| mithro | xfxf: we can switch to 25fps, but its not going to happen before the hackfest | 00:05 |
|---|---|---|
| xfxf | at hackfest is fine | 00:09 |
| xfxf | I'm having multiple issues with the opsis's btw | 00:10 |
| xfxf | but we can look at it this weekend | 00:10 |
| mithro | xfxf: Can you please find repos and log bugs in the issue tracker? | 00:10 |
| xfxf | given its wed | 00:10 |
| xfxf | haven't had time | 00:11 |
| xfxf | but sure | 00:11 |
| mithro | xfxf: having stuff in the issue tracker ASAP would be really helpful if you can | 00:11 |
| mithro | ysionneau: ping? Did you ever end up working on any miniSpartan6+ stuff? | 00:11 |
| xfxf | understand, but I'm at "nothing is working properly and I don't know why", not "here are a number of steps to follow to make X occur" | 00:11 |
| xfxf | latter requires more time investment | 00:12 |
| xfxf | will do, just haven't had time yet | 00:12 |
| mithro | xfxf: thanks - It's expected there will be some bugs which need shaking out, the sooner we understand the problem the better | 00:13 |
| xfxf | nod, I'm going to guess you will have no time in the next two days | 00:13 |
| mithro | xfxf: maybe, maybe not | 00:14 |
| xfxf | we can reproduce Fri night | 00:14 |
| mithro | xfxf: I've been working from about 6pm till about midnight on stuff, if I can see the problem is easily repoed and I know an easy fix - then it might get done before Friday | 00:16 |
| CarlFK | mithro: might help to have some targets, like 1) plug in power, 2) turn on (is there a switch?) 3) plug in usb to linux box 4) flterm... 5) hit enter see HDMI2USB> prompt, 6) status, see the following: (expected status output for this case) | 01:55 |
| mithro | xfxf: can you make sure we actually have access to the podiums in the rooms? | 02:12 |
| xfxf | we won't. uni av always lock it down | 02:17 |
| xfxf | I suggest we ask in person on Monday rather than be difficult over email | 02:17 |

| mithro | xfxf: so the backplates don't work if you don't use a standoff | 06:34 |
| mithro | xfxf: I have 50 standoffs here now, and I sent a further 50 to your place | 06:34 |
| xfxf | okay, cool | 06:34 |
| xfxf | you may as well bring them with you instead of sending stuff | 06:34 |
| xfxf | given you're here in 2 days :) | 06:35 |
| mithro | xfxf: no - I had them sent from the US to you | 06:35 |
| xfxf | oh, right | 06:35 |
| mithro | xfxf: and the same to me | 06:35 |
| mithro | xfxf: just in case they didn't turn up here in time | 06:35 |
| mithro | xfxf: just working on getting a bunch of the faceplates now | 06:35 |
| xfxf | neat, ta | 06:37 |

| xfxf | i don't mind adding the backplates but i'm 100% they're not actually needed | 06:37 |
| xfxf | er, the standoffs, rather | 06:37 |
| xfxf | i'll add them if they're the only way the backplates fit | 06:37 |
| xfxf | also, can you bring that case i sent you up? | 06:38 |
| xfxf | i modified mine last night and it actually works fairly well | 06:38 |
| xfxf | as in, i'm using the PSU inside of it | 06:38 |
| xfxf | which is overkill but it means i have a barrel connector on the outside of the box | 06:38 |
| xfxf | instead of a cable hanging out | 06:38 |
| xfxf | might wire up a relay to the power button + ATX pins too so i can turn it on and off :) | 06:39 |
| mithro | xfxf: pic? | 07:02 |
| xfxf | can't, not home | 07:02 |
| xfxf | not really much to take a pic of | 07:02 |
| xfxf | it's the case i sent up to you with the hdmi2usb mounted inside of it with a few of the ATX cables modified to ensure it powers up + feeds power to the 6-pin pci-e connector | 07:02 |
| mithro | https://www.irccloud.com/pastebin/230CazR3/ | 07:03 |
| tpb | Title: Pastebin | IRCCloud (at www.irccloud.com) | 07:03 |
| mithro | xfxf: yeah, I want to put it on the cases page :) | 07:03 |
| xfxf | so you'll cringe at this | 07:03 |
| xfxf | but i looked at the diagram for your 6-pin pci-e connector | 07:03 |
| xfxf | and the specs for ATX | 07:03 |
| xfxf | and discovered if you plug in a 4-pin ATX cable backwards into your connector it works | 07:03 |
| xfxf | i am not sure you want to recommend that :) | 07:03 |
| xfxf | same voltage, pins are just reversed | 07:04 |
| xfxf | pretty much that + pulling out two of the pins on the ATX cable that comes with it to wire the power pin to ground | 07:04 |
| xfxf | i also noticed the rpi2 has gstreamer stuff for its hardware h.264 encoding | 07:07 |
| xfxf | i'm tempted to try mounting a rpi2 in the same case as there's room and seeing if i can do any automated encoding for LUG's | 07:07 |
| xfxf | even if the encode takes half a day it'll probably be sufficient for an automated solution | 07:08 |
| thaytan | xfxf, the rpi can do full-hd h.264 encode in real time | 07:09 |
| xfxf | oh, neat, so there's legs in that style of solution then | 07:09 |
| thaytan | USB bandwidth may suck - not sure if it can actually do the full 480Mbit/s USB2 | 07:09 |
| xfxf | I thought the rpi2 was better in that regard | 07:10 |
| xfxf | I know the rpi1 was poor from personal experience | 07:10 |
| thaytan | it has more CPU to service the USB interrupts | 07:10 |
| thaytan | but the ethernet is still hanging on the same USB | 07:10 |
| xfxf | oh, they didn't move away from that, shame | 07:10 |
| thaytan | so it depends where you're putting your encoded results | 07:11 |
| thaytan | any useful destination is probably still on that USB | 07:11 |
| xfxf | well, if not a rpi2, are there other similar boards that have gstreamer supported h.264 encoding? | 07:11 |
| xfxf | even if they cost more | 07:11 |
| thaytan | freescale boards can, or minnowboards can do it via VAAPI | 07:12 |
| thaytan | xfxf, I'm just making general observations - I'm not sure how much of the USB bandwidth the JPEG capture/encode wants to use | 07:12 |
| xfxf | oh, its v useful info, thank you | 07:13 |
| xfxf | and nod, valid points | 07:13 |
| xfxf | these are ideas I'll explore after LCA i'm yet to attempt | 07:13 |

| mithro | xfxf: It looks like the clk_freq on the Opsis is set to 50MHz rather then 75MHz - but I'm unsure if that is related or not | 10:00 |
| mithro | xfxf: I think this might be related to https://github.com/timvideos/HDMI2USB-misoc-firmware/issues/20 | 10:01 |
| tpb | Title: Get better performance with encoder and quarter rate DDR phy · Issue #20 · timvideos/HDMI2USB-misoc-firmware · GitHub (at github.com) | 10:01 |
| xfxf | ah, is there huge variance between the atlys and opsis firmware? | 10:02 |
| xfxf | i assumed they'd be mostly the same | 10:02 |
| mithro | xfxf: no, there is only a small variance - they are 90% the same | 10:02 |
| mithro | One of the big differences in the memory controller though | 10:02 |
| xfxf | right, because the atlys firmware is working great - outside of it being locked to 30fps and the wierd issue with red + other minor things i reported | 10:02 |
| mithro | The Atlys has DDR2, while the Opsis has DDR3 | 10:03 |
| xfxf | oh, neat | 10:03 |
| xfxf | does that mean we can do things like pass 1080p60 through but capture at 30? | 10:03 |
| mithro | xfxf: not really, the IO pins on the FPGA doesn't toggle fast enough for 1080p60 | 10:05 |

| mithro | ysionneau: that was back before you did you had a miniSpartan6+ - so was wondering if you had replicated it at all | 12:24 |
