Description Sebastian Dröge (slomo) 2010-07-23 13:13:59 UTC 
Currently there's a race condition with the EOS events in gapless mode. If streams end at different times, the EOS of early streams could arrive the sinks before the next stream is selected, which will then cause the sink to not accept any new data.

I'll fix this in the next days in the new streamsynchronizer helper element

    streamsynchronizer: Delay EOS events until all streams are EOS
    
    This fixes a race condition in playbin2's gapless mode, where the
    EOS of other streams might arrive in the sinks before the last stream
    ends and the switch to the new track happens. The EOS sinks won't
    accept any new data then and playback stops.
    
    To prevent this, delay all EOS events until all streams are EOS
    and advance the sinks of the EOS streams by filler newsegment
    events if necessary.
    
    Fixes bug #625118.
