nginx-rtmp 流媒体服务器的搭建(采集桌面,手机直播)
在线Demo,直播自己的pc机桌面音视频(现在就一单线路,1M带宽,2个人向同一个目录下推送m3u8、ts文件肯定不行,之后再改,资源有限)
1、下载ffmpeg及脚本
http://download.csdn.net/detail/pqy15005917185/8160799
2、安装screen-capture-recorder(采集windows桌面、摄像头)
下载地址：
http://download.csdn.net/detail/pqy15005917185/8160801
直接安装就ok了，安装之后才可以使用bat脚本的
“-f dshow -i video=screen-capture-recorder -f dshow -i audio=virtual-audio-capturer”
3、解压,点击"流服务器直播.bat",运行如下图
4、vlc访问地址“rtmp://182.92.69.21/hls/test” 或者直接用iphone来访问“http://182.92.69.21/hls/test.m3u8”
使用环境:
https://github.com/arut/nginx-rtmp-module nginx-rtmp流媒体模块
https://github.com/rdp/screen-capture-recorder-to-video-windows-free 采集桌面、摄像头
nginx-rtmp的下载,直接下源码解压就ok了,我放在这里/home/dev/pengqiuyuan/nginx-rtmp-module-master
https://github.com/arut/nginx-rtmp-module
在编译nginx的时候添加nginx-rtmp模块的路径
./configure --add-module=/home/dev/pengqiuyuan/nginx-rtmp-module-master --with-http_ssl_module
make
make install
(1).chunk_size:流整合的最大的块大小。默认值为 4096。这个值设置的越大 CPU 负载就越小。这个值不能低于 128。
(2).listen 1935:给NGINX添加一个监听端口以接收RTMP连接,iptables不需要开放1935端口。
(3).application hls:HLS协议支持。hls_path(m3u8文件生产路径)、hls_fragment、hls_playlist_length(5个分片,每片11s .注:这样设置实时直播延时在1分钟左右)
(4).http请求地址(http://182.92.69.21/hls/test.m3u8)
(5).vlc播放rtmp流(rtmp://182.92.69.21/hls/test)
(6).hls_path和location /hls{alias}的路径保持一样如:/home/dev/pengqiuyuan/streaming ,目录下面保存的是客户端推送到流服务器的m3u8、ts文件

之前遇到丢帧的问题,real-time buffer 276% full! frame dropped!

桌面音视频采集成功的例子:
ffmpeg -f dshow -i video=screen-capture-recorder -f dshow -i audio=virtual-audio-capturer -vf scale=1280:720 -vcodec libx264 -r 60.97 -acodec libvo_aacenc -ac 2 -ar 44100 -ab 128 -pix_fmt yuv420p -tune zerolatency -preset ultrafast -f flv "rtmp://192.168.1.50/hls/test"
ffmpeg(带脚本)下载地址,流媒体服务器搭建好之后,修改bat脚本里的推送地址“rtmp://192.168.1.50/hls/test”,直接点击运行就可以向服务器推送了,之后“/home/dev/pengqiuyuan/streaming”目录下面会生产m3u8、ts文件就成功了 下载地址：http://download.csdn.net/detail/pqy15005917185/8160799
阿里云就1M的带宽,被占的满满的,下载地址换到csdn上面好了
整体思路是 nginx-rtmp(流媒体服务) + nodejs(即时聊天)
