RTMP has SO many users for video (Twitch, YouTube etc...) yet you have librtmp which has so many forks. OBS has its own version in-tree....
Then at the same time you have people trying to add extensions to RTMP still!
RTMP has held back the use cases I have cared about since ~2015 so I am excited to see people embrace other options.
I ended up just coding to the OBS source code.
Good riddance to this pile of garbage in as many places as possible, and I don't see what it was doing in curl to start with.
