• Can I dynamically call a LGPL/GPL software in my closed-source application ? [closed]

  29 juin 2016, par marcgg

  I want to use a tool (ffmpeg) that is under GNU Lesser General Public License, version 2.1 GNU General Public License (GPL) version 2 for some components.

  To do so, I only call it in my software as such :

  System.Diagnostics.Process p = new System.Diagnostics.Process();
  
  p.StartInfo = new System.Diagnostics.ProcessStartInfo("lgplSoftware.exe", myParams);
  
  p.Start();

  I do not change it, I only use a built version of the software for windows.

  Wikipedia says :

  A key dispute related to the GPL is
  whether or not non-GPL software can be
  dynamically linked to GPL libraries.
  The GPL is clear in requiring that all
  derivative works of code under the GPL
  must themselves be under the GPL.
  While it is understood that static
  linking produces derivative works, it
  is not clear whether an executable
  that dynamically links to a GPL code
  should be considered a derivative work
  (see Weak Copyleft). The
  free/open-source software community is
  split on this issue. The FSF asserts
  that such an executable is indeed a
  derivative work if the executable and
  GPL code "make function calls to each
  other and share data structures,"
  with certain others agreeing (e.g.
  Jerry Epplin), while some (e.g.
  Linus Torvalds) agree that dynamic
  linking can create derived works but
  disagree over the circumstances.

  I am really confused by all this legal things. I would have made my project LGPL as well and released the source, but this is not up to me.

  So the question is : can I use it like I’m doing right now or will I be executed by an army of lawyers ?

• MP4 codec support in Chromium

  18 mai 2018, par Staggan

  We have integrated Chromium Embedded Framework into our Windows game to allow us to render web pages from within our application, and everything works fine, except MP4 videos.

  I understand Chromium does not include this codec due to licensing issues, but can anyone provide details on how we can add support, even if we have to license a codec for it.

  All the information we can find seems to be old, and the functions referred to appear to be deprecated... so we are at a bit of a loss.

  All the video serving networks we have spoken to appear to serve MP4s.. so changing encoding does not seem to be an option.

  Any advice would be greatly appreciated.

  Thanks
