CANNOT LINK EXECUTABLE "ffmpeg" : library "libavdevice.so" not found

When I integrate the lib android-ffmpeg to my project ( I compile the file ffmpeg ,ffprobe myself whith ndk-r20 and ffmpeg-4.2.1 ), and then run the project, it got an error:

D/FFmpeg: Build.SUPPORTED_ABI : arm64-v8a
D/FFmpeg: ffmpeg is ready!
D/FFmpeg: Build.SUPPORTED_ABI : arm64-v8a

i have the library "libavdevice.so", i don't know why it happens. How to solve it?

I used file ffmpeg,ffprobe from your project, then it works well. But i don't know how to compile these files, in your project, the size of file ffmpeg and ffprobe nearly 20MB, when i compile it myself, it is just 200KB, can you tell me how you compile it please?
