How to stream from flash NetStream to ffmpeg?

Question

RTMP

Greetings!
For several days I have been trying to figure out the problem: I need to redirect a video stream from 1 rtmp source to another.
It turned out to receive a stream via flash (the connection is made using a token), but it is not possible to implement a method for redirecting this stream to the desired address. There is an option with redirection through ffmpeg, but it is not clear how you can take a stream from NetStream and send it to ffmpeg.
An option is also suitable, in which it will be possible to at least dump the video from the stream through the same ffmpeg (there is a server address, a token and a stream name).
Please tell me the implementation options or alternatives, if there are any.
Thank you for your attention!

Do you work with Flash plugin or AdobeAIR? If option is 1, then no options :(
