Aframe视频只能在ios上静音播放

我尝试在一个框架中播放360度视频,它在android和台式机上都能正常工作,但在ios上却无法正常工作。如果我将视频静音,则视频的开始有效,但是我需要声音。一些想法如何解决?这是我的代码:https://jsfiddle.net/237s96ka/1/

答案 0 :(得分:1)

Webkit policy仅允许自动播放无声视频。您需要像屏幕上的水龙头一样的用户手势才能播放有声视频。为了方便起见,从Webkit博客文章中进行复制:

  

关于用户手势要求的注释:当我们说某个动作必须“由于用户手势”而发生时,我们指的是导致对video.play()的调用的JavaScript,例如,必须直接来自处理触摸,点击,双击或按键事件的处理程序。因此,button.addEventListener('click',()=> {video.play();})将满足用户手势要求。 video.addEventListener('canplaythrough',()=> {video.play();})不会。

侦听器正常工作(触发“ it clicks_1”),但视频没有启动,并且出现以下错误: 未处理的承诺拒绝:NotAllowedError:在当前上下文中,用户代理或平台不允许该请求,这可能是因为用户拒绝了权限。 HTML:

<a-image id="playbutton_1" class="clickable" position="-5 0 0" width="2" height="2" rotation="0 -90 0" foo></a-image>

js:

  AFRAME.registerComponent("foo", {
    init: function() {
      var playthisvid_1 = document.querySelector('#playbutton_1');
      var videoEl_1 = document.querySelector('#intro');

  playthisvid_1.addEventListener('click', () => {

        videoEl_1.play();
        console.log("it clicks_1");
      })
    }
  })
