This talk gives a close look at second wave HTML5 features around video delivery — specifically, mediaSource API / adaptive streaming, encrypted media extension and WebRTC. We look at open tools and techniques for transcending platform limitations and delivery these experiences across increasingly diverse set of devices and platforms. Real world usage examples are highlighted from experience with open tools we have built and integrated. This presentation outlines real-world production usage of second wave HTML5 video features with a focus on technical integration into arbitrary application contexts and the trade offs for targeting a given feature set. We begin with a short review of challenges in the first wave of HTML5 video; codecs, consistent JS API and lack of unified adaptive streaming support standard. We then transition into HTML5 Part Dux and see how "the sequel" is a lot like the original with respect to a powerful new set of features but with equally impressive platform fragmentation and API inconsistencies. We highlight the compounded challenges of the entrance of additional mobile and smart tv platforms generating more device targets to support then ever before. We review open video platform solutions developed to bridge these limitations on native devices. Specifically we look at the technical architecture of a native video component that we have built to bridge android and iOS web view limitations in an native environment while seamlessly leveraging a feature rich HTML5 player platform. We also review the current state of mpeg-dash and highlight technical inconsistencies in implementation that drive the use of shared code libraries such as dash.js. We preset our production dash.js usage for VOD, Live and associated encrypted media extension options for content controls, along with technical implementation details to help inform integration options and trade offs. Finally we look to WebRTC and the types of experiences it can enable and how they can be delivered within the contemporary platform ecosystem. We look at technical approaches towards enabling usage and cross platform delivery options
