  • 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" (...)

  • FFMPEG compiled binaries don't run using MinGW

    9 juin 2015, par Paul Knopf

    I am trying to build windows executables/dlls for Windows XP, and they are not working. They are the correct architecture. They run fine on my Windows 8 device machine.

    I used dependency walker to find missing DLLs, and all were present.

    Here are the compiled executables I am trying to run.

    I ran the windows build script for ffmpeg.

    Here is a dumpbin /headers ffmpeg.exe

  • command line audio equalizer ffmpeg sox

    5 novembre 2016, par user1320370

    I need to add equalizer effect on some flac files :

    f=4043, 1.65q, g=9.5; f=7024, 1.09q, g=3.7; f=9254, 0.94q, g=-2.5

    I was tried ffmpeg :

    ffmpeg -i solovoce_compress.flac -af equalizer=f=4043:width_type=q:w=1.65:g=9.5, equalizer=f=7024:width_type=q:w=1.09:g=3.7,equalizer=f=9254:width_type=q:w=0.94:g=-2.5 solovoce_equalizzato.flac

    but the result is much different then what I expect, this values was calculated by izotope ozone (professional audio editor software) and tested.

    I used the equivalent with sox and the result is some.

    A this point I like to try ffmpeg ’anequalizer’ filter that show the graph so I can ’see’ the difference, but I the documentation to show the graph is not clear and I was not found nothing about on web.

    Someone can please send me an example of ’anequalizer’ with plot enabled ?
