你是否一直在和一个CDN约会，感觉就像永远? 虽然一夫一妻制可能有利于人际关系, 当涉及到流媒体交付时，它可能会带来很多风险. 随着CDN交付继续变得更加商品化, working through the solution to have an intelligent multi-CDN solution in place is critical for widespread critical delivery at scale. This session dives into the options, providers, and solutions and examines how and what to consider. It also shares some of the “gotchas” around security and implementation that need to be accounted for in the client and infrastructure, 以及如何用先进的概念把它带到下一个层次.

随着2020年“Flash的终结”即将到来, 你需要使用共同的标准来达到所有的目标受众. 对于那些在网络浏览器中提供实时视频的人, HTML5 has had plenty of time to play catch-up and surpass Flash capabilities— or has it? In this session, 从HTTP中学习哪些传输技术(或其组合), WebRTC, RTSP, 甚至RTMP效果最好, when to use them, 以及如何投入开发资金以获得最大回报.

Per-title encoding techniques customize the encoding ladder to match the encoding complexity of the source, saving bandwidth on easy-to-compress videos and ensuring the quality of more complex footage. 编解码器专家Jan Ozer比较了效率, implementation issues, and costs of multiple commercially available and open-source alternatives for live and VOD per-title encoding. Learn what per-title encoding is, how the various options work, and which is the best option for you.

A good packaging strategy can bring numerous key benefits to your operational flexibility. This session asks panelists to talk about their own packaging challenges and strategies and looks at how the emergence of dynamic packaging can provide significant operational cost savings as well as higher levels of security and flexibility as audiences evolve and change.

While H.264在过去十年中一直主导着流媒体, 市场正在转向新一代的编解码器，比如VP9, HEVC, AV1, and VVC—as well as proprietary codecs—that offer significantly better compression but much more fragmented support in browsers and devices. This roundtable discusses how savvy businesses can migrate to the new technology and get the benefits of more efficient compression without sacrificing audiences.

拥有合适的工作工具可以让你更聪明地工作，而不仅仅是更努力. Developing for and supporting some of the biggest live streaming events such as the Super Bowl, Olympics, 和世界杯需要加强和完善我们带来的工具库. 本节讨论了必须具备的监控工具, debugging, identifying, and solving problems quickly and effectively for live and on-demand streaming content. 这些工具包括免费软件, opensource solutions, paid products, 以及RealEyes将与社区分享的一些定制工具. We discuss some of the gotchas and key issues to look for when dealing with major events—how to spot them and what to do on-the-fly when you have only one shot to get it right.

Open source tools like FFmpeg and Bento4 are used to build massive encoding farms for high-profile premium content services, but they also serve wonderfully as simple tools for smaller developers and can deliver significant functionality with minimal programming. 如果您可以在Windows上编写批处理文件，并且可以访问Linux机器, you can learn to encode and package an encoding ladder to HLS/DASH with captions and encryption and to set up a simple watch folder for drag-and-drop operation.

The NOAA Office of Ocean Exploration and Research is the United States’ only federal organization dedicated to exploring the global ocean. Our main research ship, the Okeanos Explorer, live-streams its deep-sea explorations via satellite for scientists and the general public to participate in our explorations of the unknown. Learn how the NOAA is dealing with low-latency live streaming in a post-Flash world, 以及如何将其流媒体传输到YouTube Live.

The era of black boxes and closed software is over; operating a streaming video service in 2019 requires a modular video workflow. 这不仅仅是将视频业务转移到云端, as services must optimize for the broadest coverage on the widest range of devices, 这意味着要使用最新的编解码器, packaging, and DRM technologies. Codec SDKs, microservices, docker容器现在是现代视频工作流的关键组成部分. Attendees hear what Microsoft and Beamr are doing to facilitate and accelerate modular video workflows that are ideally suited for video encoding, processing, 和包装功能，以促进任何视频服务的可扩展性.
