Nit: the final "else" isn't needed.

Ditto.

This looks *awfully* similar to updateAudioTracks. Is there any way to share code like MediaPlayerPrivateAVFoundation::processNewAndRemovedTextTracks does for processing in-band text tracks?

This should also test the "only one video track enabled" spec requirement.
