Hi
1- If your upload your files locally on your SNS , SNS will be the origin server and will be responsible for "RTMP and HTTP". For External hosting files which is highly recommended by Cisco , you have to use external streaming server and Wowza server or Adobe flash server and this will allow all videos .flv , MP4 , WMV,,etc displayed and without streamin server the videos won't be displayed. I hope to take a look for the below :-
