示例描述

: 在CRI Atom中，可以从AWB文件直接播放音频数据。

: 从AWB文件流播放音频数据的代码如下。
CriAtomExAdxVoicePoolConfig voice_pool_config;

CriAtomAwbHn awb_hn;

CriAtomExPlayerHn player;

/* 创建AWB句柄 */

awb_hn = criAtomAwb_LoadToc(NULL, PATH AWB_FILE, NULL, 0);

/* 使用预设值初始化创建Voice池的参数 */

criAtomExVoicePool_SetDefaultConfigForAdxVoicePool(&voice_pool_config);

/* 由于要从AWB文件执行流播放，启用流播放 */

voice_pool_config.player_config.streaming_flag = CRI_TRUE;

/* 创建可执行流播放的Voice池 */

voice_pool = criAtomExVoicePool_AllocateAdxVoicePool(&voice_pool_config, NULL, 0);

/* 创建Player */

player = criAtomExPlayer_Create(NULL, NULL, 0);

/* 指定WaveID */

criAtomExPlayer_SetWaveId(player, awb_hn, 0);

/* 开始播放 */

criAtomExPlayer_Start(player);

criAtomExPlayer_Start
CriAtomExPlaybackId criAtomExPlayer_Start(CriAtomExPlayerHn player)

: ::criAtomExPlayer_SetWaveId函数的第三个参数是AWB文件中的音频数据索引。

: 上述代码示例表示的是流播放的情况，也可以将AWB文件读取到内存中，使用::criAtomAwb_LoadFromMemory函数从AWB文件映像中创建AWB句柄，执行内存播放。
