近期项目需要解析苹果的HLS流媒体协议，而FFmpeg从0.11.1“Happiness”版本开始，才增加了对HLS协议的支持。目前网上关于FFmpeg编译移植的文章有很多，但大多都是对旧版本的说明。新版本的源码对很多地方做了改动，包括一些变量名、常量名、函数名、函数参数、结构体等，所以在用旧版本的JNI接口时，需要相应地做出改动。这个编译移植工作确实花了本人不少时间，现在总结一下，希望能给到大家一些帮助。说明一点，本文阐述的不一定都正确，大家在编译过程中，难免会遇到各种各样的错误，可以提出来，一起讨论。
编译环境：Ubuntu 12.04、Android NDK r8
一、下载源码、新建工程
下载地址：http://ffmpeg.org/download.html ,下载最新ffmpeg-0.11.1压缩包。
在$NDK_HOME/samples/目录下（我的是/root/Develop/android-ndk-r8/samples/）创建一个FFMPEG-0.11目录，在里面新建一个jni目录，然后把ffmpeg源码解压放在jni里面，源码的文件夹重命名为libffmpeg，所以最后源码的路径是:
/root/Develop/android-ndk-r8/samples/FFMPEG-0.11/jni/libffmpeg
二、配置源代码
1. 创建config_common.sh脚本
在jni目录下创建一个config_common.sh，内容如下：
#!/bin/bash FFCONFIG_COMMON=' --enable-version3 --disable-gpl --disable-nonfree --disable-debug --disable-ffmpeg --disable-ffplay --disable-ffserver --disable-ffprobe --disable-encoders --disable-muxers --disable-devices --disable-protocols --enable-protocol=file --disable-swscale --disable-avfilter --enable-network --disable-avdevice --enable-parsers --disable-decoders --disable-demuxers --enable-demuxer=matroska --disable-demuxer=rm --disable-demuxer=avi --disable-demuxer=flv --disable-demuxer=mov --enable-demuxer=mp3 --enable-demuxer=mpegps --enable-demuxer=mpegvideo --enable-demuxer=asf --enable-decoder=aac --enable-decoder=ac3 --enable-decoder=dca --enable-decoder=flv --disable-decoder=h263 --disable-decoder=h264 --enable-decoder=svq3 --enable-decoder=amrnb --enable-decoder=nellymoser --enable-decoder=pcm_alaw --enable-decoder=pcm_dvd --enable-decoder=pcm_mulaw --enable-decoder=pcm_s16be --enable-decoder=pcm_s16le --enable-decoder=pcm_s16le_planar --enable-decoder=pcm_s24be --enable-decoder=pcm_s24daud --enable-decoder=pcm_s24le --enable-decoder=pcm_s32be --enable-decoder=pcm_s32le --enable-decoder=pcm_s8 --enable-decoder=pcm_u16be --enable-decoder=pcm_u16le --enable-decoder=pcm_u24be --enable-decoder=pcm_u24le --enable-decoder=pcm_u32be --enable-decoder=pcm_u32le --enable-decoder=atrac3 --enable-decoder=pcm_u8 --enable-decoder=sipr --enable-decoder=mjpeg --enable-decoder=mp1 --enable-decoder=mp2 --enable-decoder=mp3 --enable-decoder=tscc --enable-decoder=mpeg1video --enable-decoder=mpeg2video --enable-decoder=mpeg4 --enable-decoder=ra_144 --enable-decoder=ra_288 --enable-decoder=cook --enable-decoder=rv10 --enable-decoder=rv20 --enable-decoder=rv30 --enable-decoder=rv40 --enable-decoder=wmav1 --enable-decoder=wmav2 --enable-decoder=wmapro --disable-decoder=wmv1 --disable-decoder=wmv2 --disable-decoder=wmv3 --enable-decoder=vc1 --enable-decoder=msmpeg4v1 --enable-decoder=msmpeg4v2 --enable-decoder=msmpeg4v3 '
可以根据需要自行配置以上参数。
2. 创建config.sh脚本
在jni目录下创建一个config.sh，内容如下：
#!/bin/bash source config_common.sh /*这里执行上面的config_common.sh脚本*/ cd libffmpeg /*进入libffmpeg目录*/ PREBUILT=/root/Develop/android-ndk-r8/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86 PLATFORM=/root/Develop/android-ndk-r8/platforms/android-14/arch-arm ./configure --target-os=linux \ --arch=arm \ --enable-shared \ --enable-cross-compile \ --cc=$PREBUILT/bin/arm-linux-androideabi-gcc \ --cross-prefix=$PREBUILT/bin/arm-linux-androideabi- \ --strip=$PREBUILT/bin/arm-linux-androideabi-strip \ --extra-cflags="-fPIC -DANDROID" \ --extra-ldflags="-Wl,-T,$PREBUILT/arm-linux-androideabi/lib/ldscripts/armelf_linux_eabi.x -Wl,-rpath-link=$PLATFORM/usr/lib -L$PLATFORM/usr/lib -nostdlib $PREBUILT/lib/gcc/arm-linux-androideabi/4.4.3/crtbegin.o $PREBUILT/lib/gcc/arm-linux-androideabi/4.4.3/crtend.o -lc -lm -ldl" \ $FFCONFIG_COMMON cd .. /*返回jni目录*/ ndk-build clean
3. 执行config.sh脚本
然后打开终端，执行以下命令：
$chmod +x config.sh /*赋予config.sh执行权限*/
$./config.sh
$./config.sh
如果配置正确的话，显示出来的最后两行是这样的：
License:LGPL version 3 or later
Creating config.mak and config.h...
Creating config.mak and config.h...
若出现WARNING:/root/Develop/android-ndk-8/.............../arm-linux-androideabi-pkg-config not found, library detection may fail. 可忽略。
4. 修改config.h
进入jni/libffmpeg/目录，在刚刚生成的config.h中找到这句：
#define restrict restrict
因为Android的gcc并不认得restrict这个关键字，所以把它改写成：
#define restrict
如果需要联网的话，还需要将config.h中的以下定义置为1：
#define CONFIG_NETWORK 1
#define CONFIG_HTTP_PROTOCOL 1
#define CONFIG_HTTPPROXY_PROTOCOL 1
#define CONFIG_HTTPS_PROTOCOL 1
#define CONFIG_TCP_PROTOCOL 1
#define CONFIG_UDP_PROTOCOL 1
#define HAVE_STRUCT_SOCKADDR_STORAGE 1
#define HAVE_STRUCT_ADDRINFO 1
#define HAVE_SOCKLEN_T 1
#define HAVE_INET_ATON 0
#define CONFIG_HTTP_PROTOCOL 1
#define CONFIG_HTTPPROXY_PROTOCOL 1
#define CONFIG_HTTPS_PROTOCOL 1
#define CONFIG_TCP_PROTOCOL 1
#define CONFIG_UDP_PROTOCOL 1
#define HAVE_STRUCT_SOCKADDR_STORAGE 1
#define HAVE_STRUCT_ADDRINFO 1
#define HAVE_SOCKLEN_T 1
#define HAVE_INET_ATON 0
相应的，config.mak中也需要修改为：
CONFIG_NETWORK=yes
CONFIG_HTTP_PROTOCOL=yes
CONFIG_HTTPPROXY_PROTOCOL=yes
CONFIG_HTTPS_PROTOCOL=yes
CONFIG_TCP_PROTOCOL=yes
CONFIG_UDP_PROTOCOL=yes
HAVE_STRUCT_SOCKADDR_STORAGE=yes
HAVE_STRUCT_ADDRINFO=yes
HAVE_SOCKLEN_T=yes
!HAVE_INET_ATON=yes
CONFIG_HTTP_PROTOCOL=yes
CONFIG_HTTPPROXY_PROTOCOL=yes
CONFIG_HTTPS_PROTOCOL=yes
CONFIG_TCP_PROTOCOL=yes
CONFIG_UDP_PROTOCOL=yes
HAVE_STRUCT_SOCKADDR_STORAGE=yes
HAVE_STRUCT_ADDRINFO=yes
HAVE_SOCKLEN_T=yes
!HAVE_INET_ATON=yes
5. 修改libm.h文件
将/libavutil/libm.h中所有的static函数全部注释掉。
6. 修改Makefile文件
分別修改libavcodec、libavfilter、libavformat、libavutil、libpostproc和libswscale目录下的Makefile文件，将下面一句注释掉：
include $(SUBDIR)../config.mak
7. 新建av.mk脚本
在/jni/libffmpeg下建立一个脚本文件av.mk，內容如下：
# LOCAL_PATH is one of libavutil, libavcodec, libavformat, or libswscale
#include $(LOCAL_PATH)/../config-$(TARGET_ARCH).mak
include $(LOCAL_PATH)/../config.mak
OBJS :=
OBJS-yes :=
MMX-OBJS-yes :=
include $(LOCAL_PATH)/Makefile
ifdef ADDITION_INC
include $(ADDITION_INC)
endif
# collect objects
OBJS-$(HAVE_MMX) += $(MMX-OBJS-yes)
OBJS += $(OBJS-yes)
FFNAME := lib$(NAME)
FFLIBS := $(foreach,NAME,$(FFLIBS),lib$(NAME))
FFCFLAGS = -DHAVE_AV_CONFIG_H $(CFLAGS)
FFCFLAGS += -DTARGET_CONFIG=\"config-$(TARGET_ARCH).h\"
ALL_S_FILES := $(wildcard $(LOCAL_PATH)/$(TARGET_ARCH)/*.S)
ALL_S_FILES := $(addprefix $(TARGET_ARCH)/, $(notdir $(ALL_S_FILES)))
ifneq ($(ALL_S_FILES),)
ALL_S_OBJS := $(patsubst %.S,%.o,$(ALL_S_FILES))
C_OBJS := $(filter-out $(ALL_S_OBJS),$(OBJS))
S_OBJS := $(filter $(ALL_S_OBJS),$(OBJS))
else
C_OBJS := $(OBJS)
S_OBJS :=
endif
C_FILES := $(patsubst %.o,%.c,$(C_OBJS))
S_FILES := $(patsubst %.o,%.S,$(S_OBJS))
FFFILES := $(sort $(S_FILES)) $(sort $(C_FILES))
#include $(LOCAL_PATH)/../config-$(TARGET_ARCH).mak
include $(LOCAL_PATH)/../config.mak
OBJS :=
OBJS-yes :=
MMX-OBJS-yes :=
include $(LOCAL_PATH)/Makefile
ifdef ADDITION_INC
include $(ADDITION_INC)
endif
# collect objects
OBJS-$(HAVE_MMX) += $(MMX-OBJS-yes)
OBJS += $(OBJS-yes)
FFNAME := lib$(NAME)
FFLIBS := $(foreach,NAME,$(FFLIBS),lib$(NAME))
FFCFLAGS = -DHAVE_AV_CONFIG_H $(CFLAGS)
FFCFLAGS += -DTARGET_CONFIG=\"config-$(TARGET_ARCH).h\"
ALL_S_FILES := $(wildcard $(LOCAL_PATH)/$(TARGET_ARCH)/*.S)
ALL_S_FILES := $(addprefix $(TARGET_ARCH)/, $(notdir $(ALL_S_FILES)))
ifneq ($(ALL_S_FILES),)
ALL_S_OBJS := $(patsubst %.S,%.o,$(ALL_S_FILES))
C_OBJS := $(filter-out $(ALL_S_OBJS),$(OBJS))
S_OBJS := $(filter $(ALL_S_OBJS),$(OBJS))
else
C_OBJS := $(OBJS)
S_OBJS :=
endif
C_FILES := $(patsubst %.o,%.c,$(C_OBJS))
S_FILES := $(patsubst %.o,%.S,$(S_OBJS))
FFFILES := $(sort $(S_FILES)) $(sort $(C_FILES))
8. 新建Android.mk脚本
在jni目录下新建Android.mk，內容如下：
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES := ExportJNI.cpp ExportPlayer.cpp PacketQueue.cpp /*其中ExportJNI.cpp是我编写的JNI接口*/
LOCAL_STATIC_LIBRARIES := libavformat libavcodec libswscale libavutil libpostproc ffmpeg libsubtitle /*注意Libraries的顺序*/
LOCAL_MODULE := export /*最终生成libexport.so*/
LOCAL_ARM_MODE := arm
LOCAL_CFLAGS := -D__STDC_CONSTANT_MACROS -I$(LOCAL_PATH)/libffmpeg/ -I$(LOCAL_PATH)/libsubtitle/
LOCAL_LDLIBS := -llog
include $(BUILD_SHARED_LIBRARY)
include $(call all-makefiles-under,$(LOCAL_PATH))
include $(CLEAR_VARS)
LOCAL_SRC_FILES := ExportJNI.cpp ExportPlayer.cpp PacketQueue.cpp /*其中ExportJNI.cpp是我编写的JNI接口*/
LOCAL_STATIC_LIBRARIES := libavformat libavcodec libswscale libavutil libpostproc ffmpeg libsubtitle /*注意Libraries的顺序*/
LOCAL_MODULE := export /*最终生成libexport.so*/
LOCAL_ARM_MODE := arm
LOCAL_CFLAGS := -D__STDC_CONSTANT_MACROS -I$(LOCAL_PATH)/libffmpeg/ -I$(LOCAL_PATH)/libsubtitle/
LOCAL_LDLIBS := -llog
include $(BUILD_SHARED_LIBRARY)
include $(call all-makefiles-under,$(LOCAL_PATH))
在jni/libffmpeg目录下新建Android.mk：
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES := settings.c MyLog.cpp /*如果不需要打印输出等辅助功能，这行可删去*/
LOCAL_MODULE := ffmpeg
LOCAL_ARM_MODE := arm
include $(BUILD_STATIC_LIBRARY)
include $(call all-makefiles-under,$(LOCAL_PATH))
include $(CLEAR_VARS)
LOCAL_SRC_FILES := settings.c MyLog.cpp /*如果不需要打印输出等辅助功能，这行可删去*/
LOCAL_MODULE := ffmpeg
LOCAL_ARM_MODE := arm
include $(BUILD_STATIC_LIBRARY)
include $(call all-makefiles-under,$(LOCAL_PATH))
在jni/libffmpeg/libavformat目录下新建Android.mk：
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
include $(LOCAL_PATH)/../av.mk
LOCAL_SRC_FILES := $(FFFILES)
LOCAL_C_INCLUDES := \
$(LOCAL_PATH) \
$(LOCAL_PATH)/..
LOCAL_CFLAGS += $(FFCFLAGS)
LOCAL_CFLAGS += -include "string.h" -Dipv6mr_interface=ipv6mr_ifindex
LOCAL_LDLIBS := -lz
LOCAL_STATIC_LIBRARIES := $(FFLIBS)
LOCAL_MODULE := $(FFNAME)
LOCAL_ARM_MODE := arm
include $(BUILD_STATIC_LIBRARY)
include $(CLEAR_VARS)
include $(LOCAL_PATH)/../av.mk
LOCAL_SRC_FILES := $(FFFILES)
LOCAL_C_INCLUDES := \
$(LOCAL_PATH) \
$(LOCAL_PATH)/..
LOCAL_CFLAGS += $(FFCFLAGS)
LOCAL_CFLAGS += -include "string.h" -Dipv6mr_interface=ipv6mr_ifindex
LOCAL_LDLIBS := -lz
LOCAL_STATIC_LIBRARIES := $(FFLIBS)
LOCAL_MODULE := $(FFNAME)
LOCAL_ARM_MODE := arm
include $(BUILD_STATIC_LIBRARY)
在jni/libffmpeg/libavcodec目录下新建Android.mk：
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
ADDITION_INC := $(LOCAL_PATH)/arm/Makefile
include $(LOCAL_PATH)/../av.mk
ADDITION_INC :=
LOCAL_SRC_FILES := $(FFFILES)
LOCAL_C_INCLUDES := \
$(LOCAL_PATH) \
$(LOCAL_PATH)/..
LOCAL_CFLAGS += $(FFCFLAGS)
ifeq ($(TARGET_ARCH_ABI),armeabi)
LOCAL_CFLAGS += -DUSE_INT
endif
LOCAL_LDLIBS := -lz
LOCAL_STATIC_LIBRARIES := $(FFLIBS)
LOCAL_MODULE := $(FFNAME)
LOCAL_ARM_MODE := arm
include $(BUILD_STATIC_LIBRARY)
include $(CLEAR_VARS)
ADDITION_INC := $(LOCAL_PATH)/arm/Makefile
include $(LOCAL_PATH)/../av.mk
ADDITION_INC :=
LOCAL_SRC_FILES := $(FFFILES)
LOCAL_C_INCLUDES := \
$(LOCAL_PATH) \
$(LOCAL_PATH)/..
LOCAL_CFLAGS += $(FFCFLAGS)
ifeq ($(TARGET_ARCH_ABI),armeabi)
LOCAL_CFLAGS += -DUSE_INT
endif
LOCAL_LDLIBS := -lz
LOCAL_STATIC_LIBRARIES := $(FFLIBS)
LOCAL_MODULE := $(FFNAME)
LOCAL_ARM_MODE := arm
include $(BUILD_STATIC_LIBRARY)
在libavfilter、libavutil、libpostproc和libswscale目录下都分別新建Android.mk：
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
include$(LOCAL_PATH)/../av.mk
LOCAL_SRC_FILES:= $(FFFILES)
LOCAL_C_INCLUDES:= \
$(LOCAL_PATH) \
$(LOCAL_PATH)/..
LOCAL_CFLAGS+= $(FFCFLAGS)
LOCAL_STATIC_LIBRARIES:= $(FFLIBS)
LOCAL_MODULE:= $(FFNAME)
include$(BUILD_STATIC_LIBRARY)
include $(CLEAR_VARS)
include$(LOCAL_PATH)/../av.mk
LOCAL_SRC_FILES:= $(FFFILES)
LOCAL_C_INCLUDES:= \
$(LOCAL_PATH) \
$(LOCAL_PATH)/..
LOCAL_CFLAGS+= $(FFCFLAGS)
LOCAL_STATIC_LIBRARIES:= $(FFLIBS)
LOCAL_MODULE:= $(FFNAME)
include$(BUILD_STATIC_LIBRARY)
9. 新建Application.mk脚本
在jni目录下创建一个Application.mk，内容如下：
APP_STL := stlport_static
APP_ABI := armeabi
APP_ABI := armeabi
三、 NDK编译
在FFMPEG-0.11/下执行ndk-build：
$/
FFMPEG-0.11# ndk-build
编译过程需要十分钟左右，最后会在FFMPEG-0.11/obj/local/armeabi/目录下生成libavcodec.a、libavformat.a、libavutil.a、libffmpeg.a、libswscale.a和libpostproc.a以及libexport.so，在FFMPEG-0.11/libs/armeabi/目录下生成libexport.so。

请问下楼主有没有遇到这种情况：
libffmpeg/libavutil/float_dsp.c:132: undefined reference to `ff_float_dsp_init_arm'
我编译的时候，感觉libavutil/arm下的类好像都没编译，求帮忙。

写的很详细，博主能不能把ExportJNI.cpp 也共享下呢，想在Android 上转码，提高音量，唉，搞了好久

樓主你好，按你的步驟竟然發現出錯了，以下是錯誤訊息，麻煩您指導一下
/home/android-ndk-r8/build/core/build-binary.mk:41: *** target file `clean' has both : and :: entries. Stop.
/home/android-ndk-r8/build/core/build-binary.mk:41: *** target file `clean' has both : and :: entries. Stop.
这个问题我没有发现过哦，你再仔细检查一遍参数。。
lz，我也遇到了完全相同的问题，除了我是android-ndk-r8c之外。我是Linux下编译的。

楼主你好，之前那个问题已经解决了，是在 config.sh 里面的 每一行的最后有空格导致的。。
现在的问题是 你在第二大步的第八小步中提到：
8. 新建Android.mk脚本
在jni目录下新建Android.mk，內容如下：
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES := ExportJNI.cpp ExportPlayer.cpp PacketQueue.cpp /*其中ExportJNI.cpp是我编写的JNI接口*/
LOCAL_STATIC_LIBRARIES := libavformat libavcodec libswscale libavutil libpostproc ffmpeg libsubtitle /*注意Libraries的顺序*/
LOCAL_MODULE := export /*最终生成libexport.so*/
LOCAL_ARM_MODE := arm
LOCAL_CFLAGS := -D__STDC_CONSTANT_MACROS -I$(LOCAL_PATH)/libffmpeg/ -I$(LOCAL_PATH)/libsubtitle/
LOCAL_LDLIBS := -llog
include $(BUILD_SHARED_LIBRARY)
include $(call all-makefiles-under,$(LOCAL_PATH))
其中ExportJNI.cpp是我编写的JNI接口，这个能是怎么写的呢？能共享下么？没这个会编译失败还是？
