Unknown encoder 'libfaac'

[samaresh]

I can't convert video in Winff. It says Unknown encoder 'libfaac'. This problem happened after update libavcode.I had already Medibuntu Repository added and libavcode-extra-53 installed.
The output of ffmpeg -formats | grep aac was

ffmpeg version 0.8.3-4:0.8.3-0ubuntu0.12.04.1, Copyright (c) 2000-2012 the Libav developers

Please help.

In short libfaac has been removed from FFmpeg for licensing reasons. So instead of using the following option to encode AAC:
-acodec libfaac
Use FFmpeg's experimental encoder instead:
-acodec aac -strict experimental

Ubuntu has updated its version of libavcode-extra-53; therefore its version number has surpassed what is available from Medibuntu. Either wait for Medibuntu to update its version, or you can go back to what is currently available from Medibuntu. See this post for one method of doing this.
