  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • Gestion des droits de création et d’édition des objets

    8 février 2011, par

    Par défaut, beaucoup de fonctionnalités sont limitées aux administrateurs mais restent configurables indépendamment pour modifier leur statut minimal d’utilisation notamment : la rédaction de contenus sur le site modifiables dans la gestion des templates de formulaires ; l’ajout de notes aux articles ; l’ajout de légendes et d’annotations sur les images ;

  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • FFmpeg : avconv and ffserver - connection reset by peer

    5 mars 2016, par einsA

    I’m trying to stream a video via ffserver. My dev environment is a Raspberry Pi 2.

    I’m getting an av_interleaved_write_frame(): Connection reset by peer with the following approach :

    pi@raspberrypi:/opt/livefeed $ avconv -f mjpeg -i movie.mjpg -r 20 -b 2000k -vcodec libx264 -preset ultrafast -f flv -metadata streamName="mjpeg_to_flv" -metadata title="converting mjpeg to flv via avconv" http://localhost:8090/feed1.ffm

    So why does it works step by step via the movie.flv file and not directly ?

    What is the difference between

    • avconv -f mjpeg -i movie.mjpg -r 20 -b 2000k -vcodec libx264 -preset ultrafast -f flv -metadata streamName="mjpeg_to_flv" -metadata title="converting mjpeg to flv via avconv" movie.flv
      followed by
      ffmpeg -stream_loop -1 -i movie.flv http://localhost:8090/feed1.ffm and

    • avconv -f mjpeg -i movie.mjpg -r 20 -b 2000k -vcodec libx264 -preset ultrafast -f flv -metadata streamName="mjpeg_to_flv" -metadata title="converting mjpeg to flv via avconv" http://localhost:8090/feed1.ffm ? Why ends this command with a av_interleaved_write_frame(): Connection reset by peer ?

  • Android recording video with overlay view

  • H264 Encoding - Could not play video using VLC Player

    31 mars 2016, par bot1131357

    I am have trouble encoding an H264 video correctly using FFmpeg libav. I could not play the encoded video in VLC media player, and although I could play the video on MPC-HC the time shows 00:00/00:00. Clearly I’m missing something.

    The Media info from MPC-HC shows this :

    General

    I noticed something odd in the above info :
    - The frame rate is 20.833 fps, instead of the specified 10 fps.
    - Duration of 2s 400ms did not seem right either, since the video played for more than 4s.

    Also, (AVFrame* picture)->pict_type is always set to AV_PICTURE_TYPE_NONE. I don’t think this is normal.

    The library that I’m using is ffmpeg-20160219-git-98a0053-win32-dev. I would really really appreciate if you could help me out of this confusion.
