I need to write a program on my Raspberry Pi to get a video and audio stream with Gstreamer from network and play them.(I have two stream. one for video and one for audio) and i need a custom GUI. I followed the below link :
http://www.jonobacon.org/2006/08/28/getting-started-with-gstreamer-with-python/
It used PyGtk and I want to switch to PyGObject. my question is : does PyObject support Gstreamer as well as PyGTK? or I should stuck to PyGTK? Or do you have a better solution to do that on Raspberry Pi
Considering the age of the article you linked, you might already know that there are newer versions of the libraries around. PyGtk and PyGst don't provide bindings for these.
Python GObject Introspection supports the Gkt-3.0 and Gst-1.0 versions. So you're safe using PyGObject for your program.
There's a quite good documentation on lazka.github.io/pgi-docs/ covering a lot more bindings as well.
Besides if you're going to build an audio/video player have a look at the
playbinelement. It's a complete pipeline supporting an audio-, a video- and a text-sink at once.
