After upgrading, I can no longer open a stream to my security camera (rtsp://frontcam2/). This worked fine before the upgrade. I can open mpeg files and audio and video work fine on those.
I turned on debug messages, and I got
main debug: net: connecting to frontcam2 port 554
main debug: connection succeeded (socket = 17)
access_realrtsp warning: Cseq mismatch, got 1, assumed 0
access_realrtsp debug: rtsp connected
access_realrtsp warning: only real/helix rtsp servers supported for now
