Changer son thème graphique
22 février 2011, parLe thème graphique ne touche pas à la disposition à proprement dite des éléments dans la page. Il ne fait que modifier l’apparence des éléments.
Le placement peut être modifié effectivement, mais cette modification n’est que visuelle et non pas au niveau de la représentation sémantique de la page.
Modifier le thème graphique utilisé
Pour modifier le thème graphique utilisé, il est nécessaire que le plugin zen-garden soit activé sur le site.

ANNEXE : Les extensions, plugins SPIP des canaux
11 février 2010, parUn plugin est un ajout fonctionnel au noyau principal de SPIP. MediaSPIP consiste en un choix délibéré de plugins existant ou pas auparavant dans la communauté SPIP, qui ont pour certains nécessité soit leur création de A à Z, soit des ajouts de fonctionnalités.
Les extensions que MediaSPIP nécessite pour fonctionner
Depuis la version 2.1.0, SPIP permet d’ajouter des plugins dans le répertoire extensions/.
Les "extensions" ne sont ni plus ni moins que des plugins dont la particularité est qu’ils se (...) -
Les statuts des instances de mutualisation
13 mars 2010, parPour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.
Les différents statuts possibles sont : prepa (demandé) qui correspond à une instance demandée par un utilisateur. Si le site a déjà été créé par le passé, il est passé en mode désactivé. publie (validé) qui correspond à une instance validée par un (...)

ffmpeg conversion from Flac to Ogg produces corrupted files
8 avril 2021, par experimentali transcoded flac files to ogg using this command


ffmpeg -i input.flac -c:a libvorbis -b:a 500k output.ogg


yes i use 500k to keep the highest quality possible, some of the files are ok, but some of them can not be played - Unsupported format or corrupted file says the foobar - also my icecast streamer cant read it. So there is something wrong with the files.


I believed it was due to the high bitrate so I tried


ffmpeg -i input.flac -c:a libvorbis -b:a 320k output.ogg


the same happened, some files were ok, some were not playable.
so I tried again with default using this command


ffmpeg -i input.flac -c:a libvorbis output.ogg


same thing. some files were ok, some were corrupted and not playable.


i have no clue why.


both flac and ogg are in the same family, what happened during the transcoding that it became a corrupted file ?


the spectral analysis does not show anything wrong - here it the ogg https://prnt.sc/115zdjl, here is the original flac https://prnt.sc/115zegw


i am really interested what is going on and how to make it work ?


can anyone explain ?


here is complete log

Dash.js not playing mpd files made with ffmpeg
31 décembre 2022, par MacsterI'm using ffmpeg to create chunks and manifest of a webm file which I want to live stream with Dash.js. Unfortunately Dash.js won't play the mpd file, no matter which way I create the chunks and manifest. However, the sample mpd URL from Dash.js is working.

UPDATE


Well, it seems like the problem in general was, that the mpd's wouldn't play from that /dash folder. So i took a look into the code and found a bad routing. Anyways, the mpd would't start with the given command I used, probably becasue it creates a
dynamicmanifest, like @Markus Schumann says. So I'm going with a new one which seems to be working for now, but not very well.

in the (2) => when I try to ffmpeg -i file.mp4 output somewhere : I get "moov atom not found" so the (2) can't read or open (1).


What I'm I missing


in (1)
-movflags +faststartdoesn't seem to fix the issue

••••••• EDIT : more details on the context ••••••


I'm using openvidu : webrtc with kurento and coturn.


The record feature creates a .mp4 on the fly as the chat is going on.


To start the recording, there is an API call i can make to my server and it automatically stops when all users leaves the chatroom OR do an other api call to stop. see composed video in this link https://docs.openvidu.io/en/2.17.0/advanced-features/recording/


openvidu have also webhooks.


My problem is not how to stop ffmpeg, but getting FFMPEG to encode while the mp4 or other is being generated "on the fly".


There is 2 options :


OPTION 1 : individual => 1 .webm per camare => this .webm ffmpeg can restream as hls or RTMP => it's working.


OPTION 2 : ** but the issue is with "Composed" video => it's using ffmpeg to x11grab the session... but it's mp4 without moov ato, so ffmpeg don't do anything with this.


see the composed.sh script here
https://github.com/OpenVidu/openvidu/blob/master/openvidu-server/docker/openvidu-recording/scripts/composed.sh


***************** EDIT 3 *************


in the .sh this is the part that is creating the mp4


ffmpeg -y -f alsa -i pulse -f x11grab -draw_mouse 0
-framerate $FRAMERATE -video_size $RESOLUTION -i :$DISPLAY_NUM
-c:a aac -c:v libx264 -preset ultrafast
-crf 28 -refs 4 -qmin 4 -pix_fmt yuv420p
-filter:v fps=$FRAMERATE "/recordings/$VIDEO_ID/$VIDEO_NAME.$VIDEO_FORMAT"


How can I modify this to have better result example VP8 or VP9 with good quality .webm so that the ffpmeg second command(2) can encode it live...


**** EDIT 4 ********


I tried this it worked for 30 seconds and suddenly stopped
