Dear @Sandys9995,
Please check GMSL camera sample in DriveWorks. In onprocess() function, dwSensorCamera_readFrame() reads each frame from camera/video for further processing. Please see if your simulated frames can be used here directly for further processing.
If you are referring to drivenet sample, Add code snippet in getNextFrame() to get your simulated data instead of camera/video frame data.
For drivenet output recording, see the discussion on How to save the output video of DNN samples in host-pc if it helps.
