I figured out that Qt creator is using Qt for the OpenCV functions by default. When even running a test code (see below) which opens and shows a camera stream. Here, it is not possible to open the camera (I am using a XIMEA xiQ). With a normal webcam it is working. In Eclipse both is working. Brief summary of steps I have done so far: OpenCV is compiled with XIMEA camera support. I recompiled OpenCV with Qt support. make uninstall for the current installation of OpenCV. make install for the new XIMEA & Qt support enabled installation. My test code: #include "mainwindow.h" #includ. Получение изображения с камеры андроид устройства в программе по wi-fi или USB Добрый день.

The camera is on the front face of the system hardware. For example on a mobile device, it means it is on the same side as that of the screen. Viewfinder frames of front-facing cameras are mirrored horizontally, so the users can see themselves as looking into a mirror. Captured images or videos are not mirrored.  This status indicates the camera device is opened and it's possible to query for supported image and video capture settings, like resolution, framerate and codecs. QCamera::LoadingStatus. 2.  This function was introduced in Qt See also viewfinderSettings(), supportedViewfinderResolutions(), supportedViewfinderFrameRateRanges(), and supportedViewfinderPixelFormats(). [slot] void QCamera::start().

More generally, if a device has more than one embedded camera, is there a way to initialize one of them in particular? If there is no reference to use two cameras, any idea how Samsung did? This class was deprecated in API level We bardware using the new android. In the newer API you have almost complete power over the Android device camera and documentation explicitly advice to.

Non-removable cameras use integers starting at 0 for their identifiers, while removable cameras have a unique identifier for each individual device, even if they are the same model. Howeverthis means if device situation is rare like just 1-frontal -camera tablet you need to count how many embedded cameras you have, and place the order of the camera by its importance "0".

I don't know about a uniform method to identify the frontal camera on all Android devices. Simply said, the Android OS inside the device can't really find out which camera is exactly where for some reasons: maybe open hardware camera qt only camera hardcoded id is an integer representing its importance or maybe on some devices whichever side you turn will be. For the older API it is not recommended, because it will not work on modern phones newer Android version and transfer is a pain-in-the-arse.

Just use the same Integer CameraID 1 to open frontal camera like in this answer :. If you trust OpenCV to do the camera part:. As of Android 2. It is likely that this will be added in a future Android release.

For API 21 5. I could not make it work for API 28 and above. Also, open hardware camera qt the front camera directly is not camega in some devices depends on the manufacturer. With the release of Android 2. Camera class to get the number of cameras, information about a specific camera, and get a reference to a specific Camera.

This technique opsn used when you are using SurfaceView to exploit camera functionality. Very cool post. Took me a while to figure out that camera facing is not neccessarily the same than the camera index.

For example my tablet opeen only one camera index: 0 but facing front facing index: 1. Therefore using the simple code like Camera. Matthias Agree with you mate.
