  • 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 (...)

  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Compile OpenCV3 with Cuda7.5 ffmpeg (latest) issue OpenSUSE 13.2

    23 janvier 2016, par Ingeborg

    I am using an OpenSUSE 13.2-X86-64 and a Geforce 940M GPU. I want to work with it on the Qt5 IDE.
    For this purpose, i have installed my GPU Driver with the Cuda7.5 toolkit rpm from the cudazone. Everything is nearly fine.
    It detects everything I have made and executed a couple of the cuda samples.

    As next step, i have installed the current FFmpeg version with nvenc and other libraries like Xvid and many of
    the other usefull stuff which would be to much to list it here. After that i have downloaded the current
    OpenCV-3.0.0 source code and ran cmake-gui where i have added cuda, ffmpeg, Qt5 etc and maked it.

    On different points of the make session (make -j4) i get this kind of mistake from my console (The list of the Multiple definition
    error is much longer). This is the first one.

  • ffmpeg conversion .dav to any video files

  • Why JPEG image looks different in two videos ?

    28 septembre 2015, par user606521

    I have two frames :

    f1.jpg
    f1.jpg
    f2.jpg
    f2.jpg

    And I am creating two videos :

    ./ffmpeg -i ./f%d.jpg -r 30 -y m1.mp4 # both frames 1 and 2
    ./ffmpeg -i ./f2.jpg -r 30 -y m2.mp4 # only frame 2

    For some reason frame 2 looks different in these two videos

    Frame 2 from m1.mp4 :

    $ ./ffmpeg -i m1.mp4 out1_%d.jpg

    f2_out.jpg

    It seems that frame 2 looks different when combined with frame 1 in a video. One thing I noticed that when dumping frames from m1.mp4 (two frames combined) there is a warning in ffmpeg output :

    [swscaler @ 0x7f7f9a000600] deprecated pixel format used, make sure you did set range correctly

    Also two frame images have same dimmensions (980x100) and their format seems to be same :

    $ file -b f1.jpg
    JPEG image data, JFIF standard 1.01, comment: "CS=ITU601??"
    $ file -b f2.jpg
    JPEG image data, JFIF standard 1.01

    So why this is happening ? I am struggling with this issue for quite a long time - for some reason some JPEGs somehow are in different "format ?" than others and make mess in videos...


    You can download first two images included in this question and test commands on your own.
