【报Bug】使用video组件，内置浏览器报错：Uncaught (in promise)DOMException: The element has no supported sources.

示例代码：

<template>
<view>
<view class="page-body">
<view class="page-section">
<video id="myVideo" crossOrigin="anonymous" src="http://vjs.zencdn.net/v/oceans.mp4" @error="videoErrorCallback" :danmu-list="danmuList"
enable-danmu danmu-btn controls></video>

            <view class="uni-list">  
                <view class="uni-list-cell">  
                    <view>  
                        <view class="uni-label">弹幕内容</view>  
                    </view>  
                    <view class="uni-list-cell-db">  
                        <input @blur="bindInputBlur" class="uni-input" type="text" placeholder="在此处输入弹幕内容" />  
                    </view>  
                </view>  
            </view>  
            <view class="btn-area">  
                <button @tap="bindSendDanmu" class="page-body-button" formType="submit">发送弹幕</button>  
            </view>  
        </view>  
    </view>  
</view>  

</template>
<script>
export default {
data() {
return {
title: 'video',
src: 'http://vjs.zencdn.net/v/oceans.mp4',
inputValue: '',
danmuList: [{
text: '第 1s 出现的弹幕',
color: '#ff0000',
time: 1
},
{
text: '第 3s 出现的弹幕',
color: '#ff00ff',
time: 3
}
]
}
},
onLoad() {
this.videoContext = uni.createVideoContext('myVideo')
},
onReady: function (res) {
this.videoContext = uni.createVideoContext('myVideo')
},
methods: {
bindInputBlur: function (e) {
this.inputValue = e.target.value
},
bindButtonTap: function () {
var that = this
uni.chooseVideo({
sourceType: ['album', 'camera'],
maxDuration: 60,
camera: ['front', 'back'],
success: function (res) {
this.src = res.tempFilePath
}
})
},
bindSendDanmu: function () {
this.videoContext.sendDanmu({
text: this.inputValue,
color: this.getRandomColor()
})
},
videoErrorCallback: function (e) {
console.log('视频错误信息:')
console.log(e)
},
getRandomColor: function () {
const rgb = []
for (let i = 0; i < 3; ++i) {
let color = Math.floor(Math.random() * 256).toString(16)
color = color.length == 1 ? '0' + color : color
rgb.push(color)
}
return '#' + rgb.join('')
}
}
}
</script>

操作步骤：

<template>
<view>
<view class="page-body">
<view class="page-section">
<video id="myVideo" crossOrigin="anonymous" src="http://vjs.zencdn.net/v/oceans.mp4" @error="videoErrorCallback" :danmu-list="danmuList"
enable-danmu danmu-btn controls></video>

            <view class="uni-list">  
                <view class="uni-list-cell">  
                    <view>  
                        <view class="uni-label">弹幕内容</view>  
                    </view>  
                    <view class="uni-list-cell-db">  
                        <input @blur="bindInputBlur" class="uni-input" type="text" placeholder="在此处输入弹幕内容" />  
                    </view>  
                </view>  
            </view>  
            <view class="btn-area">  
                <button @tap="bindSendDanmu" class="page-body-button" formType="submit">发送弹幕</button>  
            </view>  
        </view>  
    </view>  
</view>  

</template>
<script>
export default {
data() {
return {
title: 'video',
src: 'http://vjs.zencdn.net/v/oceans.mp4',
inputValue: '',
danmuList: [{
text: '第 1s 出现的弹幕',
color: '#ff0000',
time: 1
},
{
text: '第 3s 出现的弹幕',
color: '#ff00ff',
time: 3
}
]
}
},
onLoad() {
this.videoContext = uni.createVideoContext('myVideo')
},
onReady: function (res) {
this.videoContext = uni.createVideoContext('myVideo')
},
methods: {
bindInputBlur: function (e) {
this.inputValue = e.target.value
},
bindButtonTap: function () {
var that = this
uni.chooseVideo({
sourceType: ['album', 'camera'],
maxDuration: 60,
camera: ['front', 'back'],
success: function (res) {
this.src = res.tempFilePath
}
})
},
bindSendDanmu: function () {
this.videoContext.sendDanmu({
text: this.inputValue,
color: this.getRandomColor()
})
},
videoErrorCallback: function (e) {
console.log('视频错误信息:')
console.log(e)
},
getRandomColor: function () {
const rgb = []
for (let i = 0; i < 3; ++i) {
let color = Math.floor(Math.random() * 256).toString(16)
color = color.length == 1 ? '0' + color : color
rgb.push(color)
}
return '#' + rgb.join('')
}
}
}
</script>

预期结果：

可以播放视频

实际结果：

Uncaught (in promise)DOMException: The element has no supported sources.
