The PyGI API works pretty much exactly like the C API, the only thing
where it's a bit different is when there are 'out' arguments (like &pad
here) in the C API, then you might get a tuple with multiple return
values in python.

Try something like this (untested):

from gi.repository import Gst
#wait for state change to finish, but max 5secs
print caps.to_string()

I'm sure you can find a pygi tutorial somewhere so you don't have to
stab in the dark any longer.

On the python interpreter command line you can also do


to see what methods are offered.
