1、廢話linux

最近學習,第一步就是編譯.咱們須要編譯FFmpag,x264,fdk_aac，下面是x264,網上說的不少都是幾百年前的，我親測完美可用android

仍是那句話我能力有限，可是我但願我寫的東西可以讓更多的人可以接受.我也是剛剛接觸.作一個記錄，也但願可以對其餘人有好處.
聯繫我能夠直接評論，也能夠加我QQ：2519687025git

2、乾貨

準備：1.fdk_aac的源碼 git clone https://android.googlesource.com/platform/external/aaceclipse

3.須要下載cmake 直接在cmd裏面就能夠了,以前的FFmpeg和x264都是cygwin裏面的.如今不用.須要設置cmake環境變量,加入到path裏面ide

4.編譯腳本.這個腳本本身去理解吧.我也是隻知其一;不知其二--腳本名稱：CMakeLists.txt學習

    endif ()

    find_path ( TOOLCHAIN_ROOT bin PATHS ${ANDROID_NDK_ROOT}/toolchains/arm-linux-androideabi-${NDK_TOOLCHAIN_VERSION}/prebuilt /* )

endforeach ()

add_library ( fdk-aac STATIC
    ${SOURCE_FILES} )

install ( TARGETS fdk-aac
    ARCHIVE DESTINATION ${ARCHIVE_INSTALL_DIR} )

3、編譯ui

這個的編譯相對簡單，只要下載cmake就能夠了.直接cmake就能夠了.google

1 .定位到編譯目錄

2.執行cmake 命令
cmake -G "MinGW Makefiles" -DCMAKE_SYSTEM_NAME=Andr
oid -DFDK_AAC_SOURCE_DIR="E:/soft/source/fdk_aac/aac" E:\qupai_code_eclipse\code
\ThirdParty\Build\fdk-aac -DCMAKE_MAKE_PROGRAM=E:\android-ndk-r9c\prebuilt\windo
ws\bin\make.exeidea

3 .cmake --bulid . -- -j8

注意：DFDK_AAC_SOURCE_DIR="你的fdk_aac的源碼地址" spa

E:\qupai_code_eclipse\code\ThirdParty\Build\fdk-aac ----這裏是你的CMakeLists.txt地址

DCMAKE_MAKE_PROGRAM=NDK的make地址
