LinkPi encoder family

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?

This was suggested by @Rockies in the ADBTuner discussion:

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?

#288

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

@trumee

100% everything @slampman said... :+1:

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. :man_shrugging:

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.

#291

I did the enc1 and usb. the only shows i'm using ah4c for are cartoons and news, so I only encode to 720p and can't speak to 1080p although I think others report it works just as well

#293

Buying two of either device will give you nice 1080P input. Traditionally, the USB 2.0 on the ENC1v3 has limited video capture to 720P. However, user over in the ADBTuner thread, @mackid1993 said he is getting good results with a ENC1v3 and a nicer USB to HDMI capture device.

I'm a little leery about using the USB 2.0 port even with that report . The Elgato described says it needs a USB 3.0 port. Regardless, 2 LinkPi minis were cheaper than the ENC1v3 and the Elgato Capture card so I went with that.

I can confirm I'm getting 1080p60 out of it. Those Elgato capture cards can go up to 4K30.

#296

I have to say, I'm still perplexed by this. It's a happy development as I was stuck at a max 1080p50 before. Granted I was not using the Elgato. I'm wondering if the newer ENC1v3 have USB 3.0 now.

EDIT: I guess the only way to know for sure is to order an Elgato and a new LinkPi, test with my existing gear. I will report back.

#297

Yup! It looks like it does!

Very interesting. My original release ENC1v3 has always shown hardware supports Super Speed (3.0), but I could never get USB3 devices to enumerate at 5000. Even in your picture, it looks like the Cam Link is connecting at High Speed, so I assume still USB2. That Elgato must be doing some sort of magic. Impressive.

#299

Maybe try picking up an Elgato Cam Link before picking up a new LinkPi? I believe they're on sale right now. Best Buy even has them for same day pickup.

My thoughts exactly! Thanks for contributing to the community.
