| techman83 | jea: no perl! blasphemy! | 01:04 |
|---|---|---|
| * techman83 got hired as a python developer | 01:04 | |
| techman83 | jea: I'll be about at the conference if you want to pick my brain, I've actually wanted to re-develop eventstreamr in Python. | 01:07 |
| jea | techman83: haha. perl is not a problem, just that I don't know enough of it to do useful things with it | 01:08 |
| techman83 | jea: though for data gathering + metrics, it might worth using something like prometheus and just write some custom exporters. No need to write a whole stack then. | 01:08 |
| jea | I have a mostly rewritten version of eventstreamr in python, but it hasn't been used properly yet. most of the bits that I didn't convert can go away now too due to not using dvswitch | 01:09 |
| techman83 | jea: That's the main problem, not enough perl devs. | 01:09 |
| techman83 | jea: nice | 01:10 |
| jea | and yes, prometheus is the plan for the monitoring. i got it setup the other day, now i just need to generate the data! | 01:10 |
| * techman83 dances | 01:10 | |
| jea | but first i need to work out why these numbers are complely off. seems like it is not really using a long... | 01:11 |
| xfxf | techman83: turned to the dark side? ;) | 01:18 |
| xfxf | congrats on new job btw | 01:18 |
| techman83 | xfxf: haha, yeah. A job offer popped up. Requirement was that I learn Python. | 01:19 |
| techman83 | Thanks. It's much more interesting and far less soul destroying than my previous job! | 01:19 |

| mithro | xfxf: What do the numbers in the cell means? | 02:22 |
| xfxf | explained up the top | 02:22 |
| mithro | xfxf: I would have never seen that myself :-P | 02:23 |
| xfxf | it was the easiest way to help identify patterns | 02:23 |
| xfxf | a 2 so far always means it works but only after a power cycle | 02:24 |
| xfxf | do i have to check every single cable. this shit is tedious | 02:24 |
| xfxf | surely redmere + white/std is enough? | 02:24 |
| xfxf | mithro: i think you just moved values in the column i'm currently testing in... | 02:27 |
| mithro | xfxf: Oh sorry - I rearranged it to be input first, then cable type | 02:27 |
| xfxf | also the order you've stuck things in is not how i'm testing them | 02:27 |
| xfxf | i'm doing different cables on both inputs, not power cycling + test, then power cycle + test each time | 02:28 |
| xfxf | er rather, above is confusing | 02:28 |
| xfxf | i'm doing: take a cable, plug it in to input0, see what happens, power cycle device if it didn't work, see what happens, then repeat on input 1. then onto a new cable | 02:29 |
| mithro | xfxf: I need to be able to rearrange the table so I can understand the data - is there a way to do that? | 02:29 |
| xfxf | not sure, i just want this to flow in how i'm doing things so i don't make data entry errors | 02:30 |
| xfxf | pretty sure input0 is boned on this board anyway | 02:30 |
| mithro | xfxf: I added a test-order column which lets me quickly switch back and forth between the two sorting orders | 02:31 |
| xfxf | looking at this i'm pretty sure i can reduce the testing to 1 redmere cable, 1 white cable, on all devices, on both input0/input1, with the power cycle/non power cycle test | 02:31 |
| xfxf | np | 02:31 |
| xfxf | pls confirm above | 02:31 |
| xfxf | i assume i'll be able to do a subset of devices too which are acting different (i.e. mDP dongle vs HDMI port on my mac, versus the xa20) | 02:32 |
| mithro | xfxf: Looking at it at the moment | 02:32 |
| xfxf | feel free to re-sort, i'll go outside for a sec | 02:32 |
| mithro | I was sure there was a way to make the sort order specific to the user with the "views" stuff | 02:34 |
| mithro | but I don't have the mental capacity to figure that out again | 02:34 |
| mithro | xfxf: Looking at the spreadsheet, there is one weirdness | 02:35 |
| xfxf | which is? | 02:36 |
| xfxf | outside of the xa20's always working | 02:36 |
| mithro | xfxf: the "Lenovo W530 - mDP" was different on the Blue/White Redmere cable? | 02:36 |
| xfxf | it was? let me look | 02:37 |
| mithro | xfxf: I'm wondering if that is just an entry error or something | 02:37 |
| xfxf | oh | 02:38 |
| xfxf | right | 02:38 |
| mithro | xfxf: You written "same behaviour as blue 3ft redmere below" | 02:38 |
| xfxf | so i suspect it's the same problem | 02:38 |
| xfxf | except the cable might have worked once | 02:38 |
| xfxf | both are problematic | 02:38 |
| xfxf | oh wait no | 02:39 |
| xfxf | both are meant to be 3 | 02:39 |
| xfxf | fixed | 02:39 |
| mithro | xfxf: Can you see if you can reproduce that at all? I don't think we have ever seen a difference between redmere cables? | 02:39 |
| *** paradisaeidae_ has joined #timvideos | 02:39 | |
| xfxf | sure | 02:39 |
| xfxf | this is again, the most tedious shit ever :P | 02:39 |
| mithro | xfxf: Yeah sorry, we really need some minions :( | 02:40 |
| xfxf | is there anybody else we could grab? | 02:41 |
| xfxf | i really should be working on this monitoring stuff.. it is thu arvo | 02:41 |
| xfxf | somebody def should test all boards though | 02:41 |
| mithro | xfxf: Can we extract the following extra data for each cell on this board | 02:42 |
| mithro | xfxf: If you are seeing the "dvisampler0: IDELAY busy timeout" | 02:43 |
| mithro | xfxf: If we are seeing the "pixelclk" value | 02:43 |
| xfxf | no | 02:43 |
| xfxf | wtf | 02:43 |
| mithro | xfxf: If we are seeing the WER | 02:43 |
| xfxf | the redmere cable works on input0 sometimes? | 02:43 |
| xfxf | it seems random | 02:43 |
| mithro | I think they are all in your notes already | 02:43 |
| xfxf | i'm seeing errors | 02:43 |
| xfxf | no idea busy timeout | 02:43 |
| xfxf | wait, nm, i am | 02:43 |
| mithro | xfxf: You okay with me added extra columns under each device and putting that there? | 02:44 |
| xfxf | um, i guess, how much more confusing is this going to be? | 02:44 |
| xfxf | okay, so occasionally when i unplug it / plug it back in, it works | 02:45 |
| xfxf | both redmere cables | 02:45 |
| xfxf | i don't even know how to record this data anymore, this is too confusing to display two dimensionally | 02:45 |
| xfxf | mithro i'm struggling dealing with representing sane test data on what appears to be a faulty board that doesn't always do the same thing | 02:49 |
| xfxf | i've marked it as '3' and added notes | 02:49 |
| mithro | xfxf: Looking at the data so far, It looks like there is an issue with the IDELAY stuff on this board in Input 0 of this board | 02:50 |
| xfxf | okay, well, this data is for you, so you tell me if what i'm providing is enough | 02:50 |
| xfxf | i'm going to try and rope somebody else in to test all ~17 or whatever boards but we need repeatable test instructions first | 02:51 |
| xfxf | i don't think me spending the rest of today doing this is a good idea considering everything else i need to be on top of | 02:51 |
| xfxf | my next steps should be trying a new board, continuing along the existing board with new devices, something else? | 02:52 |
| mithro | xfxf: So if IDELAY timeout occurs, then a high WER rate and the input not working is expected | 02:54 |
| xfxf | ok, answer to Q above? | 02:55 |
| mithro | Hold on, writing some stuff | 02:56 |
| xfxf | i really want to continue the monitoring s/w (given the extra complexity there now) so want to progress on this rapidly | 02:56 |

| mithro | _florent_: The one that is currently working on the TV has that warning | 10:32 |
| xfxf | mithro: you're way more on top of what's required for streaming than I am, can you instruct micolous on what you'd like him to do over the next couple of days when he arrives? | 10:35 |
| xfxf | from my POV i want to make sure anything he used to do the YT streaming last year is committed up to a repo, and there's a handoff to jea before the conf starts | 10:35 |
| mithro | He probably knows better then I do what the current state of it is | 10:36 |
| xfxf | i'd imagine there'll be some integration with the ansible stuff tumbleweed/CarlFK are working on, so it's integrated correctly into the systemd foo they're doing + the right bits are on the machine | 10:36 |
| mithro | NFI on that part | 10:37 |
| xfxf | me either, poke tumbleweed, chat with micolous tomorrow (he arrives anytime soon) about what of his YT/gstreamer streaming stuff needs to end up on the machines | 10:39 |
| xfxf | debconf use icecast normally, correct? | 10:39 |
| tumbleweed | yep | 10:41 |
| mithro | xfxf: I seem to recall that nothing was run on the systems locally - everything was run on a system in the NOC and it just connected to voctomix's streaming port remotely | 10:41 |

| kflux | hi guys | 16:05 |
| kflux | i have the numato opsis with all the extension boards | 16:06 |
| kflux | i am not a developer though | 16:06 |
| kflux | i supported the project hoping for a videomixer firmware for it | 16:06 |
| kflux | i read that there was a SoC project to make such a firmware | 16:06 |
| kflux | i was wondering what the status is on that | 16:07 |
| kflux | what is the current funtionality of VideomixerSoC and how to i put it onto my opsis | 16:08 |
| kflux | the "documentation" is very confusing for non devs | 16:48 |

| its_only_me | hello | 20:47 |
| its_only_me | quick question about crowdsupply campaign: it is a great device and i wonder what is throughput of that expansion slot. I would like to do hdmi switch 2x8 for example (routing 2 signals between 8 outputs), do you think it is possible ? | 20:49 |
| tumbleweed | CarlFK: o/ | 22:12 |
| micolous | You're awake? I'll come down then | 22:13 |
| tumbleweed | yep | 22:13 |

| micolous | I've just been trying to get the YT stuff running again, without success. I think there are rate limits on this network because "uploading to youtube" has the same traffic profile as "uploading to p2p" | 22:14 |
| micolous | its_only_me: there's one person who can answer that with certainty, and I think he's asleep | 22:15 |
| *** CarlFK has quit IRC | 22:58 | |
| tumbleweed | xfxf: will you try to find out the story with the network? | 23:12 |
| *** its_only_me has quit IRC | 23:16 | |
| xfxf | tumbleweed: emailed him | 23:19 |
| mithro | kflux: Sorry about that, the board is really only suitable for developers/power users at the moment, we are slowly working towards making it easier for non-developers but it still needs a lot more effort | 23:55 |
