cr1901_modernmithro: You need me to create a freq counter, but the minispartan6 currently does not use the HDMI2USB core. Should I wait for shenki, or just try to brute-force support for now?00:04
cr1901_modernwait for shenki* to finish the port00:04
mithrocr1901_modern: You should be able to do everything independently00:05
mithroIn terms of urgency, I need that frequency counter stuff yesterday too...00:06
cr1901_modernSo did you implement it yourself? Or do you not need it anymore?00:06
mithrocr1901_modern: No, I haven't had the time yet00:06
cr1901_modernAlright, let's see what I can do.00:07
cr1901_modernIt can't be THAT tough to add a freq counter. You just need me to add two CSR registers and some defines for it, right?00:08
mithrocr1901_modern: well, I think we want a little more then that - but probably a good start00:08
cr1901_modernmithro: Why do you think that I can do everything independently? The BaseSoC doesn't have HDMI support? I mean, sure I guess I could write something that sniffs the traffic, but I assumed that you already had gateware that handled being able to extract data from HDMI streams (or at least split it).00:12
cr1901_modernDoesn't matter I guess; I mean, I have the warmcat article open00:12
mithrocr1901_modern: yeah - you only care about the two vsync/hsync pins00:12
cr1901_modernI hope my computer isn't "too smart" and doesn't try to stop sending data when it doesn't actually detect a valid monitor lol00:13
mithroI think we can start with number of cycles the pin is high and number of cycles the pin is low?00:16
cr1901_modernSure, that's cool00:19
cr1901_modernMay I take a bit of time to ask about project layout?00:19
cr1901_modernmithro: ^^00:19
mithrocr1901_modern: see the existing repo00:33

xfxfmithro: you around?08:54
mithroxfxf: kinda08:55
xfxfmithro: i notice the boards have headers for LED's and reset, should i hook any of the case things to it?08:55
xfxflike, is there a power button / LED?08:55
mithroxfxf: yes - but the firmware doesn't support them yet :P08:55
xfxfah, np08:55
xfxfcases arrived today08:55
xfxfi'm assembling two for testing and will leave the rest for the hackfest08:55
xfxfyuou're right, those cases i bought are horrible08:55
xfxfcan i recommend we put these new cases up on the hdmi2usb site somewhere as recommended?08:56
mithroyou mean like https://opsis.hdmi2usb.tv/getting-started/case.html ?08:56
mithroxfxf: Also signed up for Amazon referral program, so we get money if people buy through that link08:57
xfxfah neat, didn't see that08:57
mithroxfxf: It's about 7 days old I think :)09:00
xfxfthe power is a bit annoying09:03
xfxfi saw a bunch of very short barrel extension cables, getting a few of those might be nice09:04
mithroxfxf: How big are your power bricks?09:20
xfxfi have a mix of power bricks and wall warts09:20
xfxfpower bricks are 3A09:20
xfxfi've plugged ine of the power bricks09:20
xfxfi don't like how the cable now hangs out of the case with the brick on it09:20
xfxfi can see the connector on the board getting damaged09:21
xfxfCarlFK: when do you leave the US?09:21
xfxfmithro: thinking about getting 10x of those09:23
mithroxfxf: I had a plan of mounting the brick inside the case where the fan is09:23
mithroxfxf: but I'm guessing your bricks are too big?09:23
xfxfthey are yes09:24
xfxfi don't think you'd get a brick that would fit, it's a fairly small area09:24
mithroxfxf: we have ones at work that do09:24
xfxfok, i'd need models, because i had very little to go by when ordering09:24
xfxfyou literally said >1a 12v :P09:24
mithroxfxf: they aren't the right voltage09:25
xfxfah, right09:25
xfxfthoughts on ordering those extension cables?09:25
mithroxfxf: It would be good if we could get some "plugs" which fit in the holes somehow with them09:26
xfxfi'm not sure we've got the time to be too picky now09:26
xfxfgiven we need these in a week09:26
mithroxfxf: are they long enough?09:26
xfxfwell, with an extension cable, i think so09:26
xfxfit's a hell of a lot better than the ~1m they are now09:27
mithroxfxf: pics?09:27
mithroxfxf: I think you are probably right09:27
xfxfnot sure there's much to take a picture of09:27
xfxfpower pack with ~1m cable09:27
*** rohitksingh has joined #timvideos09:36
mithroxfxf: I mean of how you are putting things in the case09:42
mithroxfxf: what standoff size are you using?09:42
xfxfi put the board in the case and screwed it in using the supplied screws09:42
mithroxfxf: hrm?09:43
xfxfi'm confuused as to your question09:43
mithroyou need standoffs between the board and the holes in the case09:43
xfxfokay, that's not going to be obvious to others09:44
xfxfi have one working fine without them09:44
xfxfi hope i haven't fried anything09:44
xfxfmithro, there's nothing about standoffs on the case page09:48
xfxfi'm utterly confused, what do you mean by 'standoffs'09:48
xfxfand where am i supposed to get them?09:48
mithroxfxf: http://apexfasteners.com/fasteners/images/categories/MaleFemaleStandoff.png09:48
xfxfi mounted it into the case like i'd mount any motherboard09:48
xfxfthe case already has raised bits09:49
xfxfthe case also doesn't come with any of those09:49
xfxfi'm lost why you'd want to add standoffs on top of those when those are good enough for normal matx motherboards09:55
mithroxfxf: I'm pretty sure a motherboard isn't designed to be directly mounted on those?09:59
xfxffairly confident it is, it's how most cases are these days10:00
xfxfwell, the tiny ones anyway10:00
xfxfthe case doesn't come with any standoffs10:01
xfxfthere are plastic standoffs with the hdmi2usb, but they're way longer then the screws provided, so won't work10:04
xfxfand they're female on both ends so also won't work10:04
xfxfi still think we need to 3d print cases for these things so all ports are exposed10:10
mithroxfxf: I ordered a bunch of standoffs to be delivered to your place (and a second copy to be delivered here)10:13
xfxfi'm not convinced they're needed for this case - nothing on the board is touching the case10:13
xfxfand they come with a clear plastic sheet with MATX holes already cut in it - i've just mounted the hdmi2usb on top of it as insulation10:14
xfxfgiven the plastic sheet is there, and there's no standoffs, i'm fairly confident these are designed to be used without standoffs10:14
xfxfespecially given the height of the board is aligned to the back open panel to where i'd expect it to be10:15
xfxfi.e. ~3mm up10:15

mithroxfxf: https://opsis.hdmi2usb.tv/getting-started/layout.html12:52
xfxfwhat are the plans for the SD card btw?12:58
xfxfand is it micro SDXC compatible?12:58
xfxfi'm also assuming both TOFE boards i got currently don't do anything?12:58
xfxfbecause as a prior VJ i'm pretty damned keen to play with the milkymist stuff at some point12:58
xfxfbut assume no firmware support yet12:59
mithroxfxf: it should work at pretty large capacities / high speeds but it doesn't have the extra pins of the newest standards12:59
mithroxfxf: just software :)12:59
xfxfso who is making the milkymist stuff work?  _florent_ ?13:00
xfxfobviously not critical for LCA, just personally curious13:00
mithroNobody at the moment13:16
mithroInsert developers here :-P13:17
mithroI didn't get a chance to look at the 30fps problem13:18
xfxfthat's fine, i've been building hardware and trying to organise venue/bump in logistic stuff tonight13:21
xfxfmithro: okay, possible issue that needs to be fixed - my pro cameras, being australian, won't do 720p60.  720p50 only.  they don't work with hdmi2usb with the 720p60 mode at all, no picture ever comes in14:07
xfxfand on 720p50 mode, it's not working properly either - i get a few frames and then it stops14:07
xfxfinput0: shows 1280x014:07
xfxfthen 0x014:07
xfxfis it possible to get your firmware to capture at 25fps - australia is 720p50, not 60, i can see problems having to put everything at 60 in terms of captured video looking a bit juddery14:08
xfxf+ i'm still dubious the uni doesn't have scan converters for their gear in each room which is locked to 5014:09
micolousPlus the lights will flicker14:10
xfxfyes, that too14:13
xfxfactually i'm pretty much going to say we need 25fps/50hz capture as a requirement14:13

CarlFKxfxf: your cables arrived, sans dog bites.23:06
xfxfre me asking about when you were leaving I was going to see if I could get some power cables express shipped to you23:19
xfxfbut I found a local vendor that wasn't too much more expensive so went that route23:19
