help needed for for IP Camera switching using mutliqueue gst element

[Janardana Dasa]

Hi,


I wrote code for dynamic pipeline where i have multiple ip camera connected
to multi queue element
and I am connecting only one srcpad of multiqueue to rest of the pipeline
if it is active camera at that particular timestamp. Other srcpad of
multiqueue is connected to fakesink.

Now the problem is code works when i switch camera to camera but it hangs
randomly giving below error:

Please help to solve it. It seems a bug in multqueue which causing
this race which is beyond my knowledge.
