How the SeoChecker video caption audit fails

When <video> elements have no <track> element with the attribute kind=”captions”, SeoChecker will notify it.

 

How can I add captions to a video?

<video> element with the kind=”captions” attribute need minimum one track element.

<video width="300" height="200">
    <source src="marathonFinishLine.mp4" type="video/mp4">
    <track src="captions_en.vtt" kind="captions" srclang="en" label="english_captions">
    <track src="audio_desc_en.vtt" kind="descriptions" srclang="en" label="english_description">
    <track src="captions_es.vtt" kind="captions" srclang="es" label="spanish_captions">
    <track src="audio_desc_es.vtt" kind="descriptions" srclang="es" label="spanish_description">
