Comment (by burek):
As discussed on #ffmpeg-devel irc channel, I would suggest that at least a
hint message is produced when the pixel format is unspecified at command
line and it is not yuv420p in the source file.
A hint/warning message can be any kind of a custom message that notifies
the user that his video might not be playable on some media players, due
to this issue.
Since I'm required to suggest a hint message and am not quite familiar
with correct terms, I'll just suggest a simple message like:
''"Warning: You didn't specify '-pix_fmt yuv420p' option, so the same
pixel format from your input will be used. Your video might have issues
when played back on some media players since they mostly use 'yuv420p'
pixel format with h264 videos."''
