K9copy Segmentation Fault 11

Postby Deminar on Mon Jan 14, 2013 9:25 pm

Hi everyone,
I am hoping to get a bit of help. I am not an expert but I can usually figure my way out of stuff. However, I hit a wall this time. I used to run Ubuntu but moved to Mint Nadia (14) with the MATE desktop. I used to use K9copy to backup my kids's favorite DVD but since I moved to MINT I haven't been able to do a single one. I can decrypt the DVD files and save them on my computer but I can never write them to a DVD without the segmentation fault. Here's what I have done:

I have installed all the libdvdread4 (including the libdvdcss2), the ubuntu-restriced-extras, the libdvdcss-dev; libdvdnav-dev and libdvdread-dev. If it makes a difference, I also have the ffmpg stuff installed. Because everything failed, I purged everything using the sudo apt-get purge on everything. I did the autoremove for any unused files left. I re-installed everything fresh and still the same segmentation fault 11. It doesn't matter if I do an ISO or if I just decrypt the VOB files in the temp folder. (I did notice that I had to remove the (-caption) from the start menu for the application to launch.) If there is any further information you require, please let me know and I will provide. I searched all the forums for several days and no threads were able to guide me through a resolution. The most popular thread was for Ubuntu and it was marked as solved but it's far from solved for me.

So here are the backtrace content and please, can anyone help me figure this out?

I don't have a definitive answer for you. The following is a "reach" suggestion... :)

One thing you might want to check out is the cache directory that K9copy is putting files into. Insure that it is large enough and permissions are set correctly.

If it helps, this is how the application crashes:

I open the K9copy (or the assistant), I pick the folder where I saved the DVD files and when I click next, that's when I get the segmentation fault.


Thank you, I will look for those folder attributes and post back my findings here.

Have you tried running k9copy from a terminal to see if it outputs any useful error messages?

Hi,
I have and always obtain the same results. The application launches perfectly. I select my source folder and when I click next, the application crashes with Segmentation Fault 11.

Are you saying you can create an ISO? If so, can you just run k3b or whatever burning software you have on mate and burn the image to a dvd?

I just installed k9copy on my mint KDE 13 system and did a test run on a DVD and saved a copy as an ISO. Then burnt it with K3B...

Seems fine. On my KDE system these files were also installed :-

apport (version 2.0.1-0ubuntu17.1) will be installed
apport-hooks-medibuntu (version 2) will be installed
apport-symptoms (version 0.16.1) will be installed
dvdauthor (version 0.7.0-1.1build1) will be installed
ffmpeg (version 4:0.8.4-0ubuntu0.12.04.1) will be installed
k9copy (version 2.3.8-1) will be installed
libav-tools (version 4:0.8.4-0ubuntu0.12.04.1) will be installed
libavdevice53 (version 4:0.8.4-0ubuntu0.12.04.1) will be installed
libavfilter2 (version 4:0.8.4-0ubuntu0.12.04.1) will be installed
liblzo2-2 (version 2.06-1) will be installed
mencoder (version 2:1.0~rc4.dfsg1+svn34540-1+medibuntu1) will be installed
python-apport (version 2.0.1-0ubuntu17.1) will be installed

Re: K9copy Segmentation Fault 11

Hi, so I looked at the folder and size shouldn't be a problem unless there is something I am not aware of. The VOB files are not too big or unusually big. The permissions are create and delete files. It is not rooted and I shouldn't need to do that. Next step is to try it from the boot disk so it can mimic the single user mode.

I'll try again to decrypt the files to an ISO file and try to write it with K3b. It failed before. The disk is just not readable for some reason. Either my dvd player or linux.

I also confirmed that all the proper packages are installing like Grepnix was saying.

I tried doing the image and copying it with K3b and it still doesn't work. Now I don't have the segmentation fault because I don't use k9copy but the image burns successfully, however nothing can read the dvd.

Also, I have checked the region setting of my hardware and that's correct. I think I will have to give DVD95 a try but I had mixed results with that one. I would rather find a way to get K9copy to work as I loved the application.

Thank you for your help and please don't give up. I want to find a way to fix this.

Is there anything different about the DVD media that you are using compared to what worked before? Different make etc?

Update,
I still can't use K9copy for anything other than creating the ISO files and after a little bit of investigation, I was able to successfully copy the ISO using K3b. I will attempt to repeat that tonight once I am off of work.
I am using a new DVD drive. The ones I had before were older ones and were using the old power connectiors and IDE cables. This one, along with the new computer, is using SATA connections for media and power. I may install a copy of Ubuntu in a Virtual Box and see if I can successfully run K9copy. If I can't, then it would have something to do with the hardware versus the OS.

In the meantime, if you need any other reports of my configurations, either hardware or software, let me know and I will provide.

Regards,

Me.

I gave up.

Thank you for your tips.

I resorted to image the disk using K9 and copy it using K3b. (Works for all except newer Disney DVDs.)

Thats the way I've always done it to be honest... I did have some problems with some DVDs and someone suggested that I use vobcopy.

I installed it from the repository and ran their suggested command line (First checking that /dev/sr0 was my dvd drive via ‘fdisk -l’ and changing the output directory to my own)

Code: Select all
vobcopy -b 7.5m -l -i /dev/sr0 -f -o ~/Movies/


This produced a large decrypted file with .VOB as the extension. I ran that through Devede which seemed to hang at the point it creates the .iso file. Undeterred I just renamed the .VOB to .mp4 and tried again. This time it worked and it produced a successful backup! Not sure why it had to be renamed. Maybe if I’d had more patience and waited the first time it would have worked anyway…

I think perhaps you solved this issue by updating your hardware. I have found issue with some dvd burners which are related to them being too old to make copies of the latest movies or data disks. Updating codecs is often required. I have to do that often on my windows computer running XP which I use mainly to burn my avi files to disk.
I had been using a dvd drive to burn the avi files on my computer and had chance to have to use it to burn dual layer dvds for a project I was doing and found that my computer/dvd combination was not up to the task. It should have easily burned the dual layer disks as it was not an old dvd burner, but it would fail always when trying to burn a dual layer disk. I tried two or three brands of dvd-9 disks and all failed. When I used the burner on my linux machine to do the same task and using the same brand but different model of the same dvd burner, it would work fine.
I still have the same issue with the other computer and burner after attempting updating etc, so it could be something to do with the dvd burner's laser of mechanical operation.
It is nice to have another computer around that can test for the other one and see if it is the OS or the drive or the software causing the issue.
I hope it all works out ok now, but I think you have found the reason for the failure you had in the past.
