谷歌 Outlines Crucial HTML5 Video Development During Keynote
In an opening day keynote to the 流媒体 East conference in New York City, 马特·弗罗斯特, senior business product manager for 谷歌Chrome, guided the audience through the past and the possible future of online video.
"Video at 谷歌 started as an experiment,弗罗斯特说, noting how a single fulltime 谷歌 employee worked on video in 2004, along with a few others giving 20 percent of their time. Only two years later, 谷歌 was a video giant when it acquired YouTube.
"There is no single standard for video on the web,弗罗斯特说, explaining the challenges for online content distributors. While a single format would be beneficial, there currently isn't one that works well with all devices, 他说.
What's needed is a solution that lets content owners encode once for all destinations. YouTube is popular even with enterprises, 弗罗斯特说, because it removes the burden of formats, handling all transcoding in the background.
谷歌's approach to HTML5 solves many of the problems facing content owners today, 弗罗斯特断言, explaining how the Chrome team is devoted not only to making sure HTML5 video works well in Chrome, 但在其他浏览器中也是如此. Its goal is to improve HTML5 video so that it can fulfill the same role that only Flash plays today.
Frost listed key areas where HTML5 needs improving: content protection, 自适应流媒体, 和字幕. The first two are especially important to premium content owners, 他说, and 谷歌 is making progress on all three.
内容保护, 谷歌, 微软, and Netflix recently made a proposal to W3C suggesting encrypted media extensions in HTML5. The proposed solution could be achieved with only a minor change to the HTML5 spec, 弗罗斯特说. "It is a very promising initiative that should result in content protection appearing in HTML5 browsers soon,他补充道.
对于自适应流, 谷歌 has evaluated all the possible formats and has thrown its weight behind MPEG DASH, 弗罗斯特说. 谷歌 has published a media source extension proposal at W3C.
Looking at the work that remains to be done with HTML5 video, 弗罗斯特说 that native browser support for video and audio isn't enough; the core technologies must be modern and keep pace with the web. The goal isn't just media playback, but turning the browser into an application platform and social platform. The developer community can't build cutting-edge experiences with ten-year-old technology, he added.
Today's viewers put up with current online video playback because they remember the "bad old days" of postage stamp-sized video and proprietary streams, 弗罗斯特说, but there's much yet to be done.
"Web video can be so much better," 弗罗斯特说.
Frost finished by detailing four key areas of investment for web video: authoring (the ability to easily and quickly encode once for all devices), distribution (flexible for any user's environment, 有盈利选择), playback (fast access with low power consumption), and innovation (an eye to future compatibility).
