three.js带WebRTC问题的位置音频设置MediaStreamSource（听不到任何声音）

大家好！我在discord上问了这个问题，但没有得到回应。我在下面添加了更多信息，希望能帮助澄清我的问题。我有一个传入的WebRTC音频/视频流，我正在将其拆分为视频流用作纹理，还有一个音频流，我正在尝试将其用作定位音频的源对象。我正在使用positionAudio.setMediaStreamSource功能3和r115版本。运行以下代码后，我在场景中获得一个音频对象（即，如果我打印出来场景.儿童，我看到下面有一个MediaStreamSourceNode的对象AudioObj.context.source). 但是，我什么也没听到。任何关于如何调试的建议都将是超级> 相关问题：如何使用AudioLoader在音频中传输音频？问题仅供参考：下一版本R109，三、音频提供一个新方法。setMediaStreamSource（）用于将Web RTC媒体流包括到Web音频管道中。可能对您有用stackoverflow.com带有WebRTC流的ThreeJS位置音频不会产生声音22three.js问byRmRon UTC时间18日上午9:10-6月22日由lukasIO在post#34中解决，我发现我和@cat在这里做错了什么…而不是this.positionAudio.setMediaElementSource(这是音频元素)；我们需要使用this.positionAudio.setMediaStreamSource(this.audioElement.srcObject)为了让它在chrome中工作…猫：但是，我什么也没听到。你能不能先用THREE.Audio而不是THREE.PositionalAudio试试？只是为了确保没有转换问题。好的，确认了这对>/pre> 不起作用（没有声音），有趣的是， 1. 这对来自Navigator.GetUserMedia() 2. 的本地音频流起作用。当我将相同的音频流导入一个元素时，我可以听到>/pre>有什么想法吗？能否将代码作为git存储库共享？或者作为一个可编辑的实时示例？当然可以，那辆车相关代码在public/js/index.js: 260（我刚刚很快适应了在没有我的WebRTC ICE服务器提供商（Twilio）的情况下工作，所以如果有任何东西不工作，请告诉我，我会看一看）GitHubAidanNelson/YORB2020 10YORB2020是一个共享的在线空间，可以闲逛、协作和工作。-艾登尼尔森/约尔B2020谢谢！下载repo并安装依赖项后，我在使用

Please check out the link in my previous post. cat:Or is there more I can do to debug on my end?Unfortunately no, this is a browser bug.I meant an issue on the three.js repo, just so it is visible to the three.js community? Let me know.Thanks again for the help! That was a persnickety little bug.I think the discussion in this topic is sufficient. Especially since we can\"t fix this issue on our side.Hi @Mugen87, just wanted to follow up on this thread as it seems the Chromium bug thread 7 has now referenced this thread.A user there has mention a possible solution:Create an HTML5 audio element,Set the audio element source to the incoming MediaStream,Use that audio element as a source for the webAudio positional audio object.I am trying to implement this, but am running into the issue of both audio sources (the HTML5 audio element and the WebAudio / three.js positionalAudio) now playing (and therefore losing the the stereo imaging / positional-ity of the positionalAudio).Do you have any recommendations for this? cat:A user there has mention a possible solution:That user was me . cat:Do you have any recommendations for this?Um, that does not sound right to me. I\"ve tested this workaround successfully on my computer Mugen87:Um, that does not sound right to me. I\"ve tested this workaround successfully on my computer Ahh, wonderful!Well, maybe you could tell me what I was doing wrong here?I am using Mediasoup 3 as a selective forwarding unit server, so consumer指传入的媒体源。*// Create HTML audio = consumer;// THREE.js> cat:These two lines should not be necessary.I was mainly using those two lines to test different scenarios.Here is my current issue:When the HTML audio element is playing:In Firefox (75.0), I can set the HTML audio element volume to 0 and can still hear the positionalAudio.In Chrome, when I set the HTML audio element volume to 0, I cannot hear positionalAudio.To be clear, it is unclear whether I am hearing positionalAudio when the HTML audio volume is active over the sound of the global audio. When the HTML audio is not playing:In Firefox and Chrome, I don\"t hear the PositionalAudio object.Could you share your workaround test code?I\"m wondering if I am missing something simple…This example uses an HTML5 audio element and passes it to an instance of PositionalAudio.https://threejs.org/examples/webaudio\\u35唯一的区别是音频元素的创建方式。虽然这不重要 3. Create an HTML5 audio element, 4. Set the audio element source to the incoming MediaStream, 5. Use that audio element as a source for the webAudio positional audio object. 6. In Firefox (75.0), I can set the HTML audio element volume to 0 and can still hear the positionalAudio. 7. In Chrome, when I set the HTML audio element volume to 0, I cannot hear positionalAudio.To be clear, it is unclear whether I am hearing positionalAudio when the HTML audio volume is active over the sound of the global audio. 8. In Firefox and Chrome, I don\"t hear the PositionalAudio object.
