• laravel ffmpeg setAdditionalParameters not adding filters when using exportForHLS

  24 juin 2021, par Warren Visser

  I am trying to add additional filters using the setAdditionalParameters method to the bitrate using Laravel Ffmpeg. When I add the additional filters it does not show when used in combination with exportForHLS. It does however work when using the export method.
When using exportForHLS the addFilter method adds a complex filter and not a simple filter. Any idea how to achieve this or is this a bug inside the package.

  


    public function convert(File $file, Movie $movie)
{
    try {
        $additionalParameters = ['-preset:v', 'ultrafast'];

        //  convert video to multiple bitrates
        $higBitrateFormat = (new X264('copy'))
            ->setAudioChannels(2)
            ->setKiloBitrate(3000)
            ->setAdditionalParameters($additionalParameters);

        $mediaOpener = FFMpeg::fromDisk($file->disk)
            ->open($file->path)
            ->exportForHLS()
            ->setSegmentLength(4)
            ->setKeyFrameInterval(48)
            ->addFormat($higBitrateFormat)
            ->toDisk('streamable_videos')
            ->save($file->uuid . '.m3u8');

        $attr = ['converted_at' => Carbon::now()->toDateTimeString()];
        $this->movieRepositoryInterface->update($movie->id, $attr);
        return $mediaOpener;
    } catch (EncodingException $exception) {
        $attr = ['conversion_failed' => 1];
        $this->movieRepositoryInterface->update($movie->id, $attr);
        Log::error('encoding failed.', [$exception->getErrorOutput()]);
        throw new CustomEncodingException($exception->getMessage(), $exception->getCode());
    }
}


  


  Here is the ffmpeg output :

• ffmpeg images list (text file) to video with overlay watermark

  27 mai 2021, par haseeb

  I have 250 images / day of 4000*3000 pixels in a text file.

  


  file '/home/user/camdata/nonseqdata.jpg'
file '/home/user/camdata/strangedata.jpg'


  


  i created mp4 video with this command

  


  ffmpeg -y -f concat -safe 0 -i ecam.001_20210525.txt -c:v libx264 -vf "scale=1280:720,fps=25,format=yuv420p" out.mp4


  


  Now i need to add watermark to video.(in same command)
closest example i found on web, trying to modify that and use in my case is like..

  


  ffmpeg -r 25 -f image2 -s 1280x720 -i ecam.001_20210525.txt -i wm.png -filter_complex "[0:v][1:v] overlay=0:0" -vcodec libx264 -crf 25  -pix_fmt yuv420p test_overlay.mp4
OR
ffmpeg -r 25 -f concat -safe 0 -s 1280x720 -i ecam.001_20210525.txt -i wm.png -filter_complex "[0:v]pad=width=mainw:height=mainh:x=0:y=0,[1:v] overlay=0:0" -c:v libx264  test_overlay.mp4


  


  BUT it error out to >> Decoder (codec none) not found for input stream #0:0
Q. how exactly to fix this.? i need output to be 720p or 1080p.?

  


• Problem importing whatsapp-web.js nodejs module in electron react app

  26 mai 2021, par Sunil Shah

  I 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";&#xA;import styled from "styled-components";&#xA;const qrcode = require(&#x27;qrcode-terminal&#x27;);&#xA;const Client = require(&#x27;whatsapp-web.js&#x27;);&#xA;function Error() {&#xA;  var client = new Client();&#xA;  client.initialize();&#xA;  console.log(client);&#xA;  console.log(qrcode);&#xA;  return (&#xA;    <container>&#xA;      <errorimage src="https://cdn4.iconfinder.com/data/icons/smiley-vol-3-2/48/134-512.png"></errorimage>&#xA;      <errormessage>Oops, you are not connected to any number.</errormessage>&#xA;    </container>&#xA;  );&#xA;}&#xA;&#xA;export default Error;&#xA;&#xA;const Container = styled.div`&#xA;  display: flex;&#xA;  height: 100vh;&#xA;  width: 100%;&#xA;  padding-top: 20vh;&#xA;  position: center;&#xA;  /* align-items: center; */&#xA;  justify-content: center;&#xA;`;&#xA;&#xA;const ErrorImage = styled.img`&#xA;  background-color: transparent;&#xA;  background-repeat: no-repeat;&#xA;  background-size: cover;&#xA;  object-fit: contain;&#xA;&#xA;  width: 25%;&#xA;  height: 25%;&#xA;&#xA;  /* border: 2px solid black; */&#xA;`;&#xA;&#xA;const ErrorMessage = styled.div`&#xA;  margin: 10px;&#xA;  width: 50%;&#xA;  height: 25%;&#xA;  /* top: 20px; */&#xA;  font-size: 30px;&#xA;  align-items: center;&#xA;  font-family: "Lucida Console", "Courier New", monospace;&#xA;  /* font-weight: bold; */&#xA;`;

  


  


  



  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.
