After some discussions on IRC I have a plan to check if caps have changed and
not change things if the caps are the same.  I also think I've worked out what
is going wrong - basically the caps change due to working out information about
the actual video being passed through which causes a caps event to pass up
stream - clearing the rtpptdemux payload type map.  The next packet to go
through then causes the rtpptdemux to get the caps and send them back
downstream - they are the same caps but it breaks the video codec.

By checking if the caps have changed and avoiding destroying the decoder's
state or rtp payloader's state in the case where they are the same I can ensure
the stream starts reliably.
