Not correct matrix (BT709)

http://www.mathworks.com/help/vision/ref/colorspaceconversion.html
Use conversion specified by = Rec. 709 (HDTV)
1.16438356        0       1.79274107
1.16438356  -0.21324861  -0.53290933
1.16438356   2.11240179       0



Correct matrix:
case GST_VIDEO_COLOR_MATRIX_BT709:
     m_colorMatrix *= QMatrix4x4(
                 1.164,  0.000,  1.793, -0.969,
                 1.164, -0.213, -0.533,  0.300,
                 1.164,  2.112,  0.000, -1.129,
                 0.0,    0.000,  0.000,  1.0000);
     break;
