Function Documentation

void mp3_close (  struct_audio_data_t *    data )

Closes the decoder. This function must be called when you are done using the mp3 decoder. Parameters: struct_audio_data_t  *data - pointer to the data struct. Definition at line 583 of file mp3.c. References struct_audio_data_t::device, and libao_terminate(). Referenced by audio_decoder(), and audio_terminate().

void mp3_init (  struct_audio_data_t *    data )

Initializes the decoder. This function must be called before audio_play or any atemt to use the mp3 decoder. Parameters: struct_audio_data_t  *data - pointer to the data struct TODO: Return something useful on error instead of reporting a critical error (and possibly die).

Referenced by audio_decoder().

bool mp3_play (  struct_audio_data_t *    data )

Plays a file segment. This function will play a file from the start to the stop that is deinfed in the data struct. Parameters: struct_audio_data_t  *data - pointer to the data struct. Returns: bool - returns false. Definition at line 558 of file mp3.c. References struct_audio_data_t::fdm, struct_audio_data_t::file_name, mp3_decode(), struct_audio_data_t::mutex, struct_audio_data_t::progress, REP_DEBUG, report(), and STRLEN.
