10:17:28 <Guest25> hello
10:18:12 <Guest25> will this work https://forum.wownero.com/t/junkie-jeff-4th-july-hard-fork-information/554
10:18:24 <Guest25> very interesting as concept
10:19:08 <Guest25> i dont know if will succeed
12:06:18 <maripol> hi
12:06:35 <maripol> qr scanner dont work on windows & linux
12:06:53 <maripol> on linux when u click on qrcode image u'll c a blank screen
12:07:10 <maripol> on windows camera open but cant read code 
12:07:26 <maripol> open camera and is not doing anything else
12:08:08 <maripol> i put qr image  from all ungle so is is code problem 
12:16:50 <malinero> never tried on a laptop, but fwiw tested it recently on android and it worked just fine. 
12:19:48 <malinero> maripol: might be a deployment issue, like a missing Qt pluggin
12:20:36 <malinero> more precisely the Qt multimedia pluggin
12:25:21 <maripol> qt multimedia is on cmake file so is other issue
12:25:46 <maripol> on android works but most uses windows and few linux
12:25:55 <maripol> 0.01 uses android
12:26:53 <malinero> i don't really understand why someone would want to scan a QrCode on a laptop 
12:35:15 <maripol> is easier from copying all ..... monero address
12:35:34 <maripol> there are tablets that runs windows
12:35:37 <maripol> or linux
12:35:46 <maripol> qrcode is must!
12:36:48 <malinero> "tablets that runs windows or linux" didn't know they exists, fair enough
22:08:42 <maripol> hi
22:08:52 <maripol> qr scanner dont work anywhere
22:08:58 <maripol> windows,linux android!
22:09:19 <maripol> before was working on android but now even there no!
22:12:13 <tobtoht> maripol: the QR Scanner isn't supported on windows and linux
22:13:25 <tobtoht> Not sure what build you're running on Android, but you need to make sure it was compiled with -DWITH_SCANNER
22:23:21 <maripol> is compiled  -DWITH_SCANNER on all versions
22:26:31 <maripol> option(WITH_SCANNER "Enable webcam QR scanner" ON)
22:26:34 <tobtoht> For Linux to work you need to compile Qt with -gstreamer, for Windows to work you need to include "vfw.h" in main.cpp. Not sure about Android.
22:27:09 <tobtoht> "compile Qt with -gstreamer" -> And have gstreamer-plugins-bad and gstreamer-plugins-good installed on your system.
22:28:51 <maripol> we are talking about static version.why u'll need  gstreamer-plugins-bad and gstreamer-plugins-good installed
22:29:14 <tobtoht> Good luck trying to get GStreamer to static link.
22:30:13 <maripol> oh
22:30:35 <maripol> gstreamer is module outside qt?
22:31:06 <tobtoht> GStreamer is the multimedia backend for Linux for QtMultimedia.
22:31:21 <tobtoht> Gstreamer itself loads plugins at runtime.
22:31:51 <tobtoht> Camerabin, which is required by Qt to load the camera, has a couple dozen other plugin dependencies.
22:32:17 <tobtoht> There is a way to compile and include plugins statically
22:32:47 <maripol> which
22:32:57 <tobtoht> But you'd have to figure out exactly which dependencies camerabin needs (which is not trivial, there is no way to get a dependency graph afaik) otherwise you bloat the binary with 50MB of useless plugins
22:33:45 <tobtoht> Moreover
22:34:02 <tobtoht> In Qt6.2 the entire QtMultimedia is revamped
22:34:16 <tobtoht> and camera access no longer depends on camerabin, but some other plugin
22:34:41 <tobtoht> so you'd have to do it all over again
22:34:56 <maripol> we are talking about qt 5.15.2
22:35:02 <maripol> why qt6
22:35:07 <tobtoht> Yes, I know
22:35:21 <tobtoht> I'm saying that, everything changes in Qt 6.2
22:35:47 <maripol> i'm confused from what u said
22:35:54 <maripol> what to do know
22:36:00 <maripol> what to do now
22:36:11 <tobtoht> Depends on what you want to achieve
22:36:20 <maripol> qrcode scanner to work
22:36:24 <maripol> is very important
22:36:29 <tobtoht> On linux?
22:36:33 <maripol> everywhere
22:36:43 <maripol> before was working on android now not
22:36:53 <maripol> on windows was working now not
22:37:25 <tobtoht> Can't help you with Android, haven't developed on that OS.
22:37:30 <tobtoht> Windows should be easy
22:37:55 <tobtoht> one sec
22:38:41 <tobtoht> I'm pretty sure this is all you need: https://paste.debian.net/plainh/c7ba109f
22:39:15 <tobtoht> For macOS you're going to have to rewrite the scanner logic
22:39:18 <maripol> on main.cpp
22:39:26 <tobtoht> because its multimedia backend doesn't support QVideoProbe
22:39:41 <tobtoht> so you'll have to use QCameraImageCapture instead
22:39:58 <tobtoht> "on main.cpp" -> yes
22:40:21 <maripol> ok on linux?
22:40:42 <tobtoht> On Linux the only way is to either
22:41:00 <tobtoht> spend two weeks of your life trying to get GStreamer and all its dependencies and plugins to static link
22:41:11 <tobtoht> or ship the application as an AppImage
22:41:59 <maripol> "ship the application as an AppImage"  what will be the benefit
22:42:08 <selsta> QR scanner worked already
22:42:08 <tobtoht> If you go for the latter you're still going to have to manually include a plugin bundle and trick GStreamer to load plugins from the AppImage instead of the local filesystem
22:42:11 <selsta> on Mac
22:42:28 <tobtoht> Oh interesting
22:42:40 <selsta> will check if it got broken recently but not aware of it
22:42:48 <tobtoht> It didn't work on my machine
22:43:04 <maripol> is not working anywhere anymore selsta
22:43:10 <maripol> i confirm
22:43:20 <tobtoht> Any logs?
22:43:48 <selsta> I'm compiling currently, can test once I compiled
22:44:44 <maripol> on linux is blank screen
22:44:50 <maripol> on android the same
22:45:00 <selsta> this should also fix it on windows https://github.com/monero-project/monero-gui/pull/3464
22:45:09 <maripol> on windows camera open but nothing happens
22:45:26 <selsta> but I never tested it on windows
22:47:56 <maripol> selsta that fix is on cmake file
22:58:48 <selsta> Qr scanner worked without issues on mac
22:59:19 <maripol> windows,linux,android ?
22:59:22 <selsta> mac
22:59:33 <tobtoht> What macOS version?
22:59:40 <maripol> the only that i dont have mac
22:59:42 <selsta> 11.4
22:59:47 <tobtoht> I guess Qt docs are wrong then
23:00:07 <selsta> I'm quite sure that is also works on Android and Windows, only static Linux was the issue
23:00:47 <maripol> can u try it now or not possilble?
23:01:05 <selsta> not really, I only have Mac and iOS phone
23:01:31 <maripol> make a executable for us
23:01:36 <selsta> tobtoht: what exactly failed for you on mac?
23:01:37 <maripol> i have android phone
23:01:43 <maripol> and linux
23:08:23 <tobtoht> selsta: Well, to be exact QVideoProbe would not deliver valid QVideoFrames. 
23:08:34 <tobtoht> I'm on Catalina though (10.15)
23:12:37 <tobtoht> also it appears I'm wrong on AV Foundation not supporting QVideoProbe. It's only missing for recording and media playback, not camera.
23:12:40 <tobtoht> https://wiki.qt.io/Qt_5.13_Multimedia_Backends
23:13:03 <tobtoht> so it must be my machine / this version of macOS that's having issues
23:13:31 <maripol> anyway is not working on windows,linux,android
23:13:48 <maripol> selsta can u make exe for linux or android to test
23:13:59 <tobtoht> it not working on linux is expected
23:14:10 <tobtoht> and it's not going to work without a ton of effort
23:21:05 <maripol> if i'm so mad to try use qt6 instead of qt5 will be any benefit about qrcode scanner or no?
23:21:58 <tobtoht> GUI won't compile on Qt6 currently
23:22:21 <maripol> why?
23:23:01 <tobtoht> Qt6 has a few breaking API changes
23:23:29 <tobtoht> so those need to be resolved in the code first
23:24:39 <maripol> no escape
23:24:58 <maripol> qrscanner is very important
23:25:08 <maripol> selsta any suggestion?
23:25:41 <selsta> currently no, but malinero said they got it to work on android
23:27:31 <maripol> how?
23:27:37 <maripol> whereis he
23:29:44 <tobtoht> "Qt6 has a few breaking API changes" -> And it's not trivial either: QVideoProbe (which provides video frames to the qr scanner) got removed in Qt 6, so a rewrite of the scanning logic will be necessary.
23:31:43 <tobtoht> Also, Qt6.2 which is the first Qt release to include QtMultimedia, which the Qr scanner needs, is still in alpha and a nightmare to build as Guest6033 can attest to.
23:31:54 <maripol> oh
23:32:34 <malinero> maripol: did nothing special for the camera, just followed the standard android build. try testing with an apk from CI pipeline
23:32:56 <maripol> link for apk?
23:34:36 <malinero> https://github.com/monero-project/monero-gui/suites/3079514649/artifacts/70281507
23:34:57 <tobtoht> ^ need to be logged in to github to view, probably
23:35:24 <maripol> yep
23:35:35 <maripol> i need to create account
