Frields' 14:00:20 .hello catanzaro 14:00:22 mcatanzaro: catanzaro 'None' 14:01:51 * stickster waits for the crowd to arrive... in the meantime, o/ michael 14:02:02 o/ stickster 14:02:05 hello! 14:02:12 #chair mcatanzaro kalev 14:02:12 Current chairs: kalev mcatanzaro stickster 14:02:15 o/ 14:02:26 \o/ 14:02:32 I see wtay is here for the PulseAudio discussion 14:02:45 \o. 14:02:50 Hi Wim! 14:03:27 Hey everyone 14:03:34 Also patrakov 14:03:42 hi 14:04:10 \o :-) 14:04:31 .hello mclasen 14:04:32 mclasen___: mclasen 'Matthias Clasen' 14:04:43 #chair mclasen___ rdieter_work 14:04:43 Current chairs: kalev mcatanzaro mclasen___ rdieter_work stickster 14:04:53 Let's get started 14:04:59 #topic Default applications 14:04:59 .hello rdieter 14:05:00 rdieter: rdieter 'Rex Dieter' 14:05:01 hola 14:05:05 #chair rdieter 14:05:05 Current chairs: kalev mcatanzaro mclasen___ rdieter rdieter_work stickster 14:05:12 o/ Rex :-) 14:06:34 #info mcatanzaro dropped proposal for dropping Evolution + Boxes for now. Currently we have added Logs, dropped Bijiben, and propose to keep Shotwell and Rhythmbox around until Photos and Music are ready to move into the set of upsream core modules. 14:07:12 First, are there any objections to Logs/Bijiben changes? If so, now's the time to say so :-) 14:07:29 I was going to comment on this, since I've heard a bit of chatter regarding the 'workstation aligns to upstream gnome' push 14:07:47 please 14:08:01 "more or less aligns" 14:08:03 it might be worth stressing that this is actually an alignment that we're doing on both sides: we've made changes on the upstream gnome modulesets to align better with whats in the workstation 14:08:16 so it is not just changes on the fedora side to follow the whims of upstream 14:08:37 just wanted to clarify that, for the record 14:08:58 Indeed, I moved lots of apps into GNOME core to match what Fedora is shipping. 14:09:07 mclasen___: mcatanzaro: Any examples you want to include? (I'm in favor/agreement, ftr) 14:09:28 cheese, file-roller, gedit, gnome-characters, gnome-clocks, gnome-initial-setup, gnome-logs, gnome-maps, gnome-software, gnome-weather 14:09:44 :-) noted! 14:10:11 We're basically trying to make the upstream modulesets "sane" 14:10:25 #info Alignment between Workstation and GNOME upstream is a two-way street -- both projects have done some work to better align 14:10:26 As distros could not reasonably do anything with the previous ones. 14:10:30 you've also pushed a bunch of immature apps back to a new 'incubator', right ? 14:11:17 Yes, I'm using "incubator" for stuff that we want to be in core, but which we think are not quite ready yet (gnome-music, gnome-photos, gnome-calendar, gnome-boxes for now, gnome-dictionary). 14:11:51 Kind of a compromise between plans and reality. 14:12:28 This makes sense to me too. Shall we knock out the Shotwell and Rhythmbox issue before we bore the PA guys to death? :-) 14:13:02 as I've suggested on the list recently, we should make some concrete criteria for when to move music and photos (and boxes) back out of the incubator 14:13:13 #idea mclasen noted we should push for Music + Photos to replace RB + Shotwell in F25, and have criteria for that replacement. 14:13:37 I believe we had some discussion around such criteria for photos at some point 14:13:42 The criteria should probably be a subset of what's on https://wiki.gnome.org/Apps/Music/Roadmap and https://wiki.gnome.org/Apps/Photos/Roadmap 14:13:46 things like editing, import, export 14:14:00 some of which have been addressed already 14:14:20 I don't think we should set the criteria at this meeting, though. :) 14:14:46 no 14:14:56 mcatanzaro: As our resident proponent for All Things Default App, would you be willing to put together a first shot at a critical list of criteria for the mailing list? 14:14:57 lets move on, and do criteria on the list 14:15:01 mclasen___: agreed 14:15:19 stickster: Yeah, but maybe not this week, I'll add it to my to-do list. 14:15:24 +1 move on 14:15:31 mcatanzaro: I think it would be safe to do for 4 weeks out 14:16:11 #action mcatanzaro put together a first shot at criteria for Music + Photos default app swapout in F25 14:16:19 moving on... 14:16:25 #topic PulseAudio and flat volumes 14:16:58 So there are essentially two questions we are still stuck on IIUC... 14:17:11 1. Is it reasonable to stick with the current situation of disabled flat volumes for F24? 14:18:04 2. What is the plan for volume control in the near future (toward F25/GNOME 3.22) and how it affects developers, users, and other pieces of the system UI? 14:18:56 1. No working alternative has been implemented upstream so far 14:19:18 * stickster notes that the change for (1) was made based on Wim's input, but it's not irreversible, nor intended to dismay or marginalize the PA maintainers 14:19:27 I think for 2. most of the gui is built around non-flat volumes.. 14:19:39 1a. GNOME guys are against per-application volume control anyway and so conveniently avoid the question 14:19:53 you have the global volume on top, the per app volume as a volume slider in the apps 14:20:25 wtay: prpopnents of flat volumes want you to reinterpret this UI 14:21:09 the in-app slider, according to their opinion, is supposed to represent the absolute volume of that app, and the "master" is just a convenient handle for moving all app sliders 14:21:23 I think we can all agree that giving flat volumes to all apps is a bad idea 14:21:27 one important thing to note might be that Ubuntu ships with non-flat volumes, which means that this is what a lot of app developers target as well 14:21:38 on linux.org.ru such reinterpretation was called 'logic from mars", i.e. completely artificial and foreign 14:21:42 kalev: There are a number of distros that do likewise 14:22:01 kalev: not only ubuntu, also arch and opensuse 14:22:29 patrakov: I think we can leave the heated rhethoric out of this discussion 14:22:34 patrakov: Let's please refrain from assigning motives or slinging rhetoric please 14:22:53 we are here to discuss the roadmap ahead and use that to decide the right thing to do for Workstation 14:23:25 I believe gnome would prefer to move to a role based volume design 14:24:37 wtay: yes, see their roadmap: https://wiki.gnome.org/Design/SystemSettings/Sound 14:24:43 wtay: would that mean that some apps get to manipulate the user-set session volume, and some don't? 14:24:45 I wonder what a "role-based volume design" is. :) 14:24:59 * stickster is not really clear on what this means from user POV... speaking as a user and a non-dev 14:25:32 * mclasen___ sees if he can get hadess over here to talk about gnomes volume control desires/plans 14:25:39 it means a volume for "media" "notifications"and "alarms" 14:25:50 stickster: link above. although it omits details how foreign apps such as vlc (which have their own in-app volume slider) should behave in gnome environment 14:25:58 so all media apps have the same volume slider, basically 14:25:58 what I'm interested in, is the any estimate or time-frame to address the issues behind our wanting to (temporarily) disable flat volumes 14:26:20 * stickster skims through the page 14:27:25 way, patrakov: we should really bring in the relevant people here instead of second-guessing old design mockups 14:27:52 to me, that addresses most directly question 1, and how that affects future decision-making 14:29:09 in any case, some (non gnome) apps would want to control the volume themselves and then we likely don't want to give them flat volumes 14:29:30 like browsers 14:30:13 wtay: mcatanzaro: Does that put us back in the situation where browser plugins can surprise (or hurt) users, or damage their hardware? 14:30:43 stickster: why "back"? 14:31:04 stickster, not if we disable flat volumes 14:31:13 Ah, OK 14:31:44 stickster: I think wtay is proposing that apps that understand flat volumes can opt-in to the current behavior, but by default apps would not be able to raise the system volume. 14:31:58 So that would avoid the problem we currently have where YouTube keeps setting the system volume to 1. 14:32:05 if there is a mechanism to block some apps from using flat volumes, that would also avoid loud surprises 14:32:17 mcatanzaro: Thanks, that's what I wasn't clear on. 14:32:22 wtay: there was a patch for that in pulseaudio archives 14:32:47 I think it should be opt-in rather than opt-out, because reality is most apps are developed on Ubuntu and app developers don't understand or expect flat volumes. 14:32:56 I would like the user to opt in on what apps can use flat volumes 14:33:00 wtay: it was rejected because it leads to inconsistent UI in pavucontrol (no way to determine visually whether the slider represents absolute volume or not) 14:33:40 hadess: hey, any input from you on this ? 14:34:02 mclasen___, i don't really care either way, because i want to remove application volumes altogether :) 14:34:05 wtay: search for "[RFC] Per-client flat-volumes control" 14:34:12 but yes, some apps with and others without flat-volumes is very confusing in mixer apps 14:34:13 * stickster notes, no one has addressed rdieter's question about timeframes 14:34:33 stickster: maybe that means there isn't any time-frame (yet) 14:34:47 mclasen___, that's one of the goals of the redesign: https://wiki.gnome.org/Design/SystemSettings/Sound 14:34:58 wtay: does that mean we won't get such an opt-in api for clients ? or do we need to add more api for mixers to learn about clients choices ? 14:35:23 mclasen___, per-application class volume, so your video playback apps have all the same volume, and they can't raise it themselves on startup 14:36:03 mclasen___, if it were me, I would not let clients opt-in 14:36:04 And the reason for asking about timeframe is mostly about seeing whether disabling flat volume is likely to be swapped out for some other change within one release, or not. It sounds to me like this won't be solved for some time yet, and we're not playing quick flip-flop with users by disabling FV now. 14:36:07 hadess: which sounds like non-flat-volume-y to me ? or maybe I'm entirely confused now 14:36:09 can't raise it? surely there must be a volume control in a video player? 14:36:27 alexlarsson, "on startup" 14:36:50 ok, so it can't restore its old saved volume in case some other video player changed inbetween? 14:36:52 "stupid application, thinking it can remember its volume better than pulseaudio" 14:36:53 or somthing? 14:37:10 hadess: on pulseaudio side, there is no way to determine whether something is done "on startup" or based on user input 14:37:11 alexlarsson, it doesn't have its own volume, there's a single volume for the class of application 14:37:12 makes sense, although a bit hackish 14:37:24 hadess: yeah, but the app might not be aware 14:37:36 patrakov, details 14:38:29 the role based volume would be more like flat volumes, you get only 1 slider 14:39:00 wtay, either that, or it means that the volume inside the app is always relative to the system/class volume 14:39:08 right 14:39:13 are the per-class volumes absolute or relative to some master volume? 14:39:18 I forget, were there any other flat-volume blocker'y type issues besides "apps surprising users with max volume" ? or is that the only/primary one? 14:39:48 hadess: only the second option makes sense, because the first would bring the issue back - the app would bump the class volume to 100% 14:40:11 rdieter: it's apps restoring their volume on startup, pushing the volume system volume up 14:40:35 hadess: whatever you want to call it, sure. let's call it blue 14:40:45 :-) 14:41:09 it's broken apps, really 14:41:37 my point is, if that issue is addressed, then are we happy to re-enable flat-volumes? 14:42:39 rdieter: what issue? the broken apps fixed? we're not in control for some of them 14:43:03 hadess: some apps will never be fixed, like web browsers 14:43:06 and that's not even 'broken' in all cases 14:43:41 rdieter: I don't know a way to address the issue. We already have warnings at https://freedesktop.org/software/pulseaudio/doxygen/volume.html and https://freedesktop.org/software/pulseaudio/doxygen/introspect.html , but software authors who use abstraction layers such as gstreamer won't read our docs 14:43:46 it needs to be blocked in pulseaudio somehow and only non-flat volumes can do that right now 14:44:16 It's my understanding, workstation WG is more-or-less considering this the primary blocker for enabling flat-volumes. Please correct me if I'm wrong. ?? 14:44:29 rdieter: I don't recall another blockery issue like "hurt your eardrums/scare the bejeezus out of you" 14:44:37 rdieter: they're already enabled 14:45:05 hadess: I think rdieter means, reverse the disabling of them in shipped config 14:45:10 which we just did recently 14:45:12 right 14:45:17 hadess: they were disabled recently, the talk is about reenabling when the issue is fixed 14:45:34 It sounds to me like that won't be, for example, within the next release 14:45:36 hadess: Also websites changing the system volume to 1 via JavaScript, you must have experienced that on YouTube. To my understanding, WebKit is not broken...? 14:45:57 * mclasen___ has never experienced that 14:46:06 mcatanzaro, correct 14:46:23 mclasen___ noted it would be a little unruly to flip-flop our volume control approach within six months. But I'm not getting the sense that's likely. 14:46:23 For some reason it happens to me with my new headphones, but never with my old headphones, I dunno why 14:46:28 mclasen___: get a demo: https://jsfiddle.net/bteam/FbkGD/ (try to reduce volume) 14:47:01 Oh, patrakov got a CVE for this, I forgot about that. :p 14:48:11 I still don't understand how that is anything other than a browser bug, but lets not go down that rabbit hole 14:48:36 ok, so given: 1. we (WG) generally consider "hurt-your-eardrums" to be a blocker issue, and 2. pulseaudio (or any other level of software stack) isn't going to address this in the foreseeable future, then I think the decision to disable flat volumes was the right one 14:48:52 mclasen___, yes in the borwser you cannot change the volume but the system control works 14:49:01 stickster: about flip-flopping, I don't see it as an issue, because it will likely be turned to class based volume control (if that is implemented) which is different both from flat and non-flat 14:49:22 mclasen___: I don't understand it either, that's why patrakov and wtay are here. :) 14:50:07 mclasen___, the browser does not really have any other option that to set the volume to 100% when the API is called to do that 14:50:12 rdieter: It seems that way to me, too. And that if upstream introduces a new volume control model (such as class-based), we'd very likely just take that upstream configuration as our new one, and look at bug reports, rather than second guess the next model 14:50:28 mclasen___: it's "the same bug in two browsers" (firefox and webkit-based) 14:50:35 stickster: +1 14:50:43 sounds like we're done then ? 14:51:29 * mcatanzaro senses we have consensus? :) 14:51:45 disabled it remains.. 14:51:52 mclasen___: Unless someone wants to propose an additional change -- it sounds like there's still discussion for upstream to have but I didn't hear anyone screaming at us for the decision, which is good :-) 14:52:11 stickster: we didn't really tell anybody 14:52:22 which is maybe a good point: put this change in the release notes ? 14:52:39 mclasen___: I forwarded the invitation to David Henningsson, and he is not here 14:52:45 mclasen___: aside from ML, bug, and this meeting, no -- but yes, release notes absolutely 14:53:02 #action stickster add disabled flat volume note to release notes 14:53:09 I think the only pulseaudio developer that likes flat volumes in theory besides me is Arun 14:53:59 wtay, in theory, i guess the original implementer also likes them :) 14:54:40 #agreed rough consensus: stay with disabled flat volumes, and stay aware of upstream changes in volume model for future releases 14:54:40 it could be 14:55:04 Thanks to all the PA and upstream guys for contributing to the discussion here. 14:55:11 do we have time for another topic ? 14:55:11 #topic Open floor (any other business) 14:55:17 go for it mclasen___ ! 14:55:23 atomic workstation probably takes more than 5 minutes 14:55:31 * stickster has to close meeting abruptly at 11am, I have a call then 14:55:32 not sure it makes much sense to open that 14:55:39 Let's save it for next meeting 14:55:47 if we have any one liner, lets rather do that 14:56:09 #action stickster Make sure rpm-ostree/atomic workstation headlines at next meeting 14:56:17 I will try to get atomic workstation prepared for the next meeting, write a Change page draft, etc 14:56:42 alexlarsson, amigadave: sorry I made you come to a flat volume discussion :-/ 14:57:03 yay! :) 14:57:18 heh 14:57:26 alexlarsson: But we are around on #fedora-workstation all day 14:57:37 anything else before we close? 30 sec to gavel drop! :-) 14:57:47 well, at least i missed my "learn about compass" talk 14:57:49 Thanks for coming wtay and patrakov, I guess we'll be seeing alexlarsson and amigadave back next week :) 14:57:52 something good came out of it! 14:57:57 :) 14:57:58 *in two weeks 14:58:11 march 30 14:58:21 OK, thanks all -- see you on the tubez 14:58:25 #endmeeting
