http: First download FLV to the local cache via IIS, and then play the FLV via the Netconnection local connection, which is to play the local video, not the video of the playback server. So this flv can be found in the local cache. The advantage is that the server downloaded this flv, the server is not consumed, save the server consumption. The disadvantage is that FLV is cached on the client side, and the privacy of the FLV is bad.

rtmp mode: Connect to the FMS/RED5 server via Netconnection, and play the server's FLV file in real-time, this way can choose the video play point (SEEK ()), The advantage is that the FLV file cannot be found in the local cache, as it is not necessary to cache a full FLV file locally to select the playback point. Its advantage is that FLV will not be cached on the client, the privacy of FLV good, its disadvantage is to consume server resources, the connection is always real-time.

In a word, the HTTP mode is local playback, rtmp mode is the server real-time playback, depending on the need.
