Mondain, Art or other semigod! Helping on metadata for live h264 publisher.

It's known by everyone that i am working on a opensource live encoder, it's ugly and dirty code for now, just to figure the work, after this, i'll rewrite everythin on a beauty code.

Please, may I give a bit of your attention?

I am writing a publisher of H264 live content, and I am having problems with metadata.

I got the packets generated by other "well known encoder" that comes to "ClientBroadcastStream" and deserialized them.

I maked a "reverse" of this, serializing the new packets.

When packet arrive client (the publisher application) I got: "19:52:45:911 - Asynchronous code error - ReferenceError: Error #1069".

Have you seen this error?

I never created a packet from scratch on my whole life, so, it's possible that the error is obvious.

_client is a simple RTMPClient with "published" state (some code from StreamingProxy).

Look my created packet:

            Notify createdNotify = new Notify();

            IoBuffer buf2 = IoBuffer.allocate(1024);
            buf2.setAutoExpand(true);
            Output out2 = new Output(buf2);

            out2.writeString("@setDataFrame");
            out2.writeString("onMetaData");

            Map<Object, Object> props2 = new HashMap<Object, Object>();
            props2.put("videokeyframe_frequency", (java.lang.Integer) 5);
            props2.put("videodevice", "Microsoft LifeCam VX-1000");
            props2.put("keywords", "");
            props2.put("width", (java.lang.Integer) 320);
            props2.put("videodatarate", (java.lang.Integer) 200);
            props2.put("presetname", "Medium Bandwidth (300 Kbps) - H.264");
            props2.put("copyright", "");
            props2.put("creationdate", "Mon Jul 06 18:22:19 2009\n");
            props2.put("videocodecid", (java.lang.Integer) 4);
            props2.put("author", "");
            props2.put("title", "");
            props2.put("height", (java.lang.Integer) 240);
            props2.put("description", "");
            props2.put("rating", "");
            props2.put("framerate", Double.parseDouble("15"));


            out2.writeMap(props2, new Serializer());
            buf2.flip();

            createdNotify.setData(out2.buf());
            RTMPMessage msg2 = new RTMPMessage();
            msg2.setBody(createdNotify);

            _client.publishStreamData(streamId, msg2);
