Who this affects
A video has no captions track. Deaf and hard-of-hearing users get no access to the spoken content, and captions are an explicit EAA expectation for media content.
How to fix it
Add a <track kind="captions"> with a real caption file. Auto-generated captions need review before they count.

Where this sits in the standard
| WCAG success criterion | Level | EN 301 549 clause |
|---|---|---|
| 1.2.2 Captions (Prerecorded) | A | 301-549, 9.1.2.2 |
EN 301 549 clause 9 applies these criteria to web content. The published version referenced by the European Accessibility Act is V3.2.1, which incorporates WCAG 2.1 level A and AA. More on the standard.
How to check it by hand
Turn images off in the browser, or run the page through a screen reader and listen to the image announcements. If you hear a file name, a hash, or nothing where something meaningful should be, the alternative is missing. Ask of every image: if this were removed, what would the reader need told?
Automated testing settles roughly a third of the WCAG success criteria. This rule is one an automated tool detects reliably — but a clean automated result is not proof of conformance.
