• How to fix ffmpeg,js length error in react-js project | fix error in react project

  19 février 2024, par X3R0

  I've tried to import the ffmpeg js library into my react-typescript project, I can't really update my project's react version or react-scripts due to the current code base.

  


  Error

  


  ./node_modules/@ffmpeg/ffmpeg/dist/umd/ffmpeg.js
TypeError: REDACTED_PROJECT_ROOT\node_modules\@ffmpeg\ffmpeg\dist\umd\ffmpeg.js: Cannot read properties of undefined (reading 'length')


  


  Code

  


  import React, { useEffect, useRef, useState } from 'react';
import { FFmpeg } from '@ffmpeg/ffmpeg';

/* MORE CODE HERE */

const ffmpeg = new FFmpeg();
const baseURL = 'https://unpkg.com/@ffmpeg/core@0.12.6/dist/umd';
const coreURL = `${baseURL}/ffmpeg-core.js`;
const wasmURL = `${baseURL}/ffmpeg-core.wasm`;
const coreData = await fromURLToBlob(coreURL);
const wasmData = await fromURLToBlob(wasmURL);
const coreBlob = new Blob([coreData], { type: "text/javascript"});
const wasmBlob = new Blob([wasmData], { type: "application/wasm"});
await ffmpeg.load({
    coreURL: fromBlobToURL(coreBlob),
    wasmURL: fromBlobToURL(wasmBlob),
});

• Use pre-built libffmpeg.so in Android Project

  26 juin 2013, par Aditya Kumar Praharaj

  Is it possible to use a pre-built ffmpeg library , libffmpeg.so (well preferrably the one open-source) in my own Android Project ? If so , then how would you :

  1 . include it in your project directory ?

  2 . modify Android.mk given that it is a shared library ?

  Thanks
