Description Michael Smith 2008-12-17 22:32:57 UTC 
If the format changes while an audiosink is playing, a deadlock occurs.

To reproduce, use the playbin2 gapless test program: gst/playback/test7 with two files of differing sample rates.

When it gets to the 2nd file, it deadlocks - gstaudiosink.c:425 is trying to join the audiosink thread, but the ringbuffer is still running and will never shut down.
Comment 1 Wim Taymans 2008-12-20 12:44:50 UTC 
        * gst-libs/gst/audio/gstbaseaudiosink.c:
        (gst_base_audio_sink_setcaps):
        Pause the write thread before deactivating and releasing the ringbuffer
        to avoid a deadlock when we do gapless playback with different sample 
        rates in playbin2.  Fixes #564929.
