Hello,
i managed to run Gmsl2 Camera with Imx728 Image Sensor by starting the “sample_application” using DriveWorks SDK 5.10. The Camera is streaming at 30fps. For synchronization with other sensors, I would like to ask if we can control the camera or send a signal to the camera in a way so that the camera can capture the image frame on my demand?
Thank you in advance for your support

No. It is not possible.

Hi SivaRamaKrishna,
thank you for your reply!
as i understand correctly, once the driveworks “sample_camera” app is called, the camera will always outputs images at 30fps. In the main.cpp of the “sample_camera” it does contains the onKeyDown() function, by which the user can “pause” the camera by pressing Key “P” + "Camera Index ". I try it and the application completely freezes and the camera cannot resume streaming even though i press Key “O” + Camera Index. My Question is why pressing the “P” button causes the application to crash instead of “pausing” the camera?

Dear @buva5871,
You have entered P+0 or P0 or P 0 for deal with camera 0? Do you see any output on terminal after pressing the keys?

Hi SivaRamaKrishna,
I pressed “P 0” to pause the camera 0. I did see the outputs “Pausing sensor 0” and the camera stopped. Then i tried to resume the camera by pressing “O 0” on the keyboard. This time i didn’t see any message outputs and the application froze. I assume that the camera should stream the images when i press the “O 0” button?

Dear @buva5871,
We can reproduce the issue. We check internally and update you.

Dear @buva5871,
Start Camera → Stop Camera → Start Camera is an un-supported sequence by NvMedia. So It is expected not to work.

Can you please explain why we can not provide fsync signal in 6.0.6 to capture with external pulse ? below 6.0.6 document mention that feature.
