fftools/cmdutils : fix error message for "ffmpeg -init_hw_device list"
26 mars, par Jun Zhaofftools/cmdutils : fix error message for "ffmpeg -init_hw_device list"
When running 'ffmpeg -init_hw_device list' to display available hardware
devices, it incorrectly shows an error message :
"Failed to set value 'list' for option 'init_hw_device' : Immediate exit requested"This is a regression introduced by commit a50f90f1c23. The command is
actually working as intended - it should exit after listing devices, but
shouldn't display an error message.Signed-off-by : Jun Zhao <barryjzhao@tencent.com>

react cant find ffmpegwasm
18 septembre 2024, par MartinI am trying to create a working example for ffmpeg wasm with react js in my browser.


I have been following this very simple example :
https://www.youtube.com/watch?v=-OTc0Ki7Sv0&ab_channel=Fireship


installed ffmpeg locally inside my react repo node_modules as seen here :



And followed to tutorial video to edit the App.jsx so it looks like this :


import React, { useState, useEffect } from 'react';
import './App.css';

import { createFFmpeg, fetchFile } from '@ffmpeg/ffmpeg';
const ffmpeg = createFFmpeg({
 log: true,
});
function App() {
 
 const [ready, setReady] = useState(false);

 const load = async () => {
 console.log('load()')
 await ffmpeg.load();
 setReady(true);
 }

 useEffect(()=>{
 load();
 }, [])

 return (
 <div classname="App">
 content
 </div>
 );
}

export default App;



But this leads to error messages in my win10 command prompt terminal saying it cant find the ffmpeg files :


[16:07:47] [snowpack] [404] Not Found (/node_modules/@ffmpeg/core/dist/ffmpeg-core.js)
[16:07:47] [snowpack] [404] Not Found (/node_modules/@ffmpeg/core/dist/ffmpeg-core.wasm)
[16:07:47] [snowpack] [404] Not Found (/node_modules/@ffmpeg/core/dist/ffmpeg-core.worker.js)


I've even tried moving the ffmpeg files to my public folder and editing the code to find them like so :


const ffmpeg = createFFmpeg({
 log: true,
 corePath: '../public/@ffmpeg/core/dist/ffmpeg-core.js',
});


But the same error occured. Why doesn't my react App.jsx file correctly find the ffmpeg files in my node_modules folder ?
