[Red5] simple red5 setup ?

[Dominick Accattato]

Anyone trying to use the flash video components. There are issues with
interoperability at this time. I believe that I understand the reason why
there is a connection problem. some components send a prefix of flv: to the
server. We currently don't account for this, but we will look into getting
this working soon. Just a heads up. serve on!

example:
.\hosts\__default__\apps\oflaDemo\streams\flv:OFLA_PROMO (The system cannot
find the file specified)
  So, all we have to do is have a service that checks for the flv: prefix
and strip that. I'm sure the component makes other calls, but this is the
one that will return the streaming video.
