Applicability
This rule applies to every non-streaming video element that is visible where the video does not contain audio and contains a track element with a kind attribute value of descriptions.
Expectation
The visual information of each test target is described with a description track element that has the same language as the video or the same language as the page.
Assumptions
- A mechanism is available to start the video and that the video element is not simply used to display the poster.
- The language of each test target can be correctly determined (either programmatically or by analyzing the content), and sufficiently understood.
