[FFmpeg-user] Licensing fees

[Spencer Graves]

       The Wikipedia article on FFmpeg says, "License:  LGPL 2.1+, GPL 2+
Unredistributable if compiled with NVIDIA Performance Primitives." That 
comment has a footnote saying, "FFmpeg can be configured to make it 
proprietary and unredistributable software, because NVIDIA Performance 
Primitives, an optional external library, is proprietary software and 
cannot be distributed under the terms of the GPL."


             1.  If anyone has any information that contradicts this, I 
want to know -- especially I want a solid, reputable source that can be 
cited in that Wikipedia article.


             2.  Otherwise, this would seem to answer the question: You 
should read the LGPL and GPL and perhaps consult an attorney, but I 
think this means that a small company can bundle their proprietary 
software with FFMPEG, and distribute their device without paying a 
license fee to FFmpeg.  Of course, if the product is successful, one 
might expect that the small company donates to FFmpeg and may even pay 
some of their own people to help develop FFmpeg so it becomes a better 
product for everyone else in the future.
