Re: playing video without audio

It possibly would need audio descriptions, not audio captions. Captions are
for hearing impairments, so since there's no audio, there's nothing to
caption. Audio descriptions are for people with visual impairments, since
there's no audio, it has no value to them. Depending on the specifics,
there may need an audio track or transcript provided.
