QUESTION

OpenCV returns no error when open is called, but gstreamer does

Asked 2022-Jan-11 at 18:17

I have the problem when I open a camera with GStreamer, and the camera is not connected, I don't get an error code back from OpenCV. GStreamer returns an error in the console. When I check if the camera is open with .isOpend() the return value is true. When the camera is connected, it works without any issue.

This may just be because of a typo. nvarguscamerasrc has no property sensor_id but has sensor-id. It should work after fixing this.

In not working case, cap.read() should return false.

QUESTION

OpenCV Docker multistage build - cannot install prebuilt source

Asked 2020-Sep-15 at 06:48

I'm trying to build a Docker image including a very particular configuration of OpenCV with CUDA and GPU support.

The build succeeds, and if I make install it from the same context that built the image, it works with no problems.

The problem happens when I try to use a multi stage build, to avoid keeping all the dependencies needed to build OpenCV. Before you continue reading, what follows might actually be an XY problem, if you have a better solution on how to copy OpenCV build artifacts (including Python bindings!) in a Docker multistage build, that is my actual intent.

Now for my attempted solution and the struggle I have:

I run COPY --from=requirements /opencv /opencv and it works and it apparently copies everything in the right path (I checked the filesystem). But, when I run from the build folder make install, I get this CMake error:

It is simpler to run cmake & make and make install in the same stage and then copy the install folders. It will allow to not have any build tools like cmake or build-essential in the final docker image.

We will use a custom CMAKE_INSTALL_PREFIX so that OpenCV binaries are installed to a directory and we can copy it straight to the next stage. Using a custom prefix will avoid having to copy CUDA installation or development libraries no longer required. Then we will run ldconfig on that directory to link the libraries as usual.

Modify the build script to use a custom CMAKE_INSTALL_PREFIX:
