[gst-devel] gstreamer python

[Edward Hervey]

Hi,

  the programs exits straight away because you're not running a
mainloop. Look deeper at the examples in gst-python, you'll notice
they either do a loop of their own, or use a gobject.GMainLoop().

P.S. cc-ed on the gstreamer mailing-list, which is where these kind of
questions should be asked.
