There is no longer explicit support for the SDL_mixer library.
You can have the SDL mixer library mix audio from a movie by hooking into
the SDL mixer music hooks:
#include "smpeg.h"
#include "SDL_mixer.h"
.. set up the mixer audio ...
/* Note the last parameter is zero! */
mpeg = SMPEG_new("file.mpg", &info, 0);
/* Play the movie, using SDL_mixer for audio */
SMPEG_enableaudio(mpeg, 0);
if ( play_audio ) {
SDL_AudioSpec audiofmt;
Uint16 format;
int freq, channels;
/* Tell SMPEG what the audio format is */
Mix_QuerySpec(&freq, &format, &channels);
audiofmt.format = format;
audiofmt.freq = freq;
audiofmt.channels = channels;
SMPEG_actualSpec(mpeg, &audiofmt);
/* Hook in the MPEG music mixer */
Mix_HookMusic(SMPEG_playAudioSDL, mpeg);
SMPEG_enableaudio(mpeg, 1);
}
SMPEG_play(mpeg);
/* Stop the movie and unhook SMPEG from the mixer */
SMPEG_stop(mpeg);
Mix_HookMusic(NULL, NULL);
