The first caps on one of the sinkpads will set the caps of the output so usually an audioconvert element should be placed before every sinkpad of interleave. It's possible to change the number of channels while the pipeline is running by adding or removing some of the request pads but this will change the caps of the output buffers.

In order to use gstreamer -backend with an external render extension, 'appsink' needs to be used rather than 'xvimagesink', or any other sink. The gstreamer -backend -e option works by looking for an 'appsink' element named 'video-sink', which it will find and setup properly with the appropriate callbacks, etc for data to render to the storyboard
