Hello, I apologize if this is not the right place, but I was hoping for some guidance on how I could best approach this problem and if GPAC/MP4Box is the right tool for the job. 

What I would like to do is convert an mpegts file that contains a single video stream and a single KLV data stream to CMAF according to [MISB ST1910](https://nsgreg.nga.mil/doc/view?i=5097). What I'm most interested in is mapping the KLV metadata packets into EMSG boxes in the output CMAF. There is a demo [DASH manifest](https://www.mistandards.org/demo/cmaf/data/ST1910.1/H264/cmafsample.mpd) that looks like it was created with GPAC that gives me some hope, but I'm not really sure where to start.
