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.

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.

Do I need multiple video files in different resolutions to use MPEG DASH ?
2 février 2023, par Gentil AlysonI'm trying to use Django REST Framework to serve .mpd files. When the user uploads a video, the server creates the MPD and the chunk files. However, I can't seem to able to make it work. I've tried using python-ffmpeg-video-streaming, but the client which is using dash.js to play the video will get only one bitrate (480p). I've also tried running this command
'ffmpeg -i {self.file.path} -map 0 -map 0 -c:a aac -c:v libx264 -b:v:0 800k -b:v:1 300k -var_stream_map "v:0,name:800k v:1,name:300k" -f dash -dash_segment_type mp4 -single_file 1 {file_dir}/dash.mpd'usingos.systemfrom Python, but then the player gets stuck at buffering.

Do I really need multiple video files in different resolutions ? If not, then how would I go about making the necessary files ? Thanks in advance !

WebM live streaming via DASH
4 juin 2018, par ewackI am following the instructions here to try to make WebM live streaming via DASH. My input is from an Axis camera and it is streaming as h264 encoding. I am using node to spin up the ffmpeg processes. I am able to create the .hdr file and the .chk files. The .mpd file is even created but it’s empty and I get an error saying :
Could not write header for output file #0 (incorrect codec parameters ?): Operation not permittedStream mapping: Stream #0:0 -> #0:0 (copy)Here’s all of my code :
var express = require('express');
spawn = require('child_process').spawn;
var app = express();
app.use(express.static(__dirname + '/public'));
app.listen(8080);
console.log("Running on Port 8080");
var ffmpeg1 = spawn('ffmpeg', [
