Description Tim-Philipp Müller 2008-08-26 15:28:32 UTC 
#!/usr/bin/python
import gobject
gobject.threads_init()
import gst

c = gst.Caps('foo/bar')
for s in c:
  c2 = gst.Caps()
  c2.append_structure(s)

gives a:

(foo.py:31165): GStreamer-CRITICAL **: gst_caps_append_structure: assertion `structure->parent_refcount == NULL' failed

warning.

You could argue that it's the caller's responsibility to make sure the structure is writable and all, just like in C, but I think this is python and it should Just Work, no?

	* gst/gstcaps.override:
	Override gst_caps_append_structure() and make a copy of the structure
	given as argument.
	Fixes #549450
