Re: [Bug-xorriso] please help to compile arm cross platform

[Thomas Schmitt]

Hi,

> can you please drop an example how to create blueray iso from BDMV folder?

BDMV ... sounds like Blu-ray movie stuff.
My knowledge about DVD video and BD video is very limited, i fear.
I'm into data backups, originally.

You will probably need an UDF filesystem for that, not an ISO 9660.
Afaik, there are special constraints about file names and the
sequence of file content block addresses.

Unless your intended Blu-ray player can pick its video files from
an ISO 9660 filesystem, xorriso will only be of help with the job
to copy the readily formatted UDF filesystem onto BD-R (if adapter
SG_IO or libcdio have been compiled successfully).

That said: To wrap /some/directory as root directory into an
ISO 9660 filesystem, and to burn it onto a blank BD-R or BD-RE,
do

  xorriso -outdev /dev/sr0 -map /some/directory /

BD-R will stay appendable for further ISO 9660 sessions.
To make them really read-only, use

  xorriso -outdev /dev/sr0 -close on -map /some/directory /

BD-RE stay appendable until they are full.
If you want to re-use a BD-RE from scratch, pseudo-blank it
before writing to it:

  xorriso -outdev /dev/sr0 \
          -blank as_needed \
          -map /some/directory /

There is xorriso-tcltk which will show the xorriso commands
as emitted when you hit one of its GUI elements.
See
     xorriso-1.3.4/frontend/README-tcltk


> or I have to use option <act as mkfsiso>? :)

xorriso -as mkisofs does not support option -udf, which on mkisofs
could produce an UDF filesystem suitable for DVD video.
(But afaik, mkisofs -udf does not comply to Blu-ray video specs.)

In general, the -as mkisofs emulation is intended to ease migration
of scripts which used mkisofs before. Quite popular among producers
of bootable ISOs.


Have a nice day :)
