Something like:
from subprocess import Popen, PIPE
probe = Popen(("tcprobe", "-i", ip_file), stdout=PIPE, 
stderr=PIPE).communicate()[0]

or
from subprocess import Popen, PIPE
probe = Popen(("mplayer", "-identify", "-frames", "0", "-ao", "null", 
ip_file), stdout=PIPE, stderr=PIPE).communicate()[0]

First one uses transcode the second one uses mplayer. I normally follow 
these with a regexp search on "probe" for the data I want.
I have found mplayer to be more accurate than transcode which seems to have 
a problem with some files notably MPEG program streams although it seems to 
work fine for elementary streams.
