    This is a media player that uses all the goods of HTML5 video/audio elements to play the most popular media in MP4/MP3, HLS and M(PEG)-DASH, and also has the ability to play VMAP, VAST and VPAID ads.


    Version 3.0 of this player just started to being worked on.

    As part of a continuous effort to improve the player, this new version will include, among others:

    • An increased unit test coverage (aiming to have at least 70%), including unit tests for all the demos.
    • Refactor of areas of code where creation of buttons for controls occurs, into a consolidated method to generate them.
    • Refactor of the main operations (load, loadAd, play, pause) to use Promises in a more clear fashion, and with that, execute more complex operations consistently, specially when dealing with loading dynamic content.
    • Better snippets/documentation to help users to configure OpenPlayerJS for their needs.
    • And more...

    Because of the refactor that will be performed in that version, support for IE11 will be dropped completely. Also, to support the effort of ending the IE11 life cycle, scheduled on June 15, 2022.

    So, please consider this before upgrading to any of the 3.x.x version going forward.


    • Supports IE11+ (Win8) and all modern browsers.
    • No dependencies, since it is written in Typescript.
    • Runs a simple but yet powerful algorithm to check the browser's autoplay capabilities across browsers.
    • Supports for local and remote captions for both video and audio, even without including the crossorigin attribute.
    • Enhance your player adding your own buttons. Check here for more details.
    • Provides the ability to use a single VAST/VPAID source or a VAST/VPAID playlist from several different sources (including URLs and valid XML strings).
    • Can play ads in infinite loop, desired for ads that are in a heavy text page.
    • Always responsive by default, for both video/audio tags; for video, fill and fit modes are available to either scale and crop media relative to its parent container, or to attempt to make the media fit its parent container (including black bars), respectively.
