The attached small patch provides somewhat more flexible
jack connections for mplayer, e.g.
mplayer -ao jack:dest=ardour:port="Audio 2"
willl make mplayer connect to the inputs of track "Audio 2".
You can also connect to e.g. system:playback_3,4 if you
set an alias for them first.
When used without 'dest', 'port' behaves as before i.e.
it selects an application. But the obvious way to do this
now is to use 'dest' of course.
Not a perfect solution but it helps.

Should that not go to the mplayer list? I'm not sure is any
of the mplayer devs are subscribed here.

Note that connections still could be wrong, since they are
based on the order in which jack lists the ports. Usually
this will be what you expect, but it's in no way ensured
by the API. For stereo the worst that can happen is that
L and R will be swapped. This will go unnoticed except
if you're listening to classical music. For multichannel
formats the result could be more of a pain.
It's not only an mplayer problem - most apps that auto-
connect to jack make the same assumption.

Yes, i was needing it :-)
mplayer is my jack favorite file player because it plays lots of audio
formats, multichannel, and does video!
In some occasions i need to connect to another jack-app or non-initial
hardware outputs. Actually i was doubting trying this hack or wrapping
mplayer with a script that redoes the connections.
I like he option in mplayer better -- and i'm also for promoting it to
the mplayer project.

Pau
