  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...

  • ffmpeg -Video live feed

    22 juin 2019, par Rajeev

    I am using AMCREST security camera at my home. My objective is to get a live feed one of IP camera attached to my NVR to a webportal using rtsp ://My environment is Raspberry pi.

    I am able to successfully start the ffserver but conversion is failing when I am trying pass the input video and stream it to video.ffm

    I have tried various combination of parameters in the command but the below one seems to be very close where I got only one error ( av_interleaved_write_frame() : Connection reset by peer)

    $ffmpeg  -thread_queue_size 800  -i "rtsp://home:Home1234@192.168.1.32:554/cam/realmonitor?channel=4&subtype=0" -f lavfi -i aevalsrc=0  http://127.0.0.1:8090/video.ffm

    My expectation is that ffmpeg will start writing data to video.ffm located in /tmp directory so that I can read the data from our browser or vlc media player by just entering the following link
    http://localhost:8090/stream

    ****** Update after 2 hr******

    I made slight change to the command parameter and my out changed as well.What it looks like the temporary video file that got generated in /tmp folder is not getting consumes by video.ffm ( I may be wrong in my analysis)
