  • 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" (...)

  • Jerky Video from Jpgs encoded with ffmpeg [closed]

    16 février 2012, par Glstunna

    I have a bunch of jpg snapshots taken from a 3d program at perfect time frames.
    But when I have the videos compiled/encoded into a video by ffmpeg, I notice an annoying jerkiness. The jerkiness is not that pronounced, but enough to be annoying, especially during slow camera pans.

    This is what I use :

    "ffmpeg-lgpl.exe" -y  -r 29.97 -i "C:\vidsnaps\vid_%d.jpg" -b 8000k "C:\Users\peki.ICE\Documents\macbattle.mpg"

    I chose mpg (mpeg1video) because that is the format readily available in all end-user systems like XP without downloading extra codecs. The video images are guaranteed to match that framerate 29.97 as the camera in the 3d program pretty much waits for each frame to be dumped to file before moving to the next one.

    What other fancy ffmpeg flags do I have to set for this thing to stop being jerky.

    EDIT : see video example here and notice the light jerk/stuttering.

  • Cutting a video to the last 10 seconds

    1er avril 2014, par ShiftedDesign

    So I am looking for a way to cut a video file to the last 10 seconds of the file. Normally I would use FFMPEG or mencoder but the situation is that the file to be cut is going to be a different size every time it's cut. So I found some stuff for a general duration using ffmpeg but the problem is I would need the duration to be in seconds instead of 00:00:00 so then I could just use the var-10 for the -ss.

    I don't know if I explained that well enough but in short :

    Different length video every time it is ran, only need the last 10 seconds in a new file.
    Need something light on resources but still fast.

    Thanks in advance for anyone who answers !
