![]() The 'data-setup' Attribute tells Video.js to automatically set up the video when the page is ready, and read any options (in JSON format) from the attribute (see options). Note: The data-setup attribute described here should not be used if you use the alternative setup described in the next section. Beyond the basic markup, Video.js needs a few extra pieces. Video.js will then read the tag and make it work in all browsers, not just ones that support HTML5 video. With Video.js you just use an HTML5 video tag to embed a video. Step 2: Add an HTML5 video tag to your page. Additionally include the videojs-vtt.js source, which adds the WebVTT object to the global scope. Should Just Work™, but the paths can easily be changed by editing the LESS file and re-building, or by modifying the generated CSS file. If you simply copy the dist folder or zip file contents into your project everything To entirely self-host, you'll need to pull in the font files and let Video.js know where the swf is located. Install via package manager NPM $ npm install -save video.js If you'd like to disable analytics, you can simply include the following global before including Video.js: window.HELP_IMPROVE_VIDEOJS = false This allows us to see (roughly) what browsers are in use in the wild, along with other useful metrics such as OS and device. We include a stripped down Google Analytics pixel that tracks a random percentage (currently 1%) of players loaded from the CDN. Īlternatively you can always go here to get the latest URL for videojs CDN. ![]() In order to continue to support IE8, we've bundled an ES5 shim and sham together and hosted it on the CDN. As of Video.js 5.0, the source is transpiled from ES2015 (formerly known as ES6) to ES5, but IE8 only supports ES3. You can download the Video.js source and host it on your own servers, or use the free CDN hosted version. Step 1: Include the Video.js Javascript and CSS files in the head of your page. It can take a matter of seconds to get the player up and working on your web page. Once you have it working in some browsers, follow the instructions on the VideoJS documentation site to add the JavaScript and Flash assets to your server and reference them in your page. ![]() But you have to start with a properly constructed video tag that plays in some browsers before you can layer on the VideoJS to clean up all differences.įiddle with this basic shell until you can see something on the screen (all that you will need to change are the actual paths to the sources). The video tag is designed to paper over these browser differences, and all that VideoJS does is provide a Flash fallback if someone visits with an elderly IE browser. There's nothing Rails is doing or not doing at this level that will change that. All of them will benefit from a JPEG poster frame. You may need to fiddle with different browsers and formats at this point - Safari will play MPEG4 video, Chrome wants WebM, Firefox wants OGG or WebM. Don't include VideoJS yet, simply see if you can get a video to display on your page. First, put all the assets in the public folder, and hand-code a video tag on your page. It works pretty well, as long as all of the resources can be found and linked to one another. I haven't tried either of those gems, but I have used VideoJS long-hand in both static HTML pages and Rails. When I use js in line with html and place the library inĪssets/javascripts I get a blank black box as well. I installed the gem however the libraries are not showing. However when I use a link to a videofile on the web it works. When I go to the page nothing renders, just a black box. I have tried precompiling the video as an asset by placing in I have tried 2 different gems (github: seanbehan/videojs and I am trying to get videojs to play a local video file within rails.
