Hi, I have linked theora and ogg libs into an OpenGL game engine. I have successfully decoded a frame to the YUV buffer, and then converted that to RGB. I really want to use alpha channels in the ogg movies. Does the yuv_buffer structure support alpha channels? Any advice on how to get an RGBA buffer would be greatly appreciated.
