La file d’attente de SPIPmotion
28 novembre 2010, parUne file d’attente stockée dans la base de donnée
Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...) -
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 (...) -
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.
La documentation de l’utilisation du script d’installation (...)

How to include audio in an overlay ffmpeg command ?
27 avril 2021, par gilad sUsing ffmpeg I add a video overlay successfully over an origin video (origin has audio, overlay doesn't). However the audio of the origin video doesn't appear in the result video.


ffmpeg -i source.mp4 -i overlay.mp4 -filter_complex "[0:v]setpts=PTS-STARTPTS, scale=1280x720[top]; 
 [1:v]setpts=PTS-STARTPTS, scale=1280x720, format=yuva420p, 
 colorchannelmixer=aa=0.2[bottom]; [top][bottom]overlay=shortest=1" 
 -shortest -acodec copy -vcodec libx264 result1.mp4


Even if I execute the following separate command on the result of the previous command - still no audio appears in the new result video.


ffmpeg -i result1.mp4 -i audio.mp3 -c:v copy -c:a aac result2.mp4


Here is the log :

Two nearly identical ffmpeg commands, one works, the other freezes up
