RTMP save and watch with 1h delay (no replies)

HI,

Nginx receive rtmp unsecure link from admin
-> restream the same rtmp to users just using secure link & record to any format
-> if user want, he can watch transmision choosing 1, 2 or 3h delay. Delay is static and cant be change during watching.

Is such scenario possible in nginx-rtmp? Can you give me tips to configure it?
