Description Richard Hult 2005-03-06 16:40:37 UTC 
Create a pipeline with a decodebin, use it with an MP3 file and the when done,
unref the pipeline. The decodebin then tries to remove an element that is not a
direct child of it (in the remove_element_chain function).

The particular case I'm seeing is a id3demux element being removed from the bin,
when it is actually a child of another bin called id3demuxbin0.

The output is:

(process:5734): GStreamer-CRITICAL **: gst_bin_remove_func: assertion
`GST_ELEMENT_PARENT (element) == (GstObject *) bin' failed

Let me know if you need any more info.
Comment 1 Ronald Bultje 2005-03-07 16:36:01 UTC 
Can you provide a backtrace on that warning (to see where it's triggered;
decodebin->finalize? bin-->finalize?? sth. else?)

I think this should fix it. Not totally sure, I may be doing a typo something
in this hell of recursive behaviour...
