  • 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) (...)

  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • 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 (...)

  • Podcast Producer 2 REST api

    11 septembre 2009

    I’ve been working on documenting the REST api that PCP2 uses for client server communication as part of a new project. I thought it might be useful to other folks. Consider this a work in progress - I’ve only documented the workflow for doing a multisource recording so far. Follow the job for the info.

    Each section gives a sample command and a sample response.

    All pages are behind basic HTTP auth.

    General sequence of events

    * get workflow list
    * get cameras
    * request status for camera (including thumbnail)
    * start cameras
    * create recording enclosure
    * stop cameras, provide submission_UUID returned by above step, include title

  • Pass camera input to ffmpeg

    30 mai 2017, par Sachin Sonone

    I am trying to develop an delphi app which will show a preview of the camera in the delphi form and then send the frames of video as images to the ffmpeg in the stdin of ffmpeg. ffmpeg then broadcast the video to wowza server over rtmp. but fmpeg gives an error ’pipe:0 Bad file descriptor’

       FFMPEG command:
       ffmpeg -f image2pipe -i pipe:0  -c:v libx264 -y -report -f flv wowza_url

    I followed this https://msdn.microsoft.com/en-us/library/ms682499(VS.85).aspx article to build the parent app which will open ffmpeg as a child and use FFmpeg’s stdin to pass input

      // Create a pipe for the child process's STDOUT.
    Createpipe(STDOut_ReadPipe, STDOut_WritePipe, @Security,0);

     // Ensure the read handle to the pipe for STDOUT is not inherited.
    SetHandleInformation(STDOut_ReadPipe,HANDLE_FLAG_INHERIT,0);

    // Create a pipe for the child process's STDIN.

    if (  CreatePipe(STDIn_ReadPipe , STDIn_WritePipe, @Security, 0) = true) then


    // Ensure the write handle to the pipe for STDIN is not inherited.

    SetHandleInformation(STDIn_WritePipe, HANDLE_FLAG_INHERIT, 0)  ;

    This the code to start ffmpeg process

    FillChar(StartupInfo,Sizeof(StartupInfo),0);
    StartupInfo.cb := Sizeof(StartupInfo);
    StartupInfo.dwFlags := STARTF_USESTDHANDLES;


    StartupInfo.wShowWindow := 1;
    S := args;
    UniqueString(S);

    StartupInfo.hStdError := STDOut_WritePipe;
    StartupInfo.hStdOutput := STDOut_WritePipe;
    StartupInfo.hStdInput := STDIn_ReadPipe;

    but as soon as program start ffmpeg exits with the error.

    This is the full console log of the ffmpeg

    ffmpeg started on 2017-05-30 at 18:45:36

  • FFMPEG and MSA1 Codec Issues when Converting WMV to MP4 Video

    30 décembre 2023, par user136819

    I have a WMV video file (around 60 MB size, 01:23:00 length) and I'm running a Windows Server 2016 64-bit machine for testing.
    &#xA;As far as I know, this video file was recorded using Microsoft Live Meeting 2007 back in April 2010 and there is also an associated audio file (which I'm able to play).

    &#xA;

    I tried to play the video file on my machine using VLC player (latest update), however, I always see this weird MSA1 codec error :

    &#xA;

    enter image description here

    &#xA;

    So I tried to resolve this problem by downloading and installing the Combined-Community-Codec-Pack-64bit-2015-10-18, and using its MPC-HC 64-bit player to play the video...&#xA;I still couldn't get it to play ! Here are the logs shown by the MPC player :

    &#xA;

    enter image description here

    Since that didn't work, I tried installing the Microsoft MPEG-4 V1/2/3 VKI Codec for ASF files and still couldn't get the players to play the video and saw the same errors as above !

    &#xA;

    As a final attempt, I tried to convert this video to MP4 format using FFMPEG (version from 2020). Even this failed. Here are the logs :

    I wish to know, is there any other way I can convert this video to a more modern format so that I can play it on a modern machine and modern video player ?
    &#xA;What other codecs am I missing here ? (if so, where can I get them ?)
    &#xA;FYI, as mentioned earlier at the top, I'm only able to play the associated audio file...

    &#xA;

    I'm fairly new to all this stuff, so any help is appreciated.

    &#xA;

    Thanks in advance ! :)
