Audio and video should be provided using an accessible media player. To support media accessibility features, including captions and audio descriptions, use a player with controls that are clearly identified and that can be operated using the keyboard (see the section on Interaction for general requirements).
- Do not use autoplay. Leave it to the user to decide when to play the media.
- Ensure that controls are keyboard accessible. This means all controls are operable using only the keyboard and do not require the use of a mouse.
- Support alternative formats. The media player should support captions and audio descriptions.
For every page that includes a media player:
- Does the audio or video start playing only in response to a user action?
- Are all of the controls reachable using the keyboard? Do they respond to standard keyboard commands? Is there a clear focus indicator?
- Does each control have a descriptive name? Is the current state of each control clear? For example, does the Play/Pause button convey whether the video is playing or paused?
- Can the player toggle the display of captions?
- Can the player play audio descriptions?
