audiomixer: issues with seamless looping (missing support for non-flushing seeks)
Submitted by Stefan Kost @ensonic
Link to original bug (#757563)
Description
Despite a test that should cover this in real world apps, audiomixer (aggregator) goes crazy when looping (gst_aggregator_do_seek):
I can play once with a segmented+flushing seek. When handling segment_done and sending another segmented seek (non flushing), I get this log forever, until I stop the pipeline.
