Multimedia Problem: Maybe you don't have enough rights...(e.g: no disc in drive)

[Rog131]

If you get something like this:

Xine Message - Kaffeine Player

The source can't be read.

Maybe you don't have enough rights for this, or source doesn't contain data (e.g: no disc in drive). (/dev/dvd)

Check your dvd. Konsole:

ls -l /dev/dvd*

lrwxrwxrwx 1 root root 4 2008-04-09 17:50 /dev/dvd2 -> scd0
lrwxrwxrwx 1 root root 4 2008-04-09 17:50 /dev/dvdrw2 -> scd0

Problem could be that media players are looking /dev/dvd => "The source can't be read" error.


This could be related to the Deja Vu


You could:

K > Multimedia > Kaffeine

Kaffeine > Settings > Xine Engine Parameters > media (Beginner Options)

There is: dvd.device, device used for DVD playback. default is /dev/dvd, change it to the /dev/dvd2


Same thing with the other players (mplayer...)


Or simply make symlinks /1/

Konsole:

sudo ln -s /dev/dvd2 /dev/dvd
sudo ln -s /dev/dvdrw2 /dev/dvdrw

so now:

Konsole:

ls -l /dev/dvd*

lrwxrwxrwx 1 root root 9 2008-04-09 18:22 /dev/dvd -> /dev/dvd2
lrwxrwxrwx 1 root root 4 2008-04-09 17:50 /dev/dvd2 -> scd0
lrwxrwxrwx 1 root root 11 2008-04-09 18:22 /dev/dvdrw -> /dev/dvdrw2
lrwxrwxrwx 1 root root 4 2008-04-09 17:50 /dev/dvdrw2 -> scd0

Permanent fix

If you make symlinks to the /dev folder they will be erased when you turn the power off.

Kubuntu use udev. udev wiki:

udev is the device manager for the Linux 2.6 kernel series. Its primary function is managing device nodes in /dev. It is the successor of devfs and hotplug, which means that it handles the /dev directory and all user space actions when adding/removing devices, including firmware load....

man udev

man udev

UDEV(7) udev UDEV(7)

NAME
udev - dynamic device management

DESCRIPTION
udev provides a dynamic device directory containing only the files for
actually present devices. It creates or removes device node files in
the /dev directory, or it renames network interfaces.
...
CONFIGURATION
All udev configuration files are placed in /etc/udev/*. Every file
consists of a set of lines of text. All empty lines or lines beginning
with ´#´ will be ignored.
...

/etc/udev/rules.d/70-persistent-cd.rules have lines:

ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:09.0-scsi-1:0:0:0", SYMLINK+="dvd2", ENV{GENERATED}="1"
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:09.0-scsi-1:0:0:0", SYMLINK+="dvdrw2", ENV{GENERATED}="1"

Pressing Alt + F2 and kdesudo kate /etc/udev/rules.d/70-persistent-cd.rules

Changing "dvd2" and "dvdrw2" to the "dvd" and "dvdrw". Restarting.

ls -l /dev/dvd*

is now:

lrwxrwxrwx 1 root root 4 2008-04-09 22:56 /dev/dvd -> scd0
lrwxrwxrwx 1 root root 4 2008-04-09 22:56 /dev/dvdrw -> scd0

Re: Multimedia Problem: Maybe you don't have enough rights...(e.g: no disc in drive)

I have libdvdcss and all of the win32 codecs installed. I have every piece of software I need to play DVDs. Then I came across this thread thinking it would finally solve my problem. I followed two of the three instructions above (not the permanent fix) and it's still a no-go. I'm still getting the "no rights/no disc in drive" message. It wants to install the libdvdcss codec (which I already have installed). Once I go through the installation and try to play it, it goes back to install it again. It's locked in a loop.

In Settings>xine engine parameters>beginner options (decoder)> I have usr/lib/codecs as the external path to Win32 codecs. Is there another setting that should be used instead?

Re: Multimedia Problem: Maybe you don't have enough rights...(e.g: no disc in dr

I have libdvdcss and all of the win32 codecs installed.

Do you have ?:
libdvdread3 - library for reading DVDs
and
libdvdcss2 - Simple foundation for reading DVDs - runtime libraries

Is there another setting that should be used instead?

Maybe this helps: Topic: DVD playback fails even with all codecs etc installed

- Testing media players directly, should start to play DVD or give meaningful error message. That "The source can't be read / do you have enough rights" isn't really helping .

Re: Multimedia Problem: Maybe you don't have enough rights...(e.g: no disc in drive)

I got this problem too, but I find that it is due to lack of memory, I run Kubuntu on a 440M machine playing DVD always a problem, I reboot and it works again for a while until other apps eat up resource.
