Hi,
the summary says it all, since 2.12.7, the variable didn't change while the
NEWS talks about added functions, some functions now have some defaults for
their parameters. I believe these should reflect in this variable like glibmm
does.

Gst::Element::get_factory() - Gst::ElementFactory refcount problem

gnomemm | gstreamermm | Ver: unspecified
Summary: Gst::Element::get_factory() - Gst::ElementFactory
refcount problem
Product: gnomemm
Version: unspecified
Platform: Other
OS/Version: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gstreamermm
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
QAContact: [EMAIL PROTECTED]
GNOME version: 2.23/2.24
GNOME milestone: Unspecified
Please describe the problem:
Gst::Element::get_factory() appears to currently be coded under the assumption
that callers of gst_element_get_factory() must unref the returned
GstElementFactory* when they are done with it.
However, this is not the case (according to the gstreamer
gst_element_get_factory() doco: "no refcounting is needed").
As a result, calling Gst::Element::get_factory() twice on the same element
causes the element's factory to be prematurely and incorrectly disposed.
Seen in gstreamermm 0.9.7 (and earlier).
Steps to reproduce:
Glib::RefPtr<Gst::Element> element =
Gst::ElementFactory::create_element("fakesrc");
{
std::cout << "Getting factory";
Glib::RefPtr<Gst::ElementFactory> factory = element->get_factory();
std::cout << "Factory name: " << factory->get_name();
}
std::cout << "Factory out of scope";
{
std::cout << "Getting factory again";
Glib::RefPtr<Gst::ElementFactory> factory = element->get_factory();
std::cout << "Factory name: " << factory->get_name();
}
std::cout << "Factory out of scope again";
Actual results:
Run with Debug logging enabled, and you should see the element's factory
incorrectly get disposed before the last out of scope message.
Not surprisingly, any subsequent calls to get_factory() on the element,
incorrectly return NULL;
Expected results:
The factory not to get incorrectly/prematurely disposed.
Does this happen every time?
Yes.
Other information:
I tried the a workaround that passes "true" as the take_copy parameter to
Glib::wrap(GstElementFactory*, bool) in Gst::Element::get_factory(), but for
some reason I'm not sure about, the refcount on the factory, after all the
RefPtr's to it were destructed, ends up being set to 2, rather than 1 like I
would expect (in the logging it shows that the first get_factory() call causes
2 refs to take place rather than just 1 - something to do with floating
references??).
I'm not sure what the correct solution is: Does there need to be a similar
approach to wrapping in get_factory() that is used for the get_structure() call
in Gst::Message? Or, something similar to the get_source() call in
Gst::Message??

So, Jos?, is this a WONTFIX? Or is there something we should want to do?

------- Comment #10 from Jos? Alburquerque 2008-11-04 18:33 UTC -------
I'm thinking it is a WONTFIX unless we decide to merge the gstreamerbasemm
branch into the gstreamermm branch. The gstreamermm and the gstreamerbasemm
branches exist because they are a reflection of the core and the
gst-plugins-base modules of GStreamer, but if it is convenient they can be
merged in gstreamermm. I can't modify the status of this bug, but if I had to
decide, I'd close it as a WONTFIX and suggest that it be re-opened in the
future if something else arises.
