Hardware codecs in FFmpeg like those from Intel and NVIDIA deliver significant performance gains over x264/x265, 但是以质量较低而闻名，并且使用完全不同的命令集. This session benchmarks the performance and quality of these codecs and detail the FFmpeg command syntax. 与会者将学习何时以及如何在您的视频点播和实时编码工作流程中使用这些硬件编解码器.

CMAF is a format that can create one set of media files deliverable via DASH and HLS (and other ABR formats), 可能节省大量的编码费用, packaging, storage, and delivery. Decoupling manifests from the media segment formats and being able to deliver the same media segments anywhere is a huge win. 随着DRM加密需求的增加, CMAF offers the best path forward for reach and capability while reducing the formats and versions necessary to hit every platform. 与会者离开时了解了CMAF的优缺点，并获得了部署CMAF的高级路线图.

机器学习即服务(MLaaS), 人工智能的一个子集, 在过去的几年里取得了很大的进步吗. Now is the time to really make MLaaS work for you and enhance your media discoverability and insights. 这些增强包括视频可搜索性和可发现性, 自动生成文本和翻译, or even pinpointing specific faces or people within your live surveillance streams in an efficient manner. The key to harnessing this power is to learn to determine your needs and code against the numerous ML service APIs that are out there to make them work for you. Attendees walk away with an understanding of how to harness the power of AI machine learning to increase the ROI of their video libraries and build some compelling and innovative intelligence from their libraries of dark media data.

The next great codec battle will be between the Alliance Open Media’s AV1 codec and MPEG’s Versatile Video Coding (VVC) technology. In this talk, Bitmovin codec engineer Christian Feldman discusses the coding tools and performance of both codecs, and the lessons that he’s learned implementing AV1 in Bitmovin’s encoding stack for cloud and on-premise deployment. 在这45分钟的技术潜水中了解这两种编解码器的优缺点.

Companies on the cutting edge of video engineering and development share the latest technologies that are pushing the industry forward.

When news is breaking, broadcasters need fast, 将他们的内容从现场带到生产现场的点播方式, 甚至来自世界各地意想不到的地方. 通过利用SRT协议在全球微软Azure光纤网络上传递媒体, the SRTHub helps broadcasters and video service providers easily build live and file-based content routing workflows on-demand, with security and reliability.

For streaming providers delivering content over multiple infrastructures to multiple makes and models of consumer devices and pay-TV set-top boxes, optimizing customer satisfaction requires advanced QoE metrics that encompass every step of the video delivery chain. These include accurate monitoring to maximize performance of large-scale video distribution networks, 以及有效的问题识别, localization and resolution. 传统的方法在视频传输链上的不同点独立运行, reporting partial, 不一致和碎片化的测量. This session will discuss how unified end-to-end quality monitoring—instantaneous and correlated measurement at every stage of delivery—is fundamental to understanding the final effect on the viewer’s quality-of-experience.

The Twitch video team has been working on adding multiple codec capabilities to Twitch’s video streaming platform, VP9是除H之外第一个加入的编解码器.264. As other codecs such as AV1, HEVC, VVC, 和MPEG5都显示出很好的压缩效率, we aim to be ready when the time comes to add any of these technologies and deliver better video quality at much lower bitrates. This presentation will cover the process it took Twitch engineers to change the platform from a single codec to multiple codecs. A wide range of technical topics will be covered, from codec choice to player support and validation

开发一个视频播放器不是一件容易的事. Many different technologies and specifications must come together to create an accessible and cohesive experience. 当你是一个小团队时，这可能会让你感到不知所措, 特别是当玩家需要自定义功能时. 在这次演讲中，我们将通过快速获得核心视频体验并运行. Then we dive into making our player unique and adding additional functionality such as closed captions and HLS streaming. 所有使用的库都是开源的，包括React, Video.js, vtt.js, and hls.js.

对于许多在线视频部署来说，分析的细节和范围可能是令人望而生畏的. 在本课程中，学习如何从您的网络直播中收集关键的受众参与数据. 对开放源代码和商业服务进行了探索和演示.

HLS和MPEG-DASH是目前基于http的流媒体直播的标准, 但是这些设计本身就很慢，并且会增加实时馈送的延迟. 亚秒级延迟对于赌博等场景至关重要, auctions, interactive communications, VR, sports, and gaming. WebRTC is touted for its sub-second latency but couldn’t scale to the volume needed by CDNs and couldn’t reach Apple devices. In this session, learn about a novel WebRTC-based solution that would match current CDNs in terms of reach (all devices), quality, cost, and scale, 同时提供低于500毫秒的延迟.
