Signalling of syntax element all_layers_idr_aligned_flag in VPS VUI

Reported by: fhendry Owned by: Vadim
Priority: minor Milestone: SHM-8.0
Component: SHM software Version: SHM-6.1
Keywords: Cc: Vadim, jct-vc@…

Description

The signalling of all_layers_idr_aligned_flag is different from the spec and may cause a bug.

When the following situation happen, the signalling is different from what is expected according to the spec:

  • vps_vui_present_flag is equal to 1
  • cross_layer_pic_type_aligned_flag is equal to 1

In such case, the cross_layer_irap_aligned_flag is not signalled but its value is inferred to be 1 (i.e., equal to vps_vui_present_flag) and the syntax element all_layers_idr_aligned_flag must be signalled.

However, with the current implementation, syntax element all_layers_idr_aligned_flag would not be signalled.

Patch to fix this is attached.
