Reolink PTZ Streamer

Reolink PTZ Streamer

This program is a PyQt6 application that allows users to view and control a Reolink PTZ (Pan-Tilt-Zoom) camera. It was written for a TrackMix camera which has two lenses. It displays two video streams from the camera and provides controls for moving the camera and zooming.

Features

• Displays two video streams from the camera: wide-angle and telephoto
• Allows camera movement using arrow keys
• Supports zooming using the mouse wheel
• Reads camera configuration from a file

Dependencies

• PyQt6
• reolinkapi

Usage

1. Ensure you have a camera.cfg file in the same directory as the script with the following structure:

[camera]
ip=<camera_ip>
username=<username>
password=<password>

2. Run the script:

python script_name.py

Classes

ZoomSlider

A custom QSlider that ignores arrow key events.

CameraPlayer

The main widget that displays the video streams and handles user input.

Methods

• __init__(self, rtsp_url_wide, rtsp_url_telephoto, camera: Camera): Initializes the widget and sets up the video streams.
• keyPressEvent(self, event): Handles key press events for camera movement.
• keyReleaseEvent(self, event): Handles key release events to stop camera movement.
• start_move(self, key): Starts camera movement based on the pressed key.
• stop_move(self): Stops camera movement.
• move_camera(self, direction): Moves the camera in the specified direction.
• handle_wheel_event(self, event: QWheelEvent): Handles mouse wheel events for zooming.
• zoom_in(self): Initiates zooming in.
• zoom_out(self): Initiates zooming out.
• start_zoom(self, direction: str): Starts zooming in the specified direction.
• stop_zoom(self): Stops zooming.
• show_error_message(self, title, message): Displays error messages.
• handle_error(self, error): Handles media player errors.

Main Execution

The script performs the following steps when executed:

1. Reads camera configuration from camera.cfg.
2. Connects to the camera using the provided credentials.
3. Creates RTSP URLs for wide-angle and telephoto streams.
4. Initializes the QApplication and CameraPlayer.
5. Displays the CameraPlayer widget.

Notes

• The script disables SSL warnings for self-signed certificates.
• Error handling is implemented for various camera operations.
• The camera movement and zoom operations are designed to work with Reolink cameras that support the PTZ API.
