Thank you all for your replies to my post. I really appreciate them. I am still deciding if this is the path I want to take. I have been reading post in this forum and my head is spinning. I may have misunderstood about what this setup will provide. So this only works on TVE channels or all channels? Does it support Sling TV channels?
Thank you
It works on all channels. Don’t know about Sling TV. I use it with Directv Stream and it allows me to tune to any channel in my package.
Found this on a Sling TV search in Playground:
Unfortunately, it looks like a no-go on Sling for now.
It works well from the standpoint of opening the app and launching content, but it appears that there aren't any direct links to "channels" in Sling TV. All of the links in the guide are for specific programs in the schedule and when that program is over the link no longer works.
Yes. Both ah4c and ADBTuner work with Sling deeplinks.
Yeah i setup a test late last night using ADBTuner and a Shield tv box as the feed for SlingTV. This explains why it didn't work correctly.
The package names threw me as i didn't know what hey where or where to get them. I wanted to attempt to test this before ordering the HDMI encoder box.
Deep Links? Where do you get those from?
There's really nothing to test until you have the hardware. Deeplinks, which are not always easy to uncover, are what allow virtual tuning without needing to emulate a remote control. They typically result in faster, more accurate virtual tuning.
Here's my post from back-in-the-day, when I figured out how Sling deeplinks work. Others have made similar discoveries for other streaming apps:
The most common mistake people make with Sling, is they grab the asset ID rather than the channel ID, which is what @jagrim was referencing.
I think I am going to buy the single port version for now. I currently have a 2nd gen ONN Android tv box that is wifi only. I would like to do away with having to power it and the WayPonDEV Link Pi ENC1-V3 4K NDI HDMI Encoder box and use POE since I have a POE switch. What adapters/cables do you recommend?
Thank you
Edit: I found these after reading thru this thread.
Not sure if this is the correct topic in the forum, but since I'm moving my Link Pi Enc5-V2 encoder to POE, the below items allowed me to put add all (3) of my ATT Osprey devices to POE. I can confirm that these work!
@spammedeeper
The adapter plug was the hardest thing to source.
Thanks, those buggers are hard to shop for. I had resigned myself to sacrificing the factory power supplies and soldering wire.
I'm working on setting up ch4c with a MeLE Quieter 4C running Windows 11 Pro, and a LinkPi ENC1-V3. I'm using a USB to HDMI capture card to give me a second input.
When looking at the Windows system, using Chrome Remote Desktop, things are looking as expected, with both desktops visible:
Also when connecting to the second stream using VLC, I'm also seeing what I expect:
But when looking at the LinkPi WebUI, I'm not seeing what I expect for previews. The HDMI input looks good, and the Mix looks good -- but I have no Preview for the USB Capture Card. Has anyone else seen this behavior? I'm running version 4.3.2 of the LinkPi firmware, which is the latest as of this writing:
That tends to happen at times for some reason. Try replugging it. Either that or do a factory reset
Factory reset was the answer -- thanks!
I bought the adapter listed below to power my single port Link PI and i would like to buy another one to power my ONN 4K Pro box as well. I just wanted to be sure its the right one to get?
Anyone have an idea which POE Ethernet Adapter i need to purchase to use with my ONN 4K Pro box? I appreciate any help i get on this.
Thank you.
I read over the ADBTuner forum post and missed that somehow. I need to slow down and do better researching.
Thank you so much I really appreciate it.
I bought myself a LinkPi Enc1-v3P model and trying to check its capabilities. I hooked up a FireTV stick 4K to its hdmi input and played a 4K plex stream. The interface on the dashboard shows '1080P60', while i was expecting it to show 4K.
Can LinkPi take in a 4K input?
It can if you set it up that way in the video settings for the Linkpi. Its only 4k30fps however.... my advice, forget about 4k and run it at 1080p 60fps. I have the 5 port and if i set more than a couple to 4k the cpu starts choking... not really relevant for you since you have the single port but i would rather have 60fps than 30. FWIW
100% everything @slampman said... 
if this is the one you have... LinkPi Enc1-v3P
All the LinkPis max out at 4K30 (if they are the ones that support 4K) so make sure you are setting your output from the firetv to that. If I tried to set it to something higher my Apple TV would change the output BACK to the 1080 setting since 4K60 is not supported.
I am running the 5 port version. I don't have the Internet speed to really test it...I drop frames even at 1 input set to 4k youtube stream... AND the encoder specs says max 3 - 4K30 encodes... I am not surprised if it bogs down at 2 though as @slampman says.
Here is a pic showing the HDMI-3 on mine set to 4k30 but I never run more than 1080-60 normally. Just as a side note don't forget these only encode output to stereo also.
Late Edit...
AS I look at the Note on the Amazon listing in this pic...
I see that they say your unit supports 1080P30x4 encoding/decoding..which they say is a reference for what can be encoded/decoded at once.
Which means your unit should support up to 2 - 1080P60 streams (1080P30x2 for each one) OR 1 - 4KP30 stream.
This would also make sense what @slampman said about our units struggling with more than 2 4K30 streams since our spec says 1080P30x8 EVEN THOUGH it also says it can encode 4KP30x3 right above/next to that on their website. 
I am looking to do a 2 tuner ADBTuner setup. Will connect 2 onn 4Kpro to appropriate LinkPi encoders. My question is am I better off with 2 LinkPi Minis or an ENC1-V3 with a USB 2.0 Capture card as mentioned elsewhere? Will the USB solution have lower quality on that port? (it is a bit lower cost than the Dual Mini approach) TIA for any insight.
