[MPlayer-users] Quicktime 7.1.5

[Sean Montague]

I needed to refresh my memory a bit. I'm not a QT guy, I just convert 
them to flv. Apple released a security update on March 5th, 2007, 7.1.5. 
The problem is that mplayer can no longer read the ID_AUDIO_BITRATE, see 
blew. For me this is a problem since I use ID_AUDIO_BITRATE to determine 
how big the audio file is, which allows me to infer what the in video 
bitrate is. When I convert the files my goal is to maintain, as best as 
possible, the original size and quality. Notice ID_AUDIO_BITRATE=1536000 
below. I'm told by the fella creating this file that this is absurd. 
Anyway, the mencoder I'm using on RedHat is current as of early February 07.
