video data is stored contiguosly, 8 bits for sample. No special meaning for any bit in a given sample. It would be nice to have pixel buffers page-aligned (speed reasons), but this requisite isn't strictly enforced yet.
So, let us say I have a Y value of 213 (in decimal). If I want to put that value into the vframe_list structure's video_buf_Y member array, can I just say:
ptr->video_buf_Y[0][pixel arithmetic] = 213; //? Or, would I have to do a conversion, for example, int Y = 213 - 128; ptr->video_buf_Y[0][pixel] = Y; or int Y = 213; ptr->video_buf_Y[0][pixel] = (char)Y; or something like that? -- James G.
