Problem with GStreamer element ffdeinterlace in Arista (ubuntu 14.04)

[sergiobenrocha2]

There is a problem that I'm not sure if it's Arista or other related package (like something with Python).

Trying to convert a video from .ogv to webm, and i got a message like:

Required plugin could not be found
Python (v2.7) requires to install plugins to support the following multimedia feature: GStreamer element ffdeinterlace

Installed ubuntu-restricted-extras and others gstreamer related, but it does not work.

same problem

I use this and it try to work as usual but it gets frozen:
sudo add-apt-repository ppa:mc3man/trusty-media
sudo apt-get update
sudo apt-get install ffmpeg gstreamer0.10-ffmpeg

I have just had partial success. I am using a Dell N5110 with Ubuntu 14.10

I first went to synaptic and installed libavcodec56

The specific code that worked on the commandline only was:
arista-transcode out.ogv out.webm
where out.gov was the file to be converted.

The overall quality is good though it took several minutes to convert this 82 second file.

The arista gui still does not work. Have no clue why.

I should mention that it produces two files. One is called out-computer1.webm which has no sound while the other called out-computer.web has 25fps video and sound. The 5.8MB .ogv file got converted into a 2.4 Mb .webm file.

Same problem on Ubuntu 16.04, the Ehjaime solution (with ppa) doesn't run. I can't convert anything... I use handbrake, but for me arista is easier to use pity it's no more in the ubuntu 16.04 repositories.
