#### Record and play back with SDK bag
SDK bag recording uses the Orbbec SDK to record device data. It is useful when you want to restart the wrapper later with the recording as a playback device. Record when launching:
```bash
ros2 launch orbbec_camera gemini_330_series.launch.py bag_record_filename:=/tmp/orbbec_record.bag
```
You can also start or stop recording while the node is running:
```bash
ros2 service call /camera/set_bag_recording orbbec_camera_msgs/srv/SetBagRecording "{enable: true, file_path: '/tmp/orbbec_record.bag'}"
```
```bash
ros2 service call /camera/set_bag_recording orbbec_camera_msgs/srv/SetBagRecording "{enable: false, file_path: ''}"
```
Play back an SDK bag:
```bash
ros2 launch orbbec_camera gemini_330_series.launch.py bag_filename:=/tmp/orbbec_record.bag
```
Loop playback:
```bash
ros2 launch orbbec_camera gemini_330_series.launch.py bag_filename:=/tmp/orbbec_record.bag bag_loop:=true
```
