  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • ffmpeg - drawtext filter producing file with no streams

    24 juillet 2022, par yarrichar

    I am trying to get ffmpeg's drawtext filter working in an AWS lambda. Other operations like concatenating and trimming files works. But drawtext fails for some reason. I run the exact same command on my local machine and it runs fine.

    


    The output is below. The first line shows the parameters passed to ffmpeg.
You can see at the end of the following output that it's only processing 3 frames before exiting.

    


    Any help would be greatly appreciated.

  • get specific metadata with ffprobe

    1er mai, par mikem

    I'm having a terrible time getting one single line of metadata from ffprobe.

    


    I'm running this command :

    


    


    ffprobe -show_entries 'stream_tags :
format_tags=com.apple.quicktime.creationdate' -loglevel error
IMG_9931.MOV

    


    


    And I get this output

    


    


    [STREAM]

    But the only thing I want returned is

    


    


    com.apple.quicktime.creationdate=2022-05-14T16:24:55-0400

    


    


    I've searched and searched but I can't find any examples of pulling a single specific value of metadata.

    


    In actuality, I really just want the value of com.apple.quicktime.creationdate... ie "2022-05-14T16:24:55-0400"

    


    I know I can grep and awk my way through it, but it seems like there should be a way to do it with ffprobe alone given all of the options it has. I just can't figure out how.

    


    How can I do this ? Any help would be appreciated.

    


  • ffmpeg convert from H.264 (High 4:2:2 Profile) MOV to H.264 (Baseline Profile) MP4

    26 juillet 2022, par froniq

    How can I convert a video (MOV) from H.264 (High 4:2:2 Profile) to H.264 (Baseline Profile) MP4 using ffmpeg ?
I would run that mp4 video on android mobile in a VideoView to support as many mobile types as possible.

    


    I can't do that with this command : ffmpeg -i o1.mov -c:v libx264 -profile:v baseline -c:a aac -ar 44100 -ac 2 -b:a 128k out.mp4.

    


    That'd return an error :
