 Summary of the bug:

 -v quiet overrides even an explicit -stats flag.

 I'm trying to write a python script that uses ffmpeg for transcoding.  I'd
 like to retain the progress for the user, but scrap the initial info (and
 other info lines).  I'll probably devise some filter in the meanwhile, but
 this still seems broken.

 As it stands now, I can't see what -stats is supposed to do.  It is always
 on, except when -v turns it off, and then it is always off.  This seems
 very odd.

 I suspect the solution will be to make the debugging level of the progress
 output conditional on the -stat flag.  Without actually finding it in the
 code, I think this should be fairly straightforward.

 How to reproduce:
 {{{
 % ffmpeg -v quiet -stats -i input ... output
 % ffmpeg -v panic -stats -i input ... output
 % ffmpeg -v fatal -stats -i input ... output
 % ffmpeg -v error -stats -i input ... output
 % ffmpeg -v warning -stats -i input ... output

 Running on Windows XP in Cygwin Console, but I really doubt that matters.
