of their toolchain, without being experts on the subject.

Just to give you an example, here's a list of questions I encountered,
where users had problems with the default conversion to 4:4:4:

I'm sure there are lots of other examples on the mailing lists, forums and
Q&A sites all over the Internet.
Raising the level of the message would just provide for better end user
experience.
