24-bit/96KHz LPCM audio

Hi,

I have an example of a DVD containing a 24-bit/96KHz LPCM audio track
which I have been trying to play under Linux.

Ogle (and vlc and mplayer) fail to correctly play this, but I propose to
add support to Ogle to fix this.

I have managed to hack ogle to correctly play the audio via OSS by
converting it to a 16-bit/48KHz LPCM stream inside the OSS driver.  I
also had to hack "conversion.c" so that it would pass the entire
(unmodified) stream to the OSS driver.

I want to handle the conversion from 24-bits to 16-bits and the
resampling from 96KHz to 48KHz separately.  Both 24/48 and 16/96 audio
streams are perfectly legal on a DVD.

As far as I can tell, there is no support for software conversion of 
LPCM streams to different formats at the moment.  Do other developers 
have any ideas about how this should be implemented?

I would also like to add support for 24/96 soundcards in the future 
(when I buy one!) and this would include using libmad's ability to 
output mpeg audio with 24-bit resolution.

I'm not proposing to do anything with 20-bit audio - it seems even rarer 
than 24-bit.

Regards,

Dave.
