I won't use a physical webcam! Tell me alternatives so I can use an emulated device!?

✅ YES. You can use media files instead of a webcam, or use the camera/media injection widget with custom media. With Genymotion Desktop, you can also use your host machine webcam if needed, but for no physical webcam the supported alternative is image, video, or audio injection.

Details:

• In the Camera and Media Injection widget, you can select Custom media and drag-and-drop a video or image file, or browse for one.
• You can also use an audio file as microphone input.
• The camera can display a selected video or image file, and a video file will play in the device camera.
• This feature is for Genymotion Desktop and is not available with Genymotion PaaS right now.

If your goal is testing, demo, or automation in the cloud, Genymotion SaaS also offers emulated features and demo sessions. Source: Genymotion Android Emulator in the Cloud

What are you trying to emulate in the app camera, a live feed, or a prerecorded scene?
