Live555在Amlogic系列芯片上的移植

    近期因为工作的原因，需要用到Live555，之前在工作之余玩过它，但没有记录移植过程，这次在往Amlogic系列平台上移植的时候，遇到了些小麻烦，所以这次决定记录下这个过程。

    一，获取Live555的最新源码。地址：http://www.live555.com/liveMedia/public/live.2015.04.22.tar.gz。（这个代码的日期会随时更新，这是我下载时最近的版本）。

    二、解压源码并把代码copy到Amlogic系统平台的external目录下，并命名为Live555。修改整个Live555目录的文件权限属性，因为有些文件是只有读权限的，我们没办法修改。

    三、在Live555目录下和mediaServer目录下分别增加一个Android.mk文件。

    四、填写如下内容：

    1.***/live555/Android.mk

LOCAL_SRC_FILES := \

$(usageenv_src_files)

LOCAL_MODULE := liblive555
LOCAL_ARM_MODE := arm
LOCAL_PRELINK_MODULE := false
LOCAL_MODULE_TAGS := optional

LOCAL_CPPFLAGS := \
-DNO_SSTREAM \

-lgnustl_static \
-lsupc++

include $(BUILD_SHARED_LIBRARY)

#build mediaServer
include $(LIVE_PATH)/mediaServer/Android.mk

其中LOCAL_CPPFLAGS：

-DNO_SSTREAM --解决“fatal error: sstream: No such file or directory”

-fexceptions -- 解决“error: exception handling disabled, use -fexceptions to enable”

-DXLOCALE_NOT_USED -- 解决"xlocale.h: No such file or directory"

如果出现：

error: undefined reference to '__cxa_end_cleanup'

error: undefined reference to '__gxx_personality_v0'

等类似错误提示，增加：

NDK_PATH := $(LIVE_PATH)/../../prebuilts/ndk/8/sources/cxx-stl/gnu-libstdc++/libs/armeabi-v7a
LOCAL_LDFLAGS := \
<span>	</span>-L$(NDK_PATH) \
-lgnustl_static \
-lsupc++

其中NDK_PATH 是你平台中NDK的路径，根据自己的实际情况修改。

2.***/live555/mediaServer/Android.mk

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

LOCAL_MODULE:= mediaServer
LOCAL_PRELINK_MODULE := false

LOCAL_MODULE_TAGS := optional

LOCAL_SRC_FILES := \
live555MediaServer.cpp \
DynamicRTSPServer.cpp

LOCAL_SHARED_LIBRARIES := liblive555

LOCAL_C_INCLUDES := \
$(LOCAL_PATH) \
$(LOCAL_PATH)/../ \
$(LOCAL_PATH)/../BasicUsageEnvironment \
$(LOCAL_PATH)/../BasicUsageEnvironment/include \
$(LOCAL_PATH)/../groupsock \
$(LOCAL_PATH)/../groupsock/include \
$(LOCAL_PATH)/../liveMedia \
$(LOCAL_PATH)/../liveMedia/include \
$(LOCAL_PATH)/../UsageEnvironment \
$(LOCAL_PATH)/../UsageEnvironment/include

五、进入Live555主目录，使用mm -B编译。

    看到这两句话就表示编译成功了：

Install: out/target/product/***/system/lib/liblive555.so

Install: out/target/product/***/system/bin/mediaServer

六、把liblive555.so copy到测试板中的/system/lib目录下，修改可读写权限，并把mediaServer copy到如：/data/tmp目录下。

七、执行./mediaServer

version 0.87 (LIVE555 Streaming Media library version 2015.04.16).
Play streams from this server using the URL
rtsp://192.168.0.101/<filename>
where <filename> is a file present in the current directory.
Each file's type is inferred from its name suffix:
".264" => a H.264 Video Elementary Stream file
".265" => a H.265 Video Elementary Stream file
".aac" => an AAC Audio (ADTS format) file
".ac3" => an AC-3 Audio file
".amr" => an AMR Audio file
".dv" => a DV Video file
".m4e" => a MPEG-4 Video Elementary Stream file
".mkv" => a Matroska audio+video+(optional)subtitles file
".mp3" => a MPEG-1 or 2 Audio file
".mpg" => a MPEG-1 or 2 Program Stream (audio+video) file
".ogg" or ".ogv" or ".opus" => an Ogg audio and/or video file
".ts" => a MPEG Transport Stream file
(a ".tsx" index file - if present - provides server 'trick play' support)
".vob" => a VOB (MPEG-2 video with AC-3 audio) file
".wav" => a WAV Audio file
".webm" => a WebM audio(Vorbis)+video(VP8) file
See http://www.live555.com/mediaServer/ for additional documentation.
(We use port 80 for optional RTSP-over-HTTP tunneling, or for HTTP live streaming (for indexed Transport Stream files only).)
