hi I want to capture video from a webcam and aply a ShaderEffect on it, but i cannot get the resolution higher than 640×480

does anybody know if this is even possible?

 

        Camera {
            id: camera

            captureMode: Camera.CaptureVideo
            videoRecorder {
                resolution:Qt.size(1280,720)
                frameRate: 30
            }
        }

Hi Bas!

I get the same problem if I try to change the resolution when using the camera – pictures and videos are always 640 x 480.
Maybe you have more luck by directly using the C++ Camera types. I think they offer more features than the QML versions. When quickly trying the C++ Camera example by Qt, I at least got to change the resolution of captured camera images. (No luck with the video though)

Best,
Günther

Hi Günther,

hmm that is a pitty, and weird,full HD is pretty much standard.

will have a search through the QT forums.

i will have a throw at QTAV:

maybe they solved this problem.

Good idea! If you find anything useful – can you also share it here?
Just in case somebody else also needs this in the future 😉

Best,
Günther
