How to get read permissions on a DVD-RW with UDF that was recorded from a DVD recorder?
I would like to watch old videos from a DVD-RW written with a DVD recorder, but it can't be accessed from Linux because it has no read permission:
Code:$ stat StorageLabs\ TinyUDF\ Volume/
File: StorageLabs TinyUDF Volume/
Size: 136 Blocks: 4 IO Block: 2048 directory
Device: 700h/1792d Inode: 1299 Links: 4
Access: (0000/d---------) Uid: (29999/username) Gid: (29999/username)
Access: 1970-01-01 01:00:00.000000000 +0100
Modify: 1970-01-01 01:00:00.000000000 +0100
Change: 1970-01-01 01:00:00.000000000 +0100
Birth: -Making an image from the disc doesn't help, since it is always mounted read-only.
Code:$ sudo mount DVD.iso ../UDF -o rw
mount: /media/username/UDF: WARNING: source write-protected, mounted read-only.
$ sudo chmod a+r /media/username/UDF
chmod: changing permissions of '/media/username/UDF': Read-only file systemAccessing the disc on Windows is trivial (it appears in the file explorer immediately) since it doesn't know Unix permissions.
How do I get read permissions on that UDF disc?
Do I have to resort to using 7z? (It happens to be able to read UDF images. While one could access some files using pipes (stdin / stdout), they are not seekable.)
