SMPEG speed problem

SDL Development
1

Hi.
I have a very strange problem playing mpeg videos with the SMPEG component.
Sometimes is played fine and sometimes terribly slow (1-2 fps) without
any aparent reason. The same machine, the same memory and even the same
cpu usage.

I will appreciate any help.
Thanks–

Is your code available anywhere?

I have this code in a separate thread. This is why i put an sleep,
allowing other threads to execute.
I got this code from an example in the Jedi Sdl library.

        SMPEG_setdisplay(SDL_mpeg, surface, nil, nil);
        SMPEG_scaleXY(SDL_mpeg, W, H);
        SMPEG_move(SDL_mpeg, X, Y);
        SMPEG_loop(SDL_mpeg, 1);
        while (SMPEG_status(SDL_mpeg) = STATUS_SMPEG_PLAYING) do begin
            Sleep(10);
        end;

Before any comment I must say that I have tried to play videos without
the Sleep and the problem is still there.

I found the solution! If anyone is interested, audio must have been
initialized before playing videos with smpeg, even if the video doesn’t
have any sound (that was my case).

Thanks everybody!
