Arista Transcoder Not Working

Question

In previous versions of Ubuntu, I was installing and using Arista Transcoder seamlessly with no problems at all. After upgrading to Ubuntu 14.04 and installing Arista, whenever I try to transcode any video, the following error message appears

Python2.7-minimal requires an additional plugin for this operation.
The following plugin is required:
GStreamer element ffdeinterlance
Do you want to search for this now?

When I press "Search", the following error message appears:

Cannot add conversion to queue because of missing elements!

Any idea how to solve this problem?

Answer 1

You are missing the package gstreamer0.10-ffmpeg. It is, however, not available in the 14.04 repositories, so you can get it from a PPA:

sudo add-apt-repository ppa:mc3man/trusty-media
sudo apt-get update
sudo apt-get install gstreamer0.10-ffmpeg
