The version you propose is too old for new features of Serviio v1.0.1
Here is the version which is in the repository:
FFmpeg version 0.6.1, Copyright (c) 2000-2010 the FFmpeg developers
built on Jan 16 2011 23:30:21 with gcc 4.2.1 20070719 [FreeBSD]
This version does not support some of the new options that are used by new version of Serviio.
On the ffmpeg.org, the newest public version is 0.11.1.
