Newbie question on animation

SDL Development
1

Hello, I’d like to show a short mpeg movie or flic in a loop on the
main screen and at the same time blit some images over. Can anyone
point to me what libraries to use? I’m just beginning to use SDL but
just the standard libraries.

Thanks

I’d probably do this:

  • Use “SMPEG” library
  • Have it blit to an off-screen surface
  • Whenever I have a chance, copy from that surface to the main window
  • Blit my own junk on top of it, on the main window
  • SDL_Flip() or SDL_UpdateRect() to make it display

You could get SMPEG to blit directly to your main window’s surface, but
I think you’ll need to worry about timing a little bit more.
(By the time you’re done blitting your own stuff on top of the MPEG video,
SMPEG might blit a new frame :^) )

Good luck!On Fri, Jul 08, 2005 at 11:18:07AM -0700, Javier Soques wrote:
