#190 closed defect (fixed)

Intra reference sample padding removes some frame-boundary samples

Reported by: vwahadaniah Owned by:
Priority: minor Milestone:
Component: HM Version: HM-3.3
Keywords: intra, padding, availability Cc: fbossen, ksuehring, davidf, jct-vc@…

Description

When constrained intra prediction is disabled, the codes to check the availability of intra reference samples at above-right and below-left locations do not take care of frame boundary. When above-right and/or below-left neighboring blocks are partially available within the frame, their available samples are removed and padded with the last samples from above and/or left neighbors respectively. This bug was identified in HM-3.0 and is still present in HM-3.3 (rev 1106).
