Describe the issue

When using a hardware encoder such as the blackmagic web presenter HD is seems to cause mediamtx to reject the stream due to some extra streamid parameters being sent by the encoder. Note these can't be switched off/disabled and seem to the default behavior.

This is an example streamid being sent by the encoder:

#!::bmd_uuid=0e1df79f-77e6-465c-b099-29a616e964f7,bmd_name=rdt-wp-003,r=test3,m=publish

A temp work around is to comment out the return, this fixes the issue.
Perhaps it should warn that it is ignoring none useful streamid parameters?

streamid.go

			default:
				// return fmt.Errorf("unsupported key '%s'", key)
			}

Describe how to replicate the issue

1. start the server
2. publish a srt stream with the blackmagic web hd encoder.
3. see the error in the console and the stream is rejected.

Did you attach the server logs?
