Support for audio description in Totem?

[John Robinson <jbr100uk gmail com>]

Hi everyone.  I'm totally blind and enjoy watching tv on my PC using a 
Hauppauge USB tv stick and Totem.  I use this on Ubuntu 10.04 with Gnome 
and the Orca screen reader.  I find Totem very easy to navigate with a 
screen reader and it currently does pretty much everything I need.  One 
feature I really would like to see in Totem, however, is support for 
audio description.

Audio description is an extra soundtrack containing a voiceover which 
describes what is happening on the screen.  The main programme 
soundtrack is usually displayed in Totem's 'Languages' menu as 
'English#1' or 'Audio#1' and the audio description track is usually 
displayed as 'English#2' or 'Audio#2'.  At the moment, Totem can play 
either the main programme soundtrack or the audio description 
soundtrack, but not both.  In order for the audio description to be 
useful, it needs to be played alongside the main programme soundtrack.  
What are the chances of implementing this feature in future versions of 
Totem?  I regret that I am not a programmer, but would willingly test 
this feature if anyone is able to implement it.

I very much look forward to any comments on this.

Regards,

John
