nginx-rtmp-module和ffmpeg搭建实时HLS切片

eecdc

1.rtmp服务器

nginx+pcre+zlib+openssl+nginx-rtmp-module

./configure \

--prefix=/usr/local/nginx \

--sbin-path=/usr/local/nginx/nginx \

--conf-path=/usr/local/nginx/nginx.conf \

--pid-path=/usr/local/nginx/nginx.pid \

--error-log-path=/usr/local/nginx/logs/error.log \

--with-pcre=/project/pcre-8.33 \

--with-zlib=/project/zlib-1.2.8 \

--with-http_dav_module \

--with-http_flv_module \

--with-http_stub_status_module \

--without-http_scgi_module \

--without-http_uwsgi_module \

--without-http_gzip_module \

--without-http_ssi_module \

--without-http_proxy_module \

--without-http_memcached_module \

--without-http_empty_gif_module \

--without-mail_pop3_module \

--without-mail_imap_module \

--without-mail_smtp_module \

--with-http_ssl_module \

--with-openssl=/project/openssl-1.0.1e \

--add-module=/project/nginx-rtmp-module-master

make && make install

修改nginx-rtmp-module-master/test/rtmp-publisher目录下player.html中rtmp推流接收地址和stream

增加nginx-rtmp-module-master/test/rtmp-publisher目录下播放器相关文件权限x

具体参考：http://www.iyunv.com/aHuner/p/3247068.html

2.rtmp实时推流

推流工具：Adobe Flash Media Live Encoder

必须同时推音频和视频，否则ffmpeg切片会报错，e2eSoft VCam做模拟视频输入，手机耳机插入PC麦克风插口做音频输入

3.安装x264

wget ftp://ftp.videolan.org/pub/x264/ ... 2245-stable.tar.bz2

tar jxvf x264-snapshot-20120718-2245-stable.tar.bz2

./configure --prefix=/usr/local/x264 --disable-asm --enable-shared

make && make install

vi /etc/ld.so.conf

加入：/usr/local/x264/lib

执行：ldconfig

4.安装aac

http://www.audiocoding.com/faac.html

./configure --prefix=/usr/local/faac--enable-shared

make&&make install

遇到错误：

mpeg4ip.h:126: error: new declaration ‘char* strcasestr(const char*, const char*)’

解决方法：

vi common/mp4v2/mpeg4ip.h

修改第123行：

#ifdef __cplusplus

extern "C++" {

#endif

const char *strcasestr(const char *haystack, const char *needle);

#ifdef __cplusplus

}

#endif

vi /etc/ld.so.conf

加入：/usr/local/faac/lib

执行：ldconfig

5.ffmpeg切片方案

./configure --disable-yasm --enable-libx264--enable-libfaac --enable-gpl --enable-shared --prefix=/usr/local/ffmpeg --extra-cflags=-I/usr/local/x264/include --extra-ldflags=-L/usr/local/x264/lib

make && make install

如果linux下出现 ffmpeg: error while loading shared libraries: libavdevice.so.55: cannot open shared object file: No such file or directory

vi /etc/ld.so.conf

加入：/usr/local/ffmpeg/lib

执行：ldconfig

切本地文件命令：ffmpeg -i test.ts -c copy -map 0 -f segment -segment_list playlist.m3u8 -segment_time 10 output%03d.ts

切网络地址命令：ffmpeg -i rtmp://192.168.42.128/myapp/test1 -c copy -map 0 -f segment -segment_list playlist.m3u8 -segment_time 10 output%03d.ts

设置视频编码库libx264和音频编码库libfaac：

./ffmpeg -y -i rtmp://192.168.42.128/myapp/test1 -pix_fmt yuv420p -vcodec libx264 -acodec libfaac -r 25 -profile:v baseline -b:v 150k -maxrate 200k -force_key_frames 50 -s 320x240 -map 0 -flags -global_header -f segment -segment_list playlist.m3u8 -segment_time 10 -segment_format mpeg_ts -segment_list_type m3u8 segment%05d.ts

6. nginx-rtmp-module切片

application hls {

live on;

hls on;

hls_path /project/nginx-rtmp-module-master/test/rtmp-publisher;

}

7.nginx实时rtmp播放地址

http://192.168.42.128/player.html

http://192.168.42.128/stat

8.HLS实时播放地址

http://192.168.42.128/playlist.m3u8
