Accessible Video Library


Accessible Video Library solves a problem in WordPress: the ability to manage videos and manage critical associated media including captions, transcripts, and subtitles for each video.

In WordPress 3.6, WordPress incorporated the MediaElements.js library for showing videos. It’s a good library, and includes native support for captions and internationalization, is keyboard accessible, and supports YouTube.

However, the WordPress implementation doesn’t provide any method to add captions, subtitles, or reference YouTube videos. You can always embed YouTube videos using oEmbed, but these videos don’t have much at all in the way of keyboard support.

Accessible Video Library gives you a custom post type that you can use to manage your video media. You can upload captions in .SRT or .DFXP format, upload subtitles also in .SRT or .DFXP format, use the content of the post to include a video transcript, and can reference YouTube videos.

Additionally, you can upload multiple formats of your video files to improve browser compatibility for your videos.


Available languages (in order of completeness):
German, Portuguese (Brazil), Polish, French, Dutch

My transcript links go to a 404 error. How can I fix that?

Go to Settings > Permalinks and update your permalinks format — the issue is that the permalink format for AVL isn’t being understood by WordPress, and needs to be registered.

Hi, This plugin is the only one that I could find to play videos with subtitles. I tested more than five plugins that claimed to support subtitles but this one is the only one that worked. It plays videos from external server as well as local, but subtitles only work when they are on the local server (the don’t work from external server which is not important for me). It would be great if some more features are added, especially video auto-play by loading the page. Regards, Soheil
