Describe the issue

My setup

I'm using mediamtx as a middleman for loading an RTSP stream into my react frontend.
I'm using my own backend as an external authentication server.
It expects to receive a token in the query field of the payload.
Reading and writing should be in this format. Some/Extended/Path?token=SecretToken

The problem

I can publish an RTSP stream fine using ffmpeg with the token, but I can't read it again with WebRTC.
When I unmarshal the payload in my backend, I can see that the query field is an empty string.
I've found that it works with release v1.2.1, and breaks with v1.3.0.

The only difference I can see in the logs, is that with v1.3.0, the token seems to disappear after the server makes a 301 redirection.
And for some reason, it transforms my path into Some/Extended/Some/Extended/Path from Some/Extended/Path, but I'm guessing this is just a formatting change.

Let me know if you need more information.

Describe how to replicate the issue

1. configure server to use external authentication server
2. start external authentication server, that accepts token in query from payload
3. start the mediamtx
4. publish with ffmpeg with a token as a query parameter (works)
5. read with webrtc with a token as a query parameter (fails)

Did you attach the server logs?

yes
