<li><del>摄像头推流到web页面</del> √</li>
<li><del>降低画面延时</del> <del>3s不能再少了。。</del> 菜鸡，没那个能力。</li>
<li><del>页面鉴权？？</del> 懒得要死鉴个鸡毛</li>
<li><del>加上音频采集</del> 不加了，又要买usb麦</li>
<li><del>造个小车</del> √</li>
<li><del>树莓派GPIO控制小车马达转动</del> √</li>
<li><del>实现web控制</del> √ 还行还行</li>
</ol>
<p>注：因页面有几秒延时(内网3s，外网7s左右)，前进后退动作只持续0.3s<p>
