<div dir="ltr"><div>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.</div><div><br></div><div>I found this question <a href="http://video.stackexchange.com/questions/14802/can-i-use-ffmpeg-in-a-commercial-product">http://video.stackexchange.com/questions/14802/can-i-use-ffmpeg-in-a-commercial-product</a> </div><div>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.</div><div><br></div><div>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.</div><div><br></div><div>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.

There is AVOutputFormat->codec_tag but<br>
you are to some degree expected to<br>
know what you put into a container.<br>
<br>
Please explain your exact usecase.<br>
