Bug 71: Video — Missing Captions (F8)

WCAG 1.2.2 (Captions Prerecorded) | Video with audio dialogue has no captions.

Failure F8: Video with Dialogue, No Captions

Issue: No <track kind="captions"> element. Deaf/HoH users cannot understand dialogue.

Failure F8 + Missing Description: Sound Effects Not Indicated

Tutorial video showing keyboard shortcuts with button clicks and transitions

Issue: Even if captions exist, sound effects (button clicks, alerts) may not be captioned.

Failure F8 + Invalid Caption Format

Caption file provided but in wrong format or not properly linked

Issue: Caption file doesn't exist, inaccessible, or VTT format not recognized.

HAL Fixes: HAL detects videos without caption tracks and alerts. If possible, HAL generates captions via speech-to-text or adds aria-label. HAL ensures <track> element is properly formatted and accessible.
