【报Bug】video 高码率 800M MP4视频播放卡顿，图像停止，声音继续播放

示例代码：

<template> <view class="area"> <video v-if="refId != ''" ref="video_${refId}" id="video_${refId}" src="src" @play="play"
@pause="pause"
@waiting="waiting"
@timeupdate="Timeupdate" loop="true" enable-progress-gesture="false" page-gesture="false" initial-time="startTime" controls="false" show-fullscreen-btn="false" show-center-play-btn="false" class="video" style="boxStyle" @ended="endedPlay" objectFit="system=='ios'?'fill':'cover'" ></video>
<progress :percent="progress" stroke-width="2" activeColor="rgba(255,255,255,0.8)"
backgroundColor="rgba(255,255,255,0.3)" class="progress"/>
</view>
</template>
<script>
export default {
watch: {
state(newValue,oldValue){
var videoCtx = this.$refs[video_${this.refId}];
switch (newValue) {
case 'play':
videoCtx.play();
break;
case 'continue':
videoCtx.play();
break;
case 'pause':
videoCtx.pause();
break;
case 'stop':
videoCtx.pause();
break;
default:
break;
}
}
},
props: {
startTime:{type:Number,default:0},
system:{type:String,default:''},
idx:{type:Number,default:0},
state: {type: String,default:'stop'},
src: {type: String, default() { return '';}},
boxStyle: {type: Object, default() {return {};}},
refId: {type: String,default() { return '';}},
progress:{type:Number,default:0}
},
methods: {
Timeupdate(e){
this.$emit('timeupdateEvent', e,this.idx);
},
endedPlay(e) {
this.$emit('endedEvent', e,this.idx);
},
play(e){
this.$emit('playEvent', e,this.idx);
},
waiting(e){
this.$emit('waitEvent', e,this.idx);
},
pause(e){
this.$emit('pauseEvent', e);
}
}
};
</script>

<style scoped>
.area {position:relative;flex: 1;background-color: #0A98D5;}
.video {width: 750rpx;flex: 1;}
.progress{position:absolute;bottom:0rpx;left:0px;width: 750rpx;z-index:4;flex: 1;}
</style>

操作步骤：

把以上代码作为视频播放组件
<list>
<cell>
引入组件
</cell>
</list>
直接使用video 组件，src 设置远高码率的 远程视频地址

预期结果：

希望能够流畅播放,不卡顿

实际结果：

图像卡顿
