Question

在我的一个小项目上工作，我打算合并一些音乐文件...... 刚刚发现SDL，并认为这将是一个完美的匹配，因为我打算使用.ogg文件。然而......当我尝试加载.ogg文件时... Mix_LoadMUS总是返回NULL ...不知道为什么......

截至目前我的代码：

  int flags = MIX_INIT_OGG | MIX_INIT_MOD;
  int initted = Mix_Init(flags);

  // start SDL with audio support
  if (SDL_Init(SDL_INIT_AUDIO) == -1) {
    printf("SDL_Init: %s\n", SDL_GetError());
    exit(1);
  }

  if (initted&flags != flags) {
    printf("Mix_Init: Failed to init required ogg and mod support!\n");
    printf("Mix_Init: %s\n", Mix_GetError());
    // handle error
  }

  // open 44.1KHz, signed 16bit, system byte order,
  // stereo audio, using 1024 byte chunks
  if (Mix_OpenAudio(44100, MIX_DEFAULT_FORMAT, 2, 1024) == -1) {
    printf("Mix_OpenAudio: %s\n", Mix_GetError());
    exit(2);
  }
  printf("There are %d sample chunk deocoders available\n", Mix_GetNumChunkDecoders());
  printf("There are %d music deocoders available\n", Mix_GetNumMusicDecoders());

  // print music decoders available
  int i, max = Mix_GetNumMusicDecoders();
  for (i = 0; i<max; ++i)
    printf("Music decoder %d is for %s\n",i, Mix_GetMusicDecoder(i));

  Mix_Music *BackgroundMusic;
  BackgroundMusic = Mix_LoadMUS("sounds/Main_Theme.ogg");
  if (BackgroundMusic == NULL) {
    printf("Unable to load Ogg file: %s\n", Mix_GetError()); 
    return 1; 
  }

我做错了什么？

Mix_LoadMUS总是在SDL_MIXER中返回NULL
