Adobe Flash was necessary to add a video to an HTML page before this time.įlash leveraged the RTMP protocol to deliver video data from a server or CDN to a user’s web browser. Opera proposed the video element of HTML in 2007, which was implemented in HTML5. Why HTML5 Is NecessaryĪs mentioned previously, HTML5 video came to be a more secure and functional replacement for Adobe Flash. By continuously monitoring a user’s bandwidth and buffer levels the HTML5 player identifies which of the available renditions of the stream will provide the best experience and selects that for viewing. This process ensures all your viewers have positive playback experiences regardless of device type or network performance. Presenting downloaded segments to MSE for decoding and rendering on-pageĪdaptive bitrate streaming support is a significant feature that makes an HTML5 player necessary.
What Do HTML5 Players Do?Īn HTML5 player handles every detail for connecting to a stream, including: This API, combined with Encrypted Media Extensions (EME, for features like enhanced security and DRM), and VTTCue (for subtitles) allows developers to use JavaScript to override how browsers handle video tags and improve streaming video delivery. Preventing these mishaps and ensuring a better viewing experience (for both live and on-demand streaming) requires a separate player component, the HTML5 streaming video player.Īt its core, an HTML5 player is a JavaScript package that uses the Media Source Extensions API, or MSE. The built-in video elements provide only limited control over how a browser loads and plays video, often resulting in stalling and buffering. However, these tags only support embedded videos, not streaming. Web browser developers have added video playback functionality into their browsers like Safari, Google Chrome, and Firefox, allowing other developers to add videos to web pages the same way they can with images. You already know that HTML refers to Hypertext Markup Language - the language that composes every page on the internet - but the 5 indicates the latest version of HTML that supports video and audio tags, like so: and.
