If LGPL suites you, you can fork of the existing muxer ?

https://gitlab.freedesktop.org/gstreamer/gstreamer/-/tree/main/subprojects/gst-plugins-good/gst/flv

What I would do though, is see if I can add some callback to the existing muxer,
that would let me modify the AMF, or add more AMF blocks where needed. I could
even think that AMF utilities could be made, similar to RTP packets utility, so
you could implement custom messages for your custom stream server. After all,
RTPM is just an IPC using AMF to communicate.
