Given that `content_id` is unique to each video (cf https://github.com/dragonfi/xblock-ooyala/blob/c08f51f3c7e9d56d473bd4bcfaa8b131412b23aa/ooyala_player/ooyala_player.py#L38 ), but not to each player of the video, that might cause problems if we try to load the same video several times on the same page. Not sure why would someone do this, but might be worth thinking if there is an easy differentiator we can have in these cases.
