DVD playback fails even with all codecs etc installed

[humanebiscuit]

Hi,

Been searching the forum for hours and still can't make it work...any help really appreciated!

Recently changed from ubuntu to Kubuntu Gutsy.

Basically DVD playback doesn't work in anything I've tried (Kaffeine, VLC or mplayer). I Prefer Kaffeine if possible (worked fine with ubuntu)

I've been through the HowTo on playing commercial DVDs in Kaffeine (twice, infact), and have everything installed, but still get the error 'Source can't be read, maybe you don't have enough rights or source doesn't contain data (eg no disc in drive). (error reading from DVD).

Interestingly, I found a post that suggested following these instructions
help:/kubuntu/musicvideophotos/video.html#dvdplayback (paste into konqueror)

They don't work because the command is wrong. However

sudo /usr/share/doc/libdvdread3/install-css.sh

does work. (still no playback though). BUT as soon as i do it, adept pops up saying that dvdcss2 has an upgrade. So I upgrade it, playback still doesn't work. And then if you install libdvdread3 command again, Adept pops up again, offering to upgrade dvdcss2, ad infinitum...

Apart from this small anomoly (which might not be one at all?) I'm stuck. The hardware works, because it identifies it as a DVD and knows what its called. I'm in the UK, just incase that might be an issue with regions?

Any ideas gratefully received!

Thanks

Will

Re: DVD playback fails even with all codecs etc installed

Wow. I have no encrypted DVDs at hand now but there should be no way VLC wouldn't work - check that it's not a disk problem, i.e. try the disk in a different drive and/or try a different encrypted disk (or a different OS/virtual machine). I had a DVD (not sure if it was encrypted) that would just crash/freeze VLC (or any program attempting to read it) on windows - I used Nero CDspeed back then to check the disk, not sure what do I use in Linux though (fsck?).

Alternatively, if it's the rights that are a problem, check your rights on the DVD drive and the mount point:
the device (/dev/scd0 on my PC) should be (user:group) root:cdrom, rw-rw----
mount point is user:root r-xr-xr-x
and of course, check that you are a member of cdrom group.

DVD playback fails even with all codecs etc installed

What are all codecs?

Have you installed libdvdcss2?

[blobfish]

Re: DVD playback fails even with all codecs etc installed

When you shove the dvd in, do you get the icon on your desktop showing the mounted filesystem? Can you see the files with konqueror? Can you kaffeine, file open, browse to and play a vob file?

Re: DVD playback fails even with all codecs etc installed

Hey everyone, thanks for the replies,

Myxal, I don't think it's the dvd - it works on a normal DVD player, and I get this problem with every encrypted dvd i've tried. I got hold of an unencrypted one and that works fine though, so its obviously something to do with encryption.

Could you explain the second half of your post though, because it could be that - about checking the rights on dvd drive and mount point? Sorry, i've never done that kind of thing before, how do I do it?

Arochester - sorry, wrong terminology. I've got dvdread3, win32 codecs, libdvdcss2 and libxine1 bits all installed...

Tanderson - yep the icon appears, and I can browse the files with Konqueror. When I try playing a vob file in kaffeine nothing happens though (it says 'stop' immediately.) Any ideas?

Thanks again everyone

Re: DVD playback fails even with all codecs etc installed

Testing media players:

Kaffeine
Start kaffeine in the konsole

kaffeine --verbose

--verbose Output xine debug messages

and kaffeine installation check

kaffeine -w

-w, --wizard Run installation wizard

Here it tells:

Kaffeine-Xine...
Ok.
KDE...
Found version: 3.5.8
Ok.WIN32 Codecs...
Ok.
libdvdcss...
Ok.
DVD Drive...
Ok.
DVB-Device...
No DVB-Devices found. The DVB related functions will be hidden.
Distribution...
Ok.
RESULT: All ok!

VLC
Start VLC in the konsole:

vlc -v2

-v, --verbose <integer> Verbosity (0,1,2)

Testing media players directly (should start to play DVD or give error message):

Kaffeine

kaffeine --verbose dvd://1

VLC

vlc -v2 dvd://

mplayer

mplayer dvd://1

About help

kaffeine --help

and

man kaffeine

vlc --help

and

man vlc

mplayer --help

and

man mplayer

Afterthought

If you use:

logsave output.txt kaffeine --verbose dvd://1

Output will be redirected to the file.

man logsave

LOGSAVE(8) LOGSAVE(8)

NAME
logsave - save the output of a command in a logfile

SYNOPSIS
logsave [ -asv ] logfile cmd_prog [ ... ]

DESCRIPTION
The logsave program will execute cmd_prog with the specified argu‐
ment(s), and save a copy of its output to logfile. If the containing
directory for logfile does not exist, logsave will accumulate the out‐
put in memory until it can be written out. A copy of the output will
also be written to standard output.

If cmd_prog is a single hyphen (’-’), then instead of executing a pro‐
gram, logsave will take its input from standard input and save it in
logfile

logsave is useful for saving the output of initial boot scripts until
the /var partition is mounted, so the output can be written to
/var/log.

Re: DVD playback fails even with all codecs etc installed

Hey,

Running

kaffeine -w

says that

DVD Drive...
Can't check DMA mode. Permission denied or no such device: "/dev/dvd"

Any ideas what I do about that? Sorry - my linux knowledge is patchy!

also, just incase, running

kaffeine --verbose dvd://1

gives the output below. I've copied the second half of the output, that seemed more relevant? thanks again.

Re: DVD playback fails even with all codecs etc installed

Permission denied or no such device: "/dev/dvd"

What tells:

ls -l /dev/dvd

Here:

lrwxrwxrwx 1 root root 3 2008-01-04 13:15 /dev/dvd -> hdc

It is link to the real hardware (hdc).

Or do you have /dev/dvd1 ?

ls -l /dev/dvd1

or

ls -l /dev/dvd*

[humanebiscuit]

Re: DVD playback fails even with all codecs etc installed

With

ls -l /dev/dvd

I get

lrwxrwxrwx 1 root root 4 2008-01-04 13:34 /dev/dvd -> scd0
->

Does that look right?

I just tried a different encrypted DVD and it worked fine, so I guess it must only be some DVDs. Weird that the difficult one worked OK in a normal DVD player (box attached to the telly) though.

Are there some forms of encryption that libdvdcss2 can't deal with?

Re: DVD playback fails even with all codecs etc installed

It's more likely, that the Region Code on the one(s) that won't play are different than what is set as the default in the players and/or the DVD firmware on the physical DVD unit.

Yes, it should work.

But what is the solution

[humanebiscuit]

Re: DVD playback fails even with all codecs etc installed

Ah well, thanks for all the advice. Guess I'll have to make do with only watching some DVD's. If anyone finds out a good way to solve it though, I'd be really grateful if you could post it.

btw I don't think it's a region thing (the ones that work and the ones that don't are both region 2)

thanks again for trying - I think these forums are one of the best things about linux. Every other problem I've had I've solved by searching other posts...don't know where I'd be without them!

[Snowhog]

Re: DVD playback fails even with all codecs etc installed

Just a thought: the DVD(s) that won't play aren't HD (Blue-ray) DVDs by chance?

[humanebiscuit]

Re: DVD playback fails even with all codecs etc installed

good thought, but unfortunately not. Atleast they don't say so on the box...

[toad]

Re: DVD playback fails even with all codecs etc installed

Rog131 - where do you get all the info from Nice one!

Humanebiscuit - kaffeine refuses to play some of my DVDs also while VLC never fails! In particular I experience problems with the VIDEO_TS and AUDIO_TS structure, where I have to click on individual vobs in the video folder (regardless of whether I use kaffeine or vlc).

To cut a long story short - have you tried another media player?
