[Red5devs] please help on "writeObject caught NoSuchFieldException"

[Posco, TSO Fung Po]

Hi there,

I want to publish a video clip say, IronMan.flv, to a Red5 server as
an emulated realtime streaming service. But after running
client.invoke("publishStreamData",param,this); I got a :

17:54:26.218 [AnonymousIoService-4] DEBUG org.red5.io.amf.Output -
writeObject caught NoSuchFieldException,

I am very new to Red5 so I have no idea about this exception, could
anyone help? and why client.publishStreamData(streamId, videoMsg);
does not work (that's why I use
client.invoke("publishStreamData",param,this); )

here is the piece of code:

File file = new File("IronMan.flv");
FLVReader reader;
try {
	reader = new FLVReader(file);
	
	while(reader.hasMoreTags()) {
	      ITag tag = reader.readTag();
	      ByteBuffer frame = tag.getBody();
	      VideoData videodata = new VideoData(frame);
	      RTMPMessage videoMsg = new RTMPMessage();
	      videoMsg.setBody(videodata);
	      Object[] param = {streamId,videoMsg};						
	      //client.publishStreamData(streamId, videoMsg);
	      client.invoke("publishStreamData",param,this);
	
	  }
	
} catch (IOException e) {
	e.printStackTrace();
}//end catch

Cheers,
Posco
