Description
If to use QVideoSink with QCamera and during initialization set camera's format any from available through cameraDevice().videoFormats(), then will be error like:
linking filtered camera to decoder failed camerasrc identity2 "video/x-raw, format=(string)YUY2, width=(int)640, height=(int)480"
But if not set any format to camera, then video output will be seen with some default settings.
In the attachment just look at frames.cpp.
void
Frames::initCam()
{
m_cam = new QCamera( this );
const auto settings = m_cam->cameraDevice().videoFormats();
m_cam->setFocusMode( QCamera::FocusModeAuto );
//m_cam->setCameraFormat( settings.at( 0 ) );
m_capture.setCamera( m_cam );
m_capture.setVideoSink( this );
m_cam->start();
}
Just comment/uncomment
m_cam->setCameraFormat( settings.at( 0 ) );
with any available index.
