Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...) -

Error using FFmpeg.wasm for audio files in react : "ffmpeg.FS('readFile', 'output.mp3') error. Check if the path exists"
25 février 2021, par Rayhan MemonI'm currently building a browser-based audio editor and I'm using ffmpeg.wasm (a pure WebAssembly/JavaScript port of FFmpeg) to do it.


I'm using this excellent example, which allows you to uploaded video file and convert it into a gif :


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 [video, setVideo] = useState();
 const [gif, setGif] = useState();

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

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

 const convertToGif = async () => {
 // Write the file to memory 
 ffmpeg.FS('writeFile', 'test.mp4', await fetchFile(video));

 // Run the FFMpeg command
 await ffmpeg.run('-i', 'test.mp4', '-t', '2.5', '-ss', '2.0', '-f', 'gif', 'out.gif');

 // Read the result
 const data = ffmpeg.FS('readFile', 'out.gif');

 // Create a URL
 const url = URL.createObjectURL(new Blob([data.buffer], { type: 'image/gif' }));
 setGif(url)
 }

 return ready ? (
 
 <div classname="App">
 { video && 

 }


 <input type="file" />> setVideo(e.target.files?.item(0))} />

 <h3>Result</h3>

 <button>Convert</button>

 { gif && <img src="http://stackoverflow.com/feeds/tag/{gif}" width="250" style='max-width: 300px; max-height: 300px' />}

 </div>
 )
 :
 (
 <p>Loading...</p>
 );
}

export default App;


I've modified the above code to take an mp3 file recorded in the browser (recorded using the npm package 'mic-recorder-to-mp3' and passed to this component as a blobURL in the global state) and do something to it using ffmpeg.wasm :


import React, { useContext, useState, useEffect } from 'react';
import Context from '../../store/Context';
import Toolbar from '../Toolbar/Toolbar';
import AudioTranscript from './AudioTranscript';

import { createFFmpeg, fetchFile } from '@ffmpeg/ffmpeg';

//Create ffmpeg instance and set 'log' to true so we can see everything
//it does in the console
const ffmpeg = createFFmpeg({ log: true });

const AudioEditor = () => {
 //Setup Global State and get most recent recording
 const { globalState } = useContext(Context);
 const { blobURL } = globalState;

 //ready flag for when ffmpeg is loaded
 const [ready, setReady] = useState(false);

 const [outputFileURL, setOutputFileURL] = useState('');

 //Load FFmpeg asynchronously and set ready when it's ready
 const load = async () => {
 await ffmpeg.load();
 setReady(true);
 }

 //Use UseEffect to run the 'load' function on mount
 useEffect(() => {
 load();
 }, []);

 const ffmpegTest = async () => {
 //must first write file to memory as test.mp3
 ffmpeg.FS('writeFile', 'test.mp3', await fetchFile(blobURL));

 //Run the FFmpeg command
 //in this case, trim file size down to 1.5s and save to memory as output.mp3
 ffmpeg.run('-i', 'test.mp3', '-t', '1.5', 'output.mp3');

 //Read the result from memory
 const data = ffmpeg.FS('readFile', 'output.mp3');

 //Create URL so it can be used in the browser
 const url = URL.createObjectURL(new Blob([data.buffer], { type: 'audio/mp3' }));
 setOutputFileURL(url);
 }

 return ready ? ( 
 <div>
 <audiotranscript></audiotranscript>
 <toolbar></toolbar>
 <button>
 Edit
 </button>
 {outputFileURL && 
 
 }
 </div>
 ) : (
 <div>
 Loading...
 </div>
 )
}

export default AudioEditor;


This code returns the following error when I press the edit button to call the ffmpegTest function :



I've experimented, and when I tweak the culprit line of code to :


const data = ffmpeg.FS('readFile', 'test.mp3');


the function runs without error, simply returning the input file. So I assume there must be something wrong with ffmpeg.run() line not storing 'output.mp3' in memory perhaps ? I can't for the life of me figure out what's going on...any help would be appreciated !

ffmpeg - convert mxf to ts while maintaining "Text" tracks
15 février 2021, par user3552454I have a
.mxffile that has 608/708 captions. When I look at the MediaInfo of this file I see below Text information. My goal is to extract 608/708 captions from this file using ccextractor. To do that first I am converting this to a .ts file using below ffmpeg command asffmpeg -i abc.mxf -c:v mpeg2video -s 160x90 -b:v 300k -map 0:v -map 0:d abc.ts. But when I check the MediaInfo ofabc.tsfile I don't see any of "@type:Text" tracks in the output.

I also tried with
-copy_unknownbut still, I am not able to see "@type:Text" in output .ts file MediaInfo.

Also in some file I see
"MuxingMode": "Ancillary data / CDP"and some files I am seeing"MuxingMode": "A/53 / DTVCC Transport". What is the difference between these two ?

Request you to share your valuable feedback. Thank you.

FFMPEG, macOS Catalina : "ffmpeg stderr : /private/tmp/com.apple.launchd.ID/org.macosforge.xquartz:0 : Operation not supported on socket"
11 février 2021, par Bogdan SlyusarenkoI'm trying to record selenium test run with FFMPEG, for automation testing of web extensions (selenium+js/ts).
FFMPEG initiated by command :


const { spawn } = require("child_process");
 ffmpeg = spawn("ffmpeg", [
 "-x265-params",
 "-f",
 "xcbgrab", 
 "-video_size",

 "-loglevel",
 "debug", 
 "-y", 
 "-pix_fmt",
 "yuv420p",
 videoPath, 
 ]);


Return constantly error,related to process.DISPLAY, I'm not sure why it's so :
