Description

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).

  • Priority changed from normal to minor
  • Version changed from unspecified to git-master

Am I correct that the last line containing the final number of frames gets never clobbered?

comment:2 Changed 5 years ago by rogerdpack

I think you're correct ("at the very end" it seems to spit out one good line).

While it's recording though...all you see is this, never any timestamps or frame counts:

FWIW :)
