DeliveryHDS

HDS指Adobe的Http Dynamic Stream，和Apple的HLS类似。

HDS规范参考：http://www.adobe.com/devnet/hds.html

Build

编译SRS时可以打开或者关闭HDS，详细参考：Build

./configure --with-hds

Player

Adobe的HDS可以在Flash播放器中，使用OSMF播放器打开。

HDS Config

conf/full.conf中hds.srs.com是HDS的配置实例：

vhost __defaultVhost__ {
    hds {
        # whether hds enabled
        # default: off
        enabled         on;
        # the hds fragment in seconds.
        # default: 10
        hds_fragment    10;
        # the hds window in seconds, erase the segment when exceed the window.
        # default: 60
        hds_window      60;
        # the path to store the hds files.
        # default: ./objs/nginx/html
        hds_path        ./objs/nginx/html;
    }
}

配置项的意义和HLS类似，参考HLS config

Why HDS

为何SRS要在SRS2引入HDS？主要是SRS的HTTP服务器重写，以及文杰哥对于HDS很熟悉。另外，加入HDS不会对SRS现有结构有影响。
