[gst-devel] multichannel audio with jacksink

[Tristan Matthews]

I'd tried something like that before, and it yields the following errors:

cannot deliver port registration request
ERROR: from element /pipeline0/jackaudiosink0: Could not get/set 
settings from/o
n resource.
Additional debug info:
gstjackaudiosink.c(564): gst_jack_ring_buffer_acquire (): 
/pipeline0/jackaudiosi
nk0:
Cannot allocate more Jack ports
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
/pipeline0/jackaudiosink1.sink: caps = NULL
/pipeline0/audioconvert1.src: caps = NULL
/pipeline0/audioconvert1.sink: caps = NULL
/pipeline0/audioconvert0.src: caps = NULL
/pipeline0/audioconvert0.sink: caps = NULL
/pipeline0/audiotestsrc1.src: caps = NULL
/pipeline0/audiotestsrc0.src: caps = NULL
FREEING pipeline ...

I think I might have to combine the audio into one 8 channel stream 
before piping it to the jackaudiosink, as it doesn't seem to work with 
multiple jackaudiosinks, however I'm not sure how I'd do this either.
