MSE gives us finer grained control over how much and how often content is fetched, and some control over memory usage details, such as when buffers are evicted. It’s quite an advanced solution if you want to make your video playback more customizable and professional. In other words, it allows JavaScript to generate streams and facilitate a variety of use cases like adaptive streaming and time-shifting live streams. Media Source Extensions is a W3C specification that allows JavaScript to send streams to media codecs within Web browsers that support HTML5 video and audio that most browsers implement today. But instead of streaming a video file through the “src” attribute inside of your tag, they use powerful tools such as Media Source Extensions or other adaptive streaming API that will help stream your video more efficiently. On YouTube, you can change the quality of your video, add subtitles, or even add features like autoplay if you have several other videos queued up and don’t want to switch it manually.Īll those services actually still use a video tag. However, most videos that we see on the web today such as YouTube, Twitch, or any other social media display much more complex behaviors than just changing playback speed or pausing the video. const myVideo = document.getElementById("#video1") Now we can use myVideo to programmatically pause, change the playback rate and current time of the video. Firstly, we need to access the DOM and declare an object which will be used for our manipulations. When you get an element from the DOM of a video tag, the object that you get exposes various methods and attributes which can be used for manipulating media content. You can also combine this simple video streaming in HTML with JavaScript and make it more professional and be able to control your streaming manually. To handle the case of browsers not supporting the video tag you can provide fallback content inside the tags. In addition, there are video-specific properties such as whether the video should loop or autoplay and whether to display the default browser controls. It embeds a fully-fledged media player in the document and similar to the img tag accepts a path to the media we want to play inside the src attribute as well as accepting parameters for width and height. You can easily start streaming your own video by using only one tag in HTML5. Streaming video inside of your web application nowadays is a breeze. Now we have HTML5 and new versions of JavaScript, and by combining these two new technologies you’ll end up with results that rival native applications. So to stream your video inside of your browser you were forced to use some third-party services like Flash or Silverlight. Because back then HTML was much simpler and didn’t even support video playback. If you would tell someone from the early 2000s what you’re about to do, they would be amazed and would give everything to understand how you did it.
