ZBar is an open source software suite for reading bar codes from various sources, including webcams. As its development stopped in 2012, I took the task of keeping it updated with the V4L2 API. This is the main repository for it. There's a clone at at LinuxTV.org, and another one at gitlab.

Might be possible to use https://github.com/dmtx/libdmtx to add data matrix support?
Hi,
I really will appreciate your help. Thanks in advance for the great work done here:
I'm trying to build for windows following all instructions but adding imagemagick since I need to build zbarimg ... for Windows.
Then the instructions I am following from a brand new Ubuntu 18.04 are:
sudo apt-get install -y \
autoconf automake autotools-dev libdbus-1-dev \
pkg-config binutils-mingw-w64-i686 gcc-mingw-w64 \
mingw-w64-i686-dev mingw-w64-common win-iconv-mingw-w64-dev \
xmlto imagemagick libmagickwand-dev gettext libtool
Then, build Zbar with:
Then, build Zbar with:
export PKG_CONFIG_PATH=/usr/x86_64-w64-mingw32/lib/pkgconfig
autoreconf -vfi
CC=i686-w64-mingw32-gcc ./configure --host=i686-w64-mingw32 \
--prefix=/usr/local/win32 --with-directshow \
--without-gtk --without-python --without-qt --without-java \
--enable-pthread
make
But after compiling everything else to that point I am getting the following error:
CCLD zbarimg/zbarimg.exe
/usr/bin/i686-w64-mingw32-ld: cannot find -lMagickWand-6.Q16
I will appreciate so much your help. We have a great need to build this one.
Thanks in advance again.
Hello!
I am attempting to make a PDF417 barcode reader for the web using Web Assembly (there's a few out there but the only reliable one is licenced). The idea is simple, just build a binary file with C code that can be called via JavaScript.
I followed this guide which got me almost there! I had to add --enable-codes=pdf417 as a parameter to configure to enable PDF417 symbols and disable all the others I'm not interested in.
The code actually works amazingly well for any other type of symbol (see demo) but if I compile ZBar to accept PDF417, it detects it but throws a warning:
WARNING: zbar/decoder/pdf417.c:73: pdf417_decode8: Assertion "clst >= 0 && clst < 9" failed.
dir=0 sig=5a44 k=9 buf[0000]=
WARNING: zbar/decoder/pdf417.c:89: pdf417_decode8: Assertion "g[0] >= 0 && g[1] >= 0 && g[2] >= 0" failed.
dir=1 sig=ca03 k=6 g0=ffffffff g1=e71 g2=585 buf[0000]=
And of course, no decoding is done. Those assertions are on lines 71 and 86 of ZBar.
You can see all the code I'm using in the guide I mentioned earlier (the only difference is that I enabled PDF417 before compiling)
For any other type of barcode it works amazingly! Is PDF417 not fully implemented? Is there anything I can do to make it work?
Here's a few patches that might be useful.
0001-Include-windows.h-for-vfw.txt
0002-Specify-correct-path-to-barcode.png.txt
0003-Check-for-clock_gettime-on-pthread-library-as-well.txt
0004-Disable-zbarcam-gtk-on-Windows.txt
0005-Use-no-undefined-for-libzbargtk.txt
0006-Make-zbargtk-build-on-Windows.txt
0007-Make-use-of-glib-thread-names.txt
0008-Correctly-generate-version.xml-and-reldate.xml.txt
Currently, ZBar is too sensible to image rotation, as can be shown with this small script:
$ mkdir rotated; cd examples
$ for i in code-128.png; do for j in $(seq 1 359); do n=${i/.png/-$j.png}; convert -rotate $j $i ../rotated/$n;done; done
$ for i in ../rotated/*.png; do if [ "$(zbarimg $i 2>/dev/null|grep CODE-128:https://github.com/mchehab/zbar)" == '' ]; then echo $i; fi; done|wc -l
316
Perhaps it should pass the image to an algorithm that would try to improve the image before running the decoders.
When are new releases made?
I would like to use the new binary qr scanning feature, but this is not in the latest release. For now, I am using the the latest commit, but sake of configuration management it would be nice to have a new release at some point.
Thanks!
Hello there,
I'm fairly new to QT5 and I cannot figure why the QZBar class does not want to work. I can successfully scan barcodes with the zbarcam cli tool but cannot use it inside my app.
I do not have X server installed and use the framebuffer to display my app fullscreen. The app works well without the QZBar code.
I'm using v4l2loopback to convert the stream from my camera to a proper format (using gstreamer). I cannot figure out why it cannot find any output format. Can you help me? Thank you!

Even when configured to use Qt5, the created and installed pkgconfig file always references qt4 - the Qt5 components are called Qt5Core/Qt5Gui.
Is it possible that from the current version also the /bin directory with e.g. zbarimg.exe is also checked in?
I think not everybody has the possibility to get the build running by himself/herself, so makign the binaries available would possibly be useful

Decoding QR codes containing binary data with zbar 0.23 produces incorrect output.
I can reliably recover base64-encoded binary data encoded as alphanumeric and binary QR codes. However, binary data encoded directly in a binary QR code isn't decoded correctly by zbar.
Here's a script that reproduces the issue:
dd if=/dev/urandom bs=1024 count=1 > test.bin
base64 > test.b64 < test.bin
qrencode -8 -o test.bin.8.png < test.bin
qrencode -8 -o test.b64.8.png < test.b64
qrencode -c -o test.b64.c.png < test.b64

I removed the qrcode in enable_codes string at line 102 in configure.ac then built the program. Still detects QR code. Also, when i try to add some printf statements in function zbar_process_image in processor.c, it doesn't recognize the changes, and the new added codes don't work.
These two issues appear to happen at the same instance, so i think they are related.

Hi,
maybe (probably) is an obvious question: Android port has a google play services dependencies, or not?
I ask this because, in my project, I use google vision.
Google Vision depends on google play service, which needs to be always updated, otherwise user, before scanning, has to wait until updating from google play store is completed.
It is a annoying issue
Thank you!
Lewix
I would like to invite @bzed to get involved in our Debian packaging, which is based on the official one. We have continuous integration builds for Debian sid.
We should consider whether current version of ZBar could be included in Debian buster. Looking at buster freeze policy, I think it is feasible. We can discuss details if you are interested.
ZBar does not handle any inclination (exception: SQ code), it only processes space/bar pairs horizontally and vertically. In QR code, it detects the corner finders like 1D barcodes.

This issue is originally reported to https://bugs.debian.org/719013 .
I just tested this with zbar version 0.22, and sure enough, the problem still exist:
$ yes | dd bs=1 count=3000 | qrencode -S -v 32 -o /tmp/foo.png
$ zbarimg /tmp/foo-0*
scanned 0 barcode symbols from 2 images in 0.16 seconds
WARNING: barcode data was not detected in some image(s)
Things to check:
- is the barcode type supported? Currently supported symbologies are:
. EAN/UPC (EAN-13, EAN-8, EAN-2, EAN-5, UPC-A, UPC-E, ISBN-10, ISBN-13)
. DataBar, DataBar Expanded
. Code 128
. Code 93
. Code 39
. Codabar
. Interleaved 2 of 5
. QR code
. SQ code
- is the barcode large enough in the image?
- is the barcode mostly in focus?
- is there sufficient contrast/illumination?
- If the symbol is split in several barcodes, are they combined in one image?
- Did you enable the barcode type?
some EAN/UPC codes are disabled by default. To enable all, use:
$ zbarimg -S*.enable <files>
Please also notice that some variants take precedence over others.
Due to that, if you want, for example, ISBN-10, you should do:
$ zbarimg -Sisbn10.enable <files>
$
I expected zbar to handle QR codes generated by qrencode.
The file examples/sha1sum is missing in the distribution archive (this was the case in the upstream 0.10 archive already). This inhibits running the tests (test/test_examples.sh fails on all test-cases).
I recently tried to decode a QR code of the chip tan stuff my bank does (out of curiosity what's encoded in it). Scanning such a QR code makes zbar crash. See the attached demo QR code:
The content seems to be some binary data, using https://zxing.org/w/decode.jspx , I get:
DK
X@Ã\2'NrND;�]uywgp~[rì
Perhaps, zbar expects the QR code content not to be bytes? Anyway, would be cool if it wouldn't crash ;-)
Bug is in ZBarReaderView.m - Line 585
I'm getting a few of these in Firebase Crashlytics from live users.
for(ZBarSymbol *s in syms) if(!sym || s.type == ZBAR_QRCODE || s.quality > sym.quality) sym = s;
Somehow syms must be getting updated elsewhere in the code while this loop takes place. Maybe copy syms before enumerating it? Just a guess, because I'm not sure how the code flows here.

Hi, I am running on a Macbook Air and have been passing my webcam via VirtualBox to a VM, a headless Arch Linux machine running
zbarcam --nodisplay -Sdisable -Sqrcode.enable
It will usually run fine for 10-15 minutes, and then will stop scanning and then will make an endless loop of printing the following. It will also cease to scan correctly:
"Not a JPEG file: starts with 0xff 0xd9"
Running zbar not in headless mode doesnt seem to produce this problem.
But, this required me to install a dummy X driver and a lot of other configuration I would rather not have to do. (launch X just for zbar, then appropriately kill it)
Let me know if you need any more information about my system.
I have created some large QR codes with qrencode -v 40 (~1600 bytes base64 text per QR code). The resulting files can be decoded with zbarimg without any issues, as expected:
martin@dogmeat ~ % zbarimg -q --raw admin-pins.txt.xz.gf.100.gz.png | head -c 10; echo
H4sICNsLeV
martin@dogmeat ~ % zbarimg -q --raw admin-pins.txt.xz.gf.103.gz.png | head -c 10; echo
H4sICNsLeV
martin@dogmeat ~ % zbarimg -q --raw admin-pins.txt.xz.gf.162.gz.png | head -c 10; echo
H4sICNsLeV
Then I printed these PNG files and then scanned them with our office printer into a PDF file with the scanner set to 800 dpi. I then used GIMP to convert the PDF pages to PNG. Decoding these PNG files with zbarimg seems to be very hit-and-miss - on my first attempt, zbarimg would only read 1/3 files, on the next attempt 0/3, and now 2/3 files:
martin@dogmeat ~/Downloads % zbarimg -q --raw 1.png | head -c 10; echo
H4sICNsLeV
martin@dogmeat ~/Downloads % zbarimg -q --raw 2.png | head -c 10; echo
H4sICNsLeV
martin@dogmeat ~/Downloads % zbarimg -q --raw 3.png | head -c 10; echo
I made another attempt with GIMP set to 200px/in, no anti-aliasing, and now it's again 0/3:
martin@dogmeat ~/Downloads % zbarimg -q --raw a1.png
martin@dogmeat ~/Downloads % zbarimg -q --raw a2.png
martin@dogmeat ~/Downloads % zbarimg -q --raw a3.png
martin@dogmeat ~/Downloads %
Possibly related to #21? I've tried to fiddle with GIMP settings now a lot, also tried my hand at manually rotating the images, but I haven't found a reliable way to decode all three images :(
These are the original files as generated by qrencode, which work fine:
admin-pins.txt.xz.gf.100.gz.png
admin-pins.txt.xz.gf.103.gz.png
admin-pins.txt.xz.gf.162.gz.png
This is the scanned PDF: DOC190911-20190911171020.pdf
This is the attempt where 2/3 work:
This is the attempt where 0/3 work:
It might be a good idea to enable coverity scanning on this codebase which is free for open source projects. See here for details on signing up. I suspect it would find a number of issues on a large older parser heavy c codebase like this.

However, when i try to import zbar, it throws the above error. Have tried on 4 different machines, both python 2 and 3, I still couldn't get past this. Currently i have to use subprocess, but i don't think it is the ideal way to do.

qrencode has

But

cannot read them.
I am trying to use zbarcam in --nodisplay mode with a USB camera.
The camera resolution is 1600x1200, zbarcam uses 100% CPU.
Using --prescale=800x600 or -Sx-density=8 -Sy-density=8 the CPU usage goes down to around 70% which is still too much.
The laptop is a Lenovo Edge E545, 4 core AMD A10-5750M APU, 2.5GHz.
Is it planned to make zbar to use GPU acceleration for barcode decoding through Mesa?

v0.23 works fine though 👍
Python 2 will stop maintenance by 2020. I guess it's reasonable to open an issue to migrate away from python2 (as well as gtk2).
Trying to run configure on the latest raspbian image, these issues occurred:
needed to 'apt-get install gettext' to get past an issue with AM_ICONV(). It then could tell me it wasn't using gettext
needed to 'apt-get install libgtk2.0-dev' Tried libgtk-3-dev but that failed
cannot install the java examples because javah is missing under jdk11. These days the header files are produced from the .java files using javac -h
See this article for the gory details: https://stackoverflow.com/questions/48816188/kotlin-replacement-for-javah
It seems the only solution is to use java 8 :-/
While I am here, two questions:
what is an "SQ Code" as opposed to a QR Code, and how would I generate one?
and does anyone know what the codes in the boston dynamics warehouse video are?

Hi there,
ZBarHelpController.h/.m use UIWebview, and this API is on Apple's deprecation list:
https://developer.apple.com/documentation/uikit/uiwebview
When uploading the app to appstoreconnect you get a warning that future submissions containing these API references will be refused automatically.
Apple's direction is to replace use of UIWebView with WKWebView.
I'm working on fixing this locally. But, just in case I missed something, I'm raising this issue ticket for awareness and fair warning in case there's a clamour of 'It's fixed already - look more closely!'
Thank you,
Ben.

This broke cross compilation from Linux to Windows using MinGW.
See these for reference:
libcoap seems to have replaced AC_FUNC_MALLOC / AC_FUNC_REALLOC with AC_CHECK_FUNCS which works properly for cross compilation.
Hello,
I'm using zbar 0.20 from the command line (invoked from a PHP script, if that matters), to decode a png image that contains a single Code-93 barcode (extracted from a PDF).
Every hundred barcodes, I get one that is not being decoded, a failing sample is attached.
zbar does not crash nor segfaults, it simply answers me:
scanned 0 barcode symbols from 1 images in 0.02 seconds
I have tried with v0.23, and I get the same result.
Any ideas on how to proceed from here?
I am having some difficulty installing on my system, as discussed in #64 . This is probably due to my n00bness on the topic of locally compiling / installing things.
This makes me think about a couple of questions:
https://packages.debian.org/jessie/zbar-tools
https://manpages.ubuntu.com/manpages/bionic/man1/zbarimg.1.html
it does not seem so (the old SourceForge project is still what is linked I think).
@matheusmoreira that may be of interest to you too, as you know I am especially interested in the features of your binary branch :)
This is Debian #719013. Besides doing a graceful exit, I do not know whether QR codes split in different images should be supported. If the structured QR codes are in the same image, data is decoded successfully.
could you remove that from the tarball releases? it'll make it easier to maintain for debian maintainers. (or just put it in a debian branch if you want to keep it)
This is caused by commit d09afa6
First I had a problem where it told me ZBAR_SQCODE is undefined, which I traced back to it using my system zbar.h. After I uninstalled my system zbar it complained about not finding zbar.h.

Hello,
Currently on the development version of Fedora, we've updated the python interpreter to the latest version (3.9) and rebuilt all the dependent packages. zbar failed to build from source due to tp_print being removed from PyTypeObject (used in the enumitem_print function in python/enum.c)

Any possibility you can fix these warnings and bring the iPhone version completely up-to-date?
It's so awesome that you have taken the time to fix the UIWebView deprecation already. I really appreciate it!

This is useful for scripting, where you may not want to receive duplicate data.
While working for the Debian package, I noticed the following typo:
Line 134 in dc9f5d1
shoud should be should.
This is an issue opened after some discussion happening on stackoverflow:
I have some binary data that I want to encode in a qr-code and then be able to decode. I want to use binary data purely for the efficiency of the encoding (i.e., I want to have a qr-code of minimum size given the data to transmit).
It looks like qrencode is able to correctly encode, but that zbarimg does something weird at decoding.
Do you agree with the conclusions that are reached on the stackoverflow thread?
How could binary data decryption take place? Is there already a way to do that? If not could this be added / how / who could add / test it (note: I can try to help to my best).
Attached is a image with a QR code where zbar failed to see it, while smart phone readers are able to read it. Is there some way to get zbar to recognize it too?
Hello,
I'm having problems when I hide and show, respectively, a ZBarGtk widget using gtk_widget_hide and gtk_widget_show. Initially the ZBarGtk widget is initialized and visible and displays the video stream from the webcam correctly. When I now hide the widget and show it again, no video stream is visible (note: the widget containing the ZBarGtk widget gets resized correctly upon show and hide, only the video stream is missing); when I drag another window over the ZBarGtk widget it gets refreshed and the video stream is visible again.
I can reproduce this with the zbarcam-gtk application easily by adding gtk_widget_hide and gtk_widget_show calls to the status_button_toggled callback function.
Has anyone got a clue what can be done here?
Thanks and best regards,
Christian
After PR #2, when SQ code is built, and a non-SQ image is used, it may loop forever.
So, calling it with
zbarimg examples/*.png
will loop forever.
Can anyone tell me how to start the application? I have it installed on Debian 10 but there is no menu item.
Thanks.
Hello,
what am I missing? When I cd into the zbar folder to run
./configure
I get:
./configure
-bash: ./configure: No such file or directory
Am I blind? or isn´t there any configure file in this repo?
