You will be able to achieve far more with your ZR300 if you use the RealSense SDK For Linux. This is an SDK that Intel made specially for ZR300. It includes the legacy Librealsense in its packages so you can access its capabilities, and also adds many extra features not in Librealsense, such as object and person detection.
RealSense SDK For Linux has record and playback, and a Capture tool that "Provides a GUI to view camera streams, create a new file from a live camera, and play a file in the supported formats. The tool provides options to render the camera or file images".
Thank you, i installed realsense_sdk and tried to build and access recording folder. I thought i can obtain images from some libraries. As your suggestion, i have to write my own codes using this API or SDK aright?
Because Im not familiar with linux and C, some steps for executing details from realsense_sdk may lose.
I have not used RealSense SDK For Linux myself, so I apologize if my suggestions here are unclear. It looks as though you are viewing the folder where the source-code version of the samples is stored.
The instructions suggest that pre-built executable versions of the samples are provided as well, and may be in a folder called usr / bin
