We need to be able to handle this, but it doesn't have to be clean - timeshared
channels (e.g. BBC THREE/BBC FOUR and CBBC Channel/CBeebies) is the use-case.
We can thus cope if GStreamer simply throws an event at us to say that things
have changed and we need to restart.

For background: the BBC (and many other broadcasters) share an encoder between
two stations. At 7:00pm, it stops encoding one station and starts on the new
one, resulting in a PTS discontinuity, as the new station will switch from
playing out a static loop to playing the encoder's output, and the old station
will switch from the encoder's output to a static loop. We don't need to follow
the switch, but we do need to stop playing and not follow the encoder to its
new service.
