    I'm really coming up short trying to figure out how to turn on debugging in the hyperiond process...


    I saw a couple posts citing 'hyperiond hyperion.config.json --debug' as the command to do it, but this certainly does not work - throws a 'bad parameter --debug' error.


    Can someone please help me out? I can't figure out why hyperion wont respond to protobuf messages and not being able to enable debugging certainly doesn't help.


    Thanks!

    I picked a few of these up, they definitely clean up the wiring cabinet a bit as I no longer need to convert HDMI to CBVS back to USB. I can report the same 'power feedback' and heat issues present on my sticks, however, I am (read: taking a risk) taking advantage of the feedback and powering my Pi Zero W over it. I understand that I am forgoing the 'fused' circuit by backpowering through the OTG port to VBUS, but im okay with the risk of a $5 pi. my understanding is that there is 50mv on a +5v line on hdmi, and while that's not enough to ever power a Zero, I am assuming the power from my cheapo HDMI 1x2 splitter is carrying over, as when I unplug power to the splitter, the LEDs stay dimly lit on the splitter, but the Pi does not stay powered. I did not change any software settings for this, purely swapped out my HDMI to CBVS -> Fuchai USBTV Grabber circuit for a HDMI to USB USBtv007 chip. I have not noticed any issues running in this fashion for the past week, outside of an extremely warm HDMI to USB adapter. I will say the screenshots look noticeably clearer, and less distortion is present in the grabber image. the LEDs seem to be responding faster, but that may be purely a placebo on account that im staring at the lights now looking for issues.


    That is exactly where my mind went with this too... Would we be able to run a pi zero off the HDMI power... Well thanks for putting your hardware on the line! Please let us know if you run into any trouble!

    Okay so I'm back to report my progress so far.


    Here is the current setup:
    Splitter: https://www.ebay.com/itm/Exper…D-4K-2K-60Hz/142379360229
    Scaler: https://www.hdtvsupply.com/18gbps-repeater-4k-scaler.html
    Convertor: https://www.amazon.com/gp/product/B06XHKF945
    Capture: https://www.amazon.com/gp/product/B0126O0RDC


    Right now, I'm thinking the convertor is messing with the configuration. As part of its standard it outlines support for 2160p, but only at 30hz. The scalar is supposed to scale from 4k@60 -> 1080p@60, but I have a feeling the convertor that it is plugged into supporting 4k@30 is causing some problems as the scalar never actually shows a 1080p output from the 4k signal (it has an indicator that show what the input and output signal are). I could probably test this theory by hooking up a TV that only supports 1080p maximum, but I don't have access to one at the immediate moment. I'll update this if I'm able to test with one.


    In the meantime, I ordered this convertor that does only support 1080p max: https://www.amazon.com/gp/product/B06W9LQDBB. I sure am hoping that helps.


    If not there is only one other splitter I could try that another user did report success with here (the only reason I didn't initially is because I wasn't sure if it supports CEC - the seller said it didn't, but that user confirmed it working for them at least).


    So the quest continues! :facepalm:


    Gotcha, thanks for the quick response!


    I just grabbed this one: https://www.amazon.com/gp/product/B06W9LQDBB which seems to be the same product just rebranded.. Will update this when I get that in a couple days.


    This project is exhausting me lol

    Hey diddy, did you have any trouble with the scalar turning on and off? My initial tests are not going very well unfortunately - the scalar lights up the '4k' in both the input and output and then turns itself on and off (at least what it seems like), causing the TV to go dark while it is cycling. I'm yet to see it actually scale a 4k signal to 1080p...


    I assume you are using an HDMI -> RCA adapter, mind linking to the one you are using?


    The one I have outlines support for 2160p, but it only supports it at 30hz... So maybe I need to grab one that only supports 1080p to make the scalar work as expected?


    If not then I'm thinking I might need to try yet another splitter. ugh.

    I got a little time last night to fiddle with screenrecord over adb, and I'm pretty impressed by how responsive it was! When I was experimenting with that a couple weeks ago using my phone, there was a bit of latency that made it seem like it wouldn't work well. But on the shield it is a bit snappier!


    I am trying to get STF working on raspbian, but it is a bit of an uphill battle for me. I have an armv7 docker image of STF and a working copy of ADB installed on raspbian, but I'm not very familiar with docker so I am having some trouble getting all the pieces to work together. The end goal of that would be to use minicap to grab the screen as it is supposed to be relatively lag-free.


    I can confirm that things like netflix only output black though, so that would probably demand root access and possibly xposed to get around.


    Any idea on how to most effectively port the video stream to hyperion - preferably without just playing it and using the internal frame grabber?

    Very cool OLAS, I'll have to mess around with this!


    In my limited trials with screenrecord there was usually about a second or so delay between the screen and the and the resulting video feed - have you been able to reduce that latency?

    Thanks for the response.


    Understood, I'm thinking (read as: praying to all the gods) I might be able to make it work with my configuration. ARC Isn't a concern for me since my shieldtv provides all the functionality from the TV I would need ARC for. I did pick up this thing (https://www.hdtvsupply.com/18gbps-repeater-4k-scaler.html) which I am hoping will solve any issues with the signal before it hits the convertor.. So hopefully all the pieces will fall into place for me!


    Great work with the windows screen grabber also! I would love to figure out something for android but it presents a lot of problems.

    Hey thanks for the reply!


    Wow I gotta say, that isn't a problem I would have anticipated it having! What resolution were you running that one at?


    I decided to grab one since they are so cheap (the least I can do to give back to this community is document my folly so someone else can learn from it), maybe heat problems are why most of the devices are in metal housings. Are those heat sinks anything specific you picked up, or did you just cut some down to size?

    Sabaat - am I understanding correctly that you where going directly from the splitter to the RCA adapter? Is that a sustainable setup (assuming you have it working now)?


    I kind of have the feeling that your converter may have burned out because it was being forced to run 4k@60 - I have that same one and I believe it only supports the HDCP1x standard where 4k@60 requires the HDCP2x standard. Purely speculation.


    I'm trying to make this work with my setup, but the splitter I tried thus far has no edid management and forced my resolution (I'm using a shield TV) to 1080p.


    I did however grab a little gizmo that is supposed to downscale a 4k@60 signal to 1080p@60 (which is compliant with HDCP1x), but dumb me didn't realize I need a splitter with edid management to actually use the feature the way I intend. The only problem is the splitter advertised to work with it does not advertise as supporting CEC, so I am a bit hesitant to grab it right now.

    Hey, wanted to let you know I did find splitter that does 4K@60 and supports CEC!


    https://www.rocketfishproducts.com/pdp/RF-G1603/5986903
    per the manual:
    https://files.bbystatic.com/lE…90_QSG_V1_EN_Final_lr.pdf


    This device passes CEC* commands sent by your components. If you don’t want it to do this, it can be disabled in the device’s menu. See the user guide or contact the manufacturer for more information.

    There may be hope! I am probably going to scoop one - if I do I'll report back here

    Okay I got a response from HDfury:


    We have no device that can convert 4k@60hz to 4k@30hz. All our devices work by scaling 4k@60hz to 1080p@60hz.
    The only devices that work for new hdcp 2.x devices 4k@60hz for scaling 4k@60hz to 1080p@60hz is the vertex and linker.


    The uhd splitter and splitter 4k pro only work with old hdcp 1.4 x devices for scaling to and from 4k to 1080p and 1080p to 4k. So it will not work with hdcp 2.x devices such as the xbox one and ps4 and uhd bluray players.


    Hope this explains it better.


    So it seems the cheapest device HDfury has to do this would be the 4k->1080p scaler. Would probably solve the problem but that is a pretty steep price ($180 as of typing this).


    The product you linked to earlier is starting to look pretty appealing.


    EDIT: Decided to pull the trigger on that scaler from hdtv supply - hopefully that will get me to where I need to be!

    Well I think I did source that product you linked to to an american retailer:
    https://www.hdtvsupply.com/18gbps-repeater-4k-scaler.html - $85 as of typing this which isn't too bad.


    Here is another device that is slightly more that seems to do the same thing, although I'm not sure if you would need to use their splitter to make it work:
    https://www.hdtvsupply.com/4k-down-converter.html


    I did also email HDfury for clarification on their gizmo, as the description does say "Up to 4K30 4:4:4 or 4K60 4:2:0" despite being HDMI rev1.4 - so let's see what they say


    EDIT:
    Actually, if the device I linked to here and the one you linked to are in fact the same, the description on the one I linked to says "Supports scaling up/down between 4K and 1080p (no frame rate conversion)"... So that may not even help then?


    EDIT2:
    Well damn, even the mythical 4K link by HDfury is incapable of converting the framerate (see the bottom of https://www.hdfury.com/4k-link…caling-modes-in-progress/). This is looking much more difficult than I anticipated.


    EDIT3: last one I swear!
    Actually frame rate conversion may not be a problem if downsampling to 1080p since 1080@60hz should still be compatible. I think I'm starting to overthink some of this!
