Menus personnalisés
14 novembre 2010, parMediaSPIP utilise le plugin Menus pour gérer plusieurs menus configurables pour la navigation.
Cela permet de laisser aux administrateurs de canaux la possibilité de configurer finement ces menus.
Menus créés à l’initialisation du site
Par défaut trois menus sont créés automatiquement à l’initialisation du site : Le menu principal ; Identifiant : barrenav ; Ce menu s’insère en général en haut de la page après le bloc d’entête, son identifiant le rend compatible avec les squelettes basés sur Zpip ; (...) -
MediaSPIP Init et Diogène : types de publications de MediaSPIP
11 novembre 2010, parÀ l’installation d’un site MediaSPIP, le plugin MediaSPIP Init réalise certaines opérations dont la principale consiste à créer quatre rubriques principales dans le site et de créer cinq templates de formulaire pour Diogène.
Ces quatre rubriques principales (aussi appelées secteurs) sont : Medias ; Sites ; Editos ; Actualités ;
Pour chacune de ces rubriques est créé un template de formulaire spécifique éponyme. Pour la rubrique "Medias" un second template "catégorie" est créé permettant d’ajouter (...) -
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.

FFMPEG stuck at 00:00:00 speed=0x for a long time at the beginning
4 juin 2020, par lagmoellertimI'm currently writing a script that can remove silence from any video. I'm doing this using ffmpeg and a complex_filter script.



Since most of my videos are pretty long (>1.5h), ffmpeg is called multiple times with a different complex_filter, each editing a part of the video (about 8 minutes long each) and combining those parts at the end.



The input file for all these separate parts is always the original 1.5h video clip.



The problem I keep getting is that for videos starting not directly at the start (first part works fine, second part starting at minute 8 takes longer, third part starting at minute 16 even longer, ... you get the point), this shows up and gets displayed for quite a long time, until it finally works with its normal speed :



frame= 0 fps=0.0 q=0.0 size= 0kB time=00:00:00.00 bitrate=N/A speed= 0x


Here is the ffmpeg script I use



ffmpeg -i video.mp4 -vsync 1 -async 1 -safe 0 -filter_complex_script /path/to/complex_filter -y -map '[vout]' -map '[aout]' video_parts/infb4_3.mp4


I also tried adding
-ss 00:24:00before or behind the-iinput, but I did not notice any speed improvement.


And here the complex_filter of one part of the video, starting at minute 24 and ending at minute 32 :

FFmpeg make video from figures and speed up a chosen part
11 juin 2020, par user13720066Make a video from a series of 100 figures



ffmpeg -framerate 10 -i input_figure%01d.png out.mp4



How can I only make figure numbers from [0-49] with a slower speed like
-framerate 5?


My try is



ffmpeg -start_number 1 -framerate 5 -i input_figure%01d.png -vframes 49 \
-start_number 50 -framerate 10 -i input_figure%01d.png \
out.mp4 



Doesn't work

How to speed up sound and video and modify the pitch ?
3 août 2020, par DiREKTI want to increase speed on both the sound and the video, while adding pitch to the audio alone.


I have those two ffmpeg commands, but I don't know how to make them work together.


ffmpeg -i input.mkv -filter_complex "[0:v]setpts=0.94*PTS[v];[0:a]atempo=1.06[a]" -map "[v]" -map "[a]" output.mkv


and


ffmpeg -i input.mkv -filter:a "atempo=1.06,asetrate=44100*1.25" output.mkv
