DVD : no medium found on /dev/sr0 when there is a DVD
I have a problem with Ubuntu 14.04 and playing DVD's.
After installing 14.04 I came to the conclusion that I can not play any DVD's. DVD's cannot even be opened as they are not seen by Ubuntu.
The data I have until now:
- In the install of 13.10 this was no problem, so this excludes a hardware problem
- It's on 2 installs on 2 different computers.
- It concerns a Ubuntu and Lubuntu install
- The different libdvd libraries are installed:
- libdvdread4 : version 4.2.1-2ubuntu1
- libdvdnav4 : version 4.2.1-3
- libdvdcss2 : version 1.2.13-0
- ubuntu-restricted-extras : version 60
- acidrip : version 0.14-0.2ubuntu7
- The dvd is found on
/dev/sr0
-
eject /dev/sr0
does work like a charm -
sudo mount /dev/sr0 /tmp/dvd
makes DVD to in but doesn't mount - The dvd is found on
/dev/sr0
-
lshw
on cdrom gives the DVD player with the<status=nodisc>
when there is a dvd in it! - playing a CD is no problem
-
ls -l /dev/sr0
gives :brw-rw----+ 1 root cdrom 11, 0 aug 9 20:20 /dev/sr0
- I am in group cdrom
- vlc doesn't work as doesn't acidrip for that matter or mplayer
- changing regions doesn't work as the computer thinks there's no disc.
- vlc doesn't have problems with encyption (region) but just can't open
/dev/sr0
- when using vlc as root it gives the same error, so it won't be a rights problem
vlc -vvv /dev/sr0
gives a lot and this:
libdvdnav: Using dvdnav version 4.2.1
libdvdread: Could not open /dev/sr0 with libdvdcss.
libdvdread: Can't open /dev/sr0 for reading
libdvdnav: vm: failed to open/read the DVD
[0x7f1d18000e78] dvdnav demux warning: cannot open DVD (/dev/sr0)
So now I am stuck with two installs of Ubuntu 14.04 which don't play any DVD's. Can somebody help and/or ask some questions which lead me to an answer?
Solution 1:
Try cleaning your DVD drive optical head. I had some flaky DVD recognition, similar symptoms, which got much better after cleaning the laser lens.
Solution 2:
Did you try running sudo /usr/share/doc/libdvdread4/install-css.sh
?
It is a " shell script to install libdvdcss under Debian GNU Linux, many DVDs use css for encryption. To play these discs, a special library is needed to decode them, libdvdcss. Due to legal problems, Debian and most Linux distibutions cannot distribute libdvdcss "
This script will also install VLC if necessary
I do read that you have libdvdcss2 installed already, but in my experience I had to run this script before I could play DVD's.
