uni-app APP video组件黑屏的？

<swiper class="swiper" :autoplay="autoplay" :circular="circular" :interval="interval" :duration="duration" @change="swiperChange">  
            <block v-for="(item, index) in urls" :key="index">  
                <swiper-item  @tap="previewImage(index)">  
                    <view v-if="item.type == 'video'" class="video-wrap">  
                        <video id="myVideo"  class="my-video"  :enable-progress-gesture="false" :controls="showControls"  :autoplay="false" :show-progress="true" :show-fullscreen-btn="showControls"  
                         :src="item.url" :show-center-play-btn="false" :show-play-btn="showControls" @play="showPlay = false" @ended="showPlay = true" @fullscreenchange="fullscreenchange"></video>  
                         <image v-if="showPlay" @tap.stop="play" src="/static/images/icon_play.png" class="icon-play"></image>  
                    </view>  
                    <custom-image v-else width="750rpx" height="750rpx" :src="item.url"></custom-image>  
                </swiper-item>  
            </block>  
        </swiper>
