• Electron, Chromium and ffmpeg licencing confusion [closed]

  12 mars 2021, par Iamisti

  Intro :
Recently I'm working on an electron based application that is free to use but also has subscription based services.
It came to my attention that ffmpeg is shipped with electron, which has GPL/LGPL licence.

  


  My quetion is :

  


  

  • Am I legally able to still distribute the application and be licence-compliant with ffmpeg without owning any proper licence to it ? I thought chromium dealt with the licencing on this topic since so many applications nowadays are shipped with using electron and chromium under the hood.

  


  • How do I compile/build electron to make it licence compatible (in case its not ?)

  


  


  I did a lot of reseearch and I found out the followings :

  


  


  • ffmpeg is shipped with chromium, they built their own version of ffmpeg and it seems they also have licence for it. Although that might be that they just push the responsibility down on the software developer/company who distributes their application with chromium.
Chromium licence for ffmpeg : https://chromium.googlesource.com/chromium/third_party/ffmpeg/+/703e920bb75053bf6b87d41d198cbbfbce3fb7ad/LICENSE

    


  


  • Apparently ffmpeg has a checklist of how to be licence compliant. Does that mean if I do all these steps, I can still distribute the application and can legally use it ? Licence checklist for ffmpeg : http://ffmpeg.org/legal.html

    


  


  • checking out some popular electron applications like Discord, Figma, Slack, etc... they ALL have ffmpeg included cause of electron when you install them. I wonder how they made it legal ? I don't see any of these checklists done on any of these popular applications.

    


  


  


  I'm know very little regarding licences, so any help would be incredibly huge help for me.

  


• How to build SDL libraries for Android

  4 mars 2013, par Harish

  I am planning to use SDL (Simple DirectMedia Layer) to display video output in my Android application that uses ffmpeg libraries. I have downloaded the sources from http://www.libsdl.org/download-1.2.php and built (./configure, make & make install) on my Ubuntu. But when I use these .so files the Android ndk-build complains that "Could not read symbols. File in wrong Format".

  Can I use the .so files that are built on Ubuntu on Android or do I need to build the SDL for Android in a different way ?

• MEAN stack express.js video uploader/converter

  5 janvier 2017, par MattJ

  The idea is a social site where people can upload their videos. I am planning to use multer for uploading (limiting by size and by mimetype). Then for performance and mostly storage purposes to use fluent-ffmpeg and convert it to mp4 format and store it somewhere on the server with a reference in mongodb. Since I do not want the user to wait while the whole process is done, I plan to separate it into to main parts :

  1. Uploading
  2. Converting and storing.

  Where the user uploads the file and then some separate node process ( using node-schedule) which run checks every 1 min. or so to convert all files in the directory and after that adds the references to mongodb. So what do you guys think ? What is the best approach performance-wise ?
