As that graph is from a pipleine in NULL state, it does not bring much
information to the issue. Maybe you could share a trace with
GST_DEBUG="*SCHED*:5", this way we could see the buffer flowing through each
elements, and see which sink does not receices any data.
Another useful point of information is a backtrace of all threads at the moment
of a stall. Studying were each threads are block can greatly improve the
understanding of the problem. If you cannot share that I would understand, so
let's hope this suggestion can help you.
