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 ;

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" (...) -
Support de tous types de médias
10 avril 2011Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

Revision de6ecc5ac3 : Selective masking of split modes. Allow selective masking of individual split m
4 octobre 2013, par Paul WilkinsChanged Paths :
Modify /vp9/encoder/vp9_onyx_if.c
Modify /vp9/encoder/vp9_onyx_int.h
Selective masking of split modes.Allow selective masking of individual split modes rather than
just a single on / off flag.For speed 2 recovers the large speed loss seen for some derf
clips in change Ie6bdfa0a370148dd60bd800961077f7e97e67dd4
and a small quality gain.For speed 1 10 % speed increase observed locally on some derf clips
for minimal quality change.Change-Id : If86191087b93cbc05351c26c60c7933e2149e485

Using an IF-Statement inside a drawtext (FFMPEG)
22 janvier 2020, par MonsterDruide1I’m currently trying to implement a timer on a video with FFMPEG, so it should start at 00.00 and start timing after a number of frames and stop timing again after a set amount of frames. So the timer should work like this :
00:00
00:00
00.00
(start timing)00.01
00.02
[...]
05.88
05.89
(stop timing)05.89
05.89
05.89
So far I’ve got the following as (minimal) command :
ffmpeg -i input.mp4
-filter_complex "[0:v]drawtext=fontfile='C\\:font.ttf':
text='%{eif\\:n/30\\:d\\:2}\\:%{eif\\:((mod(n,30))/30)*100\\:d\\:2}':
fontcolor=black:fontsize=55:x=(1705.5-(text_w/2)):y=(1000.5-(text_h/2)),format=yuv420p"
-pix_fmt yuv420p -c:a copy out.mp4There is some more stuff inside of the filter_complex, so I can’t replace that with
-vf
or similar.Thanks for all of your help !

Add buffering to real time input stream with c++ ffmpeg
7 octobre 2018, par JoelI am writing a c++ program in which I am handling a real time udp video stream with the ffmpeg library.
The video input fps is 25 frames per second in avarage. The gap between two frames can be 10 , 20, 40 milliseconds, but sometimes it can be around 80 milliseconds.
In those times, when the gap is around 80 milliseconds, the video seems choppy or stuck,When I open the same stream with the ffplay player(using the ffplay.exe), using a simple
"ffplay.exe udp ://ip:port" command, the video has a little delay (around 50 millisends) with respect to the origin stream, but it runs much more smoothly.Can I set a buffering time or any minimal delay so that the delay between the frames will be much more steady, in my c++ program ?
If so, how can I do this ?Thanks,
Joel
