一、方案選型

1. nginxGryphon
2. nginx-rtmp-module
3. ffmpeg
4. vlc播放器(android)

二、搭建流程

1. 下載nginxGryphon
   nginx 1.7.11.3 Gryphon.zip。

2. 下載nginx-rtmp-module并拷貝到nginx 1.7.11.3 Gryphon解壓所在的目錄。沒有怎么研究過該module，rtmp-module里面都是代碼，猜測重要的應該是stat.xsl這個文件。

3. 安裝ffmpeg工具

4. 在模擬器中下載vlc.apk 需要是x86版本的。

三、配置nginx

1. 增加rtmp節點

       rtmp {
           server {
               listen 1935;#監聽端口,若被占用,可以更改
               chunk_size 4000;#上傳flv文件塊兒的大小
               application live { #創建一個叫live的應用
                       live on;#開啟live的應用
                       allow publish 127.0.0.1;#
                       #allow play all;
               }
           }
       }
   

2. 在server節點中增加以下內容：

       location /stat {
           rtmp_stat all;
           rtmp_stat_stylesheet stat.xsl ;
       }
       location /stat.xsl {
           root ./nginx-rtmp-module/ ;
       }
   

通過配置完這個后，就可以在 "localhost/stat"，可以查看直播監控狀態了。
整體的配置文件如下(nginx-win-rtmp.conf)：

# user  nobody;
<p class="mume-header " id="user--nobody"></p>

#  multiple workers works !
<p class="mume-header " id="multiple-workers-works-"></p>

worker_processes  2;

# error_log  logs/error.log;
<p class="mume-header " id="error_log--logserrorlog"></p>

# error_log  logs/error.log  notice;
<p class="mume-header " id="error_log--logserrorlog--notice"></p>

# error_log  logs/error.log  info;
<p class="mume-header " id="error_log--logserrorlog--info"></p>


# pid        logs/nginx.pid;
<p class="mume-header " id="pid--------logsnginxpid"></p>



events {
   worker_connections  8192;
   # max value 32768, nginx recycling connections+registry optimization = 
   #   this.value * 20 = max concurrent connections currently tested with one worker
   #   C1000K should be possible depending there is enough ram/cpu power
   # multi_accept on;
}

rtmp {
   server {
       listen 1935;#監聽端口,若被占用,可以更改
       chunk_size 4000;#上傳flv文件塊兒的大小
       application live { #創建一個叫live的應用
            live on;#開啟live的應用
            allow publish 127.0.0.1;#
            #allow play all;
       }
   }

四、驗證

1. 啟動nginx服務
   命令行下進入到nginx.exe所在的目錄，并執行$ ./nginx.exe -c conf/nginx-win-rtmp.conf。
2. 啟動ffmpeg推流命令
   ffmpeg -re -stream_loop -1 -i ./rtmp_demo.mp4 -vcodec libx264 -acodec aac -f flv + "設置好的服務器地址"
   其中rtmp_demo是之前錄制好的一個mp4的視頻文件。
3. 由于模擬器中andorid的系統無法直接訪問windows的服務器地址，需要進行一次端口的轉發。
   adb reverse tcp:1935 tcp:1935
4. 在模擬器中打開之前安裝好的vlc播放器，并將播放地址設置成拉流的地址即可播放。
   adb shell input text "設置好的服務器地址"
