IS IT THAT EASY TO BUILD A PLAYER?

» Reach all platforms/browsers» Not use plugins as far as possible» Parsing and handling all the different manifest types from

different vendors» Adaptation logic to choose correct quality» Live streams and on-demand streams» Synchronizing audio and video› Theoretically done by the MSE

» Subtitles and closed captions» Multiple audio tracks» Different HTML5 MSE/EME implementation on different

browsers» Virtual Reality / 360° playback» ...


PROPRIETARY ECOSYSTEMS WILL DISAPPEAR

Silverlight» One of the main platforms for DRM protected content in

the web in the past (via PlayReady + Smooth Streaming) » Is deprecated in Chrome and other browsers» Premium content provider need to switch

Flash» Significant security concerns » Starts to get blocked and deprecated» Proprietary DRM


OPEN ECOSYSTEMS ARE GOING TO WIN: HTML5 MSE/EME, DASH, HBBTV, ETC.

Browser Plugins will disappear » HTML5 is the major platform for media playback

Enabling technology: HTML5 Media Source Extensions HTML5 Encrypted Media Extentions

» Objectives:› Download media and construct streams in JavaScript› Decoding and rendering outside of JavaScript (e.g. in C/C++)› Specification is format and codec independent› Enables features like adaptive streaming and time shifting

» No more need for plugins (like Flash)


HTML5 MEDIA SOURCE EXTENSIONS

» Specification:› W3C Editor’s Draft since 26 June 2012› Latest version: W3C Candidate Recommendation 12

November 2015› Driven by Google, Microsoft, and Netflix› https://www.w3.org/TR/media-source/› Specification extends HTMLMediaElement› Allows JavaScript to dynamically construct media streams

for <audio> and <video> elements› URL is created from MediaSource object and is assigned to

the src attribute of HTMLMediaElements
