Java多线程声音崩溃

技术标签:
【中文标题】Java多线程声音崩溃【英文标题】：Java Multi-threaded sound crash 【发布时间】：2012-02-26 21:59:00 【问题描述】：我正在开发一个 Java 游戏项目，我需要能够同时实时播放多个声音。我已经实现了一个声音系统，可以生成新线程来播放 SourceDataLine 声音。
游戏在我的电脑上运行良好，但对于我的一位测试人员来说，音响系统会不时出现在他身上的崩溃。我们都在 Windows 7 上运行相同版本的 java (jre 1.6.0_29)，经过几轮测试和谷歌搜索，我无法弄清楚为什么它总是对我很好，但崩溃了在他身上。
这是一个 SSCCE，演示了我的代码中出现问题的部分。重要的部分是 SoundPlayer、Sound 和 SoundThread 类。您需要在保存 SSCCE 的同一目录中包含两个名为 shortSound.wav 和 longSound.wav 的声音文件。

日志文件表明，当声音完成并调用 SourceDataLine.drain() 以清除声音缓冲区中的任何剩余数据时，崩溃发生在声音线程期间。我不确定我做错了什么导致我的测试人员的 jre 在游戏中途崩溃......
您的声音/线程专家的任何见解都会有所帮助。
【问题讨论】：
有几个异常被捕获但未登录到 SoundThread。你确定这不是问题所在吗？ 如需尽快获得更好的帮助，请发帖SSCCE。 Andrew：刚刚为它创建了一个 SSCCE。编辑了我的 OP 以提供它。 Jivings：我更改了那些 try-catch 块以打印异常消息。我正在等待我的测试人员查看异常（如果有）要说什么。 Jivings：我修改代码后，我的测试人员没有收到任何异常信息。它只是崩溃而不抛出异常。 【参考方案1】：可能为时已晚，无法为您提供任何帮助，但以防万一其他人感兴趣 -
在SoundThread::run 中，您正在检查bytesRead，但如果stream.read 返回zero（也许它不应该），那么您将陷入无限循环。
这可能取决于正在播放的声音的精确长度，并且可以解释为什么只有一个人能看到问题。
【讨论】：
【参考方案2】：冒着因为没有直接回答你的问题而被骂的风险，我想提出一个建议。可以创建一个自定义“剪辑”对象，该对象允许多次播放和以不同速度播放。如果 ClipTrack（我的名字）有多个光标，它们的输出可以相加并作为单个音频值发送出去。
我在这里演示了这样的用法： ClipTrack
该站点上有指向 Java 代码的链接，发布在 Java-Gaming.org，欢迎您使用。但是您可能需要大量编辑源代码。我知道我从最初发布它开始。我只是一名中级 Java 程序员，并且正在自学声音。有很多事情应该以不同的方式完成（对象将数据“移交”到我编写的混音器而不是直接播放它 - 但你可以重写它，如果完全不使用 CopyOnWriteArrayList 也可能不是最佳的-可以设计管理游标的阻塞方法）。
但是，至少在那里可以看到基本的想法。 :)
这种方法的潜在好处包括减少线程数。此外，您一次在内存中永远不会有超过一份原始音频数据的副本（而不是在所有剪辑中制作多个副本）。
我发现使用 javax.sound Clips 非常烦人，我很高兴不再纠结于它们。
【讨论】：
你好菲尔。最初，我使用 Clips 播放声音，但大约一半的测试我的游戏的人遇到了 Clips 问题，导致游戏延迟。如果我不能让任何其他工作，我会给你的 ClipTrack 课程一个机会。在花时间学习一个全新的类包之前，我想知道是什么导致我当前的声音线程代码崩溃。【参考方案3】：这是一个不同的答案，我不会修改之前关于编写自定义剪辑的建议（这是一种有效的方法，尽管方法非常不同）。
顺便说一句：我对 SourceDataLine 使用变量名“clip”感到困惑。真的应该重构那种东西！
好的。查看您的代码，您省略了我在播放重叠 SDL 的应用程序中包含的三个步骤。
line.drain();
line.stop();
line.close();
line = null;
aiStream.close();
aiStream = null;
其中“line”是 SourceDataLine，aiStream 是 AudioInputStream。
我认为将这些设置为 null 可能是关键步骤。不确定省略的 stop() 步骤有多重要。我无法确切告诉您为什么需要这样做，但它对我的应用程序产生了影响。
【讨论】：
我会让我的测试员试一试。 这并没有解决问题。 :( 我的测试人员说它仍然在崩溃。 感谢您告诉我。很抱歉，它没有帮助。【参考方案4】：此问题仍未解决。总之，问题可能是发生问题的机器所固有的，并且可能不值得在本机 Java 中进一步研究。
【讨论】：
以上是关于Java多线程声音崩溃的主要内容，如果未能解决你的问题，请参考以下文章
