[xine-user] Re: raw

[P.C. C. <pc...@al...>]

Hi there,

I am using the raw device.

The first thing is to find the raw executeable.  I am using Debian. It is part of util-linux but raw does not come with precompiled
packages.  (Some older kernel probably did not support that.)

I took the source, cd'ed in disk-utils, did a make raw and copied it to /usr/bin (and man pages to /usr/man/man8).

In raw.c:

#ifdef OLD_RAW_DEVS
#define RAWCTLDEV "/dev/raw"
#define RAWDEVDIR "/dev/"
#else
#define RAWCTLDEV "/dev/rawctl"

The control device is called /dev/rawctl in newer system.
My cdrom/dvd is at /dev/hdc.
What I did was:

cd /dev
mknod rawctl c 162 0
mknod raw1 c 162 1
raw /dev/raw1 /dev/hdc
it would response with

/dev/raw/raw1:  bound to major xx, minor y

then

ln -s raw1 rdvd

Then without putting anything into the drive, try cat /dev/rdvd

it responds

cat: /dev/rdvd: No medium found

(not the normal response: No Such Device)

I don't need to mount the dvd before playing.

By the way, if you are mounting a dvd, please mount it as udf.  You need to turn on the udf support in the kernel to do that.

I don't think encrypted media would make any difference.

Go luck.
