Is it possible to draw an image onto the screen using SFML, but not usin OpenGL at all? I'm asking that because i'm streaming some video using theora and i figure uploading the video frame through gdi(on windows) for example would be much faster than uploading it to video memory as a texture, on older less powerful video cards. Can i do this? If not is there a way i can access the hdc for example so i can implement this?
