Description

Dear

I am a PH.D of Tongji university of China. Now I am researching the Parallelism of HEVC in TOKUSHIMA university.

You know that the parallel base the HM-12.0 test model is very low.So this is my interest point.

But now i met a problem. In the HM-12.0 test model, the function --- Void TEncCu::xCompressCU( TComDataCU*& rpcBestCU, TComDataCU*& rpcTempCU, UInt uiDepth, PartSize eParentPartSize ), is a recursive call, which is to compress a CU block recursively with enabling sub-LCU-level delta QP. I don't know how to make this function a non-recursive function.

If you give me some advise , i will thank you very much.

Best wish

jimmy

  • Resolution set to invalid
  • Status changed from new to closed

Modifying the HM to enable parallel computation is not a trivial task. Delta QP is not one of the first problems i would consider. Instead, i would disable/ignore it (it does not form part of the common test conditions) and reconsider it later when the more significant issues are resolved.
