Hi,

Sorry for my english.

Searching on forum, I found this topic: http://www.kdenlive.org/forum/solved-kdenlive-rendering-crashed

It relates the problem of mlt with aac sound support. I remembered I had already solved problems like this in Ubuntu with the command padsp, which emulates the dsp device (since it no longer exists on Ubuntu).

So I test in Kdenlive, and it worked!

I used this command: padsp kdenlive

Proxy still chrashes. Didn't try rendering...

What version of Kdenlive are you using? If it is 0.9, the version on the repository really chrashes. Try to build the source.

I'm using the version from ubuntu 12.04 repositories. Waiting for sunab's version :)

@KoRnholio8

Kdenlive 0.9 release changelog extract :
Fix crash on proxy creation (concurrency issue) (http://kdenlive.org/mantis/view.php?id=2471)

12.04 builds are ready.

Thanks for your feedback.

I've upgraded to 0.9, but proxy returs the following message:

@ KoRnholio8:

You need to install the mp3 codec, install package:

libmp3lame0

@j-b-m: already installed - tried reinstalling, still the same error.

OK, proxy working - had to install ubuntu-restricted-extras.

Thanks j-b-m and sunab!

Kdenlive on my computer only works if I launch with padsp. Anyone know why?
