transcode failing within dvdrip

[nando]

I'm trying to pull the main track of a dvd, but the ripping stage never finishes. Looking at the logs, it's failing when transcode is trying to pull off the preview pane:

Sat Dec 2 01:32:58 2006 Start job 'Process preview frame - title #1'
Sat Dec 2 01:32:58 2006 Start job 'Grab preview - title #1'
Sat Dec 2 01:32:58 2006 Executing command: mkdir -m 0775 /tmp/dvdrip7339.ppm; cd /tmp/dvdrip7339.ppm; execflow transcode -H 10 --print_status 25 -o snapshot -y ppm,null -x vob,null -i /home/chamilto/dvdrip-data/zardoz/vob/001/ -S 8 -c 8-9 -L 1547829 && execflow convert -size 720x480 /tmp/dvdrip7339.ppm/snapshot*.ppm /home/chamilto/dvdrip-data/zardoz/tmp/zardoz-001-preview-orig.jpg && execflow convert -size 720x480 /tmp/dvdrip7339.ppm/snapshot*.ppm gray:/home/chamilto/dvdrip-data/zardoz/tmp/zardoz-001-preview-orig.raw && rm -r /tmp/dvdrip7339.ppm && echo EXECFLOW_OK
Sat Dec 2 01:32:58 2006 Job 'Rip - title #1' finished
Sat Dec 2 02:12:16 2006 Rip selected title(s) / chapter(s): 20% done.
Sat Dec 2 02:12:16 2006 Process title #1: 20% done.

I'm guessing dvdrip eventually gives up on this process because it's still hanging around in my process list. The status of dvdrip remains at "Grab preview - title #1". If I run the above command manually, it just chews up cpu for a while and then stops.

The preview images aren't a big deal. The transcode button won't come on unless it successfully completes the full rip, so if I restart dvdrip I'm able to transcode the file using ffmpeg. That'll run about two hours until it gets to about %99.9 and then it stops.

I've got four dvd's sitting on my desk right now, and two complete successfully, and two hang every time.

are the dvd's scratched? maybe trying doing just the dvdrip to check and see
I use vobcopy...like this

[shakti]

are the dvd's that dont work from the same distributer? Sony? I had some problems with sony dvd's, now i use dvdshrink in wine.

Well, it's not a sony. Vopcopy finishes fine and the disc doesn't look scratched.

I reran one of the dvd's and killed off the hanging transcode process. It threw up an error, and I didn't get a preview image, but I was able to use the transcode tab to crunch it down into an avi.

No dice for the other one. I kill off the errant transcode process that's trying to create the preview images, and get the same error message. It seems to have pulled the vob's ok and I can mplayer all of them no problem. However when I try to transcode them it gets to 99.67% on pass 1 before hanging on this:

Wed Dec 6 22:45:58 2006 Executing command: mkdir -m 0775 -p '/home/chamilto/dvdrip-data/headofstate/tmp' && cd /home/chamilto/dvdrip-data/headofstate/tmp && mkdir -p /home/chamilto/dvdrip-data/headofstate/avi/001 && execflow -n 19 transcode -H 10 -a 0 -x vob -i /home/chamilto/dvdrip-data/headofstate/vob/001/ -w 887,50 -F mpeg4 -b 128,0,2 -s 1.378 --a52_drc_off -f 24,1 -M 2 -R 1 -y ffmpeg,null --psu_mode --nav_seek /home/chamilto/dvdrip-data/headofstate/tmp/headofstate-001-nav.log --no_split -o /dev/null --print_status 25 && echo EXECFLOW_OK


I'm using the ffmpeg codec, so I'll try a different one and see if that makes any difference.

I get the same problem with the preview image generation failing. At this point the DVD has been ripped just fine and transcode is called to pull preview images out of the VOB's. The transcode command here:

i have the same problem...

I'm having a similar problem with dvdrip and transcode. It took a look at the stack of the transcode process and found it's calling usleep() from the endcode() function:

[neurosis]

Any updates to this? Fixes? I'm having the exact same problem..

I'm experiencing it as well.

Some (old) threads on the transcode mailing list discuss what seems to be this very issue. It seems to be a problem with threading (just like one of the previous posters suggested) and a workaround is presented, forcing it to use LinuxThreads instead of POSIXThreads. Here's one thread discussing it:
http://www.itdp.de/transcode-users/2005-02/msg00029.html

AFAIK, this is the same workaround as is now in dvd::rip, under preferences->miscellaneous->Workaround transcode NTPL bugs. Unfortunately, these are disabled for me. Trying the workaround "manually" seems to confuse the linker...

[azote]

same issue.... they seem to be disabled for me 2..... any solutions?

What do you want to emerge today?

if you think that a person is normal, it is because you do not know them well

[JasonB87]

Ok here's something to try. On the transcode tab disable Use PSU core.
I was trying to transcode videos and they kept hanging at 99% so I eventually tried a bunch of stuff and then came to this. After I disabled it, the file transcoded like a charm.

Let me know how it goes.

Just thought I'd throw this in as well; I was having a problem with dvd::rip failing in the transcode phase a little after 99% on the 1st pass and disabling 'Use PSU Core' did the trick. This is with transcode v. 1.0.7 and dvd::rip v. 0.98.9.

Yes, it's a year and a half later and the same problem still exists with transcode.

[Tuxenstein]

I'm also having this problem and even though "Use CPU core" is disabled for me by default (I'm assuming this is the setting everyone is referring to as "disabling" the CPU? If not, which other setting and/or where is it?) under "transcode", it still continues to present the same problem for me.
