[rtmpdump] rtmpsrv with ffmpeg

[Chardazle]

When trying to use librtmp as a server I am having trouble getting the 
initial handshake to succeed.

The problem can be seen with the rtmpsrv sample.

For example, using ffmpeg as the client with something such as:

   ffmpeg  -f lavfi -i testsrc  -f flv rtmp://127.0.0.1/live/instance

fails to connect.

The rtmpsrv fails with:

   $ rtmpsrv
   RTMP Server v2.4
   (c) 2010 Andrej Stepanchuk, Howard Chu; license: GPL

   Streaming on rtmp://0.0.0.0:1935
   WARNING: SHandShake: Client not genuine Adobe!
   ERROR: Handshake failed
   Closing connection... done!

Is there something else that is required to satisfy that "genuine Adobe"?
