Comment (by fabienst):

 Attached also a sample code that you can build yourself for android:
 test.c


 Building for arm64
 {{{
 $ANDROID_NDK_ROOT/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-
 android26-clang \
   test.c -I./libs.prebuilt/ffmpeg-4.4/include/
 -L$ANDROID_NDK_ROOT/toolchains/llvm/prebuilt/linux-
 x86_64/sysroot/usr/lib/aarch64-linux-android/26/ -llog
 -L./libs.prebuilt/ffmpeg-4.4/lib/arm64-v8a -lswscale -lavutil -o arm64.out
 }}}

 Running on arm64 doesn't crash
 {{{
 adb ./libs.prebuilt/ffmpeg-4.4/lib/arm64-v8a/libavutil.so
 ./libs.prebuilt/ffmpeg-4.4/lib/arm64-v8a/libswscale.so input output
 arm64.out /data/local/tmp
 adb shell
 cd /data/local/tmp
 LD_LIBRARY_PATH=. ./arm8.out
 }}}

 Building for x86_64

 Running on x86_64 does crash
