Turns out MLT and MELT version 7.7 were the problem.

I used Synaptic package manager to force MLT and MELT to version 7.6 and I am able to render.

I also switched to the Kdenlive release PPA for the time being.

So I'm able to render with Kdenlive and MLT 7.6.

i can confirm this issue

UBuntu 11.10
with kdenlive from
it crashes immediately on render (any format with the most trivial project)

with kdenlive from
it renders ok

The svn only started crashing in the last couple of days (Admittedly I switched machines and used 64bit instead of 32bit..so this is not 100% clear)..both machine have identical SW stack otherwise

None of the above fix my "rendering crashed" issue. Tried them all.
So, kdenlive is currently completely useless for me.

I'm on fresh install of Mint 12 64bit.

I can confirm that a very recent change in MLT breaks xml output and thus breaks rendering. I just sent more infos on MLT's mailing list, issue should hopefully be fixed soon

Same here, rendering crashed issue in any ouput format. Waiting for this MLT bug fix...

My kdenlive and melt got updated by update manager yesterday.

Now when i open a previous project, it stops loading at 75% and the whole application freezes and has to be killed to get rid of. As a bonus it corrupts the video project file.

As well, if i make a new project from scratch and press "render to file", the application freezes immediately and must be killed.

This is from http://ppa.launchpad.net/sunab/kdenlive-svn/ubuntu [^]

Can you please tell me which MLT version you are using? Latest version from sunab experimental repository is supposed to fix these problems (mlt 0.7.7+git20120201.7f33e92c).

I didn't notice mlt got updated yesterday. I had version 29.01 prior to upgrading, I ran:

sudo apt-get update

then went to synaptics and marked melt for upgrading to the version you pointed out (20120102). Upgraded fine but KDEnlive still crashes upon rendering :-/

edit: added an 'r'

Then I need some more infos. Can you paste your MLT, Kdenlive anf FFmpeg versions:

dpkg -l libmlt* | grep ^ii
dpkg -l kdenlive* | grep ^ii
dpkg -l libavformat* | grep ^ii
dpkg -l ffmpeg* | grep ^ii

And when you say Kdenlive crashes on rendering, does the Kdenlive application really crash or is it just the rendering that fails?

Sorry, I meant that the rendering fails with the same error as stated by others above.
Sorry for the mess below, try to compress that in fewer lines that it takes...

edit: okay, I see some packages were not automatically updated as dependencies by synaptics, gonna do that now...
eidt 2: mlt, melt, what is what? im a bit confused now ...

You should probably also update your MLT version to sunab's latest version. One strange thing is your ffmpeg version.

Ubuntu Oneiric official ffmpeg packages are at version 0.7.3:

http://packages.ubuntu.com/search?keywords=libavformat&searchon=names&suite=oneiric&section=all [^]

But looks like you have an older version. That might well be the reason for the rendering failure...

I'm gonna look into this. I've tried to keep my system as stable as possible by not running ubuntu updates lately but it looks like it's not gonna happen. thanks for your time and help!

edit: mlt was the issue, not ffmpeg, finally rendering! cheers!

works pefectly for me again with:

ii libavformat53 4:0.7.3-0ubuntu0.11.10.1 Libav file format library

@karsta62 looks like your sunab git packages are about a week older than mine...this was fixed in mlt in the last week.

Thanks oschonrock.
I had the kdenlive-release repository active. I have been switching between those two desperately waiting for a fix. I changed it to kdenlive-svn now, got the updates and the rendering finally is in progress.

Eventually the rendering crashed in the end. But the resulting video file was ok. Good enough for me.
