Multicast video stream from Dahua IP surveillance camera - ffmpeg etc [closed]
23 mai, par Jaroslav MazurakI have a Dahua IP surveillance camera and want to get the video via a multicast stream.


In the camera settings, I enabled Multicast streaming, IP 239.240.1.2, and port 40000 (the default). The RTSP port is 554 (the default).


Neither VLC 3.0.21 nor ffmpeg 7.1.1 work when I try to use multicast. Both of them work when I use a unicast. OS is Windows 11 x64. Both applications are allowed in the Windows firewall (any protocol, all networks ; same result if the firewall is disabled completely). I have Wireshark installed, and I see that when a client requests the stream via RTSP, the multicast traffic from the camera is present ; ffmpeg determines the stream but doesn't capture any video, and the output file is empty (it contains only the header and no video). When I use unicast, the correct output video file is saved.


I have no idea what I'm doing wrong, and why ffmpeg (and VLC) doesn't capture anything in the multicast mode.


Here are the ffmpeg logs for multicast and unicast modes.
