I have a test page set up here: http://www.scdot.org/inside/commission_video2.aspx . It works internally on our network, but appears to fail outside our network, although it does occasionally work.
When the player fails, Firefox reports Jwplayer is undefined. The stream is there, I can view it via the jwplayer web site. The address for the stream is: http://220.127.116.11:1935/live/commissionExternal/playlist.m3u8
Can you take a look and make suggestions?
