Key features of this HTML5 video player solution
Acorn Media Player is built with accessibility in mind. It provides full keyboard control using standard tab-based navigation, screen-reader (and other AT) support, accessible themes, and other accessibility tweaks.
Along with closed captions support, the player provides a dynamic transcript generated from the selected captions.
This is yet no native support for closed captioning on HTML5 , but that shouldn’t stop you from providing them. It supports external SRT files just like desktop media players.
