QCameraViewfinder class in not available in Qt 6

[@estilay]

Thanks for your videos, I really appreciate your work! Is it possible to connect ip camera with Qt and don't use other libraries such as opencv? I've read about QNetwotk, but it didn't help so much and I didn't find any solution without using libraries. 😔

[@qtwithketan]

Thanks for watching my video. Glad you like my video.
Right now i don't have IP camera to check so i will not give you any wrong way or solution.
Try to readout following links:

It too awesome solution sir. I have an Question: I have 3 (USB) different capture card connected to computer and i want to connect very specific as you told we have to change your camera from QCameraInfo::defaultcamera(). so how can i connect it from qt5 ++?

[@qtwithketan]

Glad you like my videos.
To Connect any specific camera. you can use devicename of your camera.
You can follow The below Code.
for (const QCameraInfo &caminfo : QCameraInfo::availableCameras())
{
if (caminfo.deviceName() == "YOUR_DEVICE_NAME")
{
M_Camera.reset(new QCamera(caminfo));
break;
}
}

Did you include the Qt Multimedia plugins in your application ?

[@thirumala8065]

Yes sir. I have added. I found the issue sir. Actually Ubuntu is not identifying the camera. Webcams options is not coming in virtual box. And this is my office laptop, so need admin permissions to change cam settings in ubuntu.

[@cyril442]

Thank you for video. Do you know how to connect IP-camera using URL-link?

[@qtwithketan]

Thanks for watching my video.
I sugget you to use your camera SDK For it.
And Also you can use Qt Network And Qt Multimedia Module classes for it.

[@zergap1]

Thank you so much. Studying Qt has been very helpful. I’m looking forward to more videos. Please let me know if there’s a way to develop in vscode.

VSCode Is source-code editor software which mostly used to write the code easily because of syntax highlighting, intelligent code completion, snippets, code refactoring functionality.

[@herbirsey3174]

These are the codes I wrote; I have classes named btnitemdelegate, mainpage and update. The signal goes from the btnitemdelegate class to the mainpage class with a parameter. I send a signal from the mainpage class to the update class with a parameter. I want you to do this here; How can I include the .h files of these classes with each other? I also want to send a signal from the update class to the mainpage class again. How can I do that? What I really want is; Learning how to include .h files with each other?

[@qtwithketan]

Thanks for watching my video.
if i am right you want to call signal and slot function across thi multiple class and you want to learn how to include .h file to fulfill this functionality.

[@herbirsey3174]

@@qtwithketan Yes Please, The other situation is this; When the click event on class A is triggered, I want to pass a QModelIndex parameter to class B. I couldn't find how to do this. Thanks

[@qtwithketan]

just simply create signal in your Class A and emit The signal with your QModelIndex parameter on your click event, now just create and connect your class A signal with your any slot function with QModelIndex Parameter of class B, so whenever click event called that time you class B slot function is automatically called.

[@herbirsey3174]

Thank you very much@@qtwithketan

Are you using Qt5 or Qt6? I have trouble promote QCameraviewfinder on qt6

[@qtwithketan]

Thanks for watching my videos.
I am using Qt5 And Version is Qt 5.15

[@AmanKumar-cz6ht]

i am also facing the same issue of QCameraviewfinder in qt6. But works fine in qt5. But still not able to understand why QCameraviewfinder is not working in qt6 can you tell me bit about QCameraviewfinder what is main use of this. Thanks in advance

[@qtwithketan]

Thanks for watching my videos.
In Qt6 You can develop this funtionality with use of QVideoWidget And QMediaCaptureSession.
QCameraviewfinder is also Inherit by QVideoWidget.

[@AmanKumar-cz6ht]
