Sample description

By getting the lower layer Atom player (≒voice) from the voice pool and checking the remaining input data, it is possible to check how much data is being buffered during streaming playback.
Normally, there is no need to be aware of the amount of buffering in an application.
However, if you have a problem with streaming, you may want to check the amount of buffering to investigate.
For example, if the sound is interrupted while the application is running, this corresponds to such a problem.

Processing Procedure

1. Use the criAtomExVoicePool_GetPlayerHandle function to get the Atom player from the voice pool.
2. Use the criAtomPlayer_GetInputBufferRemainSize function to get the remaining input buffer size of the Atom player.

    :
/* Create Voice Pool */
criAtomExVoicePool_SetDefaultConfigForStandardVoicePool(&pool_config);
pool_config.num_voices = SMP_MAX_STREAMS;
pool_config.player_config.streaming_flag = CRI_TRUE;
app_obj->pool = criAtomExVoicePool_AllocateStandardVoicePool(&pool_config, NULL, 0);
    :
 
    :
/* Get information about the Atom player (nearly equals to Voice) in the Voice Pool */
for (i = 0; i < SMP_MAX_STREAMS; i++) {
    /* Get the Atom player */
    player = criAtomExVoicePool_GetPlayerHandle(app_obj->pool, i);
 
    /* Get status/amount of buffering in the Atom player */
    status = criAtomPlayer_GetStatus(player);
    nbyte = criAtomPlayer_GetInputBufferRemainSize(player);
        :
}
    :

Attention

If the buffering amount remains at 0 for a long period of time even though the Atom Player status is CRIATOMPLAYER_STATUS_PLAYING , file loading may be blocked by some process.
