Summary of the bug: basically, in the presence of multiple log messages,
the default "size out" gets lost:
How to reproduce:
Run a dshow capture session with a system under heavy load (or any system
that can't keep up with the requested encoding in realtime):

Notice that "frame= 163 fps= 24 q=29.0 size= 148kB time=00:00:05.43
bitrate= 222.6kbits" type messages are basically lost/obscured/being
covered over by the warning messages being shown.
This can also lead to some odd concatenated lines being shown on the
console, like this for instance (the "31 drop=0" are from the preceding).
