HTML5 video tag in chrome - wmv
提问by elcuco
I need to make a page which displays a video. Firefox and and Opera support the OGG format, no problem there. Chrome is ... "stupid" and does not recognize OGG.
我需要制作一个显示视频的页面。Firefox 和 Opera 支持 OGG 格式，没问题。Chrome 是……“愚蠢的”，无法识别 OGG。
Does Chrome on Windows know how to handle WMV? I already have them encoded, and no I cannot recode new videos since the media is limited in spaced (CDROM).
Windows 上的 Chrome 是否知道如何处理 WMV？我已经对它们进行了编码，不，我无法重新编码新视频，因为媒体的空间有限（CDROM）。
My code currently looks like this (and not working in chrome)
我的代码目前看起来像这样（并且不适用于 Chrome）
<video controls>
<source codecs="theora, vorbis" media="video/ogg" src="video.ogv" />
<source media="video/x-ms-wmv" src="video.wmv" />
Please install a new browser, or just get out
</video>
Note that I am missing a codec entry, does anyone know what I need to put there?
请注意，我缺少一个编解码器条目，有人知道我需要在那里放什么吗？

To the best of my knowledge, Chrome doesn't support WMV. Opera, Firefox and Chrome support Ogg Theora+Vorbis, while Chrome and Safari support MPEG-4 H.264+AAC.
据我所知，Chrome 不支持 WMV。Opera、Firefox 和 Chrome 支持 Ogg Theora+Vorbis，而 Chrome 和 Safari 支持 MPEG-4 H.264+AAC。
Your markup needs a bit of fixing. There is no codecs attribute, use the type attribute instead. Also, you usually don't need the media attribute at all. Here's your cleaned up markup:
您的标记需要一些修复。没有 codecs 属性，请改用 type 属性。此外，您通常根本不需要 media 属性。这是您清理的标记：
<video controls>
<source type="video/ogg; codecs=theora,vorbis" src="video.ogv">
<source src="video.wmv">
Your browser doesn't support video, you may download the
video instead: <a href="video.ogv">Ogg</a>
</video>
The only browser that might be able to play WMV is Opera on Linux (if you happen to have the right GStreamer plugins installed). That's not very useful, so you should probably just not use WMV with <video> at all.
唯一能够播放 WMV 的浏览器是 Linux 上的 Opera（如果您碰巧安装了正确的 GStreamer 插件）。这不是很有用，因此您可能根本不应该将 WMV 与 <video> 一起使用。

Chrome handles wmv with a plugin, but not with a codec in HTML5. Chrome and HTML5 handles H.264.
Chrome 使用插件处理 wmv，但不使用 HTML5 中的编解码器。Chrome 和 HTML5 处理 H.264。
