FFmpeg mux of separate audio and video files causes audio quality degradation.

Steps to reproduce

Steps to reproduce:
1. In the admin UI select"upload recording"
2. On Upload recording page select multiple files and up load a video with no audio track and a separate audio.
3. Submit for processing.

Actual Results:
profile.mux-av.work.ffmpeg.command muxes the file to a low bit rate working file.

Expected Results:
profile.mux-av.work.ffmpeg.command muxes the video with no significant loss of quality.

Workaround (if any):
Edit :
$FELIX_HOME/conf/encoding/matterhorn-movies.properties

Replacing:
profile.mux-av.work.ffmpeg.command = -i #{in.audio.path} -i #{in.video.path} -sameq -shortest -strict unofficial #{out.dir}/#{out.name}#{out.suffix}

[Updated] With:
profile.mux-av.work.ffmpeg.command = -strict unofficial -i #{in.video.path} -i #{in.audio.path} -sameq -shortest -acodec copy #{out.dir}/#{out.name}#{out.suffix}
