    <button @click="changevideourl(0)">更换视频地址 - 录屏</button>
    <button @click="changevideourl2(1)">更换视频地址 - 直播流</button>
    <button @click="delvideourl(src.length - 1)">删除视频</button>
    <div class="video-div">
      <video
        v-for="item in src"
        :id="'video_' + item.id"
        class="video video-js vjs-default-skin"
        preload="auto"
        :key="item.id"
      >
        <source :src="item.src" :type="item.type" />
      </video>
    </div>
