HTML5视频广告代码支持哪些编解码器？

What codecs will be supported with the HTML5 video tag?

Will it vary by browser, or is there a spec of specific codec that will be supported?

推荐答案

根据维基百科：

当前的HTML5草案规范
未指定浏览器应在视频
标记中支持哪些视频格式
。用户代理可以免费支持
任何他们认为合适的视频格式。

The current HTML5 draft specification does not specify which video formats browsers should support in the video tag. User agents are free to support any video formats they feel are appropriate.

HTML5是草稿格式虽然这可能会改变。

HTML5 is in draft format though and this may change.

关于各种算法的适用性一直存在争议，似乎目前并非所有参与者都能就答案达成一致。三个主要竞争者是Ogg / Theora，H.264和VP8 / WebM。各种实现的当前状态因浏览器而异。

There is an ongoing debate about the suitability of various algorithms and it seems that currently not everyone involved is able to agree on an answer. The three major contenders are Ogg/Theora, H.264 and VP8/WebM. The present state of the various implementations varies between the browsers.

当前的HTML5草案规范指出：

The current HTML5 draft spec states:

更新信息后更新。

It would be helpful for interoperability if all browsers could support the same codecs. However, there are no known codecs that satisfy all the current players: we need a codec that is known to not require per-unit or per-distributor licensing, that is compatible with the open source development model, that is of sufficient quality as to be usable, and that is not an additional submarine patent risk for large companies. This is an ongoing issue and this section will be updated once more information is available.
