python example

Doing a create/play/destroy cycle of playbin leaks memory. Using the new glib GObject "instance-count" and GtkInspector I see that each cycle leaks one GstGhostPad and one GstProxyPad; maybe that helps.

Python example attached.

Thanks for reporting. It should be fixed in git master

    playbin2: always unref the combiner sinkpad when removing the srcpad
    Create a function to do the pad cleanup of the GstSourceCombine struct
    and use it to not forget to also cleanup the sink pad and fix a memory
Comment 2 Christoph Reiter (lazka) 2014-12-10 17:47:16 UTC
Memory usage is constant now. Thanks!
