[Red5] simple red5 setup ?

Tue Nov 1 11:09:20 EST 2005

Hi Guys,
 Just a quick email.
 1. red5 isnt really ready for using yet, only fun and testing really at the
moment.
2. bandwidth check code looks interesting, i would think we would do it in
java though instead of js and have some method in the api which can be
called to run the check.
3. components, we will change the stream code once the refactoring code is
done so FLV: is an optional prefix. has anyone seen any other prefixes ?
