Wrong bitrate information on produced .mp3 when using default options

Description (last modified by cehoyos)

What i try to do: I am trying to get the audio stream from a .flv and save it as .mp3 (using default options)

Problem: When inspecting the output file with VLC media player, it shows a bitrate of 64 kB/s. As far as i read, default bitrate from ffmpeg should be 128kB/s, which also fits the actual file size.

Consequence: When using the file in a HTML <audio>-Tag, some browsers (Internet Explorer, Safari) estimate the duration double as high as it actually is.

Command line only specifies input and output file like

ffmpeg -i input.flv output.mp3

Additional Information: This problem does not occur when explicitely setting the bitrate with '-b:a 128k'.
I tried this with several .flv files, also one from the web (http://www.mediacollege.com/video-gallery/testclips/barsandtone.flv) and also with a .mp3 file
