Sorry, Could you tell me which way do you compile, ndk-build or CMake？And you can describe your configuration of ffmpeg build in detail .

[mansiJspaceo]

yeah sure.. with ndk-build

for build ffmpeg-invoke.so file follow this artical https://juejin.im/post/5d440504f265da03b6388ed2

ffmpeg version:- 4.2.2 ndk Version:- NDK-r19c

only problem in build ffmpeg-invoke.so file

Thank you in Adavance

In fact compiling armeabi-v7a is enough, but using the latest version of ndk to compile arm64-v8a will give an error. I used ndk-14b to compile successfully, you can try it.
