Fix typo
Remove 'allow_sync = True' from CreateVideoClipObject (should be on the function that creates a list with videos).
Remove 'url' from VideoClipObject.
Set required rating_key (required if not using a URL Service).
If no extra http requests are needed, there's no need for a 'PlayVideo' function.
Declare variable types for non-string parameters 'container' and 'duration'.
