Ubuntu 14.04.2 移植FFmpeg 2.8.3 到Android平台

笔者生产环境是ubuntu14.04.2

一直都听说FFmpeg很强大很暴力

但一直都没时间研究沉淀

今天心血来潮,决定试试看

上正文

首先下载FFmpeg 2.8.3源代码

官方地址

Github地址

1.首先修改configure文件

去除后缀名之后的版本号

#修改前#SLIBNAME_WITH_MAJOR='$(SLIBNAME).$(LIBMAJOR)'#LIB_INSTALL_EXTRA_CMD='$$(RANLIB) "$(LIBDIR)/$(LIBNAME)"'#SLIB_INSTALL_NAME='$(SLIBNAME_WITH_VERSION)'#SLIB_INSTALL_LINKS='$(SLIBNAME_WITH_MAJOR) $(SLIBNAME)'#修改后SLIBNAME_WITH_MAJOR='$(SLIBPREF)$(FULLNAME)-$(LIBMAJOR)$(SLIBSUF)'LIB_INSTALL_EXTRA_CMD='$$(RANLIB)"$(LIBDIR)/$(LIBNAME)"'SLIB_INSTALL_NAME='$(SLIBNAME_WITH_MAJOR)'SLIB_INSTALL_LINKS='$(SLIBNAME)'

当然了可以写成一个Shell脚本librename.sh

dot="'"SLIBNAME_WITH_MAJOR=(LIBNAME_WITH_MAJOR=$dot'$(SLIBNAME).$(LIBMAJOR)'$dot)SLIBNAME_WITH_MAJOR_REP=(LIBNAME_WITH_MAJOR=$dot'$(SLIBPREF)$(FULLNAME)-$(LIBMAJOR)$(SLIBSUF)'$dot)SLIB_INSTALL_NAME=(SLIB_INSTALL_NAME=$dot'$(SLIBNAME_WITH_VERSION)'$dot)SLIB_INSTALL_NAME_REP=(SLIB_INSTALL_NAME=$dot'$(SLIBNAME_WITH_MAJOR)'$dot)SLIB_INSTALL_LINKS=(SLIB_INSTALL_LINKS=$dot'$(SLIBNAME_WITH_MAJOR)\s$(SLIBNAME)'$dot)SLIB_INSTALL_LINKS_REP=(SLIB_INSTALL_LINKS=$dot'$(SLIBNAME)'$dot)sed -i 's/'$SLIBNAME_WITH_MAJOR'/'$SLIBNAME_WITH_MAJOR_REP'/g' configuresed -i 's/'$SLIB_INSTALL_NAME'/'$SLIB_INSTALL_NAME_REP'/g' configuresed -i 's/'$SLIB_INSTALL_LINKS'/'$SLIB_INSTALL_LINKS_REP'/g' configure

2.编写脚本文件build.sh

NDK=/work/android-ndk-r10eSYSROOT=$NDK/platforms/android-9/arch-arm/  TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64    function build_one  {    ./configure \   --prefix=$PREFIX \   --enable-shared \   --disable-static \   --disable-yasm \   --disable-doc \   --disable-ffserver \   --enable-cross-compile \   --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \   --target-os=linux \   --arch=arm \   --sysroot=$SYSROOT \   --extra-cflags="-Os -fpic $ADDI_CFLAGS" \   --extra-ldflags="$ADDI_LDFLAGS" \   $ADDITIONAL_CONFIGURE_FLAG}  CPU=arm  PREFIX=~/ffmpeg/$CPU  ADDI_CFLAGS="-marm"  build_one  

注意NDK,SYSROOT,TOOLCHAIN换成自己本机的地址

添加build.sh的权限

chmod -R 777 build.sh

执行

./build.sh

如果出现

WARNING: /work/android-ndk-r10e/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi-pkg-config not found, library detection may fail.

可以忽略

然后执行

makemake install

接着在目录

~/android/arm

就有我们需要的文件
