#1328 closed defect (fixed)

Encoder: Decoding unit info encoding may fail and is only available for SliceMode=1

Reported by: ksuehring Owned by: ksuehring
Priority: minor Milestone: HM-16.4
Component: HM Version: HM-16.0
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…

Description

Decoding units information is only generated for SliceMode=1.

Other Slice modes (and dependent slice segment modes) are also interesting use cases.

The encoder may also crash in other slice modes (or slices disabled) when picture timing SEI is enabled and SliceArgument is too small due to a division by zero.

Also, when using the SliceArgument parameter for calculating the number of DUs, it is still scaled by the CTU depth (which is probably the last remaining piece of fine granular slices).
