The sources will run as fast as possible; according to another clock for
a live source, as fast as the disk can read for a file. There is a
latency infrastructure for the live case. If your decoder syncs to an
external clock, it should implement a clock and export it to the
pipeline, and the sinks should be with sync=false.

Yes.

Cheers,

Andy.
