Hi NV support teams:
I use nvsipl_camera to run the simulator mode with a pure raw captured from another sensor,and the raw has the same resolution as the sensor of the sample I run .The result’s print shows that I run it successfully, but I cannot see the picture in display.
I suspect that the raw image used for the simulation is not pure. So could you tell me what the raw data format or the raw data arrangement is in the simulator mode.
