MR_PLAT_VALUE_BASE + 设备状态值 成功
MR_FAILED 失败
MR_WAITING 异步模式,需要使用ACI_STATUS命令轮询以获取状态
MR_IGNORE 不支持该功能
返回成功得到状态,其枚举值为:
typedef enum tag_PLAY_STATE
{
MR_MEDIA_IDLE= 1001, /*1.not init; 2.device closed*/
MR_MEDIA_INITED = 1002,
MR_MEDIA_LOADED = 1003, /*1.loaded not play; 2.play finished; 3.play stoped*/
MR_MEDIA_PLAYING = 1004, /*1.playing*/
MR_MEDIA_PAUSED = 1005, /*1.paused*/
MR_MEDIA_SUSPENDED = 1006,
MR_MEDIA_SUSPENDING = 1007
}PLAY_STATE;
platEx(209x),其中x代表音频类型的枚举值:
typedef enum tagT_MEDIA_TYPE
{
MEDIA_MIDI = 1,
MEDIA_WAVE,
MEDIA_MP3,
MEDIA_AMR,
MEDIA_PCM,
MEDIA_M4A,
MEDIA_AAC,
MEDIA_LYRIC,
MEDIA_UNKNOW
}T_MEDIA_TYPE;
