Hi, Just to let you know, I added today a repository at linuxtv.org with a fork of the ZBar bar code reader. The Zbar tool is an interesting V4L2 application, as it reads code bars from several different codes from a webcam (or a scanned file). The original page for this project is at http://zbar.sourceforge.net/ Unfortunately, it doesn't have maintenance there, since 2012. This was its last commit upstream: changeset: 362:38e78368283d tag: tip user: spadix@xxxxxxxxxxxxxxxxxxxxx date: Sun Oct 14 23:02:08 2012 -0700 summary: Added tag iPhoneSDK-1.3.1 for changeset 5eb3c8786845 At least on Fedora, upstream version doesn't even compile without fixing configure.ac to work with modern automake tools. As Douglas and I are maintaining this package under Fedora, and I had to write some other patches on Fedora, in order to migrate it to Qt5, I'm opting to keep a fork of its patched version at linuxtv.org. The version there is basically the original development tree, converted from Mercurial to git. For the few patches at the Fedora packaging repository, I added a commit, in order to preserve credits for the authors of the changes there. Please notice that I don't have currently any plans to do any development on it, doing mainly bug fixes as required to keep it building and working. So, if anyone is interested on keeping maintaining it, please ping me. Feel free to also send patches for it to linux-media ML. Thanks, Mauro [1] I got the zbar patch credits by running: $ git log zbar*.patch Please notice that this doesn't cover other patches that were there at the repository, but got removed.
