  • Changer son thème graphique

    22 février 2011, par

    Le thème graphique ne touche pas à la disposition à proprement dite des éléments dans la page. Il ne fait que modifier l’apparence des éléments.
    Le placement peut être modifié effectivement, mais cette modification n’est que visuelle et non pas au niveau de la représentation sémantique de la page.

  • Initialisation de MediaSPIP (préconfiguration)

    20 février 2010, par

    Lors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.
    Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.
    Ce plugin sert à préconfigurer de manière correcte chaque instance de MediaSPIP. Il doit donc être placé dans le dossier plugins-dist/ du site ou de la ferme pour être installé par défaut avant de pouvoir utiliser le site.

  • 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.
