Thank you Karsten for providing the patch. I think it looks fine.

I added a new version of it with two minor changes:

added #if G1002_RPS around
, m_numReorderFrames ( 0)
in TComSlice.cpp to avoid crash when G1002_RPS is 0

and changed so that MaxNumberOfReorderPictures equal to -1 indicates that m_numReorderFrames shall be set to the optimal value. This way also MaxNumberOfReorderPictures equal to 0 can be explicitly tested.

  • Resolution set to fixed
  • Status changed from assigned to closed

I have applied the patch in r1764 (HM-5.0-dev-misc) with one minor change: The configuration output text has been changed to state that -1 means automatic selection.
