I am working on a project, I want to write packets on to an RTMP container.

  • What I have achieved is:

    1. To start an app which listens for RTMP requests using RED5. Lets say rtmp://localhost/myapp
    2. I could open IContainer with IContainerFormat’s output format give as (“flv”, “rtmp://localhost/myapp/test”, null)

  • Whats going wrong is :

    1. I want to write packets on to this RTMP channel that is opened for me.
      • Issue is FFMPEG starts giving error 32. A bit of search related to this error showed that this is happens usually because there is a lag between client – server data consumption. But I really was not able to solve this issue. I have searched a lot but everyone is crying about the same issue. The error i get is :

12:57:20.242 [Thread-0] ERROR org.ffmpeg – WriteN, RTMP send error 32 (129 bytes)
12:57:20.246 [Thread-0] ERROR org.ffmpeg – WriteN, RTMP send error 32 (45 bytes)
12:57:20.246 [Thread-0] ERROR org.ffmpeg – WriteN, RTMP send error 9 (42 bytes)

And this is the error i receive on Red5 Server

I am new to media streaming, so not sure if I am missing something.

Thanks in advance.

    I don’t think that there is a different chance then debugging the Java Source code of RTMPProtocolDecoder.

    But I don’t know what Red5 version you are using.

    RTMPProtocolDecoder.java:203
    => In the latest version of Red5/Sources your exception is in line 147:
    http://code.google.com/p/red5/source/browse/java/server/trunk/src/org/red5/server/net/rtmp/codec/RTMPProtocolDecoder.java#147

    And also added with some comments. I guess first thing you would need to do is to update to latest red5. Based on that you can then debug and ask for more help.
