Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

Revision 6919 : Gros changement... On change le pipeline diogene_champs_sup en ...
22 août 2012, par kent1 — LogGros changement...
On change le pipeline diogene_champs_sup en diogene_objets
Les champs_sup antérieurs $fluxarticle ?truc ? deviennent maintenant $fluxarticle ?champs_sup ?truc ?
On fait cela pour gérer d’autres propriétés spécifiques par objet comme :$fluxpage ?type_orig ? = ’article’ ; => indique que le type d’origine est article ;
$fluxpage ?diogene_max ? = 1 ; => indique que l’on ne peut avoir qu’un seul diogène de ce type ;
$fluxpage ?ss_rubrique ? = true ; => indique que ce type de diogène est sans rubrique, ne peut correspondre à 1 secteur ;

Error i got after run the code


= RESTART: D:\Bots\2vidpod.py
Traceback (most recent call last):
 File "D:\Bots\2vidpod.py", line 71, in <module>
 os.remove(os.path.join(output_folder, 'temp.mp4'))
FileNotFoundError: [WinError 2] Не удается найти указанный файл: 'D:\\bots\\ttvidads\\VID\\ZAGOTOVKI\\Videopod1\\temp.mp4'
</module>


so things i checked is
path is right
programs is installed FFMPEG and PYTHON all additional libraries downloaded
i pretty sure error caused by regular path and i wanna know if absolute path can do the thing

make webbased ffmpeg-live transcoder on linux for multiple streams
11 juillet 2017, par Dlniya DlzarHi I am planning to make webbased ffmpeg-live transcoder on linux for multiple streams .
Using ffmpeg and ngnix-rtmp is the basic that i found and planning to do it
my plan is (Web interface for adding and modifying streams (name ,input,output..)
in database , database i mean (json file). and execute ffmpeg command depend on the JSON file (now one more thing i want to do , is to monitor streams based on
nginx-rtmp-module/stat.xsl
git https://github.com/arut/nginx-rtmp-module/blob/master/stat.xsl
and restart streams if there is problem , like no audio or picture
whats is best structure to do it ?? which language is good to do the proccess
is there any missing knowledges ?? is there any other better way in your mind ??
