kdenlive 0.8.2: Rendering aborted, resulting video will probably be corrupted.

Yesterday evening, I downgraded all packages for melt and mlt-framework from version 1:0.7.2-0.0
to version 0.7.2-1.

But unfortunately, this didn't helped. Rendering is still crashing during the process :-(

Other versions are not offered via apt-get.

Any other ideas (except of compiling melt by myself) ?

regards
Andreas

G.Marco, thanks for your reply, but what do you mean with "you could render to script" ?

Today, I made an update to version 0.8.3 of kdenlive.
But with both a.m. versions of melt, the process of rendering crashed.

Then, with version 1:0.7.2-0.0 of melt, I generated the script as mentioned.
First I started the saved script via kdenlive-gui => process crashed.

Then tried to run the script via console.
Script stopped immediately after start.

The I added "-verbose" to the script and when I started it, an preview window appears, but no file was written to hdd and after some seconds, the process stops.
Process is always stopping at a specific scene at the movie, but the scene contains nothing special like effects, etc.

Here is the complete console output:

Do you mean that part of it?
------------------------------------------------------
/usr/bin/melt square_pal avformat - /home/andreas/kdenlive/scripts/Skript001.sh.mlt file:///home/andreas/kdenlive/projekt.mpg f=mpeg acodec=mp2 ab=384k ar=48000 vcodec=mpeg2video minrate=0 b=25000k bf=2 b_strategy=1 trellis=1 aspect=@4/3 pass=2 progressive=1 threads=1 real_time=-1
------------------------------------------------------

If I execute that command in the console, I'm getting several errors like:
------------------------------------------------------
bash: /usr/bin/melt /home/andreas/kdenlive/scripts/Skript001.sh.mlt: File or Directory not found
------------------------------------------------------
The file exists, but with 0 byte it is empty.

Melt is installed correctly, I tried the command line you mentioned,
but it failed again (always at 4 percent).
As error message, it shows (in German):
----------------------------------------------
Speicherzugriffsfehler147, percentage: 4
----------------------------------------------
I guess, that "segfault" or "segmantion fault" is the correct translation.

I googled for "Speicherzugriffsfehler147 kdenlive" and got a result, that kdenlive in version 0.7.7 had problems with opening "old" projects from version 0.7.6.
http://www.kdenlive.org/mantis/view.php?id=1449
but now we are on version 0.8.3 and my project is rather new (I started with version I dont know, 0.8 ?, the version that is installed with a new stock debian wheezy installation).

Then I added a "-verbose" to the a.m. command line.
The output is not that "verbose", that I expected :-)
---------------------------------------------------------

Ok, I installed the Gnu-Debugger GDB and run the command you posted.
Nothing special happened and a prompt appears, showing a (gdb) prefix.
Then I tried different commands like:
---------------------------
r+
"r"+
"r" +
help
all commands shown in help-command
---------------------------
but all with no success. For all commands, I'm getting a "undefined command: "COMMAND". Try "help".
After that, I quit the gdb and returned to my normal prompt.

Then I re-ran your command and got to the gdb-prompt again.
Then I ran the melt-command in another terminal window again and got my crash after 4 percent.
After that crash I returned to the debugger and tried all mentioned commands (r+, "r"+, aliases...) again,
but every time I received the same error message.

Marco, thanks for your help, but is this a computer specific problem on my side or is this a bug somewhere in the mlt-installation?
Or do you think, that I have here a new bug?

One more question: are there other possibilities to render my project ?
Maybe also in the "not-linux-world" if needed.

Thanks for all your help, ein fettes "Merci" nach Berlin.

Andreas

Yesterday, I desperately tried again to render my project.
Of course, with no success, because no new version was installed.
Rendering crashed at the same point as before.

Today, I was reading the "/var/log/messages" to look for a minor error regarding my network harddisk drive.
And then I found this error message from yesterday:
------------------------------------------------------
Jun 5 20:03:55 debian kernel: [22763.450569] melt[8161]: segfault at 8 ip b773a8c0 sp b060dcd0 error 6 in libc-2.13.so[b762b000+153000]
------------------------------------------------------

Can this error message help to get rid of this rendering crashes?

Regards
Andreas

Hm, today I got the update from debian-sid for:
- melt and all libmlt 1:0.7.2+git20110530-0.1
- kdenlive 1:0.8-4.2

With my old saved project from the previous versions I got the rendering crash at the very same 4%.

Then I set up a new (smaller - for testing) project and tried to render it.
The rendering process reached 99% (or maybe 100%), but in the end, I still received the crash error notification.
The rendered mpg2-file seems to be ok.

Later this day, I will try to get my old saved project redone in the new kdenlive version.
Maybe the crash comes from the saved project file ??

I'm a little bit confused, but I will try to go on...
