from email report (Uday Krishna G):

While decoding a single frame using HM-6.0rc1 Decoder, it shows error message: "failed to write reconstructed YUV file", but working fine for multiple frames.

In case of IDR frame decoding, for single frame it is trying flush output before opening the recon file. So it fails to write the data to recon YUV.

Code in HM-5.1

In file TAppDecTop.cpp, in decode( ) function, the following condition

                     if(nalu.m_UnitType == NAL_UNIT_CODED_SLICE_IDR ) {
                            xFlushOutput( pcListPic );
                      }

i changed code as follows,

                    if(nalu.m_UnitType == NAL_UNIT_CODED_SLICE_IDR  && !(uiPOC == 0)) {
                            xFlushOutput( pcListPic );
                      }

then it is working fine.

Is this change correct or any other solution?
