The Wowza example RTMP players have a Flash player plugin that is named "on2video" in the FLA file. But I cannot figure out where this plugin comes from. I have a situation where the Wowza server is behind a firewall that is somehow preventing the JWPlayer plugin from working. I also tried the StrobeMedia Player plugin from OSMF and it didn't work. However the plugin that Wowza is using in it's examples works fine. Trouble is that I don't know it's origin or if there are any license issues. I have search the web and the Wowza site for any info on the On2 Video Player plugin for Flash and came up empty handed.
This issue could be fixed in the firewall but I have no control over that. Just putting that out so people don't recommend dealing with it at that level. Already working on that.
