Arista/Transcoder does not work with Fluendo CODEC pack installed

[pmlopes]

If I install the fluendo codec pack to better playback support, when trying to convert a video say from my HD camera to some other format to share with my family, there is a crash while trying to decode the original width/height and video caps.

I have no experience with gstreamer and after digging on the internet i found this site with and example of code that correctly extracts the width and height:

I also raised a question with fluendo about the metadata but up to now i have now answer yet.

Interesting. I'm actually using the python version of the discoverer. Can you run with arista-gtk -v and paste in any output of the errors?

I've contacted fluendo and they claim that this might work on ubuntu 12.10 and that they will also have a look into the current LTS 12.04.2.

I am planning to try out the 12.10 tomorrow and will post what i can find.

I've installed 12.10 and I get the same error:
