Mp3 music with SDL_mixer

SDL Development
1

I’m using SDL_mixer to play mp3 music. The music,
however, does not loop.

The same code loops just fine when I feed Mix_LoadMUS()
a .wav file, but mp3s stop playing after the first run.

My code is pretty basic:

Mix_Music *music = Mix_LoadMUS( argv[1] );
Mix_PlayMusic( music, 2 );
sleep( 1000 );

I know that Heroes3 loops mp3s. Anybody know what I’m
missing?

Thanks,

Perhaps the wav-file only loops because it has a loop defined (which
wav-allows), not because of some SDL_mixer-specialty. Mp3, AFAIK,
does not have the option to define loops, or your file does not use this,
if it were possible. That would mean you have to restart playing yourself,
preferably via some end-of-play-callback-function.

Question for the Loki guys: Does Heroes3 use SDL_mixer to
load/play mp3 music, or does it use smpeg directly?

It uses the Mixer to play MP3s, thru SMPEG. Actually the SMPEG support
to the mixer was added for this game :-)–
