928	Wrong picture marking information usage in derivation of motion vector components	mcoban		"In HM during the motion information derivation process, wrong picture marking information is for collocated partition's reference frame. HM uses collocated partition's current picture marking  information (short term or long term) instead of its picture marking information at the time of its usage as a reference frame as specified in section 8.5.3.1 of the latest specification draft. The issue shows up when TMVP is enabled with long term reference pictures. Attached patch addresses this problem.

In High Efficiency Video Coding (HEVC) text specification draft 9 section 8.5.3.1
  
8.5.3.1	Derivation process for motion vector components and reference indices
...
The function LongTermRefPic( nPic, nPb, refIdx, LX ), with X being either 0 or 1, is defined as follows. If the picture with index refIdx from reference picture list LX of the slice containing prediction block nPb in the picture nPic was marked as ""used for long term reference"" at the time when nPic was the current picture, LongTermRefPic( nPic, nPb, refIdx, LX ) is equal to 1; otherwise LongTermRefPic( nPic, nPb, refIdx, LX ) is equal to 0.
