Custom FFmpeg Live-Stream Plugin

I need a purpose-built FFmpeg plugin that adds reliable live-streaming capability:

i need a plugin to send fingerprint to live streams, withouth re-encoding/transcoding or using cpu to get this working.

i already have a python script wich is doing it, but it stils re-encoding the stream. i need to have a api /plugin for ffmpeg witch will always work even with copy copy streams.

so there should be nothing encoded/transcoding/rencoded. there should be a new string added inside ff fmpeg binary to get action when we trigger it.

Deliverables

1. Source code for the plugin written in C/C++ (or another FFmpeg-compatible language) and cleanly documented. Budget: USD 10–30 Skills: C Programming, Python, C++ Programming, Software Development, API Development, Video Streaming, Software Engineering
