Can you leave this as a pure virtual?

I could, but then it needs to be implemented in VideoBroadcaster instead, since
that class is instantiated as a member of VideoCapturer and VideoRtpReceiver
(none of which wants a real implementation). The implementation which matters is
the one in VideoCapturer itself.
