Welcome to libburnia project


  • Tue Aug 01 2023 we celebrate 17 years of libburnia project.

  • Tue Jun 20 2023 Release 1.5.6 is ready on release page. libburn can overburn CD media, i.e. write more data than the drive announced as medium capacity. libisofs can assess many of the features which were in effect when a given ISO 9660 filesystem was created. A safety limit was introduced not to exceed the limit of Linux which is imposed on the number of SUSP CE entries which is good for about 60 KiB of AAIP data. Some rarely occuring bugs were fixed in libisofs. xorriso and libisoburn expose the new library features to the user and got some minor improvements. Many minor bugs were fixed.

  • 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.

Be aware that linking libisoburn with GPLv3+ library libreadline-6 will automatically change the license of the resulting libisoburn.so and xorriso binary to GPLv3+.
