CarlFKhit tings with a hammer until lanchpad stops rejecting them00:11
CarlFKonce we figure out what we are using, I would _really_ like you to do them right00:11
CarlFKbut for now just trying to get micolous stuff up00:11
tumbleweedpragmatic :)00:12

xfxfmithro: LCA own 7 active HDMI > VGA converters.  i've just tested the output of HDMI2USB with one of them into a monitor with VGA and it appears to work02:37
xfxfmithro: i suspect will need VGA > HDMI for each room for the people who have VGA only.  any idea of converters/adapters to use which are HDMI2USB friendly outside of expensive scan converters?02:38
xfxfwell, sorry, i don't suspect, i've been asked to ensure we're covering for that02:38
CarlFKxfxf: 720p -> vga, right ?02:38
xfxfyes, 720p02:39
CarlFKI think mithro is planning on the vga daughter board being ready, so I would wait a bit on an answer before you buy anything02:39
xfxfokay, just again avoiding getting to the hackfest and pissing off LCA by having to emergency buy expensive things which are a fraction of the cost if bought in advance02:40
xfxfdefinitely want to lean towards perhaps purchasing a little too much over last minute panics :)02:41
CarlFKI remeber him saying he would cover the costs if he didn't deliver.  but I was only 1/2 paying attention to what it was he said he would deliver02:41
xfxf(AV gear from local retailers in AU is expensive++++++)02:41
xfxfi remember him saying that too, i don't think that's fair on him at all02:42
tumbleweedxfxf: I haven't yet found a VGA->HDMI convertor that offers a 720p mode02:46
CarlFKtumbleweed: you were looking for < $100 things right ?02:47
CarlFKI am sure I saw one for $35002:48
tumbleweedthere are presumably fancy ones that work02:48
CarlFKI took a 1/2 day fpga class and vga signal processing was a good bit of it.02:48
CarlFKseems it is pretty easy to word word word and great success.02:49
mithroxfxf: If you need to support VGA in, you'll need  VGA->HDMI adapters02:50
mithroThe HDMI->VGA side was the part which I'm confident about02:51
CarlFKoh oh ;)02:54
xfxfokay, i haven't a clue what's HDMI2USB compatible, any ideas?02:54
mithroNot really02:56
mithroxfxf: start with the cheapest thing you can find and work upwards?02:58
mithroxfxf: I have roughly 20 little USB screens here - are they useful for anything?02:59
xfxfi don't think i have time to do that anymore - we're 2 weeks out from the hackfest03:00
mithroxfxf: the cheapest ones are going to be easier to find right?03:02
xfxfcheapest in my eyes is buying something from overseas03:02
xfxfconverters aren't cheap locally03:03
xfxf2 weeks isn't sufficient to order something, then order something else03:03
CarlFKxfxf: how many do you need?  (5 rooms, right?)03:03
xfxf5 rooms yes03:03
mithroI meant locally03:03
xfxfand i don't have infinite funds to buy a bunch of random adapters03:03
mithroWhat does jaycar and DSE have available?03:04
mithroAnd how do they compare to your high end scalers03:04
mithroCan you when get your expensive scalers in time?03:06
xfxfjaycar/dse converters are terrible and overpriced, they're not remotely as close (none of them let you control input/output resolution - that said we don't need that), and perhaps03:19
xfxfi've got a few cheaper adapters here, i'll try to test them03:20
xfxfthe jaycar/dse stuff is all targeted towards consumers trying to hook things to their HDTV's, not quite what we're doing03:22
mithroYes, but are there many other options? If VGA scan converters are like $500 Aud03:22
mithroBeing targeted at TV's is good as they do 720p03:23
xfxfless so quality, more being dubious that they'll work at all03:23
xfxfi bought them for my blackmagic gear, didn't work03:24
xfxfbut will test03:24
CarlFKI bought a $45 one, wow was it crap03:24
xfxfthe 'expensive' scalers i like because you can lock down the input/output resolutions03:25
xfxfso they tend to work with everything03:25
mithroYes, but with the blackmagic gear we can't figure out why it's crap03:25
xfxfbut at this stage i'll take whatever works03:25
mithroWith the HDMI2USB we can see why03:25
xfxfsure, well, i'm confident i can buy 5x active VGA > HDMI adapters, but i've got zero way to know what they actually do03:26
xfxfif you think we can get most things working then i'm happy to do that03:26
tpbTitle: PCT-VHC11, VGA to HDMI Converter , with RCA cable, (at
xfxfi have one of these03:27
xfxfwill test it now03:27
mithroIf jaycar is $100 per room and good converters are $150 - then go with the good03:27
xfxfthe good are $400-$500 second hand03:27
xfxfand almost $1k new03:28
mithroIf jaycar are $50 and good are $500 - then we probably need to make do with jaycar03:28
mithroCan you hire them?03:29
mithroTime verse money trade off03:29
xfxfyeah but they'll be almost as much to rent for a week03:35
xfxfthis is why i bought mine03:35

tpbTitle: Extron RGB HDMI 300 A | eBay (at
mithroCarlFK: seems to cheap - but cheap enough that it might be worth the risk03:40
CarlFKits $350 new03:40
CarlFKExtron is the company that xfxf recomends for scalers03:41
CarlFKI kinda looked into this about 6 months ago03:41
CarlFKI should grab that for me...03:43
mithroCarlFK: probably03:43
xfxfthat's a model i'm not familiar with03:43
mithroExtron is a horrible company, and their gear is overpriced expensive crap03:43
mithrothat applies to pretty much everyone in the A/V space03:44
xfxfi assure you it's better than the shit AU retailers sell03:44
mithroand they are better then most in the space03:44
xfxfyeah, well, how long until hdmi2usb does scaling, huh? ;)03:44
mithroxfxf: actually - that is something I could get florent to work on during the hackfest :P03:44
xfxfalso, mithro, verifying something i spoke to you about a few weeks ago03:44
xfxfcosta hall, the keynote venue, will have two lecturns.  it's a VGA projector/system03:44
xfxfvenue is quoting a VGA switcher03:45
xfxfi think we should forgoe that, and put a HDMI2USB in w/ my expensive HDMI > VGA scaler03:45
xfxfand use that for capture + switching03:45
xfxfseems sane?03:45
xfxfonly fun thing there is the podiums may not be near each other03:46
xfxfand i know you wanted short lengths between laptop + hdmi2usb03:46
CarlFKxfxf: given the quantity of problems, I would not take on more03:46
xfxfCarlFK: it's not so much that, it's more having a VGA switcher in the mix complicates things for us03:46
mithroxfxf: Can you do a quick paper diagram (or Google Drawing) of what you are saying we should do?03:47
xfxfnot right now, i'm not meant to be working on any of this currently sorry03:47
xfxfi'm neglecting other responsibilities03:47
CarlFKxfxf: opsis board next to each podium, hdmi->vga -> whatever the venue does03:48
xfxfthe purpose of the opsis board also to do vision switching for what everybody sees on the main screen03:48
xfxfthis cannot be done with 2x opsis's currently03:48
CarlFKyou are adding reqirements03:49
CarlFKuse the opsis to record, let the venue do the switching.  hopefully they can handle that part ok.03:52
xfxfit means we can't use the hdmi2usb like in all other rooms03:54
xfxfwe have to place it after the vision switcher, which means converting the signal03:55
xfxfthat said i hear your point03:55
xfxflets not complicate this anymore03:55

xfxfmithro: i assume you're aware of pink/red text that goes through output0/output1 on the hdmi2usb looking really pixely?04:20
mithroxfxf: no04:20
xfxfmithro: i've been using my windows computer the last few days fed through a hdmi2usb to ensure it's stable04:20
mithroxfxf: example?04:20
xfxfhmm what irc client are you using?04:23
xfxfi can't find how to do ansi colors04:23
xfxfneed to something red04:24
mithroIs this on the capture or on the output?04:27
mithroxfxf: can you get a high quality photo that doesn't have the jpeg artifacts in it?04:29
xfxfthe jpeg artifacts you're seeing are what i am seeing on screen04:29
xfxfit's barely readable04:29
xfxfoh wait04:29
xfxfi see what you mean04:29
mithroxfxf: I need to be able to see the individual pixels around the text04:29
xfxfi'll upload the jpeg as off my phone04:29
tpbTitle: Meet Google Drive – One place for all your files (at
xfxfis that any better?04:42
CarlFKYou need permission04:43
xfxfi shared it with tim ;)04:44
xfxfbut i'll make it public04:44
xfxftry now04:44
xfxfalso default zoom looks compressed as hell04:44
xfxfif you zoom in to max it you can make out each pixel04:44
CarlFKxfxf: can you skip the hdmi2usb but also force the source to 720p ?04:47
xfxfthe source is 720p04:47
xfxfit's my computer04:47
xfxfand it looks perfectly at the same res hooked directly in04:47
xfxfalso the monitor i'm using has a nice 1:1 mode where it won't scale up the resolution04:47
xfxfthat photo is taken with 1:104:47
xfxfso it's absolutely representative of hdmi2usb output04:48
xfxfthe screen isn't altering it04:48
CarlFKcuz that looks like software04:48
mithroxfxf: can you take a photo of the same thing hooked up without the HDMI2USB04:48
CarlFKlike the video driver or something in that area scaling it04:48
xfxfit's not04:49
xfxfi'm looking at it right now plugged in04:49
xfxfi'll take a photo when my phone is above 5% battery04:49
CarlFKmithro: the encoder at quality 100 should show the same thing, right ?04:49
mithroCarlFK: the encoder isn't involved if you are doing HDMI in -> HDMI out04:50
xfxfmithro: i didn't think it was but to me, the screen looks 100% like it's being jpeg encoded04:50
xfxfi see jpeg like artifacts sometimes04:51
CarlFKmithro: I am thinking it might be interesting to see if the hdmi2usb is getting that same thing04:51
mithroxfxf: It is probably the YUV encoding - but I want to compare with and without pictures first04:51
xfxfah, colorspace would make sense04:53
xfxfi'll get you a picture as soon as my phone has charged enough to play ball04:53
xfxfi just checked the recorded video - it looks similar, but worse04:53
xfxfi'll see if i can save out a frame04:53
xfxfin positive news, voctomix has been recording perfectly at 30fps with hdmi2usb for 22 hours straight now04:53
xfxfvoctocore did something stupid last night though and i no longer can open the UI04:54
xfxfbut it's still recording perfectly, with av sync04:54
xfxfmithro: this is the output to the same screen direct from the pc, set at 720p, without the hdmi2usb in the chain:

xfxfmithro: I think there's a hdmi2usb issue with my laptops10:18
xfxfmithro: is it possible some usb chipsets are crappier?10:18
xfxfmithro: basically, on a desktop i5, i can capture from the hdmi2usb into voctomix no problems, no slowdowns.10:18
mithroxfxf: can you please explain what you think the problem is?10:19
xfxfif i do it on 2 different laptops, the hdmi2usb input eventually slows down to a really slow speed + i have to restart the hdmi2usb capture script10:19
mithroxfxf: yes, some USB chipsets are crappier then others - but that isn't that common10:19
xfxfi just split it up so the core/gui was running on the desktop, and the hdmi2usb input was on the problematic laptop10:19
xfxfand the problem came back10:19
xfxfwhich is 100% going to bite us in the butt at lca10:19

xfxfwould it be useful if i modified the gst-launch line we're using for voctomix and make it just save it out a local file10:21

seaLnei think so11:59
mithroI would guess you need to pull it in some direction?11:59
seaLnei was re-reading the data sheet11:59
mithroseaLne: it's an enable pin right?12:00
seaLneit has internal pullups12:00
mithroseaLne: since you have spare IO pins, why not connect them?12:01
seaLnewould we ever want to disable i2c?12:01
mithroseaLne: dunno, but better to have the feature and not use it :P12:06
mithroxfxf: any thoughts on what to put here ->
seaLnemithro: i'm not too sure what you were meaning me to do with the eeprom wp pullup?12:07
mithroxfxf / micolous: I've simplified the firmware situation on the website and the repositories12:07
xfxfdo you have / will you have a single page of easy to follow instructions to get somebody running with the hdmi2usb?12:07
xfxfbecause it's a bit of a wade through many pages and ask questions here thing at the moment12:07
xfxfi'm yet to try your prebuilt firmware that said, i'm still building it myself because i know that workflow12:08
mithroxfxf: well - the Opsis boards you just plug in and get a Webcam + Serail port without having to load anything12:08
xfxfwill I get the Opsis boards before everybody gets their crowdsourced one?12:08
mithroxfxf: maybe by a day or two12:08
xfxfbecause i'm happy to do a pretend i know nothing about the device and try setting it up from scratch following supplied instructions12:08
xfxfah, not much time12:09
mithroxfxf: you should get them this week sometime12:09
xfxfincluding customs?12:09
xfxfyou said GST was payable12:09
xfxfcustoms can hold shit for weeks...12:09
xfxfusually days, but can be weeks12:09
mithroxfxf: GST payment is normally like a 30 second thing - Fedex give you an invoice, you pay invoice - done12:10
xfxfah, not my experience, but hopefully that's the case12:10
mithroseaLne: the WP pin should have a resistor pulling to either VCC or GND. When the jumper is connected, you connect WP to the other value12:11
mithroSo when you connect the jumper, there will be current running through the pulling resister (as it is now connected between VCC and GND) but it should be a big enough value that it doesn't really matter12:26
mithro(the resistor that is12:26
seaLnemithro: ?12:27
tpbTitle: Imgur: The most awesome images on the Internet (at
mithroseaLne: assuming pulling up is putting it in "write protect" mode13:05
seaLnei've connected the level shifter EN now as well13:07
seaLnenow you can jumper the DIFF_CLK_X to LEDs instead13:08
seaLnemithro: should tofe 3v3 have a diode like the 12v?13:10
seaLneor would that cause to much of a drop13:10
mithroI think that would cause too much of a drop13:10
xfxfmithro: my VGA > HDMI converter i pasted earlier seems to work at 720p fine with the hdmi2usb13:11
xfxfthe video is slightly blurry, but it's VGA13:11
seaLnei saw these that might be usable
tpbTitle: PSG03649 - PRO SIGNAL - VGA And Audio to HDMI Converter With Scaler | CPC UK (at
seaLnemight find someone else selling them13:14
seaLneno idea if they are good though13:14
mithroFixed 1280 x 720p output resolution !?13:16
seaLnethere are others without the scaler but i thought for just now that would be useful?13:16
xfxfmithro: yep, 720p. i could set other resolutions, i got nothing through (assume it's ignoring the EDID data set by the hdmi2usb), but setting it manually worked13:17
xfxfit's not perfect but it's good enough13:17
xfxfVGA only should be a very small % of cases13:17
mithroseaLne: sadly it doesn't look like Farnell Australia stocks them13:18
seaLneyeah cpc is a different catalogue from "normal" farnell13:18
mithroseaLne: so, that schematic is looking pretty good13:52
mithroxfxf: you still up?13:55
mithroseaLne: I also notice we have that open pull request from you about the "make download prebuilt"14:07
seaLnemithro: i think that was superceded by some other thing?14:24
seaLneor rather that work flow was no longer through useful?14:24
mithroseaLne: maybe the mode-switch tool?14:24
seaLneas it still required a lot of the other tools it was only useful for lazy developers while i'd originally thought it might have been for users14:26
seaLneso i think it can probably be forgoten14:27
seaLnemithro: do you think there will be enough interest in tofe-vga to get it "manufactured" or do you think it will just be a low enough volume to place by hand? (this could effect size of passives)14:30
mithroseaLne: I'd go with passives which you can hand solder14:32
seaLneyeah, some will probably have to be a bit small to fit in some places. but it probably makes sense to make the rest larger14:33
seaLneand atleast the first batch would be by hand anyway14:34
mithrothe capacitors have to be reasonable large anyway I think?14:35

MaZderMindrestarting voctocore once a day avoids the buggest issues23:29
MaZderMindso it's a not-so-important thing currently23:29
xfxfonce a day is fine - the GUI slowing down every few hours will confuse volunteers (it's not us operating the equipment, it's a team of ~12 others - we're core team) but we have a workaround that's acceptable23:32
xfxfyou mentioned you were using nagios or something to monitor things - are the configs for that online anywhere?23:33
