Probably common knowledge, but I was able to utilize the USB port on my LinkPi using one of these
https://www.amazon.com/dp/B0C2MDTY8P?ref=ppx_yo2ov_dt_b_fed_asin_title
This is the LinkPi
https://www.amazon.com/gp/product/B0CDPRZJWV/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
The USB input is just 'stream1' in the URL
http://xxx.xxx.xxx.xxx:8090/stream0
http://xxx.xxx.xxx.xxx:8090/stream1
Really affordable way to get 2 tuners.
Quick reminder. Amazon is having their second Prime day October 8/9th. During the last events, the LinkPi ENC1 V3 dropped to about $100. If you're in the market for one, those dates may have the same sale.
Just be aware that the ENC1 has an issue with black levels for some folks (including me). Different color spaces did not fix the problem although it did for some others.
Fortunately it's easy to return one to Amazon.
I am unable to enter into LinkPi GUI. i have the enc1-v3. I connected the LinkPi first to my netgear nighthawk but then even to my local network that my laptop is on.
I can ping it through cmd prompt and see that it's active but whenever i try to access the GUI interface, it says site failed to load. I even tried a hard reset on the LinkPi itself. Please helpš
Way back in the early days, much older linkpi firmware, I had to do hard reboots of BOTH the linkPi and my router. Soft reboots werenāt reliable at the time. Also, i had to change a the setting in the LinkPi to reserve a fixed IP address and use a static IP reservation in my router. That seemed to clear things up.
I also have a nighthawk router R7000
Just curious if you are having the same issue I am having when trying to play west coast channels. It pulls up the east coast feed. Did the link format change or is this some update now in the latest version of the NBC app that no longer allows you to play out of region channels?
Actually I quit using the NBC app as it was just too unreliable. I just watch those channels with YTTV now. They actually look better than the NBC app since YTTV has 1080p enhanced resolution (which basically means higher bitrate)
NBC app was completely unreliable during the Olympics, but since then it's been fine using the 9.9.1 version that doesn't have the dim screen issue at video start.
Has anybody messed around with the LinkPi Encoder API yet? I'm working on a script to auto-crop some of the Xfinity premium channels. I'm done with the part to identify the crop required to make those channels fullscreen width-wise, while still maintaining the broadcast aspect ratio.
Now I need to send the commands to the LinkPi to do the cropping on the fly, but I can't get logged in via the API. Pretty much nothing but "Authentication failed" responses.
API documentation is here:
I've tried Postman using the described procedure in the doc, plus a couple of curl commands -- which is what I actually want to use:
curl --digest -u "username:password" http://linkpi-encoder/link/system/get_sys_state
and
curl --digest http://linkpi-encoder/link/system/get_sys_state?username=admin%passwd=password
No joy. 
It all seems so obvious now, but it took a while to figure this out 
:
curl --digest -L -H 'User-Agent: Mozilla' -u "${LINKPI_USERNAME}:${LINKPI_PASSWORD}" -i "http://${LINKPI_IP}/link/user/lph_login?username=${LINKPI_USERNAME}&passwd=${LINKPI_MD5_PASSWORD}"
Your password needs to be md5 hashed for the URL, but that password needs to be used behind the -u without hashing.
The JSON response includes 3 hash values: L-HASH, P-HASH and H-HASH. Each of those needs to be included in subsequent curl commands, each behind its own -H. No other authentication is required in those subsequent commands -- until the auth expires and you need to login again.
Subsequent commands, once auth'd, would look like this:
curl -H "L-HASH: $L_HASH" -H "P-HASH: $P_HASH" -H "H-HASH: $H_HASH" "http://${LINKPI_IP}/link/some_api_endpoint"
What are the functional applications of API access of the linkpi?
For me, it's just as I stated above:
Hard as it is to believe, they have a half a dozen premium movie channels they broadcast with large black borders around all 4 sides. Channels doesn't have the ability to zoom, and doing it via the TV zoom is a hassle at best. So, that's my motivation.
The cool thing about the way I'm going to use it, is that the cropping can be done on the fly without having to restart anything. Plus using the encoder to do it, saves on the resources required to use ffmpeg for the task -- not to mention it's a relatively small addon to an existing encode.
What others might come up with, I don't know, but I thought I'd spare anyone the hassle of figuring out how to authenticate with the API. I may add an Action or two to OliveTin-for-Channels, now that I have this LinkPi API access -- and the Docker socket available.

On the live push page, the problem that after clicking the save button when pushing has been fixed, there is a probability that the push preview cannot be viewed.
h5 player page, added the function of creating full-screen playback shortcuts for specified channels
Optimize decoding network streams containing B frames
System underlying optimization
Updated to latest with no issues so far... BTW - the ENC5V2 is no longer available on Amazon, but I see that you can purchase it from Aliexpress or direct from the manufacturer.
Is anyone aware of a 4K60 capable HDMI encoder with multiple inputs that works with ADBTuner?
4K60 capture is going to be tough. It would require higher bandwidth than HDMi 1.4 and a work around for newer HDCP. Almost all these encoders work by āstepping aroundā older HDCP.
I don't even bother with 4K with this. I just use streamlinks to redirect me to the apps with the 4K feeds. There's only a finite amount of 4k channels much less 24/7 ones to be worth bothering anyways
A note - my LinkPi found an even newer 1031 firmware, with version 3.5.2, instead of 3.5.0

Updated my EncV2 and now itās memory usage is at 99% and get an error trying to load the video stream.
Anyone know of a fix for this?
I assume you mean the ENC5V2? What version firmware did you install?
You have probably already tried these but this is what I have done when I had issues in the past.
Start with a 5 minute HARD power unplugged/power off restart. I would also restart the router. Verify that it has not changed any of the settings internally on the linkpi
If that doesn't work I have also done some of the following at times for issues...
Reinstall older version of firmware...sometimes back a couple versions then reinstall new version if it is working again.
Hold the reset button for 30 seconds to reset everything and put information back in.
