HTML中视频展示方案 – 专业用户体验指南
解决方案思路
为了在HTML中优雅地展示上传视频并满足SEO要求,我设计了以下技术方案：
- 使用HTML5
<video>标签作为核心播放器 - 实现响应式设计确保移动设备兼容性
- 添加多种视频格式支持提升浏览器兼容性
- 提供清晰视频控制界面优化用户体验
- 添加结构化数据增强搜索引擎理解
- 提供相关资源链接提升E-A-T（专业性、权威性、可信度）
下面是符合百度算法和E-A-T原则的完整实现：

<h2>高级优化策略</h2>
<h3>1. 视频优化与压缩</h3>
<p>使用FFmpeg等工具优化视频文件：</p>
<div class="code-block">
<code>ffmpeg -i input.mp4 -vcodec h264 -acodec aac -crf 23 output.mp4</code>
</div>
<h3>2. 添加结构化数据</h3>
<p>通过Schema.org标记帮助搜索引擎理解视频内容：</p>
<div class="code-block">
<code><span class="tag"><script </span><span class="attr">type</span>=<span class="value">"application/ld+json"</span><span class="tag">></span></code>
<code>{</code>
<code> "<span class="attr">@context</span>": "<span class="value">https://schema.org</span>",</code>

<code> "<span class="attr">name</span>": "<span class="value">HTML视频嵌入指南</span>",</code>
<code> "<span class="attr">description</span>": "<span class="value">专业讲解HTML视频展示技术...</span>",</code>
<code> "<span class="attr">thumbnailUrl</span>": "<span class="value">https://example.com/thumbnail.jpg</span>",</code>
