A Sink that outputs data to Jack ports.

It will create N Jack ports named out_<num> where <num> is starting from 1. Each port corresponds to a gstreamer channel.

The samplerate as exposed on the caps is always the same as the samplerate of the jack server.

When the ::connect property is set to auto, this element will try to connect each output port to a random physical jack input pin. In this mode, the sink will expose the number of physical channels on its pad caps.

When the ::connect property is set to none, the element will accept any number of input channels and will create (but not connect) an output port for each channel.

The element will generate an error when the Jack server is shut down when it was PAUSED or PLAYING. This element does not support dynamic rate and buffer size changes at runtime.

Example launch line

gst-launch audiotestsrc ! jackaudiosink

Play a sine wave to using jack.
