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.

Convert png images to HEVC with alpha video via ffmpeg [closed]
6 mai 2024, par foxhableI am trying to create a video from a sequence of png images in the HEVC with alpha codec via ffmpeg.


After the command


ffmpeg -i a%d.png -r 30 -c:v hevc_videotoolbox -allow_sw 1 -alpha_quality 1 -vtag hvc1 ffmpeg-hevc.mov


I get a video with a transparent background that opens in QuickTime, but not Safari.


Info about this video via ffprobe :


ffprobe .\ffmpeg-hevc.mov
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '.\ffmpeg-hevc.mov':
 Metadata:
 major_brand : qt
 minor_version : 512
 compatible_brands: qt
 encoder : Lavf61.3.103
 Duration: 00:00:12.77, start: 0.000000, bitrate: 3437 kb/s
 Stream #0:0[0x1]: Video: hevc (Main) (hvc1 / 0x31637668), yuv420p(tv, bottom coded first (swapped)), 1920x1920, 3435 kb/s, 30 fps, 30 tbr, 15360 tbn (default)
 Metadata:
 handler_name : VideoHandler
 vendor_id : FFMP
 encoder : Lavc61.5.103 hevc_videotoolbox


I compared this to a video that has a transparent background and works in Safari and QuickTime


ffprobe movie-hevc.mov
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '.\movie-hevc.mov':

The only thing I noticed is the encoder. In the working version this is HEVC but in my Lavc61.5.103 hevc_videotoolbox.


The question is, is it possible to create a video with a native HEVC codec via ffmpeg ?
