The app invokes camera and keeps the image as preview for streaming usage
* This app is meaningless unless streaming use.
Usage:
1.Stream the phone's screen with Chromecast, etc.
2.Run the Preview app. The app keeps camera's preview. You can place the phone at any place so that it works as a remote camera.
- Fling (flick) can change front / back camera
- Pinch can zoom the center of screen
- Touching the screen pauses the preview, allowing you to zoom in/out on the still image. Touching it again resumes the preview
Typical camera-apps have annoying menus and buttons on screen, and can be shutdown involuntarily at a fixed period of time. This app keeps previewing camera as long as battery lasts.
