  • 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" (...)

    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 ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

    yadif : restore speed of the C filtering code

    Always use the special filter for the first and last 3 columns (only).
    

    Changes made in 64ed397 slowed the filter to just under 3/4 of what it
    
was.  This commit restores the speed while maintaining identical output.

  • ffmpeg how to ignore (skip) errors when concatenate and speed up multiple video files

    3 avril 2016, par user1767834

    I’m trying to concatenate many files from my car DVR but some time ffmpeg fails with "Invalid argument" error.
    My list of files in cf.txt looks like :

    file '2016_0403_170004_098.MOV'
    
file '2016_0403_170459_099.MOV'
    
file '2016_0403_170630_100.MOV'
    
...

    And I run ffmpeg using next command :

    ffmpeg -f concat -i cf.txt -qscale:v 0 -filter:v "setpts=0.05*PTS" -an e:\MOVIE\all.mov

    After some outputs ffmpeg crushes with message :

    Output #0, mov, to 'e:\MOVIE\all.mov':

    See line :

    cf.txt : Invalid argument

    So, I want to ignore this error (and any other if possible) and continue to process the files.
    Is it possible ?
