gstreamer 0.10 to 1.0 and gtk2 to gtk3 errors

smo-3
hi list(s)

i try to port my app to gtk3/gst1.0 but have some errors i dont
understand i can post my code if needed but does someone have an idear
on the followings errors...

i post in pygtk and gst list but i have this crash since i used :

self.player.videosink = Gst.ElementFactory.make('xvimagesink')

Re: gstreamer 0.10 to 1.0 and gtk2 to gtk3 errors

Niklas Koep
I think a minimal program which reproduces the error would be helpful here. What exact versions of gstreamer, pygobject (python2-gobject), etc. are you using? In any case, calling Gst.ElementFactory.make with one argument from an interactive session already raises a TypeError exception for me as the method requires you to specify a unique name, as well as the element type. I guess default arguments aren't supported by pygobject yet which means you have to pass both 'xvimagesink' and None to the method for gstreamer to create a name for the element by itself.

Also, do you call Gst.init() before making any other gstreamer calls? I was under the impression this was called upon importing the module, but for some reason the interpreter complains about it if you don't explicitly call it. Weirdly enough according to the gstreamer-1.0 source g-ir-scanner is called with --add-init-section="gst_init(NULL, NULL);".

Re: gstreamer 0.10 to 1.0 and gtk2 to gtk3 errors

Niklas Koep
It appears I completely misunderstood the --add-init-section option of g-ir-scanner. It's only relevant for the creation of the introspection data. It's not a code section which gets called whenever the respective gobject language bindings (in your case pygobject) load a typelib. So in any case you have to call Gst.init() which you may or may not be doing anyway.
