rtmp编译so

环境：

win7 、ndk-r10e

1 下载rtmp源码。

$ git clone git://git.ffmpeg.org/rtmpdump

生成rtmpdump目录，其目录下文件：

2 配置

将除librtmp目录的文件删除，创建jni文件夹，将librtmp文件夹拷入jni目录。由于librtmp依赖于openssl，所以我将编译好的libssl.so和libcrypto.so拷入该目录下。创建Android.mk文件和Application.mk文件。

Application.mk内容

APP_ABI  :=  armeabi-v7a

Android.mk内容

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

include $(CLEAR_VARS)
LOCAL_MODULE    := crypto
LOCAL_SRC_FILES := libcrypto.so
include $(PREBUILT_SHARED_LIBRARY)
###########################################
include $(CLEAR_VARS)
LOCAL_MODULE    := ssl
LOCAL_SRC_FILES := libssl.so
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include/openssl
include $(PREBUILT_SHARED_LIBRARY)
###########################################

include $(CLEAR_VARS)

LOCAL_SRC_FILES:= \
		librtmp/amf.c      \
		librtmp/hashswf.c  \
		librtmp/log.c      \
		librtmp/parseurl.c \
		librtmp/rtmp.c

LOCAL_LDLIBS    += -lm -llog -lz
LOCAL_CFLAGS +=  -D__STDC_CONSTANT_MACROS

LOCAL_C_INCLUDES :=                    		\
		$(LOCAL_PATH)                   \
		$(LOCAL_PATH)/include

LOCAL_MODULE:= librtmp

LOCAL_STATIC_LIBRARIES := \
			crypto \
			ssl


LOCAL_MODULE_TAGS:= optional

include $(BUILD_SHARED_LIBRARY)

整体目录：

3 进入到工程目录下编译

ndk-build

在rtmpdump\libs\armeabi-v7a目录下生成三个so
