rtspsrc Content-Base regression?
In GStreamer 1.16.3, when receiving a Content-Base header in the response of a DESCRIBE call, the URI for the SETUP command uses this Content-Base. In GStreamer 1.20.1, it appears that the Content-Base is ignored?
In both examples the location is rtsp://relay.something.com:443/<REDACTED/ipcam_h264.sdp?token=<MYTOKEN>
1.16.3 example:

rtspsrc gstrtspsrc.c:6524:gst_rtsp_src_receive_response:<rtspsrc>[00m error: Could not receive message. (Parse error)In 1.20.1 if I change the URI manually to be rtsp://<REDACTED>/stream1-2/track1, the setup succeeds.
The reliance on this may be an issue with the server but what is the intent with the code? Or is this because the SDP specifies control as * so then the base URL ends up being used? The relevant code blocks in rtspsrc.c don't seem to have changed much between 1.16.3 and 1.20.1 at first glance.
I'm mainly looking for answers to:
- Which is the correct construction of the URI for SETUP? (Is this a regression in 1.20.1?)
- If 1.20.1's is correct, then what would be a good workaround for this? If content_base is correctly being parsed out from the headers but is just not being used, it's not externally accessible I think? Maybe modifying the SDP control:* part?
Thanks in advance!
