cobang's Issues

Package it as a Snap

For an easy installation clicking in Software in Ubuntu, which is the first Linux distro for many new users now coming to Linux.

Thanks a million if this could be possible!

Mention works with barcodes too

Many thanks for this app. I think it would be a good idea if it could be mentioned that it works with 2D barcodes too (presumably it works with all codes that ZBar recognises), e.g. in the Readme, Github about text, Debian/Ubuntu package description, for ease of people finding your app when searching for "barcode".

[Question]: egg-info folder no longer installed

Do you think that could possibly be a problem?

displayed wifi passwords have max length of 20 characters

I noticed the displayed wifi passwords have a max length of 20 characters. An Italian ISP (TIM) appears to use wifi passwords of 24 characters on their routers, so it might be interesting to increase the max-length of wifi passwords.

Crash on startup

I'm running Arch Linux and I've installed CoBang through the AUR.

When I start CoBang it instantly crashes. This is what the terminal shows me;

Please clarify licensing terms

I see the package being under gpl3.0+, but apache 2.0 is mentioned here, here and here.

Do both apply? Either? Only GPL?

Not starting at all

Hello,

Using the latest version from master (96742ff), cobang doesn't start at all (debian sid fully updated from 2020/11/25):

$ LANG=C cobang
[E][000053714.272167][core.c:71 core_event_error()] core 0x3854230: proxy 0x38678e0 id:11: bound:47 seq:80 res:-16 (Device or resource busy) msg:"enum params id:3 (Spa:Enum:ParamId:EnumFormat) failed"

Segmentation fault

It seems to be related to pipewire and gstreamer...

From ppa install error

Intall from ppa on Ubuntu 20.04:

cobang: Depends: python3-single-version but will not install
Depends: python3-logbook but will not install
Depends: python3-kiss-headers but will not install

dependencies are not in the Ubuntu repositories

Create Debian packaging script

We don't need to publish CoBang right now, just make a working packaging script, changing the project structure if needed.

Create debian package script for Logbook

CoBang depends on Logbook. To be able to package CoBang as *.deb file and published to PPA, logbook must be available as *.deb on some repo first.

Issues in building and packaging

Currently, there are two issues that will make building and packaging for other distros fail:

• I cannot make meson detect and building translation files (*.po). So build script calling meson will not work.
• The setup.py doesn't install dependencies (like Babel). It is because recent breaking change of pip make it fail if being called from Debian packaging tool.

So, the current solution is:

• Use setup.py script.
• Let your build script install dependencies before running setup.py.

Flatpak broken

After latest update the flatpak is broken.
Terminal log:

[Minor]: The close button doesn't actually close the about window

As per subject.

Using openSUSE Tumbleweed

Flatpak: CoBang doesn't memorise window size

Precondition: CoBang opens with a useful window size - all active elements are accessible.

Action:1 Scan any QR-Code - the result is shown at the bottom of the window, partly invisible.

Action 2: Resize the window to make all active elements accessible again. Then close the application.

Problem: At next start of CoBang it is in the same state as in "Precondition".

Expected: The adapted window size from step "Action 2" is memorised.

Linux Mint 21.1, Cinnamon, Flatpak installation. Screen resolution 1600 x 900

does not open on Ubuntu 20.04 installed from PPA

I've installed cobang from the PPA.

It does not open. They only message I get is "Failed to register. Timed out."

Any ideas how to get it running?

Convert "Add file" button to overlay button

Add license file

Hi,
nice to see a new QR GUI app.

Could you add a license file to the project? So potential contributors and users know how they can use the or contribute to the program.

Thanks

Crash when running inside Flatpak (v0.9+)

Since v0.9, I cannot distribute CoBang as Flatpak, because CoBang crashes right after the webcam video plays. Tried downgrading GStreamer version to v1.16 but it still crashes.

GUI: Headerbar based Mockup

Hello,

after reading the reddit thread, with the message about using header bars. I thought I try to come up with an idea how the application could use them.

This is just a WIP to try out some ideas. There are several issues (colours, alignment, icons) and not all functionality is included. I also have several ideas for a phone layout, but this is mostly about reordering elements based on the width of the window.

Do you find this helpful? Is this even a direction of UI you would like go into?

There are two main sections of the application: reading qr codes and creating qr codes. The first one shows three cases: without webcam, one webcam and multiple webcams.

On the right side you see the base layout for qrcode creation. On the left you get the resulting qrcode with visual options below. On the right you select the content type of the qrcode. Based on the type selection you see different "forms" for inputting structured data, just like in qtqr.

suggestion

hi, your CoBang app is excellent. please add to the user interface an easy way to copy raw results to the system clipboard (for copy and paste). such as a "Copy" (or Copy Result") button to click. much appreciated. best regards. thanks

Mysterious crash at the first time detecting wifi info

How to reproduce (not always reproducible):

• Restart PC
• Open CoBang
• Open Android phone, chose to share a wifi info under the form of QR code
• Show the QR code in front of CoBang

What is expected:

• CoBang show the wifi info in the right sidebar.

What happened:

• CoBang crashed.

does not work on Ubuntu 20.04 (thinkpad P70)

cobang shows the 'Integrated Camera' in the selection box but the view panel stays black.
guvcview works without any problems, so must be a cobang bug.

Planned features

• Generate QR code
• Drag/drop images
• Paste image from clipboard

Consider the new version of Pillow (9.X)

Thank you for the development of this application. Currently I'm porting it to Nixpkgs (NixOS/nixpkgs#149729) and I can say it works as intended.

Unfortunately, the only reason I can't merge it yet is because Pillow has been recently updated to version 9.X. Not that I continuously use the application, but it would be something to consider for future versions, if possible.

Thank you!

0.6.2 install fails

Packaging CoBang for openSUSE linux, this is what I see after the last update:

+ /usr/bin/meson install -C noarch-suse-linux --no-rebuild
Relocate to /home/abuild/rpmbuild/BUILD/CoBang-0.6.2
running install
running build
running build_py
running compile_catalog
error: invalid command 'compile_catalog'

Reduce discrepancy of building tools

Due to the need of publishing our app to various channels, the build method are now too diverse:

• First, we use Poetry both to manage dependency and build, with the pyproject.toml file being the main script for building. However, the 2nd purpose failed, because our app cannot be distributed via PyPI (due to the inclusion of desktop-integration files like icons, *.desktop file).
• Then, we need to build Debian package. We need to generate setup.py file from pyproject.toml, because Debian doesn't support Poetry.
• Next, we need to build Faltpak package. Because of it, meson.build is added.

So, we are having 3 build scripts: pyproject.toml, setup.py, meson.build. Pretty cluttering now.

Support SVG input

Flatpak can't access gstreamer plugin

I just installed 0.10.1 from flathub, yet it can't access the camera due to these errors:

Camera not working on Pinephone

I am running CoBang on a Pinephone with Arch Linux and Phosh.
Starting CoBang from the command line (SSH) shows:
$ cobang

(main.py:12121): GStreamer-CRITICAL **: 08:43:05.970: gst_element_message_full_with_details: assertion GST_IS_ELEMENT (element) failed

(main.py:12121): GStreamer-CRITICAL **: 08:43:05.971: gst_element_message_full_with_details: assertion GST_IS_ELEMENT (element) failed

There is no video and it seems that only one of the cameras has been identified

According to the wiki

The PinePhone has two cameras, OmniVision OV5640 with 5MP (up to 2592 x 1944 pixels) as rear camera and GalaxyCore GC2145 with 2MP (up to 1600 x 1200 pixels) as front camera.

Both cameras work with Megapixel.

Drop Cheese from dependencies

We are using CameraDeviceMonitor from Cheese to catch the event when webcam device is plugged or unplugged.

But it adds a burden to Flatpak building task. We don't use the whole Cheese app, but only a part of its library. While making deb package, it is just as easy as adding "gir1.2-cheese-3.0" to dependencies list, it is not the same when building Flatpak, we have to guide flatpak-builder to build Cheese from source.

So, it is better to implement "device monitor" from plain GStreamer and drop Cheese.

Reading PDF 417 barcode

Currently, CoBang only read square QR code. It should support 2D barcode, too.

Standalone Executable?

Just for the sake of testing, making a a standalone executable(AppImage or Pyinstaller) might beneficial. Adding a PPA just for trying is a bit cumbersome. And not everybody has Flatpak setup.

Package it as a Flatpak

I really like this project and that it's a native GTK app without a dependency on X. Sadly I'm not on Ubuntu and I understand that I'd be too big of a hassle to package it for all the relevant distros out there. So could you package it as a Flatpak besides a native Ubuntu package please? That way all the people on the many distros that support Flatpak out of the box could easily find it in their software centers. That would also make it work on Silverblue :D

Not possible to scan more than one QR code

Precondition:

After start of the application it is instantly ready to decode a QR-Code - this works fine. In case of an URL it can be clicked and Web Browser opens as expected.

Camera picture still shows the "scene" (frozen picture) of the moment when CoBang decoded the presented code.

Problem 1: It seems not possible to scan another QR-Code right now.

Action:

Switch decoding from camera to file and back to camera

Problem 2: CoBang now receives new frames from the camera (life picture), but does not decode QR-code anymore.

Workaround: Close and restart CoBang

Proposal: Add a button to start a new decoding process.

Linux Mint 21.1, Cinnamon, Flatpak installation

CoBang doesn't work under Wayland

Ubuntu 22.04 with Wayland.
Gdk-Message: 13:07:48.828: Error flushing display: Protocol error

[Question] Does it work on X11?

Does this app work on X11 DE's, like KDE Plasma 5?

Or do I have to use wayland?

Can't make video work

Packaged 0.8.0 on openSUSE Tumbleweed, application start and it loads and properly decodes a file, but it doesn't show anything in the video tab.

This is what I see on startup:

What could be possibly missing?

Full disclosure: I'm using a simulated webcam via v4l2loopback. It creates /dev/video0 and according to strace, CoBang is opening it. It also works from a web browser.

Is there a mistake in pyproject.toml?

Flatpak version is outdated

Other distributions then Ubuntu are advised to install the flatpak-version of CoBang, but the version in flatpak is outdated.

Is there a reason for this ?

Can you need help with publishing it on flatpak ?

GNOME 44 runtime available

Just saw this app on my shrinking flatpak list --app-runtime=org.gnome.Platform//43 output, nothing too urgent though :)

App doesn't start, missing dependencies

Installing the software per this

gives

$ cobang 
Traceback (most recent call last):

    raise ValueError('Namespace %s not available' % namespace)
ValueError: Namespace Rsvg not available

thus making it unstartable.

Then after finding this and doing

sudo apt-get install gir1.2-rsvg-2.0 python3-cairo python-gi-cairo python3-gi

the app was startable.

It seems you're missing some dependencies in the PPA install?

Cobang on Arch

I am trying to get cobang running on Arch Linux but it is throwing the error
Traceback (most recent call last): File "/usr/lib/python3.8/site-packages/cobang/app.py", line 597, in on_new_webcam_sample img = zbar.Image(width, height, 'Y800', mapinfo.data) TypeError: expected bytes, memoryview found

Am I missing any dependencies or is this an cobang issue?

Migrate to GTK 4 + Libadwaita

Before adding QR code generation feature, before making UI more complex, let's move on the latest UI technology, so that the job of refactoring UI code less difficult.

Also, let's use Blueprint as language for UI. XML is too verbose. When using GTK 4 and Blueprint, we have to have a step to build UI files, so the current approach of running Python app in development have to be changed, we cannot run directly in-develop source file anymore. So how the new project structure should be? We can take https://gitlab.gnome.org/GabMus/swatch as reference.

Unicode characters not showed

If scanned QR code has some specials lowercase characters (like é, à, ä, etc). CoBang doesn't handle it correctly.
I'm using CoBang 0.9.6 on Manjaro.
