Hi 

Im using intel realsense d415 and d435. 

When i use the 'Intel.RealSense.Viewer'  i want to save the bag file just single frame.

im trying the settings to save ROS Bag file- always compress and I pressed the recording button and immediately stopped it. but i think it saved almost 2 frame. 

It most be high resolution, so i cant change low resolution. 

 

I trying to use VS by C++ or Python, there's no solution to save just 'single frame bag file'.

it does not mean single png and csv file . i want to save .bag file (because i want to open the file using intel RS viewer.... 

 

+ When i open very short bag file then It keeps repeating itself and cannot be stopped.

do you know the solution too? 

Plz help me Thx.

    Hi Ctnam  The Real sense SDK has an instruction called save_single_frameset for saving a single frame as a bag file.  A RealSense user created a Python script for this function at the link below.

    https://github.com/soarwing52/RealsensePython/blob/master/separate%20functions/single_frameset.py

     

    In the bag's controls in the Viewer's options side-panel, a circular arrow option next to the 'Speed: x1' setting is the Disable Repeat option.  Left-click on it to turn its colour from blue (looping is on) to white (looping is off).

    Hi MartyG. Thank you for your help. 
    I'm trying to use 'save_single_frameset' Actually, it's not working out.

    Anyway I load the my bag file and i click the stop button or pause button. 
    I guess the reason... because my .bag file was very short so the it repeat very quickly. It causes a lag.

     

    I'm trying 'Speed x 0.25. stop or pause button, repeat stop all of them. 

    Do you know the solution to show just single frame? or very shorty video?

    Pausing the live stream will not prevent multiple frames from being recorded to a bag file. The best chance of capturing a single frame in the Viewer with your quick stop-start technique may be to set the stream to 6 FPS instead of 30 so that it only captures 6 frames during the period of 1 second.
