rtspclientsink problem, it does not consume the stream or prevent pipeline going to the PLAYING state

Hi,

After upgrading the gstreamer to 1.8.0 my pipeline started to have problems. The pipeline has a webrtcendpoint source and a rtspclientsink to output the stream to a server. For some reason pipeline is getting stuck while switching to the PLAYING state. When i remove the rtspclientsink and replace it with a autovideosink it kind of works. I mean i normally set the pipeline to playing state and use gst_element_sync_state_with_parent function on each element. But with the autovideosink the videosink does not go to the playing state so i specifically set it to the playing state with a timer and then the pipeline starts to work as expected. Anyway the original pipeline should have rtspclientsink, with this element the behaviour is weird. I try to set the state to PLAYING and then check the state with gst_element_get_state and it never returns. Since rtspclientsink is not consuming the video after a while one of the queues in the pipeline get full and i start to get queue overrun messages. Below is the debug logs from rtspclient.

Any ideas how might be causing this and how can i solve it?

Thanks,
Ugur
