Bug in edge based prediction for low complexity

Reported by: virginie.drugeon@… Owned by: fbossen
Priority: minor Milestone:
Component: HM Version:
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…

Description

Edge based complexity is currently never used in the low complexity configuration.

The following bug fix solves the problem:
In the file TComEdgeBased.cpp, the function TComEdgeBased::shift_right_round should be:

inline int TComEdgeBased::shift_right_round(int val, int b)
{

if(b <= 0)

return val;

else

return (val + (1 << (b-1))) >> b;

}
