MediaSPIP Core : La Configuration
9 novembre 2010, parMediaSPIP Core fournit par défaut trois pages différentes de configuration (ces pages utilisent le plugin de configuration CFG pour fonctionner) : une page spécifique à la configuration générale du squelettes ; une page spécifique à la configuration de la page d’accueil du site ; une page spécifique à la configuration des secteurs ;
Il fournit également une page supplémentaire qui n’apparait que lorsque certains plugins sont activés permettant de contrôler l’affichage et les fonctionnalités spécifiques (...) -
Configuration spécifique d’Apache
4 février 2011, parModules spécifiques
Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

How to extract a video snippet from a video file that is being written in by ffmpeg in realtime
26 février 2015, par alex.bAt the moment i am recording a LIVE stream video from youtube with youtube-dl (https://github.com/rg3/youtube-dl)
The command i use for this :
youtube-dl --id -f 92 https://www.youtube.com/watch?v=VYlQJbsVs4892 is a format code that i got after executing a command to get the formats, that gave me this list :
format code extension resolution note
140 m4a audio only DASH audio 144k , m4a_dash container, aac @128k (48000Hz)
141 m4a audio only DASH audio 272k , m4a_dash container, aac @256k (48000Hz)

94 mp4 480p HLS
95 mp4 720p HLS
96 mp4 1080p HLS (best)This is creating a file called VYlQJbsVs48.mp4.part that gets bigger and bigger of course.
Is there a way to extract a video snippet from that live stream or form the part file ? Or maybe there is a better way of doing this ?
What i have noticed is that if i force quit iTerm2 while youtube-dl is running the .part file it creates wont contain any index information (something to do with an moov atom not being present in the mp4 file - which is the information about the number of frames and other things - metadata i think), so it makes me think i cannot extract from the file.
Maybe if there would be a way that youtube-dl can write the index information at all times or maybe another way that i can record the live stream and get video snippets while its recording.
I forgot to mention i am doing this on OSX Yosemite. I have FFMPEG installed with homebrew and youtoube-dl
I am more than happy to try stuff on UBUNTU if there is a solution.
Any help would be greatly appreciated.
Thank you.
