Your goal is to share the videos to any 3rd party websites and allow these websites to further share to others. The shared URL should lead the viewers back to your website. However, in some cases sharing could lead to an invalid URL, such as http://player.ooyala.com/iframe.html#ec=xxxxxx
This can be avoided by setting permalink for your video asset in Backlot. “permalink” points to the URL where your content is hosted at.
