    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" (...)

  • webM files shows green and purple effects on mobile

    11 octobre 2015, par Naveen Gamage

    I have converted several GIFs to webM files using ffmpeg on my Ubuntu 14.04 server.

    Heres the code I used for conversation.

    ffmpeg -i your_gif.gif -c:v libvpx -crf 12 -b:v 500K output.webm

    source https://gist.github.com/ndarville/10010916

    The problem is converted webM files shows perfectly fine on PCs but on my mobile it shows with green and purple shadows.

    I tried changing -crf and -b:v values to their max but nothing happens.

    webM file : http://d1pnsuxwa0it39.cloudfront.net/uploads/comments/webm/4673555.webm

    edit :

    also I can see webM files on some other sites fine. I think this has to do something with the way I convert files.

    edit :

    I have tried another code I found on stackoverflow but still the same.

    ffmpeg -f gif -i infile.gif outfile.mp4

    EDIT :

    If anyone think this has something to do with the way I installed FFMPEG, I followed the steps on FFMPEG official docs.

  • convert videos server side using ffmpeg

    22 janvier 2015, par Edward

    Good evening,

    I am looking for a way to convert any type of video format (avi, mp4, 3gp, ogg, etc..) to .flv, I currently use flowplayer and it only supports flv

    I have installed ffmpeg onto my server just fine, the issue is, when ever I upload any video formatted (for an example an .mp4) file I get the error "could not convert video file"

    How may I fix this issue ?

    what I am trying to accomplish with this, I want to upload videos of any format have ffmpeg convert it to lets say .flv and then have the video played through flowplayer
