If it works with other files/file types, it's probably not your code.

It looks like nuvdemux in gst-plugins-bad just doesn't
extract/provide/estimate that information. I don't know if that's
readily available or easy to do, but maybe you could file a bug in
bugzilla, then someone will take a look at it.
