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
