hello

Do anyone knows how to ask permission for camera on linux

android has a file named androidmanifest and you insert there "<uses-permission android:name="android.permission.CAMERA" />"

and camera work

something like this on linux please

For?

for enabling camera

if camera is not enabled qt dont work

qr dont work

Qr grabs image from screen iirc

yes but sometimes you need camera

your qr is printed

monero gui has to be built with camera support , my OS has never asked me for permission, only a web browser

Probably handy in merchant mode, or restoring URIs.

Eudaimon wanted qr code cam (- is that you eud?)

no

"WITH_SCANNER "Enable webcam QR scanner" ON"

gui is build with qr scanner enabled but camera need permission

on android when app opens ask u about camera permission and thats it

Android is a permissioned system.

on linux gui dont ask so camera has no permission and wont work

Flatpak is as well

Try using Flatpak, and using `flatseal` to "give permission"

when i click "scan qr code"  icon camera gives me a black hole!

and was doing the same on android before adding ""android.permission.CAMERA""   on androidmanifest

what OS are you using

debian

(Unable to test cameras)

i was missing.... uhm

during build i noticed some errors in the log

i noticed this: defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.camera"

during build, and i needed to install some dependency

linux?

ubuntu yes moment

i installed libqt5multimedia5-plugins on ubuntu , then i re-built monero gui

maybe this is your issue

sudo apt-get install libqt5multimedia5-plugins

this i must install where i compile or where i run ?

try to sudo apt-get install libqt5multimedia5-plugins

does it download/install anything? then re-compile monero gui

its for your operating system

i'm compiling with dockerfile

hm

add it to the docker file?

ok

where the docker install dependencies add it hm

ok

libqt5gui5-gles : Conflicts: libqt5gui5 but 5.5.1+dfsg-16ubuntu7.7 is to be installed

package conflicts

I wish you the best of luck

i had before this errors here paste.debian.net/1275640  that's why i added but still no luck

can you not just build without docker , debian is supported for build

ok

The GUI won't have scanner support when you link against static Qt on Linux (which is what happens if you use the Dockerfile). This is due to how Qt's plugin system works. You would need a static build of Qt's multimedia backend (GStreamer) for this to work or you can compile a non-static build from source with -DWITH_SCANNER=ON. It has nothing to do with permissions.

if we manage to compile this github.com/GStreamer/gstreamer  on docker is done?

Build a static version of gstreamer

or

Compile a non static build of gui, and use the cmake flag DWITH_SCANNER=ON

i'll try and come later to tell

Thnx
