android_ffmpeg compile

ffmpeg:
https://ffmpeg.org/download.html

------------------------------------------------------
build ffmpeg on linux:
https://juejin.im/post/5d831333f265da03c61e8a28

ffmpeg-4.1.3 -> 4.1.5

Ndk r17c -> r21b

失敗

利用linux server(82.225), 製作xxx.sh檔 並執行,

主要注意:

cc& cxx 設定為clang & clang++

--prefix 設為$(pwd)/android/armv8-a (or armv7-a or x86 or x86-64)

Cflags 設定在各abi不同

1.

build_android

    --cc=$CC

    --cxx=$CXX

後面沒 “\”

2.

X86 or x86-64 => build_android =>新增 --disable-x86asm

3.

Gcc 改為 clang
