Most >system will prefer this over the ISO 9660 superblock and tree. Specifically focused on 3rd party TV related bluray players (eg. Sony, LG, Samsung, ...) I noticed the "-udf" option for mkisofs (and applicable for growisofs) creating a bridged or hybrid type filesystem. (mkisofs notes, wastes space ... when using "-udf" option, look like minimal space though.) So this should create a readable BD-R media for TV bluray players, but not necessarily playable due to a missing directory structure/file? My best guess is recent TV bluray players should likely have no problem reading any UDF filesystem disc, although I would be more satisified to see most recent players able to read an ISO9660 disc. I would expect recent TV players should read both filesystems, as people do tend to backup photos, video and audio to DVDR/BDR media; and likely not going to waste time with editing structure files. They just need some form of shareable media, but think the usb flash media has locked-up the market on this for now except for being reliable/stable media. >> Suggestions feedback for creating/backing-up photos/video to BDR with TV >> Bluray player hardware support? > >Wikipedia says you need UDF 2.50 or higher and you have to provide a >particular directory structure: > https://en.wikipedia.org/wiki/Blu-ray#Data_format_standards >I am not aware of a program which would produce this on Linux or BSD. >Some people use Wine and old versions of MS-Windows Blu-ray authoring >programs. > >Try (by a BD-RE medium to avoid waste) whether your target player can >access files in the UDF version of growisofs/mkisofs or in ISO 9660. Yup, after two days, finally found my boxed-up DVD+RW & BD-RE media. Making this a little more difficult, the Linux pktcdvd driver is slated as deprecated/removal, albeit oddly since 2016 and still is within the kernel. Hopefully I don't have to waste money on a TV bluray player for checking on this filesystem readability issue. Another option for testing is if there were TV bluray player firmware booting via emulation software. -- Roger http://rogerx.sdf.org/
