I want to monitor my IP cam on my TV (both set to 1920 x 1080p). Since the IP cam uses ethernet and the TV has HDMI, I'm hoping my RPi2 will be a suitable interface. At this point, I'm unsure of my next step. How do I find the right software, or determine if this is even possible?
EDIT:
Now that I've become a bit more familiar with the Stack Exchange sites' format, etiquette, "best practices" etc., (Meta Stack Exchange was very helpful), I think I should elaborate on this question. I should have stated the constraints I was under, not in comments, but up here in the question (seems painfully obvious now):
The IP cam is currently connected to a security NVR. I've created some VLANS on a managed network switch, making one of the IP cams "shared" (ie it will be available to the the guest VLAN as well as the the security VLAN). This will allow me to send live video to an entrance way monitor (like in convenience stores). For this, I'm using an ordinary TV which has an HDMI input. I have no equipment available to work with, and my budget is low, so a PC with Windows isn't an option. That's why I'm trying to use the RPi2 as originally described in this question.
I've gotten good responses to this question, but wasn't able to make any of them work (there was always something I got stuck on). Pressure to complete my task made me improvise a solution; so I've decided to take the "answer your own question" route in order to update my situation and finalize this question. From my research, I'm inclined to believe I should use proper etiquette and wait before accepting my own answer. Since this post is over six months old, I'll wait at least a couple of weeks.
FINAL EDIT: It's almost three months since my last edit, so I figure it's time to put this post out of its misery. I was considering answering my own question, until I realized that my "Answer" wouldn't really answer my original question! So in order to be consistent with the SE format, I won't accept my own answer, or even post an answer at all because, well I don't have one. I would like, however, to wrap up this post since there has been at least SOME, interest in the question. Ummm, ahh, who am I trying to fool?! This post is the most auspicious thing I've done here at the SE sites! Anyway, just to tie up loose ends: how I finally completed my task (described above), ended up not even using a RPi. I found a 4-channel security NVR on eBay for US$ 28 and just use it as a converter box: it connects to the LAN network switch via its ethernet port, and sends out a video signal to a TV using its HDMI port. Just like I wanted to do in my "Question". Only thing is, it's not a RPi, and so I don't consider that to be an acceptable answer. I have, however made some progress learning to use my RPi. I never dreamed it would be so difficult for me when I started out eleven months ago. I had only ever used a WIN PC before, so I just took a little double click on your basic SETUP icon for granted. I HAD NOOOO IDEA!!!! Wow, what a shock it was to find out how involved loading up some software really is. And I still can't really handle it unless I can use a single APT-GET command and run it off my GUI desktop! But I did learn how to use it to control stuff over the WAN when I use my home PC to connect with a little SOCKET connection on my RPi I managed to string up, along with some bits of Python code I cobbled together. Nothing fancy by any means, BUT IT DOES GET THE JOB DONE! So I'll take any small victory I can get. Besides, now that the pressure is off, I actually find using my RPi... FUN!!!
PS I'm not really sure if it is considered good etiquette to accept an answer that I never even tried to implement but, OH well. If I come across information that says otherwise, I will change my acceptance at that point. The answer which I came the closest to actually succeeding at was the one given by Jon Clean that uses the NENPL solution using OMXPLAYER. The only thing that stopped me was finding out the URL of any one of my IP cams. I tried using Firefox's developer window to inspect pages of my cams, but just couldn't find the proper address. Ooooh so close! But since I'm accepting an answer I haven't accomplished, I have to give it to the motionEyeOS solution given by Andrei. The installation instructions were FAR less intimidating. I'd like to actually try them one of these days!
