Description Alexey Chernov 2013-07-07 10:20:09 UTC 
Osxvideosink can't display video after it was once set to READY from higher states (PAUSED or PLAYING). Even after it was set to PLAYING again, it doesn't display the video stream anymore though it comsumps it successfully.

I seem to found the cause so I hope to prepare a patch with fix soon.
Comment 1 Tim-Philipp Müller 2013-07-07 10:55:14 UTC 
Great, what is the cause?

Is this the same as bug #703100 ?
Comment 2 Alexey Chernov 2013-07-07 11:09:18 UTC 
No, I don't think so.

In this case the cause is that gst_osx_video_sink_osxwindow_destroy() is called on state change to READY, which in turn calls -destroy() in GstOSXVideoSinkObject instance setting its 'destroyed' field to TRUE. All the further -showFrame() calls do a dry-run after that as 'if (!destroyed)' fails and GstGLView's methods aren't called.

But thanks for the reference, I'll pay some attention on the case with deadlock though I never saw it in my installation.
Comment 4 Alexey Chernov 2013-07-07 20:20:52 UTC 
Exactly, you're right. So that it's my installation was outdated, sorry.
