Adding a note of something to try to fix this bug. When a new media-hub
Player instance is created and media has been set on it, try placing the
Player state into the paused state. According to this example [1], this
should be enough to get metadata out of it. Also, for players that
aren't played
@Pat: No, metadata and everything about a stream is not filled in until
you transition the GStreamer playbin pipeline to the playing state. So
there's no advantage to reading it from the metadata fields vs the
explicit duration field.

@jim could we also just read it from the metadata prior to playback? I
would think we already are somewhere.

Basically what we need to do is to see if GStreamer can update this
property/signal when prerolling which should happen when playbin is
first told to open a uri.

the onDurationChanged signal does work at least on an Audio component I tried.
Its called immediately after play starts, before you even hear anything.
Unfortunately that doesn't help with what I am trying to do.

Note we had a workaround for this within the music-app [0], this works
by running a query for the duration after the source has been set. I
wonder if this can be done internally in media-hub/qtubuntu-media and
once a valid value is found for it to be emitted up to the QML layer.
