HI Gianni, There isn't a directly means in the OSG or OpenGL for convention between RGB and YUV. You'll have to convert it on the CPU, or more efficiently create render to texture and post process stage on the GPU that converts the RGB frame buffer to YUV, then copy the resulting RGB frame buffer back to the CPU via a callback and treat it as a YUV.
