[Live-devel] ProxyServer sending RTSP "options" keep-alive without authentication

[jiehui]

Hi,

We are using the live555ProxyServer to proxy RTSP streams. It works fine 
for most CCTV cameras, but the RTSP Stream keeps getting disconnected 
and ultimately stops entirely for a CCTV camera.

After analyzing network traffic between the proxy server and the CCTV 
camera in question, we realized that the proxy server is sending 
"options" requests to the camera without authentication first, getting 
an "unauthorized" reply, then re-sending with authentication. This 
behavior caused the CCTV camera to invalidate the RTSP session. After re 
setting up session for a few times, the CCTV camera then stopped 
responding to "options" requests.

We've also tried using VLC player (V2.2.1) with the CCTV camera in 
question. The RTSP Stream remains stable. VLC player is sending 
"get-parameter" requests with authentication.


1. Is there any way to make the proxy server send "options" with 
authentication?

2. Is the behavior of the CCTV camera in question correct? (According to 
spec, or widely accepted?)

Best Regards,
Jie Hui
