Rendering Crashed Messages - 0.8.2.1 on SuSE 11.4

I have Kdenlive loaded from Packman, Version 0.8.2.1
Using KDE Development Platform 4.7.4 (4.7.4) "release 11.
MLT ver is 0.7.6-1.6, also from Packman
Suse is
Linux PVE-LinuxSRV5 2.6.37.6-0.9-desktop #1 SMP PREEMPT 2011-10-19 22:33:27 +0200 x86_64 x86_64 x86_64 GNU/Linux.

I am new to kdenlive, learning the ins, outs and options.
I have a simple project - A color background Title clip that transitions (dissolve) to three MOV files loaded from my Canon 550A (T2i) camera.
These MOV clips are H.264/AVC/MPEG-4 AVC/MPEG-4 Part 10, 1920x1088 at 29.97 fps.

The project plays OK in the Project Monitor window.

I am trying to render to a DVD, selected NTSC 16:9 VOB, Full Project in the Render_Project tab.
Output file is a .vob file.
Rendering proceeds with a few messages "Using network protocols without global network initialization. Please use avformat_network_init(), this will become mandatory later." which from reading this forum are just warnings.

The Progress bar advances, but when near (or at?) 100%, The job status changes to "Rendering Crashed"

I had started kdenlive from a console window to capture stdout.
Messages on stdout at the end of the rendering process.
"Rendering of /home/carl/Projects/kdenlive/cjm620_622_624_wed.vob aborted, resulting video will probably be corrupted."
I do see in /var/log/messages a line:
"Dec 21 09:22:07 PVE-LinuxSRV5 kernel: [67290.237929] melt[14481]: segfault at 0 ip 00007f350df742a9 sp 00007fff026765b0 error 4 in libc-2.11.3.so[7f350defc000+164000]"

The output file (xxx.vob) plays OK in xine.

Is there an explanation for the crash message/segfault?
Does 'melt' output any other log file? I don't see any.

If of use, here is the script startup (from stdout):

Hi

I had the same problem with 11.4 and now with 12.1. I notified the good guys from Packman. There released promptly the very latest factory version....but the problem persist...???

The thing id that the output file is playable and can be edited.

Don't know what the answer is.

cheers

Hello,
I had same problem; same OS version and Kdenlive 0.8.2.1.
Thanks for help

Hello,

It was a MLT problem that occur when jack audio is installed.

If you don't use jack, you can use this command for disabling the library.

mv /usr/lib64/mlt/libmltjackrack.so /usr/lib64/mlt/libmltjackrack.so.BAK

hello

i have same this problem!!!!
but i wanted to know: what is distro works 100% video rendered: kubuntu? mint? arch linux? which is work 100% with last version kdenlive?

hello cyp: render crash to 99% this is problem true of JACK? are you try to disable JACK and work render to 100% as perfect?

thnak you

Hi

Yes it's rendering to 100% without libmltjackrack.so.

JACK causes lot's of problem with MLT on OpenSuse (http://www.kdenlive.org/mantis/view.php?id=2439) and a few other distro (on Archlinux for exemple https://bbs.archlinux.org/viewtopic.php?id=133503 )

Hi, im having the same issue, but im using ubuntu and kdenlive (0.9)
i just try to disabled this file but the same problems occours again...
any ideia?

Kdenlive 0.8.2.1/ Ubuntu 12.04 64 bits
Unable to render anything, in any output format. Kdenlive crashed
What I did:
Tried to purge, update, reinstall without improvement.
Removed the file home/user/.kde/share/config/kdenliverc
Then started kdenlive from console with: padsp kdenlive
I can render perfectly now
Hope it will solve some issues
