Testprogram

If I run the attached program on a bunch of media files it sometimes is missing
the state-change callback from READY to PLAYBACK. No error callback is given in
that case. 

It most notably occures on flac files, i.e. I can reproduce it perfectly when
passing the same flac file twice on the commandline, but also passing an oga
and a flac file hangs quite reliably, though I had it also hanging on JPEG
files.

Using the same program with the gstreamer libraries of Ubuntu 9.04 does not
show this behaviour (0.10.22)
Comment 1 Jens Georg 2009-09-23 16:40:38 UTC 
I forgot: not using the fakesinks also makes the state change appear.

Jens, if you are interested in metadata retival, please also consider trying the patches in bug #564749.
Comment 3 Tim-Philipp Müller 2010-02-28 20:47:39 UTC 
Jens: does this still happen with the latest GStreamer releases? (Or ideally, the current pre-releases as per GStreamer PPA)

I can't reproduce this with current git/prereleases at all, using your test program.
Comment 4 Tim-Philipp Müller 2010-02-28 20:51:33 UTC 
Also: you don't ever seem to set playbin back to NULL or READY state after it prerolled and you got your tags - is that really what you want? I'm surprised that worked at all for multiple files..

line 26: gst_element_set_state (playbin, GST_STATE_NULL);

I will check if it still occures
Comment 6 Jens Georg 2010-03-21 12:03:12 UTC 
Seems to be gone. Does not occur on debian unstable or on git master
