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.

Apache Tika 2.0.9 programm ffmpeg and exiftool not found ?
6 avril 2024, par mj44I use an JavaFX Maven Project to use Apache Tika Version 2.9.0.
The Java Test program will be finished and all methods that I create will done right.
I have in the log file a lot of DEBUG errors and Idon't know why ?
I habe spent many hours to clear the problem.


Here's an excerpt of the logfile


2024-04-03 14:56:12 [main] DEBUG org.apache.tika.parser.external.ExternalParser - exception trying to run ffmpeg
java.io.IOException: Cannot run program "ffmpeg": CreateProcess error=2, Das System kann die angegebene Datei nicht finden

The message says that ffmpeg and exiftool are not found.


This is my tika-config.xml


<?xml version="1.0" encoding="UTF-8"?>
<properties>
 <parsers>
 <parser class="org.apache.tika.parser.DefaultParser"></parser>
 <parser class="org.apache.tika.parser.pdf.PDFParser"></parser>

 </params>

 "D:\Tools\exiftool.exe"
 </params>
 </parser>
 </parsers>
 <detector>
 <detector class="org.apache.tika.detect.DefaultDetector"></detector>
 </detector>
</properties>


I tested the path of the programms in a console ant it worked fine ?
I don't know what I can do now ?


Thanks for Help


I have downloaded new copies of the ffmpeg and exiftool and installed them.
I tested it in a console to run and both tools work fine.
I tested the permissions, no problems with permissions
I tested that the tika-config.xml will be loaded, it loaded.

Babel Loader error when using ffmpeg.wasm in CRA react app
6 avril 2024, par Sooraj ChanduI am trying to implement a video editor using ffmpeg-wasm in CRA react app.


Package dependencies :


"@ffmpeg/ffmpeg": "^0.12.10",
"@ffmpeg/util": "^0.12.1",


Below is a sample class that I am trying to implement :


import React, {useRef, useState} from 'react';
import { FFmpeg } from "@ffmpeg/ffmpeg";
import { toBlobURL, fetchFile } from "@ffmpeg/util";

function Trimmer() {
 const [loaded, setLoaded] = useState(false);
 const ffmpegRef = useRef(new FFmpeg());
 const videoRef = useRef<htmlvideoelement null="null">(null)
 const messageRef = useRef<htmlparagraphelement null="null">(null)

 const load = async () => {
 const baseURL = "https://unpkg.com/@ffmpeg/core-mt@0.12.6/dist/esm";
 const ffmpeg = ffmpegRef.current;
 ffmpeg.on("log", ({ message }) => {
 if (messageRef.current) messageRef.current.innerHTML = message;
 });
 // toBlobURL is used to bypass CORS issue, urls with the same
 // domain can be used directly.
 await ffmpeg.load({
 coreURL: await toBlobURL(`${baseURL}/ffmpeg-core.js`, "text/javascript"),
 wasmURL: await toBlobURL(
 `${baseURL}/ffmpeg-core.wasm`,
 "application/wasm"
 ),
 workerURL: await toBlobURL(
 `${baseURL}/ffmpeg-core.worker.js`,
 "text/javascript"
 ),
 });
 setLoaded(true);
 };

 const transcode = async () => {
 const videoURL = "https://raw.githubusercontent.com/ffmpegwasm/testdata/master/video-15s.avi";
 const ffmpeg = ffmpegRef.current;
 await ffmpeg.writeFile("input.avi", await fetchFile(videoURL));
 await ffmpeg.exec(["-i", "input.avi", "output.mp4"]);
 const fileData = await ffmpeg.readFile('output.mp4');
 const data = new Uint8Array(fileData);
 if (videoRef.current) {
 videoRef.current.src = URL.createObjectURL(
 new Blob([data.buffer], { type: 'video/mp4' })
 )
 }
 };

 return loaded ? (
 <>
 <video ref="{videoRef}" controls="controls"></video>
 <br />
 <button>Transcode avi to mp4</button>
 <p ref="{messageRef}"></p>
 >
 ) : (
 <button>Load ffmpeg-core</button>
 );
}

export default Trimmer;
</htmlparagraphelement></htmlvideoelement>

I have installed the dependencies and when trying to start the application, it throws an error given below :


index.js:1 ./node_modules/@ffmpeg/ffmpeg/dist/umd/ffmpeg.js 55:4
Module parse failed: Unexpected character '#' (55:4)
File was processed with these loaders:
 * ./node_modules/babel-loader/lib/index.js
You may need an additional loader to handle the result of these loaders.
| new Error("failed to import ffmpeg-core.js");
| class i {
> #e = null;
| #t = {};
| #s = {};
