Describe the issue

When attempting to stream video with RTSP (using Gstreamer), response 400 is given on SETUP request.

Describe how to replicate the issue

1. Launch MediaMTX with the following config: mediamtx.yml

Docker command I'm using is docker run --restart unless-stopped -v ./src/mediamtx/mediamtx.yml:/mediamtx.yml -v ./src/mediamtx:/app/data -p 8554:8554 -p 1935:1935 -p 8888:8888 -p 8889:8889 -p 8890:8890/udp -p 8189:8189/udp bluenviron/mediamtx

2. Stream a test video using Gstreamer (v1.22.10), observe the connection has no issues
   gst-launch-1.0 videotestsrc ! videoconvert ! videoscale ! video/x-raw,width=640,height=480 ! x264enc speed-preset=veryfast tune=zerolatency bitrate=800 ! rtspclientsink protocols=tcp location=rtsp://127.0.0.1:8554/mystream
3. Stream a test video using Gstreamer, with sample query parameters
   gst-launch-1.0 videotestsrc ! videoconvert ! videoscale ! video/x-raw,width=640,height=480 ! x264enc speed-preset=veryfast tune=zerolatency bitrate=800 ! rtspclientsink protocols=tcp location=rtsp://127.0.0.1:8554/mystream?key=value
4. Observe the response: Error (400): Bad Request

It seems fine until Gstreamer tries to send data to the /mystream/stream=0 endpoint.

Additional info

The reason I need to send a query parameter is for JWT authentication; as specified in the docs I am trying to send jwt=..., however the process fails as described above.

Did you attach the server logs?

yes

Did you attach a network dump?

no
