  • 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.

  • Why duration of the mp4 file created with ffmpeg from png files is smaller than expected ?

    17 août 2021, par qwark97

    I'm trying to concatenate a bunch of png files into one mp4 file using ffmpeg. I use following command :

    


    ffmpeg -f concat -i concat.txt -f mp4 out.mp4


    


    The "description file" (concat.txt) looks like this :

    


    file screen_001.png
duration 0.14538311958312988
file screen_002.png
duration 0.11382007598876953
file screen_003.png
duration 2.543360710144043
...
file screen_036.png
duration 0.15303301811218262
file screen_037.png
duration 0.160630464553833
file screen_038.png
duration 3.2751874923706055


    


    Given command works, I'm able to create desired mp4 file. The problem is, the duration of the output file is smaller than sum of the duration lines from concat.txt. I expect mp4 file 22.48s long but I get 19.20s long file.

    


    What am I doing wrong ? Maybe I'm not using some flag I should ? Is it even possible to do what I want ? I'm kind a newbie with ffmpeg and video manipulation at all so any help would be appreciated.

    


    Output of the ffmpeg, maybe will be useful :

  • How to make my video in landscape mode using ffmpeg

    6 novembre 2019, par Aarwil

    I have four video chats. Somehow I have managed to cut videos into pieces, stored in array then stacked and finally concat the video which is in the youtube link down below. I have used the size in the portrait view is 640*480. But I need to show them in the landscape. Suggest me any ideas.

    At first, I change all the video resolution to 640:480 because each video may have different resolution (probability). So I am setting a fixed resolution.

  • FFMPEG output (Images > Video) is unplayable

    23 décembre 2014, par jgads

    I’m using FFMPEG to make a video slideshow from a group of images on Android. The process completes successfully and the output file is the correct/expected size (or the same as what is reported in FFMPEG’s ’progress’), but the video does not play on any Android video player (MXplayer, VLC, stock). The video players show a perpetual loading circle and never actually launch. MXplayer can see the file and generate a thumbnail but not actually play it. Here is the command :

    ffmpeg -f image2 -re -r 1 -i
    /storage/emulated/0/Pictures/phototest/%d.jpg -vcodec libx264 -f mp4
    -r 24 -preset : ultrafast -an -threads 4 -b 4000k -mbd rd -flags +mv4+aic -trellis 2 -cmp 2 -subcmp 2 -g 300 -y -pix_fmt yuv420p /storage/emulated/0/Pictures/phototest/result1.mp4

    Here’s the output via Android Logcat :

    EDIT : Note that although it appears to run ffmpeg twice here, the output file is the correct size which seems to mean that the file isn’t getting overwritten with a corrupt version, so we can probably just assume there’s a bug with Logcat (right ?)

    EDIT 2 : Trying the same command on the PC works flawlessly. Playing back this video works fine on Android.
