AstraLogi Recorder

A C++ application for simultaneously previewing and recording video streams from an Orbbec Astra camera and a standard UVC webcam (like a Logitech). It captures RGB, Depth, and IR streams from the Orbbec camera and an RGB stream from the UVC camera, displaying them in a 2x2 grid with timestamps.

Features

• Displays four video streams in a single window:
  • Orbbec Astra: RGB
  • Orbbec Astra: Depth (colorized)
  • Orbbec Astra: IR
  • Logitech Webcam: RGB
• Overlays the current system time on each video stream.
• Simple GUI with "Start Rec" and "Stop Rec" buttons.
• Records each stream to a separate AVI file in the recordings directory.
• Gracefully saves recordings if the application is closed while recording is active.

Dependencies

To build and run this project, you will need the following installed:

• A C++11 compatible compiler (e.g., g++)
• CMake (version 3.10 or higher)
• OpenCV
• Orbbec SDK v2

Build Instructions

1. Clone the repository:

   git clone <your-repository-url>
   cd AstraLogiRecorder

2. Create a build directory:

   mkdir build
   cd build

3. Run CMake and Make:

   cmake ..
   make

   This will generate two executables: AstraLogiRecorder and list_profiles.

Usage

1. Connect Hardware: Ensure both your Orbbec Astra camera and your Logitech (or other UVC) webcam are connected to your computer.

2. Run the Application: Navigate to the build directory and run the executable:

   ./AstraLogiRecorder

3. Controlling the Application:

   • A window will open displaying the four camera feeds.
   • Click the "Start Rec" button to begin recording all streams. A red circle will appear in the bottom right to indicate that recording is active.
   • Click the "Stop Rec" button to stop recording.
   • To close the application, press the 'q' or 'Esc' key while the application window is in focus.

Recordings

• All recorded videos are saved to the recordings directory within the project's root folder (AstraLogiRecorder/recordings/).
• The files are named with the stream type and the timestamp of when the recording was started, for example:
  • orbbec_rgb_2025-07-17_12-15-30.avi
  • orbbec_depth_2025-07-17_12-15-30.avi
  • orbbec_ir_2025-07-17_12-15-30.avi
  • logitech_rgb_2025-07-17_12-15-30.avi

Utility

The list_profiles executable can be used to check the available stream resolutions and formats for your connected Orbbec device. This is useful for debugging or modifying the stream configurations in main.cpp.

./list_profiles
