Add coverart into ogg containing an opus audio stream with ffmpeg without re-encoding the audio stream
12 décembre 2023, par SebMaI'm trying to add a coverart into an ogg file with
ffmpeg:



Here are my
source.oggandsource.jpgfiles :


$ ffprobe -hide_banner source.ogg 
Input #0, ogg, from 'source.ogg':
 Duration: 00:03:02.45, start: 0.007500, bitrate: 73 kb/s
 Stream #0:0: Audio: opus, 48000 Hz, stereo, fltp
 Metadata:
 DURATION : 00:03:02.441000000
 ENCODER : Lavf58.20.100
$ identify source.jpg 
source.jpg JPEG 480x360 480x360+0+0 8-bit DirectClass 15.1KB 0.000u 0:00.000



I tried this :



$ ffmpeg -hide_banner -i source.ogg -i source.jpg -map 0 -map 1 -c:a copy -c copy -map_metadata 0 dest.ogg -y && echo && ffprobe -hide_banner dest.ogg 
Input #0, ogg, from 'source.ogg':

I've also found this answer but it does not explain how to do it with
ffmpeg.


I've read about a "METADATA_BLOCK_PICTURE" metadata in the ogg container that might contain the picture in base64, so I tried this :



$ ffmpeg -hide_banner -i source.ogg -map 0 -c:a copy -c copy -metadata METADATA_BLOCK_PICTURE="$(base64 source.jpg)" dest.ogg
Input #0, ogg, from 'source.ogg':

It kinda "worked", but neither
ffplaynormpvcan parse the cover art :


$ ffplay -hide_banner dest.ogg

Problem importing whatsapp-web.js nodejs module in electron react app
26 mai 2021, par Sunil ShahI am trying to build an electron react app. I need to integrate this node modules https://www.npmjs.com/package/whatsapp-web.js in my electron react app. My main.js of electron looks like this :




// Modules to control application life and create native browser window
const { app, BrowserWindow } = require("electron");
const path = require("path");

function createWindow() {
 // Create the browser window.
 const mainWindow = new BrowserWindow({
 width: 800,
 height: 600,
 webPreferences: {
 webSecurity: false,
 },
 });

 // and load the index.html of the app.
 mainWindow.loadURL("your ip address:3000");

 // Open the DevTools.
 // mainWindow.webContents.openDevTools()
}

app.whenReady().then(() => {
 createWindow();

 app.on("activate", function () {
 // On macOS it's common to re-create a window in the app when the
 // dock icon is clicked and there are no other windows open.
 if (BrowserWindow.getAllWindows().length === 0) createWindow();
 });
});

// Quit when all windows are closed, except on macOS. There, it's common
// for applications and their menu bar to stay active until the user quits
// explicitly with Cmd + Q.
app.on("window-all-closed", function () {
 if (process.platform !== "darwin") app.quit();
});

// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.






And the React code where i want to import whatsapp-web.js module looks like




import React from "react";
import styled from "styled-components";
const qrcode = require('qrcode-terminal');
const Client = require('whatsapp-web.js');
function Error() {
 var client = new Client();
 client.initialize();
 console.log(client);
 console.log(qrcode);
 return (
 <container>
 <errorimage src="https://cdn4.iconfinder.com/data/icons/smiley-vol-3-2/48/134-512.png"></errorimage>
 <errormessage>Oops, you are not connected to any number.</errormessage>
 </container>
 );
}

export default Error;

const Container = styled.div`
 display: flex;
 height: 100vh;
 width: 100%;
 padding-top: 20vh;
 position: center;
 /* align-items: center; */
 justify-content: center;
`;

const ErrorImage = styled.img`
 background-color: transparent;
 background-repeat: no-repeat;
 background-size: cover;
 object-fit: contain;

 width: 25%;
 height: 25%;

 /* border: 2px solid black; */
`;

const ErrorMessage = styled.div`
 margin: 10px;
 width: 50%;
 height: 25%;
 /* top: 20px; */
 font-size: 30px;
 align-items: center;
 font-family: "Lucida Console", "Courier New", monospace;
 /* font-weight: bold; */
`;






Now everytime I try to import const Client = require('whatsapp-web.js') It throws error like this :
**
[0] ./node_modules/fluent-ffmpeg/index.js
[0] Module not found : Can't resolve './lib-cov/fluent-ffmpeg' in 'D :\Sunil\Zarir_app-main\Zarir_app-main\node_modules\fluent-ffmpeg'
[0] Compiling...
[0] Failed to compile.


and I tried the solution
https://github.com/fluent-ffmpeg/node-fluent-ffmpeg/issues/573#issuecomment-305408048
and other resources but still nothing works and just loops in errors and errors.
Please help if you have any information related to it.
Thank you.
