DJI SDK uses FFmpeg as a static library (.so file). Our compiling processing is explained as follow:

The set-up : MacBook Pro Mid 2015 15-inch, running VMware Fusion Professional Version 8.5.6 (5234762), with image of ubuntu ubuntu-16.04.2-desktop-amd64.iso

• Edit the first line to match your NDK location.
• Find where TOOLCHAINS_VERSION was declared in the file and change it to your version. At this moment, DJI is using 4.9.
• Also change the PLATFORM_VERSION to the latest one that comes with your Android SDK. At this moment, DJI is using 21.
• To build the .so file of FFmpeg for Android, execute build_android.sh

To build the .so file of FFmpeg for iOS, please execute build_iOS.sh
