Yuo can use gst.extend.discoverer

A python example:



import sys

import gobject
gobject.threads_init()

import pygst
pygst.require('0.10')
import gst
from gst.extend.discoverer import Discoverer


#
# NECESITA RELOJ PARA FUNCIONAR
#
def on_discovered(discoverer, ismedia, infile):
    print '\non_discovered:', infile
    discoverer.print_info()


if __name__ == '__main__':
    if len(sys.argv) >= 2:
        print 'ANALIZO: %s ' % sys.argv[0]
        discoverer = Discoverer(sys.argv[1])
        discoverer.connect('discovered', on_discovered, sys.argv[1])

        # The MainLoop
        mainloop = gobject.MainLoop()
        gobject.idle_add(discoverer.discover)
        mainloop.run()

    else:
        print 'Usage: %s <input_file>' % sys.argv[0]
