Members

MaxL0ReferencesForP

The maximum value allowed in the slice headers for (num_ref_idx_l0_active_minus1 +1) when encoding P frames. This is equivalent to the maximum size of an L0 for a P frame supported.

MaxL0ReferencesForB

The maximum value allowed in the slice headers for (num_ref_idx_l0_active_minus1 +1) when encoding B frames. This is equivalent to the maximum size of an L0 for a B frame supported.

MaxL1ReferencesForB

The maximum value allowed in the slice headers for (num_ref_idx_l1_active_minus1 +1) when encoding B frames. This is equivalent to the maximum size of an L1 for a B frame supported.

MaxLongTermReferences

The maximum number of references used in a frame that can be marked as long term reference.

MaxDPBCapacity

The maximum number of unique pictures that can be used from the DPB the caller manages (number of unique indices in L0 union L1) for a given EncodeFrame command on the underlying hardware.
