我想在没有任何用户手势的情况下使视频自动播放.我知道，根据最近的Google和Apple网络视频政策，我们不能在没有用户手势的情况下自动播放具有音频的视频.但是，我看到的网站仍然可以在现代网络浏览器中自动播放视频.

I want to make the video autoplay without any user gesture in reactjs. I know as per recent google and apple web video policy we cannot autoplay a video having audio without user gesture.But i have seen few websites which still autoplays the video across modern web browsers also.

我在stackoverflow上遇到了许多与此问题相关的问题，但没有一个帮助我.

I came across many questions related to this issue on stackoverflow but none helped me.

这是我尝试过的.

尝试1.

<video id="miniVideo" preLoad="yes" autoPlay="autoplay" loop width="100%" height="auto" playsInline> <source src="/mini/video/cooper.mp4" type="video/mp4" /> <source src="/mini/video/cooper.webm" type="video/webm" /> </video>

尝试2.

<iframe playsInline id="miniVideo" src="/mini/video/cooper.mp4" width="100%" height="400px" allow="autoplay; fullscreen"></iframe>

尝试3.

脚本:

componentDidMount(){ var videoTimer = document.getElementById("miniVideo"); videoTimer.play(); }

HTML:

<video id="miniVideo" width="100%" height="100%"> <source src="/video/cooper.mp4" type="video/mp4" /> <p>This browser does not support the video element.</p> </video>

我们将非常感谢您的帮助.谢谢

推荐答案

我不确定Safari，但Chrome更改了自动播放政策.在这里查看: developers.google/web /updates/2017/09/autoplay-policy-changes

I am not sure about Safari but Chrome has changed the autoplay policy. Look here:developers.google/web/updates/2017/09/autoplay-policy-changes

为了自动播放，请添加归属于video标签的muted. 例如:

In order to autoplay, add muted attributed to video tag. For example:

import React, { Component } from 'react'; class Player extends Component { constructor(props) { super(props); this.state = { isVideoMuted: true }; } handleMuteState = () => { this.setState(prevState => ({ isVideoMuted: !prevState.isVideoMuted })); } render() { return ( <div> <video muted={this.state.isVideoMuted} src="./video.mp4" /> <button onClick={this.handleMuteState}>{this.state.isVideoMuted ? 'Unmute' : 'Mute'}</button > </div> ); } } export default Player;
