Alternative for time-based media (multimedia)

All time-based media includes clear audio descriptions or other media alternatives (e.g. transcript, description)


Missing transcript:

This multimedia <video> element has no transcript (media-alternative):


(This violation triggers both 1.2.3 and 1.2.5 because transcript and audio description is required for 1.2.3; and 1.2.5 requires audio description as well.)


This is a test sample video with on-screen text and background sound.

Note: Impossible to implement, as it's requires AI / human to check all possible places where transcript could be located (below audio, details / summary, iframe, downloadable file, aria-labelledby)
