La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans 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, parTo 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 - convert MP4 to Panasonic Lumix playable MJPEG [closed]
21 août 2024, par Maro NattsI'm new to ffmpeg and ffprobe, I started using it to convert videos to show on 3DS and DSi for an art project.


Now I want to show my own videos on a Panasonic LUMIX digicam (DMC-FT2)(JPN), but have had trouble getting the device to play the video.


The digi takes videos in AVCHD Lite and Motion JPEG.


I've tried online converting mp4 to the respective formats + changing file name, but the device only recognises that it's there — refuses to/can't play it.


I also tried using this code to convert to MJPEG :

ffmpeg -i input.mp4 -c:v mjpeg -q:v 2 -an output.mjpeg

But no luck ! Changed the filename to match the others, the camera recognised the file is there, but can't play it.


So I used this code to get the information of a MJPEG video taken on the digi :

/opt/ffmpeg/ffprobe file.mp4 -show_streams -select_streams v -print_format json

and got the following, is it possible to convert my own video (mp4) to these settings ? So that it can play on the device ? If so how ?


Thanks !

Google Analytics Sampling : Why It Matters and How to Avoid It

Facing issues with adding text over a video as watermark using ffmpeg in Laravel
18 septembre 2024, par KelashI am facing issues with adding text over a video as a watermark using pbmedia/laravel-ffmpeg.


Where am I going wrong ?


Code :


$format = new X264();
$format->setAudioCodec('aac');
$format->setVideoCodec('libx264');
$format->setKiloBitrate(0);

$localPath = '/' . $this->video->id . '.mp4';

$ffmpeg = FFMpeg::fromDisk("public")
 ->open($localPath)
 ->addFilter(function ($filters) {
 $filters->custom("drawtext=fontfile=S:/Freelancer/version58trials/version58trials/public/webfonts/arial.TTF:text='Stack Overflow':fontcolor=white:fontsize=24");
 })
 ->export()
 ->toDisk('public')
 ->inFormat($format)
 ->save("watermark_video_added.mp4");


And this is error I am getting :

What I tried, is manipulating that filter function but I couldn't make it.


For your knowledge,the video paths and font path is correct the only issue is with ffmpeg adding watermark text logic.
