• Ubuntu 16.04 + ffmpeg [on hold]

  19 janvier 2017, par Nick Deny

  On Ubuntu 14.04 my command working normally, but on Ubuntu 16.04 it’s error. I don’t know why, can somebody help ?

• avcodec/indeo2 : Remove #ifdef BITSTREAM_READER_LE cruft

  12 octobre 2020, par Andreas Rheinhardt

  avcodec/indeo2 : Remove #ifdef BITSTREAM_READER_LE cruft
  Before the LE bitstream reader was used in the Indeo 2 decoder,
  
  a standard BE bitstream reader with swapped bits was used ; when the LE
  
  bitstream reader was added, the old code was only #ifdef'ed away and not
  
  removed. Said code has several problems : It modifies the input packet
  
  without ensuring that the packet is indeed writable ; and it doesn't work
  
  since 09c4e5c5988c0037d108c5fc2a137d9ad488f7f4 because said commit
  
  removed the BE table used to initialize the VLC table. So just remove
  
  this cruft from the actual decoder, too.
  Also use INIT_LE_VLC_STATIC while at it.

• 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.
