  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • De l’upload à la vidéo finale [version standalone]

    31 janvier 2010, par

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
    Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

  • bash script to install / update ffmpeg static builds

    1er mars 2017, par Joakim

    Hi I’m trying to make my first "real" bash script to do some real work than can be executed both manually and through cron jobs.

    The script should download and install the ffmpeg-static-build from https://johnvansickle.com/ffmpeg

    Here is what I’ve got so far :

    #!/bin/bash
    
# Still to come, see if the script runs with root privileges else exit
    
#Download FFMPEG static daily build and it's md5
    
cd ~
    
wget https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz | tar -xf
    
#wget https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz.md5
    
curl -L https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz.md5 | tar -xf | tee -a https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz | cut -d\  -f1 | md5sum > md5sum.txt
    

    

    
#Chech the md5 is currect
    
#md5sum -c MD5SUMS
    
file1="md5sum.txt"
    
file2="ffmpeg-git-64bit-static.tar.xz.md5"
    

    
if ! cmp --silent "$file1" "$file2"; then
    
    echo "md5sum doesn't match...\n exit" >&2
    
    exit 1
    
fi
    

    

    
#tar -xf ffmpeg-*.tar.xz
    
cp ffmpeg-*-static/ff* /usr/bin/
    
cp ffmpeg-*-static/ff* /usr/local/bin/
    
cp ffmpeg-*-static/qt-faststart /usr/bin/
    
cp ffmpeg-*-static/qt-faststart /usr/local/bin/
    
# Consider change second location to use ln -s
    
# Remove downloads and do some clean up
    

    
rm -fr ffmpeg-*
    

    
#EOF

    As you can see in the script i would like to add the md5sum check but it fails (got the md5sum check part from Compare md5 sums in bash script)

    If i remove the md5sum part the script is working, but right now the script fails at the | tar -xf | part with this code

    As this is my first, I would appreciate any "I’m 4 years old" advices and why

    update

    Have made some changes to the script based on the suggestions in this thread, but my problem is I have no output what so ever at this state :( So I think it’s time to ask for the next clue

    But still having some issues :(

    1. Running this script returns : a blanc shell, but I’ve expected one of the printf statements
    2. When I’m trying to narrow down the problem and going back to basic and trying to run the script with only the "if" part it fails with 44 : Syntax error : "(" unexpected

    3. running the very same "if" part typed directly into the shell/terminal itself it’s all happy !!
      if diff <(md5sum ffmpeg-git-64bit-static.tar.xz) <(curl -s "https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz.md5"); then printf "%s\n" "No new version availeble" >&2; elif ! diff <(md5sum ffmpeg-git-64bit-static.tar.xz) <(curl -s "https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz.md5"); then rm -f ffmpeg-git-64bit-static.tar.xz; curl https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz > ffmpeg-git-64bit-static.tar.xz; printf "%s\n" "Going to install new version" >&2; fi

    4. I’m confused
