  • 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 (...)

    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.

  • Combine 2 .FLV videos

    4 décembre 2015, par Rune

    For the last 4 hours I’ve been trying to combine 2 .flv files into one using ffmpeg (or well, just C# in general).

    Here’s what I got so far :
    I’ve converted both the videos to .mp4 videos :

    "-i " + videoFileLocation + " -c copy -copyts " + newConvertedFileLocation

    I have then combined the two .mp4 files into a single one using :
    (txtPath is the text file with the two mp4 file locations)

    "-f concat -i " + txtPath + " -c copy " + saveLocation

    This ends up with an mp4 file which contains the combination of both the videos BUT with the following fault :

    The length of the first video is 0:05

    The length of the second video is 6:11

    However the length of the combined video is for some reason 07:51 - thus the video runs at a slower pace than it should.

    Furthermore the audio is async with the video.

    What am I doing wrong here ?

    I haven’t used ffmpeg before and I just wanna get this working.

    Any help is greatly appreciated !

    As requested here is the output from running ’ffmpeg -i input1.flv -i input2.flv’ :
