![]() ![]() Using HTML’s built-in fallback mechanism like this is the easiest way to start supporting HTML5 video. If the browser doesn’t support HTML5 video, it will fall back to that: You just put the exact same embed code that you use for your Flash player inside the video tag after the source tags. If you have a Flash player now, it’s pretty easy. Older versions of iOS would only look at the first source tag, and if it couldn’t play that source, it would just stop instead of looking through the rest of the sources for one it could play.įinally, for your users who have older browsers that don’t support HTML5 video, you can add a Flash player as a fallback. This can slow down the load process.Īnother tip is to always put the MP4 file as the first source. If you don’t include this, the browser will have to download a portion of each file to test whether or not it can support the format. The type attribute of the source tag tells the browser what format the file is it helps the browser decide which file to play. To add them, simply drop the “src” attribute from the video tag and add source tags inside the video tag: The three video formats primarily used in HTML5 video are MP4, WebM, and Ogg. The next step then is to add the other formats we need to support all HTML5 browsers. ![]() That’s already enough to get your video playing in many browsers, depending on the video format you’re using. The “src” attribute should have a URL pointing to a video that you’ve already uploaded to the web: When building your own HTML5 video player, your embed code will start with a simple video tag that contains a video source and the controls attribute to make the controls visible. Additionally, these libraries will often provide a common “skin” so that video controls look the same between browsers, which isn’t the case when just using the video tag. This is why you’ll see many JavaScript libraries (including Video.js) referred to as HTML5 Video Players. What we need is an additional JavaScript library that manages the selection of either Flash or HTML5 and fixes those bugs and inconsistencies. So using HTML5 is not quite that easy yet. However, not every user supports HTML5 video yet, and even within HTML5 video, there are bugs and cross-browser inconsistencies we need to handle. It allows us to simply use the video tag to embed a video. So what is an HTML5 video player? Technically, it is the player that’s already built into HTML5 browsers. That makes this a great time to get a head start on building video experiences with HTML5 video. Apple is holding strong on its decision not to support Flash on iOS, Adobe is cutting development on Flash for other mobile browsers, and more users support HTML5 video every day as Chrome takes over the browser market. That said, HTML5 video will some day be the default method developers use for playing video on the web. In order to work with HTML5, we need to know what its issues are and how to patch them. It has the potential to some day be a fully functioning HTML tag. HTML5 video is kind of like me at 6 years old. When I was 6 years old, I had metal-capped front teeth, a lazy eye, an eye patch to correct my lazy eye, thick glasses, plastic tubes in my ears to drain fluids, and a speech impediment.
