| tumbleweed | mithro: can I put a backport of my hdmi2usb-mode-switch package in ppa:timvideos/fpga-support ? It's a little different to your one | 00:24 |
|---|---|---|
| CarlFK | tumbleweed: what's the difference? | 00:27 |
| tumbleweed | it only uses udev, not the unbind helper | 00:28 |
| tumbleweed | the dependencies are a lot saner | 00:28 |
| tumbleweed | and a few other subtle things | 00:28 |
| tumbleweed | most were upstreamed, but the PPA package is old | 00:29 |
| CarlFK | currently the PPA doesn't have a hdmi2usb-mode-switch package ? | 00:35 |
| tumbleweed | it does, but it won't do the right things | 00:37 |
| tumbleweed | I think | 00:38 |
| tumbleweed | (for our ansible stuff) | 00:38 |
| CarlFK | I'd prefer to keep things 'best' for LCA until after LCA | 00:39 |
| tumbleweed | what does that mean? | 00:39 |
| CarlFK | good Q... I'm struggling to figure out where it fits in the food chain | 00:40 |
| tumbleweed | I don't think there's anything better about what's currently in that PPA package. But mithro might, because he did it that way | 00:40 |
| CarlFK | hdmi2usb-mode-switch is used for flashing firmware. which should be done days/weeks before the show. right? | 00:41 |
| tumbleweed | its udev package is also used to set up alias devices, and permissions | 00:41 |
| xfxf | i'm fine using an improved package, just poke me so i can test it | 01:07 |
| CarlFK | xfxf: is the laptop hdmi capture projector opsis going to be near the lectern? | 01:17 |
| xfxf | yes, same as usual | 01:17 |
| CarlFK | laptops? | 01:18 |
| CarlFK | er | 01:18 |
| CarlFK | xfxf: what sort of system do you plan on hooking the opsis to? | 01:18 |
| xfxf | The venue's system? Not sure I understand the Q | 01:18 |
| CarlFK | what will the opsis usb cable plug into | 01:19 |
| mithro | tumbleweed: Sure I guess? | 01:19 |
| xfxf | A laptop | 01:19 |
| xfxf | Same as last LCA | 01:19 |
| CarlFK | k | 01:19 |
| CarlFK | I really like having a SBC in the same box. but I also have bigger boxes that have room and a place to mount it. | 01:20 |
| xfxf | yes I bought a couple of rPI 3's and power adapter and started looking at 3D printing a mounting kit for it to fit inside of the opsis cases | 01:20 |
| CarlFK | and also I have no idea how to properly install stuff on it. | 01:20 |
| xfxf | But not for LCA, prefer to concentrate on other things | 01:20 |
| CarlFK | according to the people in the room here, not gig e, and even if it is it is on a crappy usb2 buss so you won't get more than a few 100 | 01:24 |

| tumbleweed | CarlFK: which PPA can we put a voctomix-outcasts in? | 01:27 |
| tumbleweed | and voctomix for that matter | 01:27 |
| tumbleweed | we had one for dvswitch, we should probably have one for voctomix | 01:30 |
| CarlFK | that sounds ok | 01:31 |
| * tumbleweed isn't an admin, though :) | 01:31 | |
| tumbleweed | so someone else must create it | 01:31 |
| CarlFK | trying... | 01:36 |

| CarlFK | I don't mind putting -outcasts in my PPA, for my use and testing and maybe LCA don' | 01:39 |
| CarlFK | t care :p | 01:39 |
| CarlFK | but I have to go to dinner now. so never mind that | 01:40 |
| CarlFK | xfxf: get odroid C2s $40 each + $5 for the micro sd | 01:45 |
| CarlFK | xfxf: or whatever tumbleweed DC vid found that is an x86 based thing. | 01:46 |
| CarlFK | anway, Imm off for dinner - see ya | 01:46 |

| xfxf | deeprave: i'm keen to start integrating the hdmi2usb daemon you wrote into our toolchain for LCA (mostly so we can log what the device is doing in an automated way), is it ready to be used for this use-case? | 03:32 |
| xfxf | immediate usecase will probably be wrapping it up via systemd & using stdout/stderr from it as a simple log mechanism | 03:33 |
| tumbleweed | you want to log what people did with the opsis? | 03:34 |
| xfxf | it's so we have more than empirical evidence when things don't work; i.e. actual useful information from production usage that will help with solving issues | 03:34 |
| xfxf | i.e. we have a bunch of boards at the moment that don't work properly in various ways, all we have are scribbled notes on top of each device with vaguely describe what we *think* happened. obviously during an event you don't want to sit there and hold up a talk and debug exactly what's going on, you just swap it out and on the show goes | 03:35 |
| xfxf | and of course, these problems seem difficult to replicate in non-production | 03:35 |
| tumbleweed | yeah | 03:35 |
| xfxf | but having the debug info off the opsis will help somewhat | 03:35 |
| xfxf | having this in place is a pretty hard requirement set by mithro :P | 03:36 |
| xfxf | so that's probably my biggest aim | 03:36 |
| xfxf | we started working on a supervisor like setup last LCA for monitoring etc but systemd very likely solves it better | 03:36 |
| xfxf | i'm not sure how much i trust systemd to do this, but if you guys have used it successfully then it increases my confidence | 03:37 |
| tumbleweed | what's not to trust about it? | 03:37 |
| tumbleweed | init systems have to be pretty robust, or everything goes pearshaped | 03:38 |
| xfxf | the usual rantings of those who are staunch init fans :P i use it myself fine, and i'm already far further along drinking the koolaid given i'm a heavy docker user | 03:39 |
| xfxf | yeah, indeed | 03:39 |
| xfxf | i just tend to take a super conservative view with AV systems, given the scope of what can go wrong | 03:39 |
| xfxf | so i'm slightly hesitant | 03:39 |
| xfxf | but logically it's fine | 03:39 |
| tumbleweed | for the job of restarting something if it dies, I'd trust it more than anything I whipped up myself | 03:39 |
| xfxf | indeed, agree | 03:39 |
| tumbleweed | it's the corner cases around that were things break | 03:39 |
| tumbleweed | i.e. hardware that doesn't come back on its own | 03:40 |
| xfxf | yes, i suspect our use of it for what we're doing probably falls into corner case territory | 03:40 |
| cr1901_modern | My main complaint about systemd, which has fortunately not quite come to pass yet, is that applications start hard depending on it and reducing portability b/c Linux is the One True Unix. And my complaint about Linux is that it's too complicated and I can't confidently grok the source anymore. | 03:40 |
| tumbleweed | cr1901_modern: yeah, I think we all worried about that, but haven't seen much evidence, yet | 03:41 |
| xfxf | didn't somebody port systemd to one of the *BSD's? | 03:42 |
| xfxf | not that this is an ideal solution, but it probably is one ;-P | 03:42 |
| tumbleweed | upstream didn't want the patches | 03:42 |
| cr1901_modern | ehhh... it's a shim | 03:42 |
| xfxf | heh! | 03:42 |
| cr1901_modern | I'm fairly okay reading, say NetBSD's source code, by contrast (although yes, there is a learning curve to the BSD source tree layout, I don't think it's any worse than Linux) | 03:42 |

| deeprave | @xfxf: re hdmi2usbd - had some fixes to go in, just not sure whether i've pushed them to github yet. Remind me again after Thurs this week, won't have much time until then (and next weekend looks pretty fubar atm too :-/). | 05:17 |
| CarlFK | What i the plan for streaming? I am not really sure what was used last year | 07:22 |
| jea | i'll look into streaming. not too sure what it will be yet | 08:31 |
| xfxf | flumotion - mithro and micolous will know more | 08:46 |
| mithro | I think last year we just used some gstreamer pipelines directly to YouTube | 08:47 |
| jea | that does sound vaguely familiar | 08:50 |
