How can I find out the audio bitrate from a video?

[mgpg89]

I have a video and I'd like to know what the audio bitrate is..
The properties window only shows the total bitrate (audio + video)

Thanks in advance

If you have the command-line tool "ffmpeg" installed, just enter

ffmpeg -i [i]filename.mp4[/i]

This is what I get (shortened for space reasons):

$ ffmpeg -i Wipeout.m4v

[mgpg89]

can't work out how to do it with the ffmpeg file ... any other (more simple) way?

VideoSpec (I prefer that, though it hasn't been updated since 11/2009), MediaInfo Mac (10/2010) or MediaInfo (10/2010, there is a Mac OS X version to download, VideoSpec and MediaInfo Mac are using the same library as MediaInfo)

Quicktime 7 Pro has this feature. You can go into movie properties and get information on each track specifically.
