Using the example above, we can add in support for Flash by adding it as a last option: įor maximum compatibility it is advisable to include: Adding in support to fallback to Flash is straightforward. Flash FallbackĪ fallback to Flash should be included, as it allows you to embed video on browsers that may not support your video source types. Ī more in-depth discussion of types and syntax is available at Dive Into HTML5. If you do not specify the type field, the browser has to download a portion of each video until it can find one that it can successfully play. This tells the browser what the container type is, along with information about the video and audio codecs. It is important to specify the type field when embedding video. The browser will start at the first stream listed and go through all of them until it can successfully play one. Since there is no single codec and container combination that is supported across all browsers, you will need to specify multiple sources. Here’s how to add a video to your web app. More demos are available at .Īt its simplest form, an HTML5 video embed looks much like the audio example from above. Support for various video/audio codecs varies from browser to browser, so it is imperative that you plan for all potential browsers and devices when creating your web application.īrowser compatibility information for Ogg/Theora, WebM/VP8, and H.264 can be found at .Īpple has launched a site that showcases the possibilities of HTML5 Video. Similar to audio, the tag has been introduced in the HTML5 spec, allowing web developers to harness the ability to play video without relying on third-party plugins. Also, HTML5Rocks’ Playground has sample code to help you get started. Retrieve the filename and duration: audioElement.src įor a great tutorial with sample code that explains how to work with audio in the browser, see the ThinkVitamin audio tutorial. var audioElem = document.createElement('audio') ĪtAttribute('src', 'Crystal Castles - Untrust Us.ogg') In this example, we’ll add a song, jump to 30 seconds into the song, and play it. The API is very straightforward, and provides a robust way to control embedded audio. The HTML5 Audio Javascript API allows for programmatic control of loading and playing audio files. Both of them provide graceful degradation to handle non-HTML5 browsers. These libraries handle most of the inconsistencies around embedding audio, and let you focus on creating awesome web applications. Handling multiple devices and browsers is made easier by using a library such as Sound Manager 2 or Buzz. Unfortunately, despite the inclusion of the HTML5 tag, there is still some friction in embedding audio and having that work seamlessly across all browsers and devices. If the browser doesn’t support the audio element, then it will display the message, “Sorry, but your browser doesn’t support audio.” Helpful Libraries Sorry, but your browser doesn't support audio. The browser looks for the first mime-type it knows it can support.Ī simple implementation with only one source looks like this: Īn implementation with multiple sources looks like this: To get around the potential for codec incompatibility, HTML5 allows you to specify multiple source files. There is currently no single codec that plays across all browsers. The most supported codecs for playing audio in HTML5 are Ogg Vorbis, MP3, and Wav. HTML5 introduced tag, as well as the JavaScript APIs, which allow the browser to play audio without the need for an external plugin. In this guide, we’ll cover the various ways to embed audio and video, including browser compatibility and frameworks to streamline cross-browser compatibility. HTML5 has improved embedding of audio and video by providing native support for many different file types.
