Changeset 118 in SHVCSoftware for branches/HM-10.0-dev-SHM/source/Lib/TLibCommon

Message:

Signaling direct reference layers in VPS extension (MACRO: VPS_EXTN_DIRECT_REF_LAYERS)

Includes signaling of direct_dependency_flag in VPS extension, that indicates the direct reference layers of all the layers. Includes configuration file support using NumDirectRefLayers%d and RefLayerIds%d. Arbitrary values of nuh_layer_id for different layers would still need configuration file support for layer_id_in_nuh.
