This is required so that an a video module exported by one Open edX
deployment and imported by another will work correctly if it contains an
edx_video_id but does not populate other URL fields.

MA-77 Automatically adds the course id to the videos in VAL
when a course is rerun.

MA-169 Mobile api now calls for mobile_low (default), mobile_high,
 and youtube profiles instead of only mobile_low.

This is needed for courses that license video content where the license
allows only for viewing on the web, not on mobile apps.

TNL-1253 https://openedx.atlassian.net/browse/TNL-1253

Fix for MA-187 where a value error was thrown when
a course has a video directly under a section. This
PR handles the situations where a chapter or section
can be none, and then returns the appropriate url
if available.

This feature allows upload of video assets to S3. This requires that the
VIDEO_UPLOAD_PIPELINE setting be properly configured and that each
course be configured with a token issued by the media team for their
processing purposes (e.g. linking the video with a YouTube channel).
