Hello!

When I use ffmpeg to convert an audiofile with the option

-acodec libfaac -ab 192k 

and use

ffmpeg -i 

on that file afterwards to get the audio file information, it tells me

bitrate: 152 kb/s

Why ist this? Do I miss something here? If I want to convert a file with a bitrate of 192kb it should give me 192 kbit after the conversion, shouldn't it?

Or: How do I get the 192 kbit rate then?
