This is still a known problem, as soon as one of the UDP sources is
unlinked, it'll post an error and -launch will stop. RTSPSrc should only

This is not true, -launch can link perfectly fine while playing.
however, you need to manually disable synchronisation in the sinks for
now (xvimagesink sync=0).
