[Libav-user] enumerating codec_tags

[Majid Poureftekhari]

I'm trying to make an editing app which I need to use FFmpeg libraries in
it. I need to know Which libraries of FFmpeg are not allowed to use in a
free app with ads in it? Because I should build a copy of FFmpeg based on
allowance of use of FFmpeg libraries. I couldn't find any clear explanation
of what libraries of FFmpeg we could use in a free app with ads in it.

I found this question
http://video.stackexchange.com/questions/14802/can-i-use-ffmpeg-in-a-commercial-product

which helped me to find out there is nonfree or version3 or gpl libraries
that are exist in a regular builds of FFmpeg that are important to pay
attention to.

But mentioned question talks about commercial applications not free ones.
And my question is does this three kind of libraries (nonfree,version3,gpl)
are exactly those which we could not use in a free app too? I mean license
policy for free apps are complicated and further more I don't know if an
app with ads in it is free or commercial.

I'm asking this question from developers who have used FFmpeg libraries in
their commercial or non-commercial applications or anyone who knows how to
use FFmpeg librarie with their complicated licenses not violated. Thanks
