    Livestreaming via PS4 to a local RTMP server

Live stream from your PS4 to a local computer running an RTMP server by intercepting the twitch.tv stream.
Requirements

DD-WRT enabled Router (or router with iptables compatibility)
nix Envirment
nginx with the nginx-rtmp-module

IPTables

To capture the outgoing RTMP stream, I'm using NAT redirection on the Twitch.tv IP range for port 1935.  This will cause normal twitch streaming to break.
iptables -t nat -A PREROUTING -d 199.9.0.0/16 -p tcp --dport 1935 -j DNAT --to-destination <local_ip>:1935
iptables -t nat -A POSTROUTING -j MASQUERADE
You can ssh into your DD-WRT enabled router and add these rules, any future requests will be redirected.
nginx-rtmp-module

Here is the config for the rtmp module and the bash script I use to convert from FLV to MP4.
rtmp {
	server {
		listen 1935;
		application app {
			live on;
			recorder storage {
				record all;
				record_path /home/user/gameplay;
				record_unique on;
				exec_record_done /home/user/gameplay/.encode.sh $path $basename;
			}
		}
	}
}
