FFmpeg 移植 Android

阅读更多

 

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-demuxer=mpegps
	--enable-demuxer=mpegvideo
	--enable-demuxer=asf
	--enable-decoder=aac

	--enable-decoder=flv
	--disable-decoder=h263
	--disable-decoder=h264
	--enable-decoder=svq3

	--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
  

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...

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

 

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
  

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))
  

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))

 

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))

  
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)
   

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)
  

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)
  

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

 

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。

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?
