Apple App Store neither Google Play Store allow Dynamic Linking. I know
TuneIn Radio uses FFmpeg as well, but they do not provide source code to
download. I want to do the same as TuneIn Radio does. What do I have to do?
I don't plan to modify FFmpeg, just use it. What I can do is provide the
FFmpeg source code I use, but I cannot provide object files of my compiled
app, so no re-linking of my app. It's a copyright app in those App stores
that's should not be copied.
