Accessible HTML5 media player
This plug-in uses Able Player, an open-source fully-accessible cross-browser HTML5 media player, to embed audio or video within your WordPress page.
There are currently two ways to add an Able Player instance to a WordPress site:
Enter or paste any valid HTML5 Able Player code into your web page. Full documentation is available on the Able Player project page on GitHub.
Enter an [ableplayer]
shortcode. The shortcode is intended for adding videos hosted on YouTube or Vimeo, with captions and subtitles hosted on these services. For anything more complex, use HTML.
The [ableplayer]
shortcode supports the following attributes.
youtube-id
– 11-character YouTube ID or YouTube URL.vimeo-id
– Vimeo ID or URL.youtube-desc-id
– YouTube URL or ID of a described version of the videovimeo-desc-id
– Vimeo URL or ID of a described version of the videoyoutube-nocookie
– “true” or “false” (use “true” to embed YouTube untracked, for added privacy)id
– a unique id for the player (if omitted, one will be automatically assigned)autoplay
– “true” or “false” (default is “false”)loop
– “true” or “false” (default is “false”)playsinline
– “true” or “false” (default is “true”). By setting to “false”, some devices (e.g., iPhones) will play the video in their own media player rather than in Able Player.hidecontrols
– “true” or “false” (default is “false”). Set to “true” to enable the player controls to fade away during playback. They will appear again if the user hovers over the player or pressing a key, and they are always accessible to screen reader users.poster
– the URL of a poster image, displayed before the user presses Playwidth
– a value in pixels (by default, the player will be sized to fit its container)height
– a value in pixels (by default, the height of the player will be in proportion to the width)heading
– The HTML heading level (1-6) of the visually hidden “Media Player” heading that precedes the player (for the benefit of screen reader users). If omitted, a heading level will be intelligently assigned based on context.speed
– “animals” or “arrows” (default is “animals”)start
– start time at which to start playing the media, in seconds. Some browsers do not support this.volume
– “0” to “10” (default is “7” to avoid overpowering screen reader audio). Some browsers do not support this.seekinterval
– number of seconds to forward/rewind with the Forward and Rewind buttons. If omitted, the interval will be intelligently assigned based on length of the video.nowplaying
– “true” or “false” to include a “Selected Track” section within the media player (default is “false”).This example uses HTML to add an audio player to the page, with one source (an MP3 file).html
<audio id="audio1" preload="auto" data-able-player src="path_to_audio.mp3">
</audio>
This example uses HTML to add a video player to the page, with one source (an MP4 file) and four tracks (for captions, descriptions, and chapters in English; and subtitles in Spanish).html
<video id="able-player-1" data-able-player preload="auto" poster="path_to_image.jpg">
<source type="video/mp4" src="path_to_video.mp4">
<track kind="captions" src="path_to_captions.vtt" srclang="en" label="English">
<track kind="subtitles" src="path_to_subtitles.vtt" srclang="es" label="EspaƱol">
<track kind="descriptions" src="path_to_descriptions.vtt" srclang="en">
<track kind="chapters" src="path_to_chapters.vtt" srclang="en">
</video>
This example uses a shortcode to add a YouTube player to the page, with two versions of the video, one with audio description and the other without (the user can toggle between the two versions using the D button).[ableplayer youtube-id="XXXXXXXXXXX" youtube-desc-id="YYYYYYYYYYY"]
This example uses a shortcode to add a Vimeo player to the page, with two versions of the video, one with audio description and the other without (the user can toggle between the two versions using the D button).[ableplayer vimeo-id="XXXXXXXXX" vimeo-desc-id="YYYYYYYYY"]
