Gstreamer and Python on the Mac

[Jack Jansen]

Andoni,
thanks for your note. I had indeed in the mean time found out that gobject-introspection is available nowadays, only that it is disabled if you do a universal build.

I’m looking at that, and if I have anything to contribute I’ll do it through the bug tracker.

Regards,
Jack

I’ve been using this for over two years in various projects, along with a couple of friends, and it works just fine. The bad news is that I started this 2 years ago based on the gstreamer.com <http://gstreamer.com/> fork, and my attempts to feed back these fixes into the mainstream went nowhere. This may well be because I wasn’t aware of the differences between the gstreamer.com <http://gstreamer.com/> community and the gstreamer.freedsktop.org <http://gstreamer.freedsktop.org/> community and contacted the wrong people, I don’t know. But anyway: so far my mods haven’t seen wide adoption.

For example, I have a mod to the gtk build process that is needed to expose NSViews from widgets so they can be used for GStreamer rendering from Python. The cerbero recipe for gtk builds from a tarball, should I add a patch, or should I build gtk from a forked git repository? Any help on how I feed this back to the Btk developers?
