  • Multicast video stream from Dahua IP surveillance camera - ffmpeg etc [closed]

    23 mai, par Jaroslav Mazurak

    I 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.

    9 octobre 2020

    Plusieurs remarques :

    - tu montres un raisonnement avec des personnes ne connaissant pas l’interface. Ok, mais une fois que tu la connais tu sais que le bouton commence l’action d’ajouter une autrice, ou de changer la date. Le fait que ça commence l’action, et non la termine, justement, me semble une indication que c’est n’est pas forcément un .primary à mettre... En général la couleur dominante sert dans les formulaires / boutons à valider / sauvegarder / traiter l’action. Je ne trouve pas que ça soit le plus pertinent ici : ces boutons n’engagent à rien, l’action n’est pas dangereuse. Il faut qu’on sache qu’ils existent et soient visibles, je te l’accorde. Mais je reste sceptique sur l’usage de .primary ici dessus. (encore une fois, ça me va aussi, c’est pas non plus la fin du monde, mais ça fait beaucoup de boutons bien visibles partout dans cette interface, et je vois pas l’utilité de ça : c’est pas mieux pour l’utilisateur·trice si y a un trop plein de boutons bien visibles partout...).
    - pourquoi "retirer ce X" et "ajouter ce X" seraient différent ?
    - et « non, changer la date est moins important et beaucoup plus rare qu’ajouter un auteur, un mot, un point GIS » : je ne suis pas trop d’accord. C’est aussi ton point de vue dans ton contexte et habitudes, mais pour ma part ça m’arrive aussi plus fréquemment de changer des dates, plus que des auteurs ! Mais pour moi, encore une fois, l’important est plus d’être cohérent dans l’ensemble, et justement ne pas faire (trop) de cas particuliers pour ceci ou cela.
