服务器评测
环境:Ubuntu 16.04
交叉编译器版本:4.8.3
依赖x264,lame
x264:
1.wget ftp://ftp.videolan.org/pub/x264/snapshots/last_stable_x264.tar.bz2
2.tar xvf last_stable_x264.tar.bz2
3.cd x264-snapshot-20170903-2245-stable
4.export CC=arm-linux-gnueabi-gcc
5.export AR=arm-linux-gnueabi-ar
6.mkdir build
7.cd build
8. ../configure –enable-static –enable-shared –disable-asm –prefix=$PWD/__install –host=arm-linux-gnueabi
9.make
10.make install
lame:
1.wget https://sourceforge.net/projects/lame/files/lame/3.99/lame-3.99.5.tar.gz
2.tar xvf lame-3.99.5.tar.gz
3.cd lame-3.99.5
4.mkdir build
5.cd build
6. ../configure –prefix=$PWD/__install –host=arm-linux-gnueabi
7.make
8.make install
ffmpeg:
1.wget www.ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
2. tar xvf ffmpeg-snapshot.tar.bz2
3.cd ffmpeg
4.mkdir build
5.cd build
6. ../configure –cross-prefix=/opt/x86-arm/arm-linux/bin/arm-linux-gnueabi- –disable-asm –enable-static –arch=arm –target-os=linux –prefix=$PWD/_install –disable-x86asm –enable-gpl –enable-libx264 –enable-nonfree –enable-cross-compile –extra-cflags=-I/home/jello/x264-snapshot-20170903-2245-stable/build/_install/include –extra-ldflags=-L/home/jello/x264-snapshot-20170903-2245-stable/build/_install/lib –extra-libs=-ldl
7.进过步骤6在当前目录下有ffbuild/config.mak,那么修改此文件
文件中有以下四处需要修改
1.
CFLAGS= -I/home/jello/x264-snapshot-20170903-2245-stable/build/_install/include -march=armv5te -std=c11 -fomit-frame-pointer -marm -pthread -g -Wdeclaration-after-statement -Wall -Wdisabled-optimization -Wpointer-arith -Wredundant-decls -Wwrite-strings -Wtype-limits -Wundef -Wmissing-prototypes -Wno-pointer-to-int-cast -Wstrict-prototypes -Wempty-body -Wno-parentheses -Wno-switch -Wno-format-zero-length -Wno-pointer-sign -O3 -fno-math-errno -fno-signed-zeros -fno-tree-vectorize -Werror=format-security -Werror=implicit-function-declaration -Werror=missing-prototypes -Werror=return-type -Werror=vla -Wformat -Wno-maybe-uninitialized
2.
ASFLAGS= -I/home/jello/x264-snapshot-20170903-2245-stable/build/_install/include -march=armv5te -g
3.
LDFLAGS= -L/home/jello/x264-snapshot-20170903-2245-stable/build/_install/lib -march=armv5te -Wl,–as-needed -Wl,-z,noexecstack -Wl,–warn-common -Wl,-rpath-link=libpostproc:libswresample:libswscale:libavfilter:libavdevice:libavformat:libavcodec:libavutil:libavresample
4.EXTRALIBS=-lx264 -lm -pthread -pthread -lrt -ldl
将以上四项改动如下:
1.
CFLAGS= -I/home/jello/x264-snapshot-20170903-2245-stable/build/_install/include -I/home/jello/lame-3.99.5/build/_install/include/lame -march=armv5te -std=c11 -fomit-frame-pointer -marm -pthread -g -Wdeclaration-after-statement -Wall -Wdisabled-optimization -Wpointer-arith -Wredundant-decls -Wwrite-strings -Wtype-limits -Wundef -Wmissing-prototypes -Wno-pointer-to-int-cast -Wstrict-prototypes -Wempty-body -Wno-parentheses -Wno-switch -Wno-format-zero-length -Wno-pointer-sign -O3 -fno-math-errno -fno-signed-zeros -fno-tree-vectorize -Werror=format-security -Werror=implicit-function-declaration -Werror=missing-prototypes -Werror=return-type -Werror=vla -Wformat -Wno-maybe-uninitialized
2.
ASFLAGS= -I/home/jello/x264-snapshot-20170903-2245-stable/build/_install/include -I/home/jello/lame-3.99.5/build/_install/include/lame -march=armv5te -g
3.
LDFLAGS= -L/home/jello/x264-snapshot-20170903-2245-stable/build/_install/lib -L/home/jello/lame-3.99.5/build/_install/lib -march=armv5te -Wl,–as-needed -Wl,-z,noexecstack -Wl,–warn-common -Wl,-rpath-link=libpostproc:libswresample:libswscale:libavfilter:libavdevice:libavformat:libavcodec:libavutil:libavresample
4.EXTRALIBS=-lx264 -lm -pthread -pthread -lrt -ldl -lmp3lame
8.make
9.make install
