Tvheadend

Hi all,

I have installed the Intel Media SDK in ubuntu 14.04 following the steps from https://ffmpeg.org/pipermail/ffmpeg-user/2015-October/028761.html and it was done apparentely without issues. However, after install tvheadend with libmfx option enabled, etc, I see the transcoding option to h264_qsv, but selecting this I only got audio and tvheadend show the following in the log:

I have seen some posts with different information, but no idea what could be wrong in my setup.

Current configuration:
TVH Build: 4.1-1183~g637d1f3 (2015-12-07T21:39:49+0100)
Media SDK:2015 r6
Linux kernel:3.14.5
ffmpeg: 2.8.3

I would really appreciate any light on this

Thanks!
