  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Monitoring de fermes de MediaSPIP (et de SPIP tant qu’à faire)

    31 mai 2013, par

    Lorsque l’on gère plusieurs (voir plusieurs dizaines) de MediaSPIP sur la même installation, il peut être très pratique d’obtenir d’un coup d’oeil certaines informations.
    Cet article a pour but de documenter les scripts de monitoring Munin développés avec l’aide d’Infini.
    Ces scripts sont installés automatiquement par le script d’installation automatique si une installation de munin est détectée.
    Description des scripts
    Trois scripts Munin ont été développés :
    1. mediaspip_medias
    Un script de (...)

  • rtmp can be played by ffplay, but video.js not

    I just run

    It can be played with ffplay, but in video.js, it shows FLASH : rtmpconnectfailure ; I googled the message Frame num change from but didn’t get useful information, so how can I debug this and find a solution ?
    Any help would be appreciated, thank you !

  • Is it possible to encode one yuv file to 3 h.264 files with different bitrates with one command ?

    24 juillet 2012, par Richard Knop

    I have a YUV file. I need to encode it to H.264 but using three different bitrates. Is it possible to do it with one command so the yuv file does not need to be processed muttiple times ?

    Here's what I do right now :

    x264 -B 600 -o /path/to/output_first.264 /path/to/input.yuv
    
x264 -B 800 -o /path/to/output_second.264 /path/to/input.yuv
    
x264 -B 1000 -o /path/to/output_second.264 /path/to/input.yuv

    Is it possible to do it in one command to make it faster ? YUV file can be quite big so I don't want to extract it three times in a row. And all three encoding processes use the same input YUV file so I guess it should be possible.
