Display YUV in OpenGL

Question

I am having trouble displaying a raw YUV file that it is in NV12 format.

I can display a selected frame, however, it is still mainly in black and white with certain shade

Answer 1

I think you're addressing U and V values incorrectly. Rather than:

float U = lookupTableU [uvBuffer [ ((y / 2) * (x / 2) + (x/2)) * 2  ] ]; 
float V = lookupTableV [uvBuffer [  ((y / 2) * (x / 2) + (x/2)) * 2 + 1] ];

It should be something along the lines of

float U = lookupTableU [uvBuffer [ ((y / 2) * (YUV_WIDTH / 2) + (x/2)) * 2  ] ]; 
float V = lookupTableV [uvBuffer [  ((y / 2) * (YUV_WIDTH / 2) + (x/2)) * 2 + 1] ];
