【ffmpeg学习记录】ndk-r10d编译ffmpeg-2.6

roman10写过一篇很详细的使用ndk编译ffmepg的教程，本文仅在此文的基础上稍作修改使其能顺利编译ffmpeg-2.6版本。

前面两步没啥好说的，直接看第三步，把ndk的路径修改为你自己的路径，注意./configure这段，要把其中的空行给删掉：

./configure \
    --prefix=$PREFIX \
    --enable-shared \
    --disable-static \
    --disable-doc \
    --disable-ffmpeg \
    --disable-ffplay \
    --disable-ffprobe \
    --disable-ffserver \
    --disable-avdevice \
    --disable-doc \
    --disable-symver \
    --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
    --target-os=linux \
    --arch=arm \
    --enable-cross-compile \
    --sysroot=$SYSROOT \
    --extra-cflags="-Os -fpic $ADDI_CFLAGS" \
    --extra-ldflags="$ADDI_LDFLAGS" \
    $ADDITIONAL_CONFIGURE_FLAG

然后第五步，注意到原文评论中很多人指出的一个拼写错误，把swresmaple误输入为wsresample，最后把里面出现的所有libxxx-version.so中的version都改成编译生成的版本，如2.5.3编译的avcodec库就是libavcodec-56.so

LOCAL_PATH:= $(call my-dir)

 

include $(CLEAR_VARS)

LOCAL_MODULE:= libavcodec

LOCAL_SRC_FILES:= lib/libavcodec-56.so

LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include

include $(PREBUILT_SHARED_LIBRARY)

 

include $(CLEAR_VARS)

LOCAL_MODULE:= libavformat

LOCAL_SRC_FILES:= lib/libavformat-56.so

LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include

include $(PREBUILT_SHARED_LIBRARY)

 

include $(CLEAR_VARS)

LOCAL_MODULE:= libswscale

LOCAL_SRC_FILES:= lib/libswscale-3.so

LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include

include $(PREBUILT_SHARED_LIBRARY)

 

include $(CLEAR_VARS)

LOCAL_MODULE:= libavutil

LOCAL_SRC_FILES:= lib/libavutil-54.so

LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include

include $(PREBUILT_SHARED_LIBRARY)

 

include $(CLEAR_VARS)

LOCAL_MODULE:= libavfilter

LOCAL_SRC_FILES:= lib/libavfilter-5.so

LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include

include $(PREBUILT_SHARED_LIBRARY)

 

include $(CLEAR_VARS)

LOCAL_MODULE:= libswresample

LOCAL_SRC_FILES:= lib/libswresample-1.so

LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include

include $(PREBUILT_SHARED_LIBRARY)

其余的照着原文的步骤来就可以了
