Kdenlive 0.8.2.1/ Ubuntu 12.04 64 bits
Unable to render anything. 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

thank you for your replay
sadly your fix didn't work for me

It seems versions of Kdenlive in official repositories are deprecated. I found it is strongly recommended to install Kdenlive 0.9 packages using Sunab's alternative repository.
Try sudo apt-get remove kdenlive melt
Then reinstall using the command line in terminal (just copy and paste):
sudo add-apt-repository ppa:sunab/kdenlive-release && sudo apt-get update && sudo apt-get install kdenlive

then launch using command line
padsp kdenlive

Thank you for the replay

I tried to install\run the app like you said but still did not work

I have also tried the procedure but no succes.

However, it may be interesting to notify that I have two new installs of Ubuntu 12.04 not working while on a third PC, I did an upgrade to 12.04 instead of clean install
and no problem on that system.

The main difference I can see between (not working) new installs and (working) upgrade is:
- the version of MLT 0.7.7 instead of LT 0.7.8 on new installs.
- kdenlive v 0.8.2.1 (kde development platform 4.8.2) instead of v 0.9 (kde development platform 4.8.2)

Really buggy app but thing is when it finishes rendering(and crashes) i get rendered file in output directory that plays with no problem but i do not know if file is lacking something or not

Even I faced this issue with KDENLIVE 0.9 and Linux Mint Maya 64 bit Cinnamon edition. However the video was proper. Not sure why did rendering crashed.

I want to ask you something: What do you think is output file ok or still lacks something

Same problem for me, except since I upgrade to 0.9 the quality of rendering has dropped alot. Soo many bigs in this version. I'm probably going to have to ditch Kdenlive. The really need to release a stable version of this software.

Hi Levan7,

The output seems to be good, no lack of quality. (H.264 12k, 384kbps audio).

One more thing, this happened to me only once. I rendered two more videos after the crash. It went on fine.

Ok but it happens to me everytime i render

thank you for the comments

Hey, unfortunately rendering crashed for one more video. Again no loss of quality and video is fine

I'm also getting crashes at the end of the rendering process each time I try. But the video is displayed fine by my movie player. Is it really crashing?

These are from two videos I rendered today (Ubuntu 12.04, MLT 0.7.8, Kdenlive 0.9 Sunab, ffmpeg 0.8.1-4:0.8.1-0ubuntu1):

This is from the command line:

"Rendering of /home/funpro/Desktop/edu/fun programming/result/Fun programming 110b.webm aborted, resulting video will probably be corrupted."

Me Too.

Upraded to 12.04 recently. After this upgrade I was left with Kdenlive 0.8.2.1 using KDE development platform 4.8.2 and MLT ver 0.7.7. With this setup I could not render Mpeg-4, Xvid4 , H.264 or flash as they reported unsupported video codec.

I fixed this by
sudo apt-get install libavcodec-extra-53
but then I noted unsupported audio codec: pcm_s16le
But also noted that the Kdenlive web site was recomending Kdenlive 0.9 and MLT 0.7.8 from sunab repository

Which I have now installed. And that brings me to where I am now where I am having exactly the same issues as hamoid and Levan7 [I think Sylvere's issue was a different one].

My videos also appear to be fine too. I also wonder if the MLT is reporting a false abort and error.

//STARTING RENDERING: false , false , "/usr/bin/melt" , "dv_pal_wide" , "avformat" , "-" , "/home/ttguy/Videos/scripts/test_mpg_render.sh.mlt" , "/home/ttguy/Videos/home_movies_vol23a-test.mpg" , () , ("f=mpeg", "acodec=mp2", "ab=384k", "ar=48000", "vcodec=mpeg2video", "minrate=0", "vb=12000k", "bf=2", "b_strategy=1", "trellis=1", "aspect=@16/9", "threads=1", "real_time=-1") , -1 , -1
Started render process: "/usr/bin/melt" "/home/ttguy/Videos/scripts/test_mpg_render.sh.mlt -profile dv_pal_wide -consumer avformat:/home/ttguy/Videos/home_movies_vol23a-test.mpg progress=1 f=mpeg acodec=mp2 ab=384k ar=48000 vcodec=mpeg2video minrate=0 vb=12000k bf=2 b_strategy=1 trellis=1 aspect=@16/9 threads=1 real_time=-1"
"Rendering of /home/ttguy/Videos/home_movies_vol23a-test.mpg aborted, resulting video will probably be corrupted."

So based on inspiration from another thread I tried to run the melt call from the above post in the terminal.

/usr/bin/melt /home/ttguy/Videos/scripts/test_mpg_render.sh.mlt -profile dv_pal_wide -consumer avformat:/home/ttguy/Videos/home_movies_vol23a-test.mpg progress=1 f=mpeg acodec=mp2 ab=384k ar=48000 vcodec=mpeg2video minrate=0 vb=12000k bf=2 b_strategy=1 trellis=1 aspect=@16/9 threads=1 real_time=-1

And it renders the video and eventually returns

[dv @ 0xb5b0c320] Estimating duration from bitrate, this may be inaccurate
[mpeg @ 0xb680adc0] VBV buffer size not set, muxing may fail
Current Frame: 1011, percentage: 99
Segmentation fault (core dumped)

So it appears a real error reported by melt

Today kdenlive updated to 0.9.2

still getting error wile rendering

but i noticed this

for example if i render this file at the end it crashes

hola un saludo a todos mi nombre es fred mi ingles no es bueno no es mi lengua materna estoy tratando de aprender usar Kdenlive y me encontre con este problema y no se como solucionarlo les pido ayuda para solucionar mi problema.

Hola Frederik,

Se trata de un falso aviso de crash, el video de salida existe y esta perfectamente leible en tu /home/fred/kdenlive
Estoy investigantdo por una solucion.

Further on this - when I run the following

/usr/bin/melt /home/ttguy/Videos/scripts/test_mpg_render.sh.mlt -profile dv_pal_wide -consumer avformat:/home/ttguy/Videos/home_movies_vol23a-test.mpg progress=1 f=mpeg acodec=mp2 ab=384k ar=48000 vcodec=mpeg2video minrate=0 vb=12000k bf=2 b_strategy=1 trellis=1 aspect=@16/9 threads=1 real_time=-1

you get various warning messages like ...
"[dv @ 0xb5b0c320] Estimating duration from bitrate, this may be inaccurate
[mpeg @ 0xb680adc0] VBV buffer size not set, muxing may fail"

And then melt goes ahead and starts the processing. Then some time later you get
"
Current Frame: 1011, percentage: 99
Segmentation fault (core dumped)
"
So because the "VBV buffer size not set" warning appears well ahead of the actual crash I suspect it may have nothing to do with this issue.

I was able to extract the following (useless to me) info from the core dump

gdb -c core

Core was generated by `/usr/bin/melt /home/ttguy/Videos/scripts/test_mpg_render.sh.mlt -profile dv_pal'.
Program terminated with signal 11, Segmentation fault.
#0 0x00117d8a in ?? ()

I wonder if this is this bug http://kdenlive.org/mantis/view.php?id=2116#bugnotes

In my opinion the problem is with ffmpeg. On the 22nd of February I wrote about the same problem (rendering crashed at the end but video looks fine):
http://www.kdenlive.org/forum/rendering-crashed-end-just-h264
On the 22nd of February 2012 the problem was only with H.264 profile, and then (in my case) the solution was to downgrade ffmpeg from 0.10 to 0.7.8
From that time there wasn't any signs of fixing the problem (3 months now).

Now ffmpeg 0.7.8 is NOT available in my distribution so I have to use only 0.10.3 (I use Kdenlive 0.9.2, ffmpeg 0.10.3, mlt 0.7.8)
and the error is for the ALL profiles now - see bellow, so apart video crashes at the end of rendering it is IMPOSSIBLE to render any 2pass video now.

HDV
"Rendering of /mnt/video/kdenlive/test.m2t aborted, resulting video will probably be corrupted."

MPEG-2
"Rendering of /mnt/video/kdenlive/test.mpg aborted, resulting video will probably be corrupted."

H.264
"Rendering of /mnt/video/kdenlive/test1.mp4 aborted, resulting video will probably be corrupted."

MPEG-4
"Rendering of /mnt/video/kdenlive/test.mp4 aborted, resulting video will probably be corrupted."

Hopefully there is a new mlt (0.9) and new ffmpeg (0.11) both published few days ago - if those 2 won't solve the problems - we have to ask programers for a fundraising campaign - so finally someone form ffmpeg and mlt team will have some more time to solve those BAD bugs.

Maybe it is A GOOD idea to have in kdenlive error messages with such information, what went wrong in which module, so we will have information where the problem exactly is - in ffmpeg or mlt or kdnlive - so eg. we wont waste the time of kdenlive team if the problem is from melt or ffmpeg...

Please test new packages for Ubuntu Precise with latest mlt update at ppa:sunab/sunab2, the bug seem to be gone ...

If it's all good for everyone I will copy to kdenlive-release ppa.

dist-upgrade is necessary (or partial upgrade in update-manager bad terminology)

"Please test new packages for Ubuntu Precise with latest mlt update at ppa:sunab/sunab2"

As a semi-nube at this sort of thing :-) could you give us some idiot-proof commandline instructurions on how we might try to do this. Thanks.

Slightly Off Topic but why does my ffmpeg report
"This program is not developed anymore and is only provided for compatibility. Use avconv instead (see Changelog for the list of incompatible changes)." but vyalern reports that ffmpeg keeps getting new version numbers.

Thank you, sunab!

After update from: ppa:sunab/sunab2, the problem disappeared. Ubuntu 12.04 (32 bit)...

@ttguy

I was pointing a secondary ppa I use as a sandbox to prepare packages. "ppa:sunab/sunab2" is the "address" of the ppa you can feed in Ubuntu sources manager. If you insist for a command line procedure :

sudo add-apt-repository ppa:sunab/sunab2
sudo apt-get update
sudo apt-get dist-upgrade

@all users the "sunab2" ppa is a sandbox. You are encouraged to DISABLE this ppa immediately. In other occasions packages found here may hurt your system.
If other users confirm success I will push these packages to the stable one (ppa:sunab/kdenlive-release)

thanks sunab for copy/paste solution

at this moment I have both update sources for kdenlive disabled, not to get in troubles with updates.
would you please inform when it is safe to activate sunab kdenlive-release again

other question (as I am editing during next days) where do you want to get feedback

Awesome work sunab. Tested your ppa:sunab/sunab2.
And my test project now renders to completion.

And the command line option reports zero errors:

Hi,

Thanks everyone for your feedback. All glory for this update goes to the mlt developper Dan Dennedy. The release of MLT 0.8.0 adresses a large part of our problem. So it it now pushed to the kdenlive-release ppa.

Now every single pass render works without complaints : tested with Raw DV, Xvid4, Mpeg4, h.264 and webm profiles.
I can confirm the last problem spotted by ttguy : Xvid4 profile with two pass rendering complains... I will investigate more.

This is an occasion for me to remind everyone about mixing as few ppas as possible. Some users asked me so here is the public remimder :

- my packages are built with regular ffmpeg and KDE versions from the original Ubuntu repositories. Don't use backported versions.

- ppa:sunab/kdenlive-release dedicated to the latest kdenlive+mlt stable releases.
- ppa sunab/kdenlive-svn dedicated to the latest development snapshots from kdenlive+mlt : use at your own risks, I've setup this for bug reporting only.

These are my two only ppas dedicated to kdenlive : and most important : NEVER mix them, in a regular basis they become incompatible (different version of libmlt).

Still crashing for me even after just updating, I've tested both 'release' and 'svn' git. Rendering crashes.

Finally the ffmpeg errors have been fixed in git so build script now works again, unfortuneatly rendering still crashes same error with MLT's melt. :-(

*** glibc detected *** /usr/bin/melt: free(): invalid pointer: 0x00007f09e25c4f08 ***

@ yellow : what is the profile used for rendering ?

hi sunab, any of them from Raw DV to h264.

The project I was working on was 10bit 4:2:2 source but assume this is just dithered down by ffmpeg on import, it's certainly picked up as 10bit, plays on the timeline etc.

But even a simple one clip 1080p h264 MOV file crashes rendering trying to encode to h264, xvid, mpeg4, WebM , all exact same error message, so it's not related to 10bit.

Ubuntu x64 12.04

**EDIT**

Can also confirm exact same error on another machine x64 Ubuntu 12.04 latest sunab svn build from today. Two more machines to go. 32bit OS on them though.

**EDIT**

32bit 12.04 Ubuntu + sunab kdenlive- svn renders to certin formats like mpeg2 but complains x264 and dv are missing.:-( No crashing though. :-) haven't used the build script on 32bit.

**EDIT**

Updated again today, melt wouldn't update though, listed in the Update Manager but unticked and uninstallable because it clashed with kdenlive data, so uninstalled kdenlive, MLT etc everything related and tried reinstalling now kdenlive-svn won't install at all due to dependancy problems:

The following packages have unmet dependencies.
kdenlive : Depends: kdenlive-data (= 0.9.2+git20120605.7faa38b6-0ubuntu0~sunab~precise1) but it is not going to be installed
Depends: melt but it is not going to be installed

So built from the build script and rendering still crashes even after further updates relating to ffmpeg git and kdenlive git. Same melt error.

Another freaking mess relating to rendering, reminisent of last months or two's troubles. x64 related though I think as 32bit renders except only certain codecs, x264 not being one of them.

@ yellow

The problem with the ppa is very common, at the moment you updated your package list the mlt/kdenlive packages were "half built". Tipically, the *-data packages are arch idenpendant but built in a i386 virual machine. These days Soyuz (the ppa build system) is very busy, as a result packages for i386 and amd64 are built with hours of delay, in the mean time all people updating packages from the ppa face dependencies errors. If you wan't to avoid this, check first on the lanchpad page if all packages are built.

Now for the rendering problem :

you said :"any of them from Raw DV to h264". I've experienced the same behaviour with Kdenlive 0.9 + MLT 0.7.8 (in the kdenlive-release ppa). Now I've pushed to this ppa MLT 0.8.0 and rebuilt kdenlive 0.9.2 and now the this problem is gone.(execpt with xvid4 profile with two pass rendering)

Note : the kdenlive-svn ppa wasn't up to date this past week. Yesterday I pushed new packages so you can expect crash free rendering for most profiles too.

By the way, I hope you don't use a backported ffmpeg version.

sunab first of all thank you for continuing to provide your PPAs I really appreciate the ability to use either of them.

Thanks for the explainations and finally no I never use backports.

Will try again and kind regards.

**EDIT**

No better, still crashing rendering on either the 'release' build or the 'svn' with x64 12.04 Ubuntu machines.

Yellow, could you upload a render script of your project to be able to check the render settings ?

Hi yellow & sunab,

This is most strange. I'm using x64 ubuntu and all rendering is fine except xvid which is 1 pass only.

I'm using:-

Kdenlive 0.9+git20120529....
Mlt 0.8+git20120604....

ffmpeg compiled from git about 10 days ago (the latest update.)

Haven't updated Kdenlive etc today. Too scared.

hi normcross,

I am unable to reproduce the yellow's last problem.

All is ok for me too except xvid 2 pass rendering like you.

Don't be scared ;)

I carefully remind everyone here that my packages are built against regular ubuntu ffmeg/libav packages. Using my packages with manually built ffmpeg/libav will work until a git change break binary compatibility. So it's risky...

Hi, I just built from source using the build script. To my knowledge this is completely self contained and that everything kdenlive needs to use and successfully render is contained within the dated folder. No access to system wide libav or whatever else. if this is incorrect then maybe that's the problem, but it's a problem I have on more than one PC.

This is the latest failed render error, any codec, x264, mpeg2, libxvid shows as unsupported as sunab mentions.

ERROR: ld.so: object '/lib/i386-linux-gnu/libpthread.so.0' from LD_PRELOAD cannot be preloaded: ignored.
*** glibc detected *** /home/yellow/kdenlive/20120606/bin/melt: free(): invalid pointer: 0x00007ffff7987f08 ***

The libpthread is a new addition to the error message which previously was just the melt error free(): invalid pointer.....

With regard to PPA builds and system ffmpeg/libav, all these libraries are Ubuntu distro's own 4:0.8.1ubuntu1

I just updated and rendered out a small selected zone with Mpeg4 and H.264 both 2 pass and all works fine here.

@yellow : sorry to see the problems you're having there.

normcross, thanks for your comment. :-)

Funny I just tried rendering just a selection following your comment and kdenlive from PPA just crashes outright with a segfault. :-( where as whole project just gives render error.

**EDIT**

Rendering a selection on the build script version doesn't segfault, just crashes rendering.

This is very wierd, something is messed up on your system(s).

The lastest git with build script and with my packages should be working. They are working here and for other users. I've just tested both methods in fresh installed virtual machines, and I'am unable to reproduce the crash.

With the build script the produced binaries are self contained in a forlder but all these binaries may be affected by various system wide dependencies, as the build script doesn't provide latest git for all dependencies.

edit : could you upload a render script of your project to be able to check the render settings ?

hi sunab

#! /bin/sh

Just a simple 1 clip file crashes even.

I'd add that with regards to messed up system(s), I've been happily rendering projects on all machines right up until upgrading to 12.04 from 11.10 and recent kdenlive / MLT development.

I've also just wiped all traces of libav libraries, kdenlive and MLT and reinstalled them all again, still no good. :-(

could you share customprofile1 content?

sorry, here it is:

description=HD 1080p DSLR 25 fps
frame_rate_num=25
frame_rate_den=1
width=1920
height=1080
progressive=1
sample_aspect_num=1
sample_aspect_den=1
display_aspect_num=16
display_aspect_den=9
colorspace=601

Crashes happen any profile, even kdenlive own.

thanks

Hi yellow,

When you say "upgrading to 12.04" was that really an upgrade or a fresh install?

I've had so much trouble with upgrades in the past (well... twice actually) that I now do a fresh install every time.
