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.

ffmpeg xfade audio out of sync
1er décembre 2020, par Richardhi I am using ffmpeg xfade to concat two clips, the transition looks fine, but the second clip has no audio in the output. I don't find more information about this in https://trac.ffmpeg.org/wiki/Xfade and the official doc. Can I keep the audio of both clips in sync ?


I'm puttting the complete log below, it's massive


ffmpeg -i teacher1.mp4 -i teacher2.mp4 -filter_complex xfade=transition=fadewhite:duration=1:offset=14.5 output.mp4

ffmpeg.wasm - How to do literally anything with a blob url
24 novembre 2024, par SeriousLeeI'm using the ffmpeg.wasm for the first time and I can't get anything working, beyond loading it. I have this function that does nothing in particular (I got it from the vite + react example in the docs, slightly modified) and all I want to do is pass it a blob URL like this
blob:http://localhost:5173/c7a9ea7c-aa26-4f4f-9c80-11b8aef3e81fand run through the function and have it give me anything back. But instead, it hangs on theffmpeg.execcommand and never completes. And yes, I've determined that the input blob does work - it's an 8MB, 12-second long mp4 clip.

Here's the function :


const processOutputVideo = async (videoURL) => {
 const ffmpeg = ffmpegRef.current;

 await ffmpeg.writeFile("input.mp4", await fetchFile(videoURL));
 await ffmpeg.exec(["-i", "input.mp4", "output.mp4"]);

 const fileData = await ffmpeg.readFile("output.mp4");
 const blob = new Blob([fileData.buffer], { type: "video/mp4" });
 const blobUrl = URL.createObjectURL(blob);

 return blobUrl;
 };


And here's the ffmpeg logs from my terminal.
