: 在程序端，
使用::criAtomExPlayer_SetFirstBlockIndex函数，为Player指定第一个块索引，
使用::criAtomExPlayback_SetNextBlockIndex函数，为播放ID指定第二个或之后的块索引。

: 播放和控制中途有分支的块Cue的代码如下。
/* 创建Player */

player = criAtomExPlayer_Create(NULL, NULL, 0);

/* 设置块Cue */

player = criAtomExPlayer_SetCueName(acb, "block");

/* 选择第一个块 */

criAtomExPlayer_SetFirstBlockIndex(app_obj->player, 0);

/* 开始播放 */

CriAtomExPlaybackId playback_id;

playback_id = criAtomExPlayer_Start(player);

:

/* 指定下一个块 */

if (status_of_something) {

criAtomExPlayback_SetNextBlockIndex(playback_id, 1);

} else {

criAtomExPlayback_SetNextBlockIndex(playback_id, 2);

}

criAtomExPlayback_SetNextBlockIndex
void criAtomExPlayback_SetNextBlockIndex(CriAtomExPlaybackId id, CriAtomExBlockIndex index)
Set the index of the next block

criAtomExPlayer_SetFirstBlockIndex
void criAtomExPlayer_SetFirstBlockIndex(CriAtomExPlayerHn player, CriAtomExBlockIndex index)
Set the start block (by specifying a block index)

criAtomExPlayer_SetCueName
void criAtomExPlayer_SetCueName(CriAtomExPlayerHn player, CriAtomExAcbHn acb_hn, const CriChar8 *cue_name)
Set the sound data to play (specifying a Cue name)

criAtomExPlayer_Start
CriAtomExPlaybackId criAtomExPlayer_Start(CriAtomExPlayerHn player)
Start the playback

criAtomExPlayer_Create
CriAtomExPlayerHn criAtomExPlayer_Create(const CriAtomExPlayerConfig *config, void *work, CriSint32 work_size)
Create an AtomEx player

CriAtomExPlaybackId
CriUint32 CriAtomExPlaybackId
Playback ID

: 如下面的代码所示，通过使用::criAtomExPlayer_SetBlockTransitionCallback函数，可以在块切换时接收回调。
void main()

{

/* 注册过渡回调 */

criAtomExPlayer_SetBlockTransitionCallback(

app_obj->player, &user_transition_callback_func, app_obj);

}

void user_transition_callback_func(

void *obj, CriAtomExPlaybackId id, CriAtomExBlockIndex index)

{

printf("PlaybackId:%d, BlockIndex:%d\n", id, index);

}

CriAtomExBlockIndex
CriSint32 CriAtomExBlockIndex
Block Index

criAtomExPlayer_SetBlockTransitionCallback
void criAtomExPlayer_SetBlockTransitionCallback(CriAtomExPlayerHn player, CriAtomExPlayerBlockTransitionCbFunc func, void *obj)
Register the block transition callback function
