+我和许多 Linux 用户一样，使用的是台式机。相较于笔记本电脑，并没有预装摄像头和麦克风。 + +若要获得与现代智能手机相媲美的画质，你可能需要购买一款高端的网络摄像头。 + +在此教程中，我将逐步指导你如何将你的手机用作麦克风和摄像头，这将非常适用于在线会议场景。 + +### Ubuntu 下使用手机的摄像头和麦克风 + +> 🚧 本教程采用第三方网站 来托管音频和视频，因此，这并不是一项完全的开源方案。 + +我将指引你完成以下步骤： + + * 安装 OBS （如果你还未安装） + * 通过 `vdo.ninja` 生成邀请链接 + * 设置虚拟音频线缆（用于音频输出） + * 配置 OBS 以便从 `vdo.ninja` 重定向音视频流 + +首先，我们来看第一步。 + +> 📋 虽然本教程是在 Ubuntu 系统下完成的，但我相信，这些同样可以在其他 Linux 发行版上实现。你只需为你的发行版安装所需的包即可。你可以自行尝试，看看效果如何。 + +#### 1、在 Ubuntu 中安装 OBS + +OBS（Open Broadcaster Software）是众多用于录制和直播视频的优秀软件之一，许多直播者都选择使用 OBS 在各个数字化平台进行直播。 + +幸运的是，OBS 已经包含在 Ubuntu 的默认仓库中，你可以通过以下命令来安装： + +``` +sudo apt install obs-studio +``` + +#### 2、通过 VDO.ninja 生成直播邀请 + +在这一节，我将教你如何在 vdo.ninja 上生成一个直播邀请，进而从你的手机上开始直播音频和视频。 + +首先，访问 [VDO.ninja][1] 并点击 “创建可重用的邀请Create Reusable Invite”： + +![][2] + +接下来你会看到很多选项，包括质量设置，添加视频效果等。我推荐你使用默认设置，因为高质量视频需要更快的处理速度和更多的带宽。 + +为了创建一个链接，你只需要点击 “生成邀请链接GENERATE THE INVITE LINK” 按钮： + +![][3] + +完成后你会看到： + + * 你需要用你的手机扫描的二维码（当然，你也可以选择使用链接）。 + * OBS 的链接。 + +**稍后我会在本教程中继续介绍 OBS 配置，所以请暂时别关闭这个窗口。** + +首先，用你的手机扫描二维码，它会将你跳转到 VDO.ninja 的另一个页面，此时你需要： + + * 选择 “共享你的相机Share your Camera” 选项。 + * 在视频源中选择使用前置或后置摄像头（默认为前置）。 + * 点击 “开始Start” 按钮后，它将开始在 OBS 连接的页面上进行直播。 + +![][4] + +#### 3、在 Ubuntu 上为 OBS 配置虚拟线缆 + +> 🚧 这种设置方法仅适用于 PulseAudio，并且在重启系统后虚拟线缆将被撤销。 + +首先，我们来解释一下“虚拟线缆virtual cable”的概念，以及为何我们需要它来将手机做为摄像头和麦克风使用。 + +虚拟线缆是一种用于将音频流从一个应用传输到另一个应用的软件。 + +然而遗憾的是，它只支持 Windows 和 macOS。 + +啥？！那我为什么还要介绍这个呢？ + +答案其实很简单。我找到了一种变通方法，你可以在**当前的会话**中获得与虚拟线缆类似的功能。 + +要设置虚拟线缆，首先需要使用以下命令加载 `module-null-sink` 模块： + +``` +pactl load-module module-null-sink sink_name=Source +``` + +然后，执行下面的命令创建一个名为 `VirtualMic` 的虚拟音源： + +``` +pactl load-module module-virtual-source source_name=VirtualMic master=Source.monitor +``` + +这两个命令将返回一些数字，但无需对其过多关注。 + +接下来，前往系统“设置Settings”，找到“声音Sound”部分的设置： + +![][5] + +然后进入 “输入Input” 部分，在此你会找到选择输入设备的选项。 + +将 “VirtualMic” 设为输入设备： + +![][6] + +这样就设置完了！ + +不过，如我之前所述，一旦你重启电脑，虚拟音频的设置就会被撤销，如果你打算经常使用手机作为摄像头和麦克风，这可能会造成一定的不便。 + +为了解决这个问题，你可以为这两个命令 [创建别名][7]，例如，为命令创建别名：`vc1` 和 `vc2`。 + +完成后，你就可以像这样 [一次执行两个命令][8]：`vc1 && vc2`。 + +#### 4、配置 OBS 从手机直播音视频 + +开始阶段，你需要打开我之前告诉你不要关闭的 VDO.ninja 标签页，并复制 OBS 链接： + +![][9] + +然后启动 OBS，在 “源Sources” 区域你会看到一个 “➕（加号）”按钮，点击这个按钮并选择 “浏览Browser”。 + +接着会弹出一个对话框，让你创建或选择一个源，你只需按下 “OK” 按钮即可： + +![][10] + +最后，将已经复制的链接粘贴进 “URL” 字段： + +![][11] + +然后你将能看到 OBS 正在使用你手机的摄像头： + +![][12] + +不过为了从你的手机接收音频，还有一些额外步骤需要执行。 + +首先，在菜单中点击 “文件File” 并选择 “设置Settings”： + +![][13] + +在出现的设置选项中选择 “音频Audio”，然后寻找到 “高级Advanced” 区域。 + +在 “高级” 区域里，你能找到 “监控设备Monitoring Device” 的选项，这里你需要选择 “Source Audio/Sink sink”： + +![][14] + +点击 “应用Apply” 保存更改。 + +对于大部分用户，此时音频应该已经能够正常工作了。如果你的音频依然无法工作，那么你可以按照以下步骤操作。 + +在 “音频混音器Audio Mixer” 区域，可能显示的是 “浏览Browser” 或 “桌面音频Desktop Audio”，也可能两者都显示。 + +点击 “桌面音频” 或 “浏览” 旁边的三个点（在我这个例子中，是 “桌面音频”），并选择 “高级音频属性Advanced Audio Properties”： + +![][15] + +然后，对于 “浏览” 和 “桌面音频”，都选择 “监控和输出Monitor and Output”： + +![][16] + +这样就可以了！现在你可以从你的手机上享受摄像头和麦克风的功能了。 + +#### 5、测试所有设置 + +为了测试这个设置，我在我们读书俱乐部的周会上用我的手机做为摄像头和麦克风，效果极佳。 + +![][17] + +你可以看到，上图显示摄像头和麦克风都在正常工作，这真的让我笑容满面 😸。 + +视频质量会取决于你的网络带宽，所以在开始重要的会议前，确保你有稳定的网络连接。 + +### 结语 + +作为一个没有摄像头和麦克风的台式计算机用户，我必须依靠笔记本或手机来参加工作会议，这让我感到非常烦躁。 + +需要注意的是，每次重启机器后，你都需要重新配置虚拟线缆，但这并不费时，因为只需要执行两条命令即可。 + +我已经多次使用这种解决方案，每一次都顺利运行。我真的希望你也能得到同样的结果。 + +*（题图：MJ/223b56b7-ffcc-4311-bfa6-8a25bfd5ad11）* + +-------------------------------------------------------------------------------- + +via:

Linux -====== - -Like many other Linux users, I use a desktop and unlike a laptop, you don't get a camera and mic pre-installed. - -And you have to invest in a premium webcam to match the quality of your modern smartphone. - -Well, in this tutorial, I will walk you through step-by-step how you can use your phone as a mic and camera which can be used in online meetings. - -### Use the phone's camera and mic in Ubuntu - -🚧 - -This tutorial utilizes a third-party website to host audio and video. Thus, it is not a completely open source solution. - -Here, I will guide you through the following: - - * Installation of OBS (if you haven't) - * Generate invite through `vdo.ninja` - * Setup virtual audio cable (for audio output) - * Configure OBS to redirect audio and video from `vdo.ninja` - - - -So let's start with the first one. - -📋 - -I have used Ubuntu in the tutorial. However, I believe that the same can be achieved on other distributions as well. You just have to install the needed packages for your distro and it should work. I let you experiment. - -#### 1\. Install OBS in Ubuntu - -OBS (Open Broadcaster Software) is one of the best software for recording and streaming videos and most streamers use OBS to live stream on digital platforms. - -The good thing is OBS is available in the default repository of Ubuntu and can be installed using the following command: - -``` - - sudo apt install obs-studio - -``` - -#### 2\. Generate an invite through VDO.ninja - -In this section, I will show you how you can generate an invite to stream your audio and video over vdo.ninja and how you can start streaming from your phone. - -First, go to [VDO.ninja][1] and click on `Create Reusable Invite`: - -![][2] - -It will show you multiple options such as quality settings, adding video effects, etc. I recommend using the default settings as you may need faster processing and more bandwidth for high-quality videos: - -And to create a link, all you have to do is click on `GENERATE THE INVITE LINK` button: - -![][3] - -And it will show you the following: - - * A QR code that you have to scan through your phone (alternatively, you can also use the link). - * Link for the OBS. - - - -**I will cover the OBS part later on this tutorial so please don't close the window.** - -First, scan the QR code from your smartphone and it will redirect you to another page of the VDO.ninja where you have to select the following: - - * Select `Share your Camera` option. - * You can choose a front or rear camera from the video source (the front will be selected by default). - * Hit the `Start` button and it will start the streaming on the OBS link. - - - -![][4] - -#### 3\. Setup a virtual cable for OBS on Ubuntu - -🚧 - -The method will only work with the PulseAudio and the virtual cable will be flushed out once you reboot. - -First, let's talk about what is virtual cable and why you need it to use your phone as a camera and mic. - -The virtual cable is software used for transfering audio streams from one application to another. - -But the sad part is that it is only available for Windows and macOS. - -Hmmmm???? So why am I writing this? - -The answer is simple. I found a workaround to this where you can have the same functionality as a virtual cable for **the current session**. - -To set up a virtual cable, first, you have to load the `module-null-sink` module using the following command: - -``` - - pactl load-module module-null-sink sink_name=Source - -``` - -And then, execute the given command to create a virtual audio source named `VirtualMic`: - -``` - - pactl load-module module-virtual-source source_name=VirtualMic master=Source.monitor - -``` - -Both commands will return some numbers that you don't have to worry about. - -Now, go to the system settings, and there you will find settings for sound: - -![][5] - -Next, go to the `Input` section and there, you will find the option to choose an input device. - -Chose `VirtualMic` as an input device: - -![][6] - -That's it! - -But as I said earlier, once you reboot the effect of virtual audio will be flushed and if you regularly want to use your phone as a camera and mic, it can be inconvenient. - -To cater to this, you can [create an alias][7] for those two commands. For example, you can create aliases for both commands: vc1 and vc2. - -Once done, you can [execute both commands at once][8] like this: `vc1 && vc2`. - -#### 4\. Setup OBS to stream audio and video from the phone - -First, open the VDO.ninja tab that I told you not to close and copy the OBS link: - -![][9] - -Once copied, open OBS, and under the `Sources` section, you will find a ➕ (plus) button. Click that button and select `Browser`. - -It will open a little prompt to create/select a source. Simply press the `OK` button: - -![][10] - -Finally, paste the link in the `URL` field: - -![][11] - -And soon, you will see OBS using your phone's camera: - -![][12] - -But there are a few extra steps to get audio from your phone. - -First, click on the `File` and choose `Settings`: - -![][13] - -There, Choose `Audio` and look for the `Advanced` section. - -In the Advanced section, you will find an option for `Monitoring Device` and there you have to choose `Souce Audio/Sink sink`: - -![][14] - -Apply the changes. - -For most users, the audio should be working by now. But if yours don't then here's how you can make it work. - -In the Audio Mixer section, it will be either the `Browser` or the `Desktop Audio` , or you may also see both of them. - -Click on those three dots for Desktop Audio or Browser (in my case, it's Desktop Audio) and choose `Advanced Audio Properties`: - -![][15] - -From there, choose `Monitor and Output` for the Browser and Desktop Audio: - -![][16] - -And that's it! You can enjoy the camera and mic from your phone. - -#### 5\. Test the whole setup - -To test this, I used my phone as a camera and mic in our book club's weekly meeting and it worked flawlessly. - -![][17] - -As you can see, the above image indicates a working mic and camera (which brought a smile to my face 😸). - -The video quality depends on the internet bandwidth so make sure you have a good connection before starting an important meeting. - -### Wrapping Up... - -I'm one of those desktop users who don't have access to a camera and mic and have to rely on a laptop or mobile for office meetings and I was irritated by that. - -Remember, you have to create a virtual cable every time you reboot, but it won't take much time as it takes two command executions. - -Have used this solution multiple times and it worked every time I put it to the test. I really hope you will have the same output. - --------------------------------------------------------------------------------- - -via: https://itsfoss.com/ubuntu-phone-camera-mic/ - -作者：[Sagar Sharma][a] -选题：[lujun9972][b] -译者：[译者ID](https://github.com/译者ID) -校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 - -[a]: https://itsfoss.com/author/sagar/ -[b]: https://github.com/lujun9972 -[1]: https://vdo.ninja/ -[2]: https://itsfoss.com/content/images/2023/08/Click-on-create-reusable-Invite-button.png -[3]: https://itsfoss.com/content/images/2023/08/Click-on-the-generate-invite-link-button.png -[4]: https://itsfoss.com/content/images/2023/08/setup-vdo.ninja-on-phone.png -[5]: https://itsfoss.com/content/images/2023/08/Open-sound-settings.png -[6]: https://itsfoss.com/content/images/2023/08/Choose-virtul-mic-as-an-audio-input-in-Linux-to-use-phone-s-camera-and-mic-.png -[7]: https://linuxhandbook.com/linux-alias-command/ -[8]: https://linuxhandbook.com/run-multiple-commands/ -[9]: https://itsfoss.com/content/images/2023/08/Copy-link-for-OBS.png -[10]: https://itsfoss.com/content/images/2023/08/Create-new-source-for-streaming-in-OBS-to-use-camera-and-mic-of-your-phone-in-Ubuntu-1.png -[11]: https://itsfoss.com/content/images/2023/08/Paste-VDO.ninja-link-in-OBS-to-use-your-phone-s-camera-and-mic-in-Ubuntu-Linux.png -[12]: https://itsfoss.com/content/images/2023/08/Stream-audio-and-video-from-your-phone-to-Ubuntu-Linux-using-OBS.png -[13]: https://itsfoss.com/content/images/2023/08/Open-settings-in-OBS.png -[14]: https://itsfoss.com/content/images/2023/08/Choose-virtual-audio-in-OBS-to-use-phone-s-mic-in-ubuntu-Linux.png -[15]: https://itsfoss.com/content/images/2023/08/Choose-advanced-option-to-use-audio-from-phone-in-Ubuntu-linux-using-OBS.png -[16]: https://itsfoss.com/content/images/2023/08/Enable-monitor-and-output-for-OBS.png -[17]: https://itsfoss.com/content/images/2023/08/Using-phone-s-camera-and-mic-in-Ubuntu-Linux.png
