Is Videojs open source?

JS is an open-source JavaScript video player. Video. js is an open-source HTML5 video player that uses JavaScript and CSS to offer a consistent experience across browsers.

Does Videojs support audio?

Audio tracks are supported in Video. js's MSE playback engine for HLS and DASH. Safari also supports audio tracks for native playback of HLS and MP4. Other browsers do not support audio tracks for native playback including MP4, so it is not possible to work with MP4 audio tracks in Chrome or Firefox for example.
