Summary of Issue: 3rd Party Content - Embeded Video Player
Comment (Including rationale for any proposed change):
This is a question from WAIC(Web Accessibility Infrastructure Committee in Japan) which is a successor to JIS working group. In order to harmonize with WCAG 2.0, we need an answer from WCAG working group.

A video player is embedded in a web page. The author used the third party video player to present video-audio content(synchronized media).

In this case, are the UI components of the video player also applied to "Statement of Partial Conformance - Third Party Content"? The UI components include "Play/Pause", "Stop" buttons, volume controls and so on.

- Video-Audio content is under the author's control.
- But UI components are "uncontrolled content" which is not content that is under the author's control.
- UI components may be updated without notice. After the update, even if UI components won't meet SC anymore, it is not under the author's control.

One of the specific examples for this situation is YouTube player APIs. There are many web pages which embed video-audio content by using Youtube Player. UI components of Youtube Player are not under author's control.

In my understanding, "Statement of Partial Conformance - Third Party Content" is only applied when it is not possible to know at the time of original posting what the uncontrolled content of the pages will be. So, in the case of Youtube palyer, it is not applicable. But I'm not sure...

We've got many questions on this point. In order to keep international harmonization between WCAG and JIS, we have to confirm WCAG's rationale.

Proposed Change:
Quick answer would also be helpful. Thank you very much for your cooperation.
