camera streaming

"Can you provide me with the example for ultra low latency camera streaming in 4K resolution?"

Thank you in advance

Hey,
here is short example of yaml file for depthai ros driver to get RGB camera to stream at 4K resolution (with minimal other stuff):

/oak: ros__parameters: camera: i_enable_imu: false i_enable_ir: false i_nn_type: none i_pipeline_type: RGB rgb: i_resolution: "4K" i_set_isp_scale: false

You can run launch file with these params by running:

ros2 launch depthai_ros_driver camera.launch.py params_file:=/path/to/configyamlfile.yaml

this should stream 4K video - let me know if you need anything else.

"Thank you for your response, @DaniloPejovic . I attempted the MJPEG streaming example from the DepthAI experiments and connected a Jetson Orin Nano for 4K streaming, but I couldn't achieve a frame rate of 30 fps. Is the Jetson Nano Orin capable of handling four Oak cameras with 4K streaming? Additionally, how can I enable and adjust the super-speed cable for low latency in the code? Lastly, could you provide guidance on using the ROS driver you mentioned?" Here is the streaming example code that I have said Mjpeg streaming

JayendraSaiChakradhar I couldn't achieve a frame rate of 30 fps. Is the Jetson Nano Orin capable of handling four Oak cameras with 4K streaming?

Yes, but your eth bandwidth likely isn't. 4K*30 MJPEG is much more than 1Gbps bandwidth.

Thanks,
