Adding new sources to compositor dynamically

[Kazanian]

Hi,

I'm using a pipeline with compositor plugin to combine several video
streams. It should be possible to add new streams dynamically, but when I
try to do that the videos freeze. It freezes with this call:

gst_element_get_request_pad(compositor, "sink_3");

The pipeline is still in playing state after this line. "sink_3" is a name
which does not exist yet in the pipeline. Is this function call the correct
way to add another pad? Do I have to call something else to get it running
again?

Thanks in advance for any help!
