AMS, FMLE & pre encoded H.264 streams from IP cameras

Hello, I am looking to take pre encoded IP H.264 streams and re transmit via FMS as HLS packaged HTTP for apple products.

My question ... can FMLE allow me to pull in streams of h.264 rtmp or http source.

I do understand I need drivers, but, if I do have drivers, I just need FMLE targeting to FMS and HLS Live packager app. No need to decode and re encode source.

Part two ... How many independent streams can FMS(AMS) handle on the input side. I need AMS to act as a conventional broadcast video router. I need 3 in, and in IP stream logic, I would have infinite out?

Thanks

Ivan
