Hello,

I guess you’d have to do it in the muxer if you can. For eg. the ffmpeg allows you to set some options:

[https://www.ffmpeg.org/ffmpeg-formats.html#Options-6](https://www.ffmpeg.org/ffmpeg-formats.html#Options-6)

If that’s not enough you could patch it to add other options:

I’m not aware of a way to modify the packets directly in Wowza as it’s quite low-level. I would like to know as well if it’s possible.
