<span>If you look at the debug logs (try GST_DEBUG=6), do you see
that all <br>
multiqueue pads are actually linked? Does it work better if you
use <br>
normal queues instead of a multiqueue? Does it work better if
you <br>
specify the exact pad names instead of letting gst-launch figure
that <br>
out? There is a bug with gst-launch that will cause linking to fail
