#854 closed enhancement (wontfix)

Multi-slice QP setting in one frame is not supported by HM9.0

Reported by: xx.cai Owned by:
Priority: minor Milestone:
Component: HM Version: HM-9.0
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…


In TAppEncCfg.cpp:

if ( m_pchdQPFile )


FILE* fpt=fopen( m_pchdQPFile, "r" );
if ( fpt )

Int iValue;
Int iPOC = 0;
while ( iPOC < m_iFrameToBeEncoded )

if ( fscanf(fpt, "%d", &iValue ) == EOF ) break;
m_aidQP[ iPOC ] = iValue;




The current HM can only load one QP for the whole frame. Multi-slice in one frame coding with different QP is not available.

Please provide code if you are requesting the feature. Otherwise I don't see how we would be able to add this.

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

I don't see a strong need to specify multiple QPs per picture in an example encoder. Also, no patch has been provided.

Thus I'm closing this as "won't fix".
