用nginx搭建http/rtmp/hls协议的MP4/FLV流媒体服务器

前前后后搭建了两三个星期，终于可以告一段落，nginx实在是有点强大。写一篇笔记来记录一下这个过程中的思路和解决方案。

    #user  nobody;
    worker_processes  1;

    error_log  logs/error.log;
    #error_log  logs/error.log  notice;
    #error_log  logs/error.log  info;

    pid        logs/nginx.pid;

    events {
        use epoll;
        worker_connections  1024;
    }

    rtmp {
        server {
            listen 1935;
            chunk_size 4000;

            # video on demand
            application vod {
                play /usr/local/nginx/html/flv_file;
            }

            # HLS
            # HLS requires libavformat & should be configured as a separate
            # NGINX module in addition to nginx-rtmp-module:
            # ./configure … –add-module=/path/to/nginx-rtmp-module/hls …
            # For HLS to work please create a directory in tmpfs (/tmp/app here)
            # for the fragments. The directory contents is served via HTTP (see
            # http{} section in config)
            #
            # Incoming stream must be in H264/AAC/MP3. For iPhones use baseline #H264
            # profile (see ffmpeg example).
            # This example creates RTMP stream from movie ready for HLS:
            #
            # ffmpeg -loglevel verbose -re -i movie.avi  -vcodec libx264
            #    -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1
            #    -f flv rtmp://localhost:1935/hls/movie
            #
            # If you need to transcode live stream use ‘exec’ feature.
            #
            application hls {
                hls on;
                hls_path /usr/local/nginx/html/flv_file;
                hls_fragment 10s;
            }
        }
    }

    http {

        include mime.types;
        default_type application/octet-stream;
        sendfile on;
        keepalive_timeout 65;
        gzip on;
