如何将虚拟相机发送到Ubuntu中的Genymotion或Android Studio Emulator? [英] How can I send a virtual camera to Genymotion or Android Studio Emulator in Ubuntu?
问题描述
我使用v4l2loopback和ffmpeg创建了一个虚拟相机.我用于ffmpeg的命令是:ffmpeg -re -l oop 1 -i vin.png -vf format = yuv420p -f v4l2/dev/video2
I created a virtual camera using v4l2loopback and ffmpeg. The command I use for ffmpeg is: ffmpeg -re -l oop 1 -i vin.png -vf format=yuv420p -f v4l2 /dev/video2
vin.png是我要流式传输到网络摄像头的图像，/dev/video2是我使用v4l2loopback创建的虚拟网络摄像头.虚拟网路摄影机可以运作，例如与 onlinemicetest.com/webcam-test .我在Ubuntu 20.40上将Genymotion模拟器与最新的Android API(我尝试过7.0、8.1和10.0)一起使用.Genymotion检测到虚拟相机，但仅显示虚拟图像: Genymotion的虚假图片错误我也尝试过(并且更愿意使用)android studio模拟器.但是我只能在设备摄像头的配置中选择Webcam0，它指向的是真正的集成摄像头，而不是我的虚拟摄像头.
vin.png is the image I want to stream to the webcam and /dev/video2 is the virtual webcam I created with v4l2loopback. The virtual webcam works and I can see it e.g. with onlinemicetest.com/webcam-test. I'm using the Genymotion emulator with the newest Android API (I tried 7.0, 8.1 and 10.0) on Ubuntu 20.40. Genymotion detects the virtual camera but only displays a dummy image: Wrong dummy Image from Genymotion I also tried (and would prefer to use) the android studio emulator. But I can only select Webcam0 in the configuration of the device camera and that points to the real integrated camera and not to my virtual webcam.
我不需要使用ffmpeg，但是我确实需要使用一个工具，该工具可以让我控制要从命令行流式传输的图像.
I don't need to use ffmpeg, but I do need to use a tool that lets me control which image to stream from the command line.
有没有办法解决这个问题?提前非常感谢！
Is there a way to solve this? Many thanks in advance!
2020年11月17日更新:Genymotion支持人员回答我，他们计划将来支持虚拟相机.他们可能已准备在2021年中添加此功能.
Update 17.11.2020: The Genymotion support answered me, that they plan to support virtual cameras in the future. They might be ready to add this in mid 2021.
推荐答案
使用OBS和Android模拟器的解决方案:
Solution using OBS and Android Emulator:
- 遵循本教程: https://blog.jbrains.ca/permalink/using-obs-studio-as-a-virtual-cam-on-linux
- 使用以下命令更改您的obs场景: https://gist.github.com/nooitaf/9aabf72d00e16a61ea301c69ff38d804
- 检查您正在使用哪个/dev/video:v4l2-ctl --list-devices
- 在您的avd中检查哪个摄像头链接到了该视频:./emulator -avd Pixel2 -webcam-list
- 使用该摄像头从命令行启动模拟器:./emulator -avd Pixel2 -camera-back webcam2
