DRM Fallback Example

Below is an example of Vimeo video with DRM in a cross domain iframe. The issue we're seeing is that on a device that is not connected to an HDCP monitor, HDCP restrictions are being applied several seconds into playback. This occurs on Chrome only. It does not occur when the video is loaded outside of a cross domain iframe.

How to reproduce issue

1. View the video on a device that is not connected to an HDCP monitor
2. Open the "Debug Panel" by pressing the "d" key (click in the iframe to allow it to capture keyboard presses)
3. Verify DRM is enabled (DRM: true / default)
4. Verify the current quality is above 720p
5. Play the video
6. Observe that after several seconds, it will switch to "fallback" DRM (DRM: true / fallback)
