Description owen-bugs 2009-05-13 18:08:26 UTC 
Please describe the problem:
There is a quicktime reel of example shots from the RED camera linked from here: http://provideocoalition.com/index.php/mchristiansen/story/nab_2009_red_reel_online/

The url of the quicktime is: http://red.cachefly.net/redreel/RedReel_h264_720.mov

The audio plays back as an unintelligible hiss.

Steps to reproduce:
1. Download the file
2. try to play in totem
3. listen to the audio stream


Actual results:
I just hear a loud hiss

Expected results:
hear a proper sound track!

Does this happen every time?


Other information:
mplayer does play this file correctly, and the handy midentify.sh script reports this:

Totem's properties tab reports the audio codec as "Raw 24-bit PCM Audio", 48Khz, unknown bitrate

    qtdemux: parse in24 boxes to get endianness
    
    in24 samples are normally big-endian but an enda box can change this to
    little-endian. Recurse into the in24 box and find the enda box so that we get
    the endianness right.
    
    Fixes #582515
