How to burn a Blu-ray disc from a backup on Linux ?

[georgesgiralt]

Hi Guys,
I'm posting here because I do not know where to ask.
I've a Blu-ray I love a lot and the disc id dying (a lot of medium errors in a computer drive and seizures in a "plain" player).
Fortunately I've made a backup with Make MKV so I've got all the files I need.
As the size is less than 22 GB, I bet I can write a new Blu-Ray to continue enjoying my film.
So my question is how to make a physical Blu-Ray from the backup ?
Any clues ?
Thanks a lot in advance for your help.
Have a nice and bright day.
P.S. : I'm using the 22.04 LTS Ubuntu and, even retired, own a degree in computer science, so not a plain newbie...

Did you back up to folder or to mkv?

[georgesgiralt]

A folder.
I've a bunch of directories under it. One of them, STREAM contains a lot of .mts files some of them big.

You need to burn only the BDMV and CERTIFICATE folders to a BD-25. File system UDF 2.5. I'm not familiar with Linux burning programs but UDF 2.5 seems to be an issue. Install Wine and use Imgburn.

OK. Thank you.
Will try to find something.
HAve a nice day.

Listen to Coopervid, Imgburn really is your best option. UDF and all other things related to optical media are "vintage". The UDF 2.5 spec. is over 20 years old! I wouldn't hold my breath for anyone to develop something new for it on Linux or even on Windows. I feel your pain though, I have a similar problem with all things Firewire (IEEE 1394).

Optical media is the new vinyl.

There is a better option for burning UDF 2.5 in Linux than a Windows program through Wine.
Just use xorriso! It's available for most distros; Ubuntu, Fedora, and Arch.

I do have a question, though. How do you get MakeMKV to copy the raw files off a Blu-ray?
I've only just been burning the MKV files to a BD-r DL.

Use MakeMKV's backup option. After you start MakeMKV and put a blu-ray into your optical drive but before you click the big disc icon, click the icon at the top that is a yellow folder with a green arrow.

I actually used :

Code: Select all

mkisofs -udf -iso-level "3" -input-charset "utf-8"-V <name of the disc> -allow-limited-size  -o <name_of_file_to_create>.iso <source_directory>

to generate the ISO file. Then I burned it to a BD using my favourite burning software. (I do not do it on the command line anymore, and can' remember how I did it long ago....)
The burned Blu Ray pays fine in my computer and on the set top box I use to play ordinary Blu Rays.
Hope this helps

xorriso doesn't support UDF of any kind.
