Installed ffmpeg in 64 bit 12.04 and got this message in terminal:
This program is only provided for compatibility and will be removed in a future release. Please use avconv instead.
What is best to do? I've only used ffmpeg in the past and am familiar with it.

Is avconv as easy to use as ffmpeg?
Should I remove ffmpeg and go with avconv?
Do you use similar code as ffmpeg, or is avconv code completely different?
