• Use ffmpeg from an electron app

  8 février 2017, par Sharath Huddar

  I intend to build a basic video editor desktop app. I have built a working prototype in python ( using kivy ). In this prototype I directly call the command line ffmpeg tool.

  How can I incorporate ffmpeg into my electron app ?

• How can I bundle a precompiled binary with electron

  13 avril 2017, par UltrasoundJelly

  I am trying to include a precompiled binary with an electron app. I began with electron quick start app and modified my renderer.js file to include this code that is triggered when a file is dropped on the body :

  spawn = require( 'child_process' ).spawn,
  
          ffmpeg = spawn( 'node_modules/.bin/ffmpeg', ['-i',clips[0],'-an','-q:v','1','-vcodec','libx264','-y','-pix_fmt','yuv420p','-vf','setsar=1,scale=trunc(iw/2)*2:trunc(ih/2)*2,crop=in_w:in_h-50:0:50', '/tmp/out21321.mp4']);
  
  
  
     ffmpeg.stdout.on( 'data', data => {
  
           console.log( `stdout: ${data}` );
  
          });
  
     ffmpeg.stderr.on( 'data', data => {
  
      console.log( `stderr: ${data}` );
  
          });

  I have placed my precompiled ffmpeg binary in node_modules/.bin/. Everything works great in the dev panel, but when I use electron-packager to set up the app, it throws a spawn error ENOENT to the console when triggered. I did find a very similar question on SO, but the question doesn’t seem to be definitively answered. The npm page on electron-packager does show that they can be bundled, but I cannot find any documentation on how to do so.

• Supporting HEVC/H.265 videos in Electron

  1er mars 2021, par Elmo

  Chrome/Electron don't normally support H.265 videos. I want the user to be able to play .mov files recorded by Apple devices in my app. How can I do this ?

  


  Possible approaches :

  


  

  1. Use ffmpeg to transcode to H.264 in real-time, which will be resource intensive (not ideal)

  


  2. Use WebAssembly to render the video in a <canvas></canvas> tag (not ideal)

  


  3. Fork and manually add H.265 codec support to Chrome/Electron (overkill)

  


  4. Use a native module that renders the video in a <canvas></canvas> or BrowserView
