Greetings!

I was excited about the newest version release, but I can't make it work! I have the following configuration:

· Ubuntu 12.04
· Kdenlive 0.9.2-0ubuntu0~sunab~precise2
· MLT version 0.8.0

Config Wizard says that it's all well!

When I add a .mp3 clip I get this error:

kdenlive: symbol lookup error: kdenlive: undefined symbol: _ZN3Mlt5Frame12get_positionEv

When I add a .mp4 clip I get this error:
kdenlive: symbol lookup error: kdenlive: undefined symbol: _ZN3Mlt5Frame12get_positionEv

When I add an image file it works well!

From http://www.kdenlive.org/user-manual/downloading-and-installing-kdenlive/pre-compiled-packages/ubuntu-packages it says that:
>> The recommended version of Kdenlive is 0.9 and MLT 0.7.8 <<
I tried, but can't downgrade MLT from 0.8.0 to 0.7.8 - should I?

Any advice on how to proceed?

Thank you!

This is what I get in a terminal (bearing in mind I am using a later version than you):-

You seem to have mixed versions of mlt installed. If that was me, I would just remove kdenlive and all of that lot, update and reinstall.

But that's just me. :-)

It's solved!

I've reinstalled kdenlive and melt few times before, but this time I've deleted all the old versions of /usr/lib/libmlt*

Now it works well... for the "Add Clip" part. Will test later to see the effects and the rendering.

Thanks!
