📖 How to use

Import the downloaded "RealCamera0.0.0.json" file into your project.

🎞️ About AlternativeVideo files

The RealCamera object requires a temporary video file. The RealCamera object attempts to launch the camera at the same resolution as the video. If the camera does not support that resolution, it will fail to launch.

I have prepared video files of common resolutions for your use.

• 640 x 480: resolution supported by most cameras
• 1280 x 720: higher resolution with 16:9 ratio
• 480 x 640: For smartphones in portrait orientation
• 720 x 1280: For smartphones in portrait orientation
