Sample description

If you want to synchronize the start of multiple streaming playbacks, use the criAtomExPlayer_Prepare function.

Using the criAtomExPlayer_Prepare function will prepare for playback to start immediately before it can be pronounced.

You can confirm that playback preparation is complete when the playback ID status becomes CRIATOMEXPLAYBACK_STATUS_PLAYING .

(The status when playback cannot start is CRIATOMEXPLAYBACK_STATUS_PREP .)

The playback ID can be obtained as the return value of the criAtomExPlayer_Prepare function, so please keep it in your application.

After playback preparation is complete, to actually start playback, use the criAtomExPlayback_Pause function to cancel the pause for the playback ID.

CriAtomExPlayeBackId playback_id; /* Playback ID */
CriAtomExPlayerHn player;
 
/* Prepare playback */
criAtomExPlayer_SetCueId(player, acb_hn, CRI_ATOMCUESHEET_THUNDER1);
playback_id = criAtomExPlayer_Prepare(player);
for(;;) {
    CriAtomExPlaybackStatus playback_status;
    sleep(1);
    criAtomEx_ExecuteMain();
    playback_status = criAtomExPlayback_GetStatus(playback_id);
    if (playback_status == CRIATOMEXPLAYBACK_STATUS_PLAYING) {
        /* Playback is ready */
        break;
    }
}
 
/* Start playback (resume playback ID) */
criAtomExPlayback_Pause(playback_id, CRI_FALSE);

When you want to synchronize playback start timing, use one player and prepare playback for multiple Voices, then resume the player to start playback together.

In this case, you can determine whether playback is ready or not by checking the status of CriAtomExPlayerHn .

CriAtomExPlayerHn player;
 
/* Prepare playback */
criAtomExPlayer_SetCueId(player, acb_hn, CRI_ATOMCUESHEET_THUNDER1);
criAtomExPlayer_Prepare(player);
criAtomExPlayer_SetCueId(player, acb_hn, CRI_ATOMCUESHEET_THUNDER2);
criAtomExPlayer_Prepare(player);
criAtomExPlayer_SetCueId(player, acb_hn, CRI_ATOMCUESHEET_THUNDER3);
criAtomExPlayer_Prepare(player);
 
for(;;) {
    CriAtomExPlayerStatus player_status;
    sleep(1);
    criAtomEx_ExecuteMain();
    player_status = criAtomExPlayer_GetStatus(player);
    if (player_status == CRIATOMEXPLAYER_STATUS_PLAYING) {
        /* Playback is ready */
        break;
    }
}
 
/* Start playback together (synchronize start timing) */
criAtomExPlayer_Pause(player, CRI_FALSE);
