Intel MSDK MPEG 2 Decoder Problem

[HT]

Hi

Built gstreamer 1.12 (Base, Good, Bad, etc.) from source and ported 
gstmsdkmpeg2dec.c from master branch to be able to decode mpeg2. It 
builds fine; however, there are noticeable visual artifacts at bottom 
right of the decoded video. Just wondering if this  is a known issue 
(hopefully with a solution)?

CLI:

gst-launch-1.0  udpsrc name=udpsrc uri=udp://localhost:9000 sync=TRUE 
do-timestamp=true caps="video/mpegts, systemstream=(boolean)true, 
packetsize=(int)188" ! \
         queue name=qtsparse ! tsparse name=tsparse set-timestamps=true  ! \
         queue name=qtsdemux ! tsdemux name=tsdemux emit-stats=false 
parse-private-sections=true !  \
         queue name=qvideoparse ! mpegvideoparse name=mpegvideoparse 
gop-split=true ! \
         queue name=qdec ! msdkmpeg2dec name=dec  ! \
         filesink location=cap.raw

Cheers,
