I haven't sent in my new patch, but I was going to port over the code 
from mplayer.  It's very nice code, doesn't have any external 
dependencies (unlike the bio2jack version I posted before) and it 
handles multi-channel

When I last looked at Chris's code it only handles the case of a two 
channel audio setup?

Anyway, there is no magic here - the mplayer code simply sets up a small 
ringbuffer and runs a callback to feed the data to jack on the 
callback.  I tuned it a little to add some timer code so that you can 
get an estimate of the current sample pointer (which improves smoothness 
of the video in mplayer).  The mplayer code only accepts floats as input 
data and I would add a simple volume control by scaling the samples in Xine.

I am snowed under at the moment, but intended to put something out a 
long while back

My suggestion would be to stick in anything which is written right now 
so that at least we have something.  Chris and I can perhaps fight out 
the details if I produce an alternative library and then it will just be 
a cut and paste if he agrees that my code looks better in some way... 

However, better to release something I think.  I have had quite a lot of 
interest in using digital filtering via Brutefir and Jack is the perfect 
way to implement this.
