  • 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 converting JPG slideshow to MKV

    17 décembre 2018, par phol

    I am trying to convert a set of jpg files to a slideshow with varying durations using ffconcat

    output.txt contents :

    ffconcat version 1.0
    file slide_0001.jpg
    duration 0.163
    file slide_0002.jpg
    duration 0.533
    file slide_0003.jpg
    duration 1.067
    file slide_0004.jpg
    duration 0.533
    file slide_0005.jpg
    etc.

    FFmpeg command :

    ffmpeg -i output.txt output.mkv

    I also tried :

    ffmpeg -i output.txt -c:v copy output.mkv

    However, when converting, the colours of the images become skewed.
    White becomes pink / purple and dark green becomes light green.
    The same happens when choosing different codecs and containers.
    Is there a way to solve this ?

    EDIT :
    I performed the same conversion again. I attached the log output as requested.
    However, in the meantime I have figured out that converting without ffconcat duration and then altering timecodes with mp4fpsmod is more efficient in terms of storage (3 vs 40 MB) and gives less issues in different players. The result is nonetheless the same : colours are still wrong, both on my workstation (Ubuntu 18.04) and laptop (macOS Mojave).

    I tried to alter things with pix_fmt and -vf format as can be seen in the second log output. This did not solve the problem.

    Background info :
    The input jpg files are from a lecture recording made with MediaSite, which has both a video stream for the room as well as this slideshow stream for the slides.

    Example of input :

  • ffmpeg converting JPG slideshow to H264

    22 décembre 2018, par phol

    I am trying to convert a set of jpg files to a slideshow with varying durations using ffconcat

    output.txt contents :

    ffconcat version 1.0
    file slide_0001.jpg
    duration 0.163
    file slide_0002.jpg
    duration 0.533
    file slide_0003.jpg
    duration 1.067
    file slide_0004.jpg
    duration 0.533
    file slide_0005.jpg
    etc.

    FFmpeg command :

    ffmpeg -i output.txt output.mkv

    I also tried :

    ffmpeg -i output.txt -c:v copy output.mkv

    However, when converting, the colours of the images become skewed.
    White becomes pink / purple and dark green becomes light green.
    The same happens when choosing different codecs and containers.
    Is there a way to solve this ?

    EDIT :
    I performed the same conversion again. I attached the log output as requested.
    However, in the meantime I have figured out that converting without ffconcat duration and then altering timecodes with mp4fpsmod is more efficient in terms of storage (3 vs 40 MB) and gives less issues in different players. The result is nonetheless the same : colours are still wrong, both on my workstation (Ubuntu 18.04) and laptop (macOS Mojave).

    I tried to alter things with pix_fmt and -vf format as can be seen in the second log output. This did not solve the problem.

    Background info :
    The input jpg files are from a lecture recording made with MediaSite, which has both a video stream for the room as well as this slideshow stream for the slides.

  • EXC_BAD_ACCESS at avformat_find_stream_info in FFMPEG

    27 décembre 2018, par Mubin Mall

    I achieved IP Camera streaming using ffmpeg with the help of this library : https://github.com/kolyvan/kxmovie also I am recording IPCamera streaming coming and same is done using ffmpeg.

    Now I am facing one issue as soon as I add R5ProStreaming.framework in project and run application in real device application is getting crashed at if (avformat_find_stream_info(formatCtx, NULL) < 0) here.
    And when I remove that framework and move it to trash and run again then all working fine.

    More over I contacted Red5Pro team and asked them regarding that along with video demo. They replied me like this

    What’s most likely happening is that the version of FFMPEG that’s being loaded by that project is incompatible with the customized version of it that’s embedded in our SDK, and some duplicate definition error is causing the wrong version to be loaded. It could also be any number of conflicts between one of the libraries in that project with the SDK, or one of the support libraries that the sdk requires ( I have to assume that since it compiled, that you did add the libraries listed in step four here : https://www.red5pro.com/docs/streaming/ios.html#project-setup ) and if that’s the case, I don’t know of a good way to correct the issue as chasing down individual third-party libraries that raise incompatibilities with our SDKs to correct them is beyond the reach of our team.

    Can anybody have idea where to look ?

    Thanks
