Welcome to libburnia project


  • Sun Feb 07 2021 Release 1.5.4 is ready on release page. libburn offers new opportunities to influence drive speed. libisofs libisofs got a bug fixed which under medium rare circumstances spoiled zisofs production. libisofs switched to usage of libjte-2.0.0. Further it can now write and read zisofs2 format, which enables compression of files >= 4 GiB. When reading Joliet file trees the names get stripped of their version numbers by default. After loading metadata, libisofs can now tell which directory tree was loaded and whether Rock Ridge is used. xorriso and libisoburn make use of these new features. xorriso can put out the data stream of -check_media to standard output. It can restore files with many zero bytes as sparse files and it is able to extract recognized boot images into data files on hard disk. A new script xorriso-dd-target helps to put an ISO image onto an USB stick without endangering valuable hard disk content. Several rarely triggered bugs were fixed.

  • Sat Aug 01 2020 we celebrate 14 years of libburnia project.

  • Wed Jul 08 2020 We moved from GitLab to Gitea.


libburnia is a project for reading, mastering and writing optical discs. Currently it is comprised of libraries named libisofs, libburn, libisoburn, a cdrecord emulator named cdrskin, and an integrated multi-session tool named xorriso. The software runs on GNU/Linux, FreeBSD, Solaris, NetBSD, OpenBSD. It is base of the GNU xorriso package.

The wiki article about problems with concurrent burns describes two workarounds for the poor throughput which can be observed on Linux if libburn operates more than one drive at a time. This problem seems to have been fixed in Linux 5.6.
