  • 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" (...)

  • How to write the ffmpeg complie configure for merge wav and single image to mp4 ?

    8 mai 2016, par 纯洁的坏蛋

    I found the commond line :

    ffmpeg -loop 1 -i img.jpg -i audio.wav -c:v libx264 -c:a aac -strict experimental -b:a 192k -shortest out.mp4

    and it work nice.

    but how to write the configure file ?

    I have the eg :

        #!/bin/bash
    
pushd `dirname $0`
    
. settings.sh
    

    
if [[ $DEBUG == 1 ]]; then
    
  echo "DEBUG = 1"
    
  DEBUG_FLAG="--disable-stripping"
    
fi
    

    
# I haven't found a reliable way to install/uninstall a patch from a Makefile,
    
# so just always try to apply it, and ignore it if it fails. Works fine unless
    
# the files being patched have changed, in which cause a partial application
    
# could happen unnoticed.

    How to make the ffmpeg simple ?

  • Using FFmpeg to encode 2pass mp4

    30 juin 2016, par Erin.Yang

    I am trying to use FFmpeg to encode my 4K mp4 file to a 2pass 265 mp4 file for the purposes of testing. I am new to video compression and hope I’m making a simple mistake that someone can correct.

    All infos in command line as below :

    C:\Ying\FF>C:\Ying\FF\ffmpeg.exe -y -i C:\Ying\FF\Xman-4K_50sec_3840x2160.mp4 -preset veryslow -x265-params pass=1 -vcodec hevc -b:v 15M -acodec libvo
