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.

Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs
12 avril 2011, parLa manière la plus simple d’ajouter des informations aux auteurs est d’installer le plugin Inscription3. Il permet également de modifier certains comportements liés aux utilisateurs (référez-vous à sa documentation pour plus d’informations).
Il est également possible d’ajouter des champs aux auteurs en installant les plugins champs extras 2 et Interface pour champs extras. -
Que fait exactement ce script ?
18 janvier 2011, parCe script est écrit en bash. Il est donc facilement utilisable sur n’importe quel serveur.
Il n’est compatible qu’avec une liste de distributions précises (voir Liste des distributions compatibles).
Installation de dépendances de MediaSPIP
Son rôle principal est d’installer l’ensemble des dépendances logicielles nécessaires coté serveur à savoir :
Les outils de base pour pouvoir installer le reste des dépendances Les outils de développements : build-essential (via APT depuis les dépôts officiels) ; (...)

Evolution #3963 (Nouveau) : Rediriger l’accueil d’un site non installé vers /ecrire
18 juin 2017, par Valéry -Lors du processus d’installation d’un SPIP la page d’accueil affiche un message "revenez plus tard" et il faut aller sur /ecrire pour procéder à l’installation.
Comme le souligne l’article https://makina-corpus.com/blog/metier/2017/passer-de-spip-a-drupal ce n’est pas intuitif pour quelqu’un qui réalise sa première installation de SPIP.
Le cas d’usage a priori est que lorsqu’on dépose les fichiers d’un SPIP sur un serveur c’est pour l’installer. Ne serait-il pas plus simple pour les néophytes de rediriger directement vers l’install ?

Can ffmpeg copy parts from an rmvb file without re-encoding ?
24 juin 2017, par Eng. M.HamdyI want to fast copy parts from an rmvb file without re-encoding. This command works fine with mp4 files but not with rmbv (I dropped start time and duration here) :
ffmpeg -i input -c copy output
when I use it with rmvb like this :
ffmpeg -i 1.rmvb -c copy 1.mp4
I get this error :
[mp4 @ 00bb8980] Could not find tag for codec rv40 in stream #0, codec
not curre ntly supported in container Could not write header for
output file #0 (incorrect codec parameters ?) : Invali d argument
Stream mapping : Stream #0:1 -> #0:0 (copy) Stream #0:0 -> #0:1
(copy)I also tried this :
ffmpeg -i 1.rmvb -c copy 2.rmvb
and got this error :
[NULL @ 04748980] Unable to find a suitable output format for ’2.rmvb’
2.rmvb : Invalid argumentI tried this command :
ffmpeg -i 1.rmvb -c:v copy -c:a aac -strict experimental -b:a 128k 1.mp4
and got this error :
[mp4 @ 046e0020] Could not find tag for codec rv40 in stream #0, codec
not curre ntly supported in container Could not write header for
output file #0 (incorrect codec parameters ?) : Invali d argument Error
initializing output stream 0:1 — [aac @ 046e1bc0] Qavg : nan
Conversion failed !I read this topic :
but the solution does not work for me.. After many trials, this is the command that worked (and took too long time) :ffmpeg -i 1.rmvb -c:v libx264 -b:a 32k output.mp4
But I do not want to re-encode the file. Any solution ?
Edit :
I tried :ffmpeg -i 1.rmvb -c copy 1.mkv

[mp4 @ 0x7f15299c4520] Could not find tag for codec none in stream #2, codec not currently supported in container
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argumentStream mapping:
Stream #0:0 -> #0:0 (copy)
Stream #1:0 -> #0:1 (copy)
Stream #2:0 -> #0:2 (copy)
Stream #3:0 -> #0:3 (copy)
Last message repeated 1 timesThis gives the error :
Could not find tag for codec none in stream #2, codec not currently supported in container
Could not write header for output file #0 (incorrect codec parameters ?) : Invalid argumentSo I tried playing with the map like this :
-map 2:s
==> Gives me :
Stream map ’2:s’ matches no streams.
To ignore this, add a trailing ’ ?’ to the map.-map 2:s ?
==> Gives me no error, but the subtitle stream isn’t added into the final file.Stream mapping:
Stream #0:0 -> #0:0 (copy)
Stream #1:0 -> #0:1 (copy)
Stream #3:0 -> #0:2 (copy)Maybe I first have to convert the subtitle into srt or such, but for that I don’t find on google what type of file this is.
Any help would be greatly appreciated !
Thanks
---EDIT---
Hereby the code that I am using to convert this in PHP :
private function convert_TTML_subtitle_file($orig) {
if ( $orig == '' || !file_exists($orig) ) {
return false;
}
$f = file_get_contents($orig);
$pos = stripos($f, '<tt xmlns="http://www.w3.org/ns/ttml" if="if" false="false" return="return" while="while">body->div->p as $p ) {
$txt .= "{$counter}\r\n";
$counter++;
$txt .= $p['begin'] . ' --> ' . $p['end'] . "\r\n";
$txt .= $p->span . "\r\n\r\n";
}
}
$cur += $curSize;
}
$fname = tempnam(getcwd(), 'sub');
file_put_contents($fname, $txt);
return $fname;
}
</tt>
