When I see the following messages in gstreamer log:

2:46:50.535363829  7547      0x155d2d0 WARN                GST_POLL

I have a 100% cpu usage, probably the client disconnect and cause this
behaviour. Setting the pipeline to NULL state make the cpu usage return as
normal. This seems an infinite loop.

My pipeline is something like this:

rtspsrc .. ! *pay ! mastroskamux ! multifdsink
