Comment (by Balling):

 So I fixed SMPTE 240M matrix in 3249b963421cf5ff0e6adf2e38c86194fdf50929.
 Now, the problem as I said is in that code. SDL does not support 444
 chroma correctly and that means that in SDL_SetYUVConversionMode(mode)
 mode will be set to SDL_YUV_CONVERSION_AUTOMATIC, which has different
 behaviour on linux and windows. On linux the sample here is correctly
 decoded because the length is correct amount of pixels for BT.601. Now, on
 windows it does not select BT.601, but BT.709. Who knows why?
