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 (...) -
Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

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 on windows 7, encode video in mp4 for HTML 5 video fail
14 avril 2013, par manonthemoonI try to encode my video with FFmpeg, to convert to mp4.
But the video doesn't work on html 5. I don't understand why.I found this command on the web and I tried it :
ffmpeg.exe -i wildlife.wmv -b 1500k -vpre slow -vpre baseline -vcode libx264 \ -g 30 wildlife.mp4
But it fails, and I have this error :
File for preset 'slow' not found
I check the folder "presets" and the preset is on the folder, so I don't understand why it's telling me this error.
I tried with the complete path, it fails too. -
What's the ideal encoding for rendering an immediate video (e.g. preview) while waiting for the high-quality video to render ? [on hold]
20 avril 2018, par allanbreyesI’m working on an application that renders an MLT (OSS non-linear video-editing engine) project on a web server, which uses ffmpeg under the hood. While waiting for the high-quality render to finish (several minutes), I need to make a "best-effort" render in parallel so that users can immediately (i.e. real-time) see the results. What encoding works best for this ?

How to generating waveform from video & show it with video
25 novembre 2016, par SalilWe are using Rails as a backend & AngularJS on Front End side in my App where we need to show Video & audio waveform of that video.
We are using ’wavesurfer.js’ to show the waveform on Front End side & ’node-pcm’ to generate pcm from video file on BackEnd side.
This is working as expected but in some of the videos while creating waveform from pcm data instead of showing small sine waves we get flat line.
Also it takes too much time to show the waveform for every page reload.To overcome this issue we are planning to create waveform image using ffmpeg
ffmpeg -i 'https://s3.amazonaws.com/aadasdsadsadasdas/xyz.mp4' -filter_complex showwavespic -frames:v 1 output.png
This is working fine but it also takes too much time (Ofcourse only once ) to generate the image for remote video (i.e. We are saving videos on S3)
Problem with this i don’t get any library to integrate the waveform image with the Video.
Can someone suggest any better approach related to this.
