is it legal to use FFmpeg?
here is the url of FFmpeg's License and Legal Considerations:
http://ffmpeg.mplayerhq.hu/legal.html
In our project,we can assure that we only dynamicly link to the lpgled part
of FFmpeg.Is it legal to apply FFmpeg?
In the license faq of FFmpeg,it metions that it may involve with patent
algorithm but he can't be sure.
we apply libavcodec or libavformat in our project.in the general faq of
FFmpeg it says:
4.2 Integrating libavcodec or libavformat in your
program<http://ffmpeg.mplayerhq.hu/general.html#TOC22>
You can integrate all the source code of the libraries to link them
statically to avoid any version problem. All you need is to provide a
'config.mak' and a 'config.h' in the parent directory. See the defines
generated by ./configure to understand what is needed.
You can use libavcodec or libavformat in your commercial program, but *any
patch you make must be published*. The best way to proceed is to send your
patches to the FFmpeg mailing list.
here is the url of the general faq:http://ffmpeg.mplayerhq.hu/general.html

"Therefore,

But it was said we can dynamic link the code under LGPL-licensed before.
Is the ruler changed?

GNU LGPLThe LGPL is ineligible primarily due to the restrictions it places
on larger works, violating the third license criterion. Therefore,
LGPL-licensed works must not be included in Apache products. i guess it's
end of story.We can't use ffmpeg and must find a substitute.

# Contributions should be licensed under the LGPL 2.1, including an "or any later version" clause, or the MIT license. GPL 2
including an "or any later version" clause is also acceptable, but LGPL is preferred.
Wow. That's fairly ambiguous.
I don't know how this is going to pan out, but thought I should pass on the
relevant quotation.
Shipping LGPL isn't allowed, but as an /optional/ dependency it's possible
for projects to offer support to it.
