repo init --repo-url ssh://[email protected]/tools/repo -u ssh://10.10.10.29:29418/android/platform/manifest -b rk33/mid/8.0/develop -m rk3328_box.xml//初始化repo

repo sync  //下載程式碼

//以上下載了ffplayer的工程環境

2.編譯環境
按照網址上的方法分別編譯uboot、kernel、android

uboot：
[email protected]-server3:~/3328_8.1/u-boot$ make ARCHV=aarch64 rk3328_box_defconfig
 
[email protected]-server3:~/3328_8.1/u-boot$ ./mkv8.sh

kernel：
[email protected]-server3:~/3328_8.1/kernel$ make ARCH=arm64 rockchip_defconfig
[email protected]-server3:~/3328_8.1/kernel$ make ARCH=arm64  rk3328-evb-android.img -j8

android：
[email protected]-server3:~/3328_8.1$ source javaenv.
 
sh   //用於修改jdk版本
[email protected]-server3:~/3328_8.1$ mm -j8   //編譯

[email protected]-server3:~/3328_8.1/frameworks/av/media$   git clone ssh://[email protected]:29418/libffplayer
//注意路徑   此時把所有的下載下來了，但看不見程式碼

[email protected]-server3:~/3328_8.1/frameworks/av/media/libffplayer$  git branch -a   //檢視分支
 

[email protected]-server3:~/3328_8.1/frameworks/av/media/libffplayer$   git checkout rkffplayer-2015  
 //切換到rkffplayer-2015分支，此時可以看到程式碼

//因為ffplayer要連結到ffmpeg，所以還要下載ffmpeg的程式碼
[email protected]-server3:~/3328_8.1/external$ git clone ssh://[email protected]:29418/ffmpeg
[email protected]-server3:~/3328_8.1/external/ffmpeg$ git branch -a
[email protected]-server3:~/3328_8.1/external/ffmpeg$ git checkout ffmpeg-12-11-04

總結：repo init + repo sync 下載工程環境
編譯uboot、kernel、android
git clone 下載libffplayer、ffmpeg程式碼
（不要弄錯先後順序）

遇到的問題：
編譯android時，出現如下問題：
Failed to contact Jack server: Problem reading /home/xlh/.jack-server/client.pem. Try ‘jack-diagnose’
Failed to contact Jack server: Problem reading /home/xlh/.jack-server/client.pem. Try ‘jack-diagnose’
原因jack編譯器不執行多個使用者同時編譯，要對~/.jack-settings和~/.jack-server/config.properties檔案同時修改埠號。
解決方法：

prebuilts/sdk/tools/jack-diagnose   //執行該命令會顯示錯誤情況

[email protected]-server3:~$ vim .jack-settings   
[email protected]-server3:~/.jack-server$ vim config.properties  //若沒有該檔案自己建立
[email protected]-server3:~/.jack-server$ chmod 0600 config.properties   //設定許可權

[email protected]:~$ cat .jack-settings
# Server settings
SERVER_HOST=localhost
SERVER_PORT_SERVICE=8074
SERVER_PORT_ADMIN=8075

# Internal, do not touch
SETTING_VERSION=4

config.properties檔案如下：
