OpenGL YUV_>RGB matrixes are slightly not precise enough

mplayer2, VDPAU and CoreVideo use:

1.164384e+00 0.000000e+00 1.596027e+00 -8.742022e-01
1.164384e+00 -3.917623e-01 -8.129676e-01 5.316678e-01
1.164384e+00 2.017232e+00 0.000000e+00 -1.085631e+00

instead of

{ 1.1640,  0.0000,  1.4030, -0.7773 },
{ 1.1640, -0.3440, -0.7140,  0.4580 },
{ 1.1640,  1.7730,  0.0000, -0.9630 },

And

 1.164384e+00 0.000000e+00 1.792741e+00 -9.729451e-01

 1.164384e+00 2.112402e+00 0.000000e+00 -1.133402e+00

instead of
