    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" (...)

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...

  • ffmpeg drops all frames after 6 seconds

    25 juin 2014, par user2099107

    New to FFMPEG, I’m trying to create a video from a set of png.

    I have 96 png and I’m looking to 4 FPS (24 seconds of video)

    I use the following command :

    /Applications/ffmpeg -y -r 4 -pattern_type glob -i './images/*.png' -c:v libx264 -pix_fmt yuv420p out.mp4

    my out.mp4 always commes out as roughly 6 seconds with 24 frames, the last 70 frames being dropped.

    here is the full output :
