Detailed Description

Configuration for opening a camera device via FFmpeg.

Platform device string conventions:

• Linux: "/dev/video0", "/dev/video1", …
• macOS: "0" (AVFoundation device index) or a camera name such as "FaceTime HD Camera"; frame rate must equal a rate range maximum
• Windows: "video=Integrated Camera" (DirectShow filter name)

Resolution, frame rate and input format are hints. If the device rejects them, open() retries without the input format, then without frame rate, then with device defaults. The negotiated values are available from FFmpegCameraReader after open().
