FFMPEG Error while Attempting TrueHD Transcoding

I am trying to transcode a mkv file (H.264 video, TrueHD audio) using the Sony 2010 profile which is trying to transcode the audio to ac3. I keep getting an error which kills ffmpeg and keeps the file from transcoding. Ffmpeg seems to be working fine on everything except the TrueHD files. The error is as follows:

  Code:

I am using ffmpeg version 2.1.8 compiled by barmalej2 and Serviio version 1.5.2 .
Does anyone know what this error means and what I need to look at in order to fix it? Any help would be greatly appreciated.
