Android集成RTMPDump实现推流

一.集成RTMPDump

  RTMPDump

源码地址： http://rtmpdump.mplayerhq.hu/

Git地址：
git clone git://git.ffmpeg.org/rtmpdump

二.集成到AS中

    1、直接拷贝：librtmp源码到cpp中

2、设置不适用OpenSSL
set(CMAKE_C_FLAGS “${CMAKE_C_FLAGS} -DNO_CRYPTO”)

3、加入rtmp源码编译
src/main/cpp/librtmp/amf.c
src/main/cpp/librtmp/hashswf.c
src/main/cpp/librtmp/log.c
src/main/cpp/librtmp/parseurl.c
src/main/cpp/librtmp/rtmp.c

三.推流图解如下

四.推流native代码示例
