From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

[solved] How to backup a bunch of blu-rays? (lemmy.ml)

Seeing that DVD are slowly going end-of-live and that you can't buy a lot of my childhood favorites in german anymore and streams are compressed-to-death (and DRMed), i had a streak of preservia. Which is why i rip a bunch of discs from the library on Linux (yes, legally not ok, but morally just ease of access, i wouldn't sell them). Since it's only to watch them when nostalgia hits, i want them in a ready-to-watch format, chose AV1 webm for small size. My burner is LibreDrive-ok ootb, meaning makemkv goes automatically in that mode.

I have the discs for a limited time, so i used to use dvdbackup for DVD and later feed the folder to handbrake for conversion. Now i got a bunch of blu-ray:

ripping one takes even longer; whole 25 hours; i don't have the time for the whole LotR series with bonus disks.
makemkvcon backup needs only about 2 hours per disk, but the resulting folder is 80 GB big; i have only about 250 GB free space ** and the makemkv backup somehow has no audio streams, while handbrake does

While i write this, handbrake is loading the chapters (that alone needs more than 1 hour for blu-ray); i'm trying if a lossless FFV1 mkv conversion (for later re-conversion) takes less long.

Now:

Any better approach?
Any way to fix makemkv having no audio? (i could juggle with external disks) I think i have all libraries and the KEYDB.cfg.

Edit: nope, handbrake suddenly has unable to decrypt unit (AACS)

What's wrong with http://makemkv.com/? I've used it for years for lossless backup DVD/BD and no issue.

Yeah, the makemkvcon backup command had missing audio, so i assumed, it was the case for the graphical interface too. But it works fine, about same speed and i just discovered, that you can open the resulting mkv on handbrake and choose audio channels and whatnot as if it was the disc itself. Only issue with duplicates (confirmed via video-compare , great tool with dynamic move-mouse split) but that's what the checkmarks are for. I'll mark it as solved.
