Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

Demande de création d’un canal
12 mars 2010, parEn fonction de la configuration de la plateforme, l’utilisateur peu avoir à sa disposition deux méthodes différentes de demande de création de canal. La première est au moment de son inscription, la seconde, après son inscription en remplissant un formulaire de demande.

La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

cannot hear audio after saving RTSP stream as ts or avi or mp4 files using ffmpeg command
28 mai 2022, par ewangI am still new to ffmpeg and trying to save RTSP stream from the IP camera (Meraki MV2) via RTSP link (rtsp ://192.168.0.80:9000/live) to local laptop (Windows 10) as ts file, or avi or mp4 files, but none of them can hear sound. In Meraki MV2 camera dashboard audio is enabled
meraki dashboard audio enabled screenshot


And below is the ffmpeg command i used :


ffmpeg -use_wallclock_as_timestamps 1 -rtsp_transport tcp -i rtsp://192.168.0.80:9000/live -f mpegts -b 400k -r 25 -vcodec libx264 -s 640x480 -aspect 4:3 -bufsize 6000k -acodec aac -ab 56k -ac 2 -ar 22050 -bf 0 -level 30 -y record_a_v.ts


In below part of the result log, noticed Steam mapping has a #0:1 -> #0:0 and #0:0 -> #0:1, is it supposed to be crossed or not really ?

ffmpeg - Can't stably save rtsp stream to file
20 août 2022, par André LuísI'm trying to save the RTSP stream of this camera to file. However, at some point I'll get the following errors, which will stop the process.




video:331639kB audio:5199kB subtitle:0kB other streams:0kB global
headers:0kB muxing overhead : unknown




And a bunch of these, before the previous one :




Non-monotonous DTS in output stream 0:1 ; previous : 5439375, current :
5439283 ; changing to 5439376. This may result in incorrect timestamps
in the output file.




Here is the command I'm running :


ffmpeg "rtsp://192.168.0.100:554/cam/realmonitor?channel=1&subtype=0" -c copy -f segment -segment_time 00:01:00 -reset_timestamps 1 -segment_format mkv -strftime 1 /home/user/.camera/recordings/2022/8/19/%H_%M_%S.mkv


I've tried adding each of these parameters and they all together :


-fflags +autobsf+genpts -y -threads 1 -use_wallclock_as_timestamps 1 -dts_delta_threshold 0 -rtsp_transport tcp -i


ffprobe :
