This wiki explains how to use public & external videos(Google Drive, Youtube & local etc.,) in ECML content.

Background:

...

Currently, the creator can add a video into an ECML content by adding a Youtube URL/Google Drive URL.

1. If public & external video removed from the source it is getting removed from the content as well. (ECML content is still referring the external source so it is not playable).

2. Support to add local videos to ECML.

Key Design Problems:

• Create a streaming URL for videos

• Google drive URL asset when we are creating

• Backward compatibility

• Migration

Design:
