小程序video置顶

page {
  overflow-y: none;
  height: 100vh;
}

.page__hd_media {
  position: fixed;
  width:100vw;
  top:;
  height: 30vh;
  z-index:;
  text-align: center;
}

video {
  width: 100vw;
  height: 100%;
}

.page__bd_media {
  box-sizing: border-box;
  height: 70vh;
  line-height:;
  position: fixed;
  bottom:;
}

<view class="page" >
  <view class="page__hd_media">
    <video src="{{video.videoUrl}}" bindplay="bindplay" bindtimeupdate="bindtimeupdate" bindpause="bindpause" bindended="bindended" id="{{video.id}}" initial-time="{{currentTime}}"></video>
  </view>
  <scroll-view class="page__bd_media" scroll-y>
    //页面内容
  </scroll-view>
</view>

直接在video标签 position: fixed;top: 0;   不好使video还是会随着页面滑动
