MCVR: call VideoSink.setStreamTimestampInfo on stream change

Browse Source 
The start position and buffer adjustement are only allowed to change
when the stream changes so it makes more sense to call
setStreamTimestampInfo when the stream changes.

This is part of an effort to simplify stream change notification to the
video sink, to ease implementation of multi sequences preview.
