I have this configuration:

rtmp {
server {
listen 1935;
chunk_size 4096;

application Live{
live on;
record off;
hls on;
hls_path tmp/hls;
hls_fragment 5s;
}
}
}

What i need to do to add FLV support to reproduce live streaming in a local SWF with flvplayback in Flash CS6?

And how can i create specific keys to stream, just to prevent anybody can't rtmp in my server? i want to create some restrictions
