Hi,

I try to connect to an rtsp server with 16 rtspsrc. When I change them to
PLAYING one at a time, everything is fine. But when I try to change all of the
source's states to PLAYING simultaneously, only 10-12 of them start receiving
rtp data, the rest goes to timeout. The sources are in different pipelines (1
source per pipeline).

I made the test with a shell script like this:

gst-launch rtspsrc location="..." timeout=30000000 ! rtph264depay ! h264parse !
ffdec_h264 ! xvimagesink & 
gst-launch  rtspsrc location="..." timeout=30000000 ! rtph264depay ! h264parse
! ffdec_h264 ! xvimagesink &
gst-launch  rtspsrc location="..." timeout=30000000  ! rtph264depay ! h264parse
! ffdec_h264 ! xvimagesink &
...
...

The locations are different for each rtspsrc. I think it's a kind of thread
problem because in one test case 10 source can start, in other 11 or 12 (it's
random). 

If I put the rtspsrcs into one pipeline, and set the pipeline's state to
PLAYING, it's works too, but in this case the sources aren't start
simultaneously.

Any ideas? 

Regards
Tibor
