I tried to compile ffmpeg for android on Mac, but it does not work for me.
#!/bin/bash

make clean all
make

}

build_one
I also give execute permission via chmod +x build_script.sh
I tried ffmpeg 4.1
and 4.0.3
but both are not work and same error reason.
I also tried on android-21
and android-18

Is there any tools/Applications or libraries I have to additionally install for compiling? I'm confused.... (THIS QUESTION IS MAY DUPLICATE BUT NONE OF SOLUTION WAS WORKED FOR ME)
EDIT To clarify my system environment.
EDIT I also tried ffmpeg version 3.3.9
but it does not work either.
You can use wrappers https://github.com/WritingMinds/ffmpeg-android if you want to use most of the command. It will increase the size of apk.
I also tried to compile it and after several attempts, I compiled my own one. But it is hard to integrate as well. I used below tutorials to compile it.
But I just wanted to tell, use FFmpeg wrapper for it if u don't consider the size of apk. There is not the considerable gain of performance in own compiled FFmpeg. Use above mentioned wrapper u want. It works well. If u more enthusiastic about compile and integrate your own FFmpeg, try above tutorials.
I was installed NDK through Android Studio and I think it was the problem, so I downloaded Android NDK manually and now I can configure and run the makefile.
Wait! Not done yet. When I ran makefile with latest stable NDK (r16b), it says:
./libavutil/common.h:33:19: fatal error: errno.h: No such file or directory
According to this document , so I tried using NDK r15c
and it finally works for me.
To summarize how I solve this problem : Manually install NDK r15c and DON'T FORGET update your shell script file!
Hope this help!!
