Hi!

I've got an error with some transcoding Profiles.
I have severals profiles with predefined Bitrates for Video and Audio.
For Handy 3G or low bandwith Internet... 3000 DSL...
e.g.
1500 kb/s Videobitrate
36 kb/s Audiobitrate
=> Total Bandwith of 1536 kb/s
And some Profile with no Limitation of bandwith (using them on LAN).
(see attachment)

on previous Versions <4.1 everything worked fine.
Bandwith was calculated correct on status page and stream worked perfect.

With current Version, only profiles with no limitations of Audio bandwith are working.
Debug output of a working profile:

And the profiles with Limitation of Audio, has no Audio. only Video ist transcoded. and Output bandwith is around 1500 kb/s, on Status page.

I think there's a bug in Setting libav Encoder Settings.
