QuickTime Encoded date Error: gst-core-error-quark

[Carl Karsten]

I am trying to get the start and duration from a file (a few 1000 of them
once I get the first one working)

http://a-vinter.com/Capture0001.mov

import os

from gi.repository import Gst
from gi.repository import GObject
GObject.threads_init()
Gst.init(None)

from gi.repository import GstPbutils

pathname = "Capture0001.mov"
discoverer = GstPbutils.Discoverer()
d = discoverer.discover_uri('file://' + os.path.abspath(pathname))



    d = discoverer.discover_uri('file://' + os.path.abspath(pathname))
GLib.Error: gst-core-error-quark: Your GStreamer installation is missing a
