Description Mathieu Duponchelle 2013-07-12 14:39:28 UTC 
The problems are most easily revealed by running make ges/mixers.check, 
an error will occur:

0:00:00.089797421  7467 0x7f9f980030a0 ERROR                basesrc gstbasesrc.c:1402:gst_base_src_default_alloc:<audiotestsrc1> Failed to allocate 4294967295 bytes

indicating audiotestsrc most probably didn't have its caps negotiated.

A similar scenario happens with videotestsrc as well, and I expect other problems from various elements.

    pad: A newly activated pad should be marked as needing reconfiguration

    Revert "pad: Don't consider flushing pads as needing reconfiguration"
    
    This reverts commit 948a9d2f2b728f5fb60be45d47a818cebeb60c7d.
    
    This is racy and trying to reconfigure and fail is still better
    than not trying to reconfigure at all.

    basesrc: Leave the loop function faster if we're flushing
    
    Especially don't even try to send stream-start event or try
    to negotiate.
