Applicability
This rule applies to every non-streaming video element that is visible.
Expectation
The visual information of each test target is available through a text transcript that is visible, included in the accessibility tree, and is either on the page or linked.
Note: A "text transcript" in the context of this rule is defined in WCAG 2 as an alternative for time based media.
Assumptions
- This rule assumes that a mechanism is available to start the video and that the video element is not simply used to display the poster.
- This rule assumes that the language of each test target can be correctly determined (either programmatically or by analyzing the content), and sufficiently understood.
