[DVDnav-discuss] Using libdvdnav on an ARM based NAS

Hi,

I have compiled libdvdnav 4.1.3  and libdvdread 4.1.3 for my ARM based
D-Link DNS-323 NAS (armv5tejl little endian).  I had no errors while
compiling either library.  However, I am getting a lot of errors while
running the menus example. In the menus.c source code, I replaced /dev/dvd
with the actual path to my .ISO file.  Here is the output when I run the
menus binary:

/mnt/HD_a2/source/libdvdnav/examples # ./menus
/mnt/HD_b2/Video/DVD/SERENITY.ISO
Opening DVD...
libdvdnav: Using dvdnav version 4.1.3
libdvdread: Using libdvdcss version 1.2.10 for DVD access

libdvdnav: DVD Serial Number: 3337a571

libdvdnav: DVD disk reports itself with Region mask 0x00000000. Regions: 1 2
3 4
 5 6 7 8

This ISO is CSS free.  I also compiled the same libdvdnav and libdvdread on
my Ubuntu Hardy setup and I do not receive any errors while running the
menus binary with the same .ISO I used on the DNS-323 NAS.  When compiling
other code for this NAS, I've seen issues with memory alignment in a couple
of different applications.  I'm not sure this is the issue here, but I
thought I would let you know.

Thanks,
John
