7. x264編譯流程
7.1 原始碼
x264原始碼下載指令:“svn co svn://svn.videolan.org/x264/trunk x264”
7.2 編譯
1.
至/home/userName/,編輯.bash_profile以加入cross compiler路徑,加入以下:“PATH=/opt/crosstool/gcc-4.1.0-glib-2.3.2/arm-xscale-linux-gnu/ arm-xscale-linux-gnu/bin/:$PATH”、“export PATH”
2.
接著重新載入bash,輸入“gcc -v”,如果Target顯示出:“arm-xscale-linux-gnu”之類的信息,代表路徑正確設定
3.
4.
進入x264目錄下,執行“./configure”生成config.mak檔
5.
此時的平台設定為x86的,必須改為arm的,開啟config.mak,改寫以下:(ARCH=ARM)、(CFLAGS=-O3 -ffast-math -Wall -I. -DARCH_ARM -DSYS_LINUX -s -fomit-frame-pointer)、(CONFIGURE_ARGS= '--disable-pthread')、(AS=as)(ASFLAGS=)
6.
7.
即可編譯出x264檔,此檔案只能在ARM的平台上執行
8.
以下為這次專題使用的參數“x264 -r 1 -I 250 -i 26 -b 0 -q 20 -A all --me dia --subme 1 -t 2 --progress -o test.264 foreman_qcif_400.yuv 176x144”為了方便執行可以存成“fileName.sh”,到時要執行x264編碼時只需輸入“sh fileName.sh”即可
