Hi Ross,

I believe this change causes the media clients to only be able to
receive the first track of a multi-track file, such as an mkv with
video and audio. The answer to SETUP of the second track and others is
a "400 Bad Request".

Please find a test file here:

This may be the same issue as the one reported by Thilina Jayanath.

Regards.

P.S: the entire conversation between client and server:
