我正在做一个项目，我想将数据包写入 RTMP 容器。

  • 我所取得的成就是：

    1. 使用 RED5 启动一个监听 RTMP 请求的应用程序。让我们说 rtmp://localhost/myapp
    2. 我可以使用 IContainerFormat 的输出格式打开 IContainer，例如 ("flv", "rtmp://localhost/myapp/test", null)

  • 出了什么问题：

    1. 我想将数据包写入这个为我打开的 RTMP 通道。
      • 问题是 FFMPEG 开始给出错误 32。与此错误相关的一些搜索表明，这通常是因为客户端 - 服务器数据消耗之间存在滞后。但我真的无法解决这个问题。我搜索了很多，但每个人都在为同样的问题哭泣。我得到的错误是：

12:57:20.242 [Thread-0] 错误 org.ffmpeg - WriteN，RTMP 发送错误 32（129 字节） 12:57:20.246 [Thread-0] 错误 org.ffmpeg - WriteN，RTMP 发送错误 32（45 字节） 12:57:20.246 [Thread-0] 错误 org.ffmpeg - WriteN，RTMP 发送错误 9（42 字节）

这是我在 Red5 服务器上收到的错误

我是媒体流的新手，所以不确定我是否遗漏了什么。

我不认为调试 RTMPProtocolDecoder 的 Java 源代码有不同的机会。

但是不知道你用的是什么Red5版本。

RTMPProtocolDecoder.java:203 => 在最新版本的 Red5/Sources 中，您的异常位于第 147 行： http ://code.google.com/p/red5/source/browse/java/server/trunk/src/org/ red5/server/net/rtmp/codec/RTMPProtocolDecoder.java#147

并且还添加了一些评论。我想你需要做的第一件事就是更新到最新的red5。基于此，您可以调试并寻求更多帮助。

只是为了完成答案。不要依赖 Red5 eclipse 插件，它会生成与 Red 5 1.0RC2 不兼容的代码。Red5 1.0 RC 2 与 red5-web.xml 中的配置更改一起正常工作。该应用程序开始工作，我可以使用 xuggler 在容器上启动一个流。

谢谢@seba.wagner。
