It seems that the picture loss detection is trying to conceal a picture that has not been lost, right? Or did you actually loose a picture?

I think it may be caused by the calculation of POC.
At the decoder side, the POC of IDR picture is set to be 0.
In Void TDecCavlc::parseSliceHeader()
if(rpcSlice->getNalUnitType()==NAL_UNIT_CODED_SLICE_IDR)
{
...
rpcSlice->setPOC(0);
...
}

But it seems that the encoder does not do that.

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

Closed as duplicate of #271.
A fix for picture loss has been provided in to HM-5.0-dev-bugfix r1719 (see ticket #271). A fix for deblocking filter with lost pictures has been provided in r1720 (see ticket #272)
