小程序的video的按钮是白色的,当视频封面也是白色的时候会看不到播放按钮

这里我用的是Mpvue来写的,换成原生的话,道理其实一样的

代码如下:

<video
      id="myvideo"
      object-fit="fill"
      class="myvideo video-js vjs-fluid"
      :src="videoinfo.play_urls.mp4"
      :poster="videoinfo.cover_data.original"
      @play="playvideo"
      @pause="pausePlay"
      :show-center-play-btn="false"
      :enable-play-gesture="true"
      >
      <image v-show="playBtnShow" class="video_play_icon" @click="playvideo" src="xxx/default/advertisement/mdls_zjkp_bofang%402x.png"></image>
      </video>

data(){
	return {
		playBtnShow:true
	}
},
methods:{
	console.log('play')
      this.playBtnShow = false
      var videoplay = wx.createVideoContext('myvideo')
      videoplay.play()
},
pausePlay(){
      this.playBtnShow = true
    }




<style lang='less'>
.myvideo{
      height: 211px;
      width: 375px;
      .video_play_icon{
        position:absolute;
        left: 50%;
        top: 50%;
        transform: translate(-50%,-50%);
        width: 40px;
        height: 40px;
        z-index: 999
        }
    }
</style>
