您好我正在Android JNI音頻部分,下面的jni代碼我從Android調用12次根據我的邏輯。只要第一個剪輯播放我發送回撥事件到Android,我再次呼籲selectClip()
播放音頻剪輯。我可以打2次,但在第三次致電申請投擲錯誤爲libOpenSLES Leaving BufferQueue : SL_RESULT_BUFFER_INSUFFICIENT
。 我錯過了什麼嗎? 同樣的任何指針來解決這個問題?作爲libOpenSLES獲取錯誤離開BufferQueue :: Enqueue(SL_RESULT_BUFFER_INSUFFICIENT)
jboolean flag=JNI_TRUE;
jint clipNote = 0;
// select the desired clip and play count, and enqueue the first buffer if idle

jint count)

// sleep logic
while((clock() - t)/1000 < 2000) {
usleep(10000); // sleep for 10ms
}
