Hi, I'm working on implementing multicast streaming using the Live555 RTSP server (v4l2rtspserver). My current understanding is that when a client sends a SETUP request for a multicast stream, the server should not initiate a new session each time. Instead, it should reuse the existing multicast session. However, in my setup, the server appears to create multiple sessions for the same multicast stream, which is unexpected. Below is an excerpt from the server log: ________________________________ 🧾 Server Command: /tmp/v4l2rtspserver /dev/video3 -fHEVC -W1920 -H1080 -P5005 -F60 -M232.22.5.67 -mroutecam_m
Log [NOTICE] Version: 0.3.11-23-gde3c395-dirty live555 version: 2025.01.17 [NOTICE] Create V4L2 Source... /dev/video3 [NOTICE] RTP address 232.22.5.67:20000 [NOTICE] RTCP address 232.22.5.67:20001 [NOTICE] RTP format: video/H265 [NOTICE] Play this stream using the URL "rtsp://192.168.1.10:5005/routecam_m" handleCmd_SETUP: SETUP rtsp://192.168.1.10:5005/routecam_m/track1 RTSP/1.0 Transport: RTP/AVP;multicast ... handleCmd_SETUP: SETUP rtsp://192.168.1.10:5005/routecam_m/track1 RTSP/1.0 Transport: RTP/AVP;multicast ... My Question Why is the server initiating a new session for each SETUP, even though the transport is multicast? Shouldn’t Live555 be reusing the same multicast subsession for all clients? Any guidance or configuration pointers would be greatly appreciated.
