Derivation of intra luma mode predictors when neighbor is PCM coded.

Component: HM Version: HM-6.2
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…

Description

In TComDataCU::getIntraDirLumaPredictor, the logic used to determine iLeftIntraDir and iAboveIntraDir directions should take into account the case where one of the neighboring CUs is PCM coded.

The values in m_puhLumaIntraDir should either be initialized to "Intra_DC" rather than "2" (which no longer corresponds to DC mode), and/or there should be additional cases added to getIntraDirLumaPredictor( ) to check for PCM mode.

It is likely that the Intra_DC initialization is a simple solution. Attachment is a patch for HM-6.0-dev (rev. 2090). It is recommended that the patch is applied to the HM-6.0-dev branch.
