This code is confusing. I think you want to have a loop that walks up the tree, and to pull the tearDownVideoRendering() code out of the loop.

You should add a comment to say who listens for this notification. I also think you should use a more unique name than "CAContextChanged", since it would be easy to imagine CA adding a notification with the same name in future.
