Custom metada and record live stream

Question

I tried to inject my own metadata into a live stream (webcam) recorded on FMS 4.5.1
with no success. I was able to change only the standard metadata but not all my custom ones were recorded
despite of all example on adobe livedocs, no luck.(as2 and as3)
this example
http://help.adobe.com/en_US/flashmediaserver/devguide/WS5b3ccc516d4fbf351e63e3d11a0773d56e -7ff6Dev.html
doesn't work at all for custom metadat and EVEN recroded special metadata like createdby and creationdata
example:
metaData.createdby = String(streamTitle + " of "+fullName);
metaData.creationdate = String(now.toString());
metaData.tags = {createdby:metaData.createdby, creationdate:metaData.creationdate};
metaData.width = Number(devicesQuality.width);
metaData.height = Number(devicesQuality.height);
nodeSendStream.send("@setDataFrame", "onMetaData", metaData);
once the stream is recorded I can see only metData.width and height. createdby, creationdate and tags don't exist.
notice: I encode and stream from FP11.1 in H2564 with speex or pcmu
Thanks

Answer 1

well,
I exactly respected the example of the link you gave by modifying the Application.xml, but if it was a segment problem
how can you explain that the NON custom metadas are successfully modified ?
please check this link

I even tried the official property called createdby and creationdate without success. I was able to change only  width and height
the code I use from the client is exactly the example of adobe manual, in AS2 and AS3
Thanks
