Nginx RTMP 点播服务

在Centos6.5+Nginx+RTMP流媒体服务（直播、点播）一文中介绍了搭建点播服务的过程，按照conf中的配置，点播播放时可以支持两种协议，一种rtmp，另外一种是http，刚开始不知道这两种有什么区别，经过一番测试，有以下结果

rtmp vod（播放器不下载视频文件）
- rtmp://10.2.44.216/vod/mp4:large.mp4 可拖动
- rtmp://10.2.44.216/vod/flv:large.flv 不可拖动，需要使用其它工具插入关键帧，生成性的flv
http vod（播放器会下载视频文件）都可拖动
- http://10.2.44.216:8080/vod/large.flv 播放一开始，直接下载整个文件
- http://10.2.44.216:8080/vod/large.mp4 边播放边下载，貌似是播多少下载多少
