Hazy camera video on Android

[AkshayFP]

I tried running the declarative-camera project on Android and I get it to work but the camera video is hazy. Screenshot below:

And I keep getting this warnings:

W larative_camer: [SurfaceTexture-0-7528-1] bindTextureImage: clearing GL error: 0x500

How should I make the video output clearer?

Never mind. I had to set the surface format version to 3.0 in main, at the top.

int main(int argc, char *argv[])
{
    QSurfaceFormat f;
    f.setVersion(3,0);

    QGuiApplication app(argc, argv);

    //...
}
