[theora] transcoding to theora from quicktime using xiphqt

[Nikolas Lam]

Hi,

I'm trying to convert some quicktime files into Ogg/Theora using the
Xiph QuickTime Components version 1.8.

The end goal is to stream these files using apache httpd and the cortado
applet (and hopefully the embedded players that will be in Firefox
soon).

Using iMovie DV on OS X 10.4.11 (intel) I'm able to export as an ogg
movie, however the resultant file has problems with audio on certain
platforms.

On cortado in Firefox (RHEL5, Fedora 9 and OS X), I just see what I
think is the first frame of the video and "Could not open audio device."
where the progress bar usually is. The video refuses to play.

On RHEL5's Movie Player, the video plays, but there is no audio at all.

On Fedora 9's Movie Player, I get a popup saying "Totem could not play
'/home/nik/rdob.ogg'. The audio device is busy. Is another application
using it?'

The file plays fine in VLC on OS X and Fedora 9.

How can I go about debugging this?
