It seems that I can use stream.senddirect() to insert an AMF onTextData to the stream and then use the ModuleCupertinoVODOnTextToID3 module to convert the inserted onTextData events to ID3 tags.
My question is: This article only describes how to insert ID3 tags during streaming. Can I insert ID3 tags to the .ts segment? ( ideally the wowza should create a new .ts file with an ID3 tag inserted at 3s ). Is this possible?
