Public bug reported:

With the fix for bug 1508972, I still can't use the camera on the phone.
When I try to, I see a message like this:

Failed to start viewfinder with format: QVideoSurfaceFormat(Format_RGB32, QSize(960, 540), viewport=QRect(0,0 960x540), pixelAspectRatio=QSize(1, 1), handleType=GLTextureHandle, yCbCrColorSpace=YCbCr_Undefined)
    handleType = QVariant(QAbstractVideoBuffer::HandleType, ) 
     pixelFormat  =  QVariant(QVideoFrame::PixelFormat, ) 
     frameSize  =  QVariant(QSize, QSize(960, 540)) 
     frameWidth  =  QVariant(int, 960) 
     viewport  =  QVariant(QRect, QRect(0,0 960x540)) 
     scanLineDirection  =  QVariant(QVideoSurfaceFormat::Direction, ) 
     frameRate  =  QVariant(double, 0) 
     pixelAspectRatio  =  QVariant(QSize, QSize(1, 1)) 
     sizeHint  =  QVariant(QSize, QSize(960, 540)) 
     yCbCrColorSpace  =  QVariant(QVideoSurfaceFormat::YCbCrColorSpace, )

The issue is that we just don't support video frames being delivered via
a GL texture (we only support software frames). This requires a fairly
significant amount of work in Oxide to be able to share these frames
with the GPU service (thread or process).

Also, the QCamera implementation seems to be relying on qtvideo-node to
supply its texture which means that it doesn't get a texture unless it's
being displayed in the scene graph, which we obviously aren't doing (we
need to instantiate the QCamera outside of QML)
