uniapp-视频video播放兼容问题-圆角实现

1.实现支付宝小程序-视频圆角，使用border-radius无法实现

真机测试无效

只能使用css在四个角覆盖上去了

    <div class="tips">
      <video
        id="myVideo"
        objectFit="cover"
        style="width: 100%"
        autoplay
        :show-fullscreen-btn="false"
        :show-play-btn="false"
        :controls="false"
        :show-center-play-btn="false"
        :show-loading="false"
        :show-mute-btn="false"
        muted
        loop
        src="https://XXX.mp4"
        poster="@/static/image/XXX.jpg"
      ></video>
      <div class="box_right_top"></div>
      <div class="box_right_bottom"></div>
      <div class="box_left_top"></div>
      <div class="box_left_bottom"></div>
