OrbbecSDK_v2

C++ Sample：2.device.record.nogui

Overview

This example demonstrates how to use the SDK to record video/sensor stream data from an Orbbec camera and output a ROS bag file (.bag). It is a command-line (CLI) tool that records streams directly without rendering video frames.

Knowledge

Pipeline: Manages data streams with capabilities for multi-channel configuration, stream switching, frame aggregation, and synchronization.
RecordDevice: Handles data recording to a ROS bag file, supporting simultaneous capture from multiple sensors and streams.

code overview

Create a Context object and get the specified device.

     std::shared_ptr<ob::Context> context = std::make_shared<ob::Context>();

     auto device = deviceList->getDevice(0);

Instantiate a RecordDevice to capture all streams from the connected device into a ROS bag file:
```
     auto recordDevice = std::make_shared<ob::RecordDevice>(device, filePath);
```

Configure and start the pipeline with a frame callback for real-time preview:

     pipe->start(config, [&](std::shared_ptr<ob::FrameSet> frameSet) {
         std::lock_guard<std::mutex> lock(frameMutex);
         // Do something for frameset
     });

Destroy the RecordDevice to flush and save the ROS bag file:
```
     recordDevice = nullptr;
```
