How to open csi camera in a docker container

[AnhHazz]

Hi @dusty-nv
I'm using a ros:humble docker container which is not a ros_deeplearning container and I want to send camera images through ros2 topic. The problem is this container doesn't have nvgstreamer so I can't use:
std::string gstreamer_pipeline (int capture_width, int capture_height, int display_width, int display_height, int framerate, int flip_method) { return "nvarguscamerasrc ! video/x-raw(memory:NVMM), width=(int)" + std::to_string(capture_width) + ", height=(int)" + std::to_string(capture_height) + ", framerate=(fraction)" + std::to_string(framerate) + "/1 ! nvvidconv flip-method=" + std::to_string(flip_method) + " ! video/x-raw, width=(int)" + std::to_string(display_width) + ", height=(int)" + std::to_string(display_height) + ", format=(string)BGRx ! videoconvert ! video/x-raw, format=(string)BGR ! appsink"; }

std::string pipeline = gstreamer_pipeline(capture_width, capture_height, display_width, display_height, framerate, flip_method); std::cout << "Using pipeline: \n\t" << pipeline << "\n";

cv::VideoCapture cap(pipeline, cv::CAP_GSTREAMER);

Is there any way I can use the csi camera?
As I know, camera devices always have their name inside /dev folder so we can read from the device. i searched but haven't found where csi camera in that folder. I only found /dev/video0. Is that it? Tks for helping!

Hi @AnhHazz, the /dev/video* devices are for V4L2 interface, instead the Argus CSI daemon communicates over this socket mounted into the container:

jetson-inference/docker/run.sh

Line 205 in 644f515

-v /tmp/argus_socket:/tmp/argus_socket \

@dusty-nv Thanks for reply i see, but i still don't know what to do. Can you tell me exactly what steps in order to run the csi camera inside a container? Or how to install nvgstreamer inside the container?

I don't use your docker images so those nvgst commands are not available now

@AnhHazz I think you need to have gstreamer installed inside the container and be using --runtime nvidia to enable the nvidia plugins for gstreamer
