Alter contents of chunklist.m3u8

I am interested in adding some additional metadata to the header section of the chunklist.m3u8 files created by Wowza for HLS. Is there an existing interface in the server side API that allows this kind of access? Are there any code/config examples available?

Thanks

Chris

Responding to my own question after a few weeks…

I have found that I can set some minimal metadata in the form of a segment “title”, but I have not found any documentation on this or any other methods so far:

LiveStreamPacketizerCupertino.setTitleStr( String );

Are there any other methods that permit adding data into the m3u8 files?

Are there any limits defined on how long the title string can be?
