External Libraries

This project contains source code of FFmpeg and the following external libraries. MobileFFmpeg top level build scripts (android.sh, ios.sh) automatically compile these libraries based on build options.

Additionally, there are libraries with GPL license which are also supported by the top level build scripts. Their source code is not included in the repository and downloaded when enabled. If any of them is enabled MobileFFmpeg is subject to GPL v3.0 license.
