The following articles made me aware of some basic Blu-ray tools of interest: https://www.videolan.org/developers/libbluray.html https://wiki.gentoo.org/wiki/Blu-ray https://packages.gentoo.org/packages/media-video/bluray_info ======= After installation on current openSUSE Leap 15.3, this looks like: zypper se -is bluray Loading repository data... Reading installed packages... S | Name | Type | Version | Arch | Repository ---+------------------+---------+------------------+--------+---------------- i+ | libbluray-bdj | package | 1.3.0-lp153.96.1 | noarch | multimedia:libs i+ | libbluray-tools | package | 1.3.0-lp153.96.1 | x86_64 | multimedia:libs i+ | libbluray2 | package | 1.0.2-2.38 | x86_64 | Main Repository i | libbluray2-32bit | package | 1.0.2-2.38 | x86_64 | Main Repository And to list the libbluray-tools: rpm -ql libbluray-tools /usr/bin/bd_info /usr/bin/bd_list_titles /usr/bin/bd_splice A fourth tool, "bluray_info" used in the Gentoo article, I didn't packaged for Leap i.e as rpm, and I didn't succeed to compile and install it using "Linux" procedure in the tar install file. So tip here is welcome ;) http://bluray.beandog.org/bluray_info/ https://sourceforge.net/projects/bluray-info/ ======= Without going in detail on each disc content and structure, here are my preliminary test output for some earlier written BD-RE discs (Nero Linux and bdwrite). Most of them recognized by my Samsung UBD-K8500 player as Data discs. Autoplay not started for /udfs/BDMV/BDAV (as it does for DVD SD and Wide-SD), but it is possible to browse down to STREAM and play video files (m2ts, AC-3, HEVC, h264, HD and SD, but not pure dv.avi). (Browsing is not required with VLC, with Nautilus just open the top directory: Open>with VLC which starts playing a single video file.)
