Thread: Can you play audio with SDL_mixer.h without a extra window showing?

I got this code from a wiki that taught me how to make C code that plays audio, and with a few changes I was able to get it to take a command-line argument as the music file name. Here it is

Code:

#include <stdio.h>
#include <stdlib.h>


#include <SDL/SDL.h>
#include <SDL/SDL_mixer.h>


int main(int argc, char *argv[])
{
    if (argc != 2)
    {
        fprintf(stderr, "You must enter 1 argument!");
        exit(1);
    }


    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(argv[1]);
    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(0, 0, 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;
}

The only problem is, even though I guess it needs to create a window to work with SDL, is there any way you could hide it or something so the user can't see it? I don't really want to see it ( I'm planning on running it from Batch files or C applications as an easy way to play an audio file once ), because if I did, I might as well just use a default audio player instead.

Salem, it stops playing the audio completely. That was the first thing I tried. The window doesn't pop up when I call the program, but nothing happens.

Wait, oops, you have to remove the SDL_INIT_VIDEO too? Oh that fixed it, thanks Salem. ( I need to pay more attention when I'm reading )
