RSC-010, ERROR, [Reference to non-standard resource type found.]

使用epubcheck检查epub文件,报错：

<message>RSC-010, ERROR, [Reference to non-standard resource type found.], chapter-001.xhtml (1087-112)</message>

<message>RSC-011, ERROR, [Found a reference to a resource that is not a spine item.], chapter-001.xhtml (1087-112)</message>

源文件：

<div class="imagediv3">
<a class="image4" style="width:50px;height:50px;z-index:1;" href="./Media/chapter-001hyperlinkitem1.mp4"/>
<img class="image4" src="Media/chapter-001image1.jpeg" id="imageItem-4" alt="Media/chapter-001image1.jpeg"/>
</div>

解决：
<div class="imagediv3">
<video src="./Media/chapter-001hyperlinkitem1.mp4" id="videoID_1">Your browser does not support the video element.</video>
<a class="image4" style="z-index:1;" href="javascript:document.getElementById('videoID_1').play();"/>
<img class="image4" src="Media/chapter-001image1.jpeg" id="imageItem-4" alt="Media/chapter-001image1.jpeg"/>
</div>

只消除了报错信息，暂时无法实现点击图片播放视频
