I wanted to use FFmpeg in an iOS app, but I ran into licensing issues—the FFmpeg wrapper [1] and FFmpeg itself [2] are both LGPL 2.1, which I didn't think you could use in an iOS app.

Since this project does exactly that, I took a second look and found a discussion on that specific use case [3]. It didn't quite clarify things, but it looks like it _might_ be legal to use FFmpeg in an app.
