Its region mask is zero, meaning it's playable everywhere. The message is the same when playing any non-region-restricted DVD (it does not have to be ripped).
In the message, the 8-bit region mask is sort of hidden inside the 32-bit long value*.
Here's what running mpv dvd://
said about four different commercial DVDs I have:
libdvdnav: DVD disk reports itself with Region mask 0x00fe0000. Regions: 01
libdvdnav: DVD disk reports itself with Region mask 0x00fd0000. Regions: 02
libdvdnav: DVD disk reports itself with Region mask 0x00e50000. Regions: 02 04 05
libdvdnav: DVD disk reports itself with Region mask 0x00000000. Regions: 01 02 03 04 05 06 07 08
In the first example, the region mask 0xfe
(0b11111110
) means regions 8 to 2 are masked:
It's only playable in region 1. (Only the rightmost bit is zero.)
The inverse (one's complement) of that mask, 0x01
(0b00000001
), would mean the opposite: Region 1 is masked, it's only playable in the other regions.
*: It could be some sort of debug thing or an oversight why it's displayed like this. Although the logic doesn't change, it only reveals itself when there's a non-zero mask (the first three examples).
0x00000000
and0
are the same number.0x00000000
isn't simply "the region mask as a number", instead, the eight bit mask is at the position marked..
in0x00..0000
in that message.
