Opus encoder with channels=8 and mpegtsmux is not working
Pipeline: gst-launch-1.0 v4l2src device=/dev/video0 io-mode=4 num-buffers=3600 ! video/x-raw, width=3840, height=2160, format=NV12, framerate=60/1 ! omxh265enc gop-mode=basic gop-length=60 b-frames=0 target-bitrate=60000 max-picture-size=1100 num-slices=8 control-rate=constant prefetch-buffer=true low-bandwidth=false filler-data=true cpb-size=1000 initial-delay=500 ! video/x-h265, profile=main, alignment=au ! queue max-size-bytes=0 ! mux. alsasrc device=hw:1,1 ! queue ! audioconvert ! audioresample ! audio/x-raw, format=S16LE, rate=48000, channels=8, layout=interleaved ! queue ! opusenc ! opusparse ! queue max-size-bytes=0 ! mpegtsmux name=mux ! filesink location="/run/test.ts"
Above pipeline is not working, However if channels=7 it is working.
Below are GST_DEBUG=3 logs of the pipeline:

But, channel-positions is expecting GValueArray type input, so how can we provide that I am not sure.
Also not sure, if any other particular fix required in pipeline.
