Description Matej Knopp 2011-11-24 06:35:24 UTC 
I want to resume building pipeline after queue element on notify::caps on queue srcpad, however this doesn't happen because queue doesn't start task until the source pad gets linked.

Queue should probably push the event to srcpad if the task is not yet started (or propagate the event somehow else)

The patch may require applying

    queue: remove weird link behaviour
    
    Remove the link functions and always start the pad task on the srcpad. If
    applications need to autoplug they can put a blocking probe on the srcpad like
    they would with any other element.
