SDL_mixer 播放wav

环境 vs 2005

编译时需要引入三个库  sdl.lib sdlmain.lib sdl_mixer.lib

以下为源代码

#include <SDL.h>
#include <SDL_thread.h>

#ifdef __MINGW32__
#undef main /* Prevents SDL from overriding main() */
#endif

#include <stdio.h>
#include <sdl_mixer/SDL_mixer.h>
#undef main /* Prevents SDL from overriding main() */

int main(int argc, char *argv[]) {
	SDL_Surface *screen;			//Pointer to the main screen surface
	Mix_Chunk *sound = NULL;		//Pointer to our sound, in memory
	int channel;				//Channel on which our sound is played

	int audio_rate = 22050;			//Frequency of audio playback
	Uint16 audio_format = AUDIO_S16SYS; 	//Format of the audio we're playing
	int audio_channels = 2;			//2 channels = stereo
	int audio_buffers = 4096;		//Size of the audio buffers in memory

	//Initialize BOTH SDL video and SDL audio
	if (SDL_Init(SDL_INIT_VIDEO | SDL_INIT_AUDIO) != 0) {
		printf("Unable to initialize SDL: %s\n", SDL_GetError());
		return 1;
	}

	//Initialize SDL_mixer with our chosen audio settings
	if(Mix_OpenAudio(audio_rate, audio_format, audio_channels, audio_buffers) != 0) {
		printf("Unable to initialize audio: %s\n", Mix_GetError());
		exit(1);
	}

	//Load our WAV file from disk
	sound = Mix_LoadWAV("sound.wav");
	if(sound == NULL) {
		printf("Unable to load WAV file: %s\n", Mix_GetError());
	}

	//Set the video mode to anything, just need a window
	screen = SDL_SetVideoMode(320, 240, 0, SDL_ANYFORMAT);
	if (screen == NULL) {
		printf("Unable to set video mode: %s\n", SDL_GetError());
		return 1;
	}

	//Play our sound file, and capture the channel on which it is played
	channel = Mix_PlayChannel(-1, sound, 0);
	if(channel == -1) {
		printf("Unable to play WAV file: %s\n", Mix_GetError());
	}

	//Wait until the sound has stopped playing
	while(Mix_Playing(channel) != 0);

	//Release the memory allocated to our sound
	Mix_FreeChunk(sound);

	//Need to make sure that SDL_mixer and SDL have a chance to clean up
	Mix_CloseAudio();
	SDL_Quit();	

	//Return success!
	return 0;	return 0;
