Actually orig_width/height is the width/height, width/height is the stride in x/y-axis. > But when trying to allocate the buffer object for it, the width is aligned to > 128 > and height is aligned to 32. It is the requirement of the Y-tiled surface however for linear surface, aligning to 16 byte is enough > If the surface is mapped and accessed You can't map the surface directly, do you mean vaDeriveImage() first then calling vaMapBuffer() to Access the surface ?
