When no video element is displayable (visibility is hidden or display is none of the use element), audio level should be set to 0 and video should not be rendered. -Video1 should be displayed between 0-4s, not rendered between 4-6 s and displayed between 6-8s. -Video2 should be displayed between 0-2s, not rendered between 2-6 s and displayed between 6-8s. -The audio of the video should be muted between 4-6s as no video is then rendered.

If the user agent does not support the 3GP media format, the test is still a pass.
