| Saviq | sophie on damage reporting… I wonder how important that is when hardware accelerated encoding is used… In the best case scenario, there should be zero copy involved, and I imagine the hardware encoder is quite good at "detecting damage"… like, that's most of what video compression is about? | 07:30 |

| alan_g[m] | Saviq shouldn't a successful "close snaps" close the snap branch? https://github.com/MirServer/mir-kiosk-kodi/pull/31#issuecomment-1160142878 | 08:36 |
| Saviq | > Channel 'edge/pr31' for 'mir-kiosk-kodi' is now closed | 08:37 |
| Saviq | So. Hmm. | 08:38 |
| alan_g[m] | Oh, there's no version there | 08:39 |
| Saviq | Yeah it is closed | 08:39 |
| Saviq | The branch will be garbage collected after some time | 08:39 |
| Saviq | And if you refresh / install, you'll get `edge` | 08:39 |
| alan_g[m] | 🎆 | 08:39 |
| alan_g[m] | Saviq is this intentionally empty? https://github.com/MirServer/mir-kiosk-x11-snap/pull/15 | 08:46 |
| Saviq | No, fixing | 08:47 |
| Saviq | alan_g fixed, I confused GH before | 08:50 |
| alan_g[m] | There does seem to be a lot of repetition | 08:52 |
| Saviq | Less now, but a lot still, indeed. | 08:57 |
| Saviq | I don't think there's a way to reduce it much more. Each repo will need a workflow one way or another. Maybe I can put better defaults in the action so unless there's something special about a particular repo (like `snap: mir-kiosk-x11`), the defaults would do | 09:00 |
| alan_g[m] | Saviq this needs fixing https://github.com/MirServer/ubuntu-frame-vnc/pull/1#issuecomment-1160155235 | 09:10 |
| sophie-w | <Saviq> "sophie on damage reporting… I..." <- Does VNC have good compression? My impression was damage would greatly help it but I haven't measured that | 09:10 |
| Saviq | > Saviq this needs fixing https://github.com/MirServer/ubuntu-frame-vnc/pull/1#issuecomment-1160155235 | 09:10 |
| Saviq | Yeah, I'll just drop the PR… I'm working on that snap right now | 09:10 |
| Saviq | > Does VNC have good compression? My impression was damage would greatly help it but I haven't measured that | 09:10 |
| Saviq | It can do h264, provided both the client and server can do it. So it still may be worhtwhile for jpeg (I _believe_ the default compression) | 09:10 |
| Saviq | And well, even with h264 it may be worthwhile if we can't achieve zero-copy | 09:10 |
| alan_g[m] | sophie-w: I'd guess that it depends on the actual path taken. It may not help the "best case" but it should help others. | 09:12 |
| Saviq | Indeed | 09:12 |
| alan_g[m] | Does this also need updating for the snapcraft changes? https://github.com/MirServer/ubuntu-frame/pull/44 | 09:39 |
| Saviq | <alan_g[m]> "Does this also need updating for..." <- Yeah will rebase them all, to but also probably make what's using it merge tips of the relevant projects | 09:45 |
| -GitHub[m]:#mir-server- **[MirServer/mir]** bors[bot] merged [pull request #2473](https://github.com/MirServer/mir/pull/2473): ci: add armhf builds | 09:46 | |
| alan_g[m] | Saviq easy review: https://github.com/MirServer/mircade/pull/10 | 10:50 |
| RAOF | Best case, sending damage dramatically reduces the computational complexity of whatever encoding you're doing, and video encoders hate encoding the sort of super-high-frequency data that desktops consist of. | 10:52 |
| Saviq | Right, but that assumes the encoder can actually consume damage data, which I don't think will be the case for a hardware encoder? | 10:53 |
| Saviq | I may also be wrong ¯_(ツ)_/¯ | 10:54 |
| Saviq | Like, I mean, for what the encoders get used to, damage data will rarely be available… one of the things that they need to find is the damage, so I would be surprised if there was API to supply damage from the outside. | 10:56 |
| Saviq | > So looking into abigail (for ABI stability reasons) there are two options: | 11:10 |
| Saviq | alan_g in case you missed this ^, what would be your preference? | 11:10 |
| Saviq | > <@saviq:matrix.org> So looking into abigail (for ABI stability reasons) there are two options: | 11:11 |
| Saviq | > 1. we compare deb packages (so probably grab the ones from Ubuntu devel) against what we build in CI | 11:11 |
| Saviq | > 2. we check in an XML representation and compare that against the .so we build | 11:11 |
| Saviq | Now with a better reference | 11:11 |
| alan_g[m] | I think 1 as stated has a problem as soon as we've released an ABI change to ppa:mir-team/release (should that be the reference?) | 11:13 |
| Saviq | It could be, yes. There should be very little delay between release and devel, but you're right, during freezes it could mess with us | 11:14 |
| alan_g[m] | I've a mild preference for not relying on pulling binaries off the internet though. Having a source of truth contemporaneous with the code could be useful working with historic releases | 11:19 |
| Saviq | Yeah the arguments for looking at the PPA are, AFAICT: | 11:35 |
| Saviq | - not having to maintain another ~symbols file | 11:35 |
| Saviq | - it's verifying the real thing | 11:35 |
| Saviq | Not that they're arguments enough | 11:35 |
| alan_g[m] | Hmm. More "random" wlcs test failures. Time to investigate... | 11:39 |
| Saviq | I'm inclined to blame qemu for this. They're all arm* failures, which run emulated | 11:43 |
| alan_g[m] | Maybe, but that could also simply be exposing an underlying problem | 11:44 |
| Saviq | I'll try and get them to fail on hardware | 11:45 |
| alan_g[m] | My usual tactic is to run the test in a loop until it fails. Even on different arch that often exposes a fail | 11:47 |
| Saviq | Yup, I sometimes add a `stress …` for good measure | 11:52 |
| alan_g[m] | Me too | 11:52 |
