什么是 WebM?

WebM 是一款为网络设计的开放、免专利税的媒体文件格式。

WebM 定义了文件容器结构、视频和音频格式。WebM 文件由 VP8 编码的视频流和 Vorbis 编码的音频流组成。WebM 文件结构是基于 Matroska 容器的。

WebM 的好处

  • 开放、创新。 A key factor in the web’s success is that its core technologies such as HTML, HTTP, and TCP/IP are open for anyone to implement and improve. With video being core to the web experience, a high-quality, open video format choice is needed. WebM 是 100% 免费/自由且依据 类 BSD 许可开源的。
  • 为网络优化。 Serving video on the web is different from traditional broadcast and offline mediums. Existing video formats were designed to serve the needs of these mediums and do it very well. WebM is focused on addressing the unique needs of serving video on the web.
    • Low computational footprint to enable playback on any device, including low-power netbooks, handhelds, tablets, etc.*
    • 简单的容器格式
    • 实时视频传输的最高质量
    • 即点即编码。Minimal codec profiles, sub-options; when possible, let the encoder make the tough choices.

* 注:此次初始开发预览发布的支持 WebM 的浏览器尚未完全优化,因此 have a higher computational footprint for screen rendering than we expect for the general releases. The computational efficiencies of WebM are more accurately measured today using the development tools in the VP8 SDKs. Optimizations of the browser implementations are forthcoming.
