  • 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.

    Pour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.
    Il est important, après avoir installé apache2, mysql et php5, d’installer d’autres logiciels nécessaires dont les installations sont décrites dans les liens afférants. Un ensemble de librairies multimedias (x264, libtheora, libvpx) utilisées pour l’encodage et le décodage des vidéos et sons afin de supporter le plus grand nombre de fichiers possibles.

  • ffmpeg : Conversion to mkv with compatibility with Samsung BluRay

    23 mai 2020, par Yehor

    I have several videos (FullHD resolution) which I want to convert to mkv format and play on my Samsung BluRay Player (model BD-J5900).
Based on User Manual (http://media.datatail.com/docs/manual/252846_en.pdf , page 6) it supports mkv playing if codecs are :

    



      

    • Video : H.264 BP/MP/HP

      • 


    • Audio : MP3

      • 


    



    Thus, based on https://ffmpeg.org/ffmpeg.html the command to convert it into proper format is :

    



    ffmpeg -i input.avi -f matroska -vcodec libx264 -acodec mp3 output.mkv


    



    It converts, but file is not playable on player. It say "Video format is not supported".

    



    After checking info here : https://trac.ffmpeg.org/wiki/Encode/H.264 - I thought it may require some compatibility and change the command to :

    



    ffmpeg -i input.avi -f matroska -vcodec libx264 -profile:v baseline -level 3.0 -acodec mp3 output.mkv


    



    But it also didn't help - player demonstrates the same error.

    



    How to fix that ?
Thanks !

    



    Updated : 
Also tested following options

    



     ffmpeg -i input.file -f matroska -vcodec libx264 -preset veryslow -x264-params bluray_compat=1 -acodec mp3 output.mkv
 ffmpeg -i input.file -f matroska -vcodec libx264 -preset veryslow -profile:v high -level 4.2 -x264-params bluray_compat=1 -acodec mp3 output.mkv
 ffmpeg -i input.file -f matroska -vcodec libx264 -preset veryslow -profile:v baseline -level 3.0 -x264-params bluray_compat=1 -acodec mp3 output.mkv
 ffmpeg -i input.file -vcodec libx264 -vf format=yuv420p -preset veryslow -acodec mp3 output.mkv


    



    Also not supported.

  • ffmpeg : Convertion to mkv with compatibility with Samsung BluRay

    25 octobre 2018, par Yehor

    I have several videos (FullHD resolution) which I want to convert to mkv format and play on my Samsung BluRay Player (model BD-J5900).
    Based on User Manual (http://media.datatail.com/docs/manual/252846_en.pdf , page 6) it supports mkv playing if codecs are :

    • Video : H.264 BP/MP/HP
    • Audio : MP3

    Thus, based on https://ffmpeg.org/ffmpeg.html the command to convert it into proper format is :

    ffmpeg -i input.avi -f matroska -vcodec libx264 -acodec mp3 output.mkv

    It converts, but file is not playable on player. It say "Video format is not supported".

    After checking info here : https://trac.ffmpeg.org/wiki/Encode/H.264 - I thought it may require some compatibility and change the command to :

    ffmpeg -i input.avi -f matroska -vcodec libx264 -profile:v baseline -level 3.0 -acodec mp3 output.mkv

    But it also didn’t help - player demonstrates the same error.

    How to fix that ?
    Thanks !

    Updated :
    Also tested following options

     ffmpeg -i input.file -f matroska -vcodec libx264 -preset veryslow -x264-params bluray_compat=1 -acodec mp3 output.mkv
    
 ffmpeg -i input.file -f matroska -vcodec libx264 -preset veryslow -profile:v high -level 4.2 -x264-params bluray_compat=1 -acodec mp3 output.mkv

  • Video and audio stretch calculations in ffmpeg

    30 janvier 2017, par garrettlynch

    I’m doing some extreme slow motion in ffmpeg on a video, both video and audio track, but can’t quite get my calculations correct.

    The input video is 00:06:41:00 at 24fps (9624 frames).
    I need the output video to be 34:00:00:00 at 24fps (2937600 frames).

    I tried these for the video and audio :

    setpts=305.237*PTS
    

    
atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.807668329177057

    However the video overshoots by 00:01:19:08 and the audio I’m unsure, on one player it stops somewhere around 8 hours but on another it just continues. What are the correct formulas ?

    Also on VLC the video has grey frames between video frames - do I need to interpolate to have continuous video frames ?
