      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.
