一、記錄
Ubuntu 14 64位
ndk r10b
librtmp 2.4
speex 1.2rc2
ffmpeg 2.8.1
二、編譯
1、編譯librtmp
下載地址：http://rtmpdump.mplayerhq.hu/
Android.mk
# This is the Android makefile for librtmp
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES := \
amf.c \
hashswf.c \
log.c \
parseurl.c \
rtmp.c
LOCAL_CFLAGS += -DNO_CRYPTO
LOCAL_MODULE := librtmp
LOCAL_MODULE_TAGS := optional
include $(BUILD_STATIC_LIBRARY)
Application.mk
# The ARMv7 is significanly faster due to the use of the hardware FPU
APP_ABI := armeabi-v7a
APP_MODULES := librtmp
APP_PLATFORM := android-14
2、編譯speex
下載地址：http://www.speex.org/downloads/
Android.mk
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := libspeex
LOCAL_CFLAGS = -DFIXED_POINT -DUSE_KISS_FFT -DEXPORT="" -UHAVE_CONFIG_H
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include
LOCAL_SRC_FILES := \
./libspeex/bits.c \
./libspeex/cb_search.c \
./libspeex/exc_10_16_table.c \
./libspeex/exc_10_32_table.c \

./libspeex/window.c
include $(BUILD_STATIC_LIBRARY)
Application.mk
APP_ABI := armeabi-v7a
APP_MODULES := libspeex
APP_PLATFORM := android-14
3、編譯ffmpeg
下載命令：git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg
（1）修改configure
#enabled librtmp && require_pkg_config librtmp librtmp/rtmp.h RTMP_Socket
enabled librtmp && require librtmp librtmp/rtmp.h RTMP_Socket -lrtmp
#enabled libspeex && require_pkg_config speex speex/speex.h speex_decoder_init -lspeex
enabled libspeex && require libspeex speex/speex.h speex_decoder_init -lspeex
（2）腳本

三、問題總結
1、Android工程添加librtmp.a後，提示各種unreference RTMP_XXXX
解決：最早使用gcc編譯librtmp，直接在rtmpdump/librtmp下make，nm查看所有unreference的函數都有，最後是更改了ffmpeg編譯腳本，configure報錯“librtmp not found”，查看了config.log，發現提示ld path/to/librtmp.a incompatible ...，最終改爲ndk編譯librtmp；
注：speex通librtmp
