無法播放使用XUGGLER編碼的音頻

我正在使用此代碼將音頻發佈到red5服務器，並通過發佈商演示測試它，看看我是否能夠聽到我在公開發布的內容。數據包逐漸發送但無法聽到音頻。請幫助我，我無法弄清楚錯誤。無法播放使用XUGGLER編碼的音頻

需要一些幫助與此有關。我已經啓動了Red5服務器，並且當我運行代碼時，它會不斷髮出錯誤'ERROR com.xuggle.xuggler - 錯誤：正在寫入不存在的數據包（../../../。 ./../../../ csrc/com/xuggle/xuggler/Container.cpp：759）' 您是否知道問題所在？ – wrahool

無法發表評論，除非我看到您的代碼。 – Dapu

解決了這個問題，我的麥克風音量非常低，價格爲16kHz，
