FluorineFx: Video Recording and playback (Flash/AS3 environment)

If you do not consider the security factor (anyone can connect FluorineFx for video recording without logon authentication), the server does not need to write a line of code, you only need to create a subdirectory under the apps directory as an application, and configure the rtmp Channel in the services-config.xml.

 

The following as3 code of the flash client is modified from the official Flash AS2 example of FluorineFx (of course, there are many optimizations in the details)
