HTML5视频验证错误 [英] HTML5 Video Validation Error

问题描述

我有以下标记，使用 VideoJS 播放器实现（我也可以包含js，如果它成为必要）：

I have the following markup, implemented using the VideoJS player (I can include the js too, if it becomes necessary):

<video id="example_video_1" class="video-js" width="736" height="352" controls="controls" autoplay="autoplay" loop="loop"> 
    <source src="a/v/jt_homevid.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'>                         
    <source src="a/v/jt_homevid.ogg" type='video/ogg; codecs="theora, vorbis"'>         
    <object id="flash_fallback_1" class="vjs-flash-fallback" width="736" height="352" type="application/x-shockwave-flash"  data="http://releases.flowplayer.org/swf/flowplayer-3.2.1.swf"> 
        <param name="movie" value="http://releases.flowplayer.org/swf/flowplayer-3.2.1.swf" /> 
        <param name="allowfullscreen" value="true" /> 
        <param name="flashvars" value='config={"playlist":["<? echo $currurl; ?>/a/v/slide-1-joshtaerk-cdcover.jpg", {"url": "<? echo $currurl; ?>/a/v/jt_homevid.mp4","autoPlay":false,"autoBuffering":true}]}' />         
        <img src="a/v/slide-1-joshtaerk-cdcover.jpg" width="736" height="352" alt="Poster Image" title="No video playback capabilities." /> 
    </object> 
</video> 

目前这是HTML验证失败，并出现以下错误消息：

And this is currently failing HTML validation, with the following error message:

第152行，第82列：在此上下文中，元素源不允许作为元素视频的子元素。 （抑制此子树中的其他错误。）...

可以使用元素源的上下文：作为媒体元素的子元素，在任何流内容或轨道元素之前。元素视频的内容模型：如果element有一个src属性：零个或多个轨道元素，然后是透明的，但是没有媒体元素后代。如果元素没有src属性：零个或多个源元素，那么零个或多个轨道元素，则透明，但是没有媒体元素的后代。

Line 152, Column 82: Element source not allowed as child of element video in this context. (Suppressing further errors from this subtree.)…
Contexts in which element source may be used:As a child of a media element, before any flow content or track elements.Content model for element video:If the element has a src attribute: zero or more track elements, then transparent, but with no media element descendants.If the element does not have a src attribute: zero or more source elements, then zero or more track elements, then transparent, but with no media element descendants.

我明白我可能不应该相信W3C HTML5验证器在它的开发过程中，但是如果我错误编码，我想确定将来在哪里以及如何防止它。此外，我想确定我正确地解释了错误消息，我认为这应该发生在路上。

I do understand that I maybe should not be trusting the W3C HTML5 validator at this point in it's development, but if I have miscoded, I would like to identify where, and how to prevent it in the future. Also, I'd like to be sure I am interpreting the error message correctly, which I think should happen along the way.

我看不出我是如何偏离的允许此元素的上下文。它是媒体元素的子元素（特别是< video> 标记），它在我认为的任何流内容之前，因为我找不到< source> 元素在W3C上列为流内容（在此链接），我目前没有任何< track> 元素。

I cannot see how I have deviated from the allowed contexts for this element. It is a child of a media element (Specifically the <video> tag), it is before any 'flow content' I believe, because I cannot find the <source> element listed as flow content on the W3C (at this link), and I do not have any <track> elements currently.

我不确定的一件事是< video> 元素的内容模型中'then transparent'的定义。根据我的理解，如果媒体元素内的元素在媒体元素的父元素内也是有效的（来自这个帖子：我可以在HTML5< audio>元素中有多个src属性吗？或者src属性和< ;来源>元素？），这可能是我错过的地方，因为我在< video> 元素>< div> 父？

One thing I'm not certain about is the definition of 'then transparent' in the content model for the <video> element. From my understanding is that if elements inside the media elements are valid if they are also valid inside the parent of the media element (from this thread: Can I have multiple src attributes in an HTML5 <audio> element? Or an src attribute and a <source> element?), and this is perhaps where I've misstepped, as I have the <video> element inside a <div> parent?

任何人都可以确认这是我的错误，或者我是否应该忽略验证消息？如果这是一个错误，我还应该如何布置我的内容？通过直接设置视频元素的样式？

Can anyone confirm this as my mistake, or whether I should ignore the validation message? If this is a mistake, how else should I be laying out my content? By styling the video element directly?

提前致谢。

推荐答案

您的理解是正确的，这看起来像验证器错误。

Your understanding is correct, and this does look like a validator bug.

Validator.nu ，它基于相同的验证器引擎作为W3C验证器，但可能是更高版本，通过标记没有任何错误。

Validator.nu, which is based on the same validator engine as the W3C validator, but is likely to be a later version, passes the mark-up without any errors.
