As explained in the above reply. The following command cannot be executed on LE 9.2.8 system

"mkudffs --utf8 --blocksize=2048 --media-type=bdr --udfrev=0x0250 --lvid=Backup2 --vid=Backup2 /dev/sr0"

I also tried LE 10.0.1 & Raspberry Pi OS, and it was the same situation.

and i think the BDrom DISK, that need use the custom command method to read it.

So ask everyone,

How to set mkudffs to execute on LE 9.2.8 system (RPI 4B) ...

Thank you also chewitt for your reply

============================

i think mkudffs maybe to Re-compiler on LE ..

But I don't know how to use Linux system...

just only follow Someone can provide the SOP guideline .

Step by step follow the instructions

Thank all...

=====================================

In addition, I tring use GOOGLE to do some thing ...

and Find the following command reference

But this instruction cannot be executed in LIBREELEC 9.2.8 system

No longer can create usable UDF images - Pali/Udftools

UDF formatting a BD-RE under Linux - media type "bdr" unknown?

This is on Ubuntu 20.04.1, Pioneer BDR-XS07, 50 GB BD-RE (multiple discs from different vendors tested). Formatting the disc with UDF version 2.50 works: $…

superuser.com

Formatting the disc with UDF version 2.50 works:
$ sudo mkudffs --utf8 --blocksize=2048 --media-type=bdr --udfrev=0x0250 --lvid=Backup2 --vid=Backup2 /dev/sr0

====================================

If you need me to help test related commands, or provide related system information.

Please guide me again. I can follow the instructions and provide information on the results of the execution.

Thanks for the assistance.

Thanks for your guidance. I can try it

But I am new to linux system...

Can the above settings explain the edited path and file name..

thanks

First of all, my English is not good, so let me say sorry first.

After testing for about a day,

For the above questions, the preliminary understanding is as follows.

BD-ROM (USB-DEVICE) is recognized and installed by the system.

The main problem is the problem of inserting the <disc>.

Insert a general DVD teaching disc, it can be recognized normally, and the disc file path can be accessed. (just like USB-HDD).

But if you put in a BD-R(25G) disc (UDF 2.6 format), it will not be recognized.

that BD-R Disk is burned into a data disc (UDF 2.6 format) with CDBurnerXP Tools(Ver 4.5.8.7128) .

BD-ROM (USB-DEVICE) and BD-R (25G) discs are installed on win 7 & 10 systems

It can recognize and read the disc data normally.

Does LIBREELEC is not support BD-R UDF 2.6 format discs?

OR How can i do some thing to fix this problem.

Thank all..
