$\lambda=qpFactor \times 2^{qp+6*(bitDepthLuma-8)-12}$,
where $qp$ is the slice QP and $qpFactor$ is calculated as follows:

\begin{tabular}{lp{0.45\textwidth}}

%% In-loop filtering parameters

\begin{OptionTableNoShorthand}{In-loop filtering parameters}{tab:inloop-filter}
\Option{LoopFilterDisable} &
%\ShortOption{\None} &
\Default{false} &
Enables or disables the in-loop deblocking filter.
\\

\Option{LFCrossSliceBoundaryFlag} &
%\ShortOption{\None} &
\Default{true} &
Enables or disables the use of in-loop filtering across slice
boundaries.
\\

\Option{LoopFilterOffsetInPPS}&
%\ShortOption{\None}&
\Default{false}&
If enabled, the in-loop deblocking filter control parameters are sent in PPS. 
Otherwise, the in-loop deblocking filter control parameters are sent in the slice segment header.
If deblocking filter parameters are sent in PPS, the same values of deblocking filter parameters 
are used for all pictures in the sequence (i.e. deblocking parameter = base parameter value).  
If deblocking filter parameters are sent in the slice segment header, varying deblocking filter 
parameters can be specified by setting parameters tcOffsetDiv2 and betaOffsetDiv2 in the GOP structure table. 
In this case, the final value of the deblocking filter parameter sent for a certain GOP picture is equal to 
(base parameter + GOP parameter for this picture). Intra-pictures use the base parameters values.
\\

\Option{LoopFilterTcOffset_div2}&
%\ShortOption{\None}&
\Default{0}&

shall be an integer number in the range $-6..6$.
\\

\Option{LoopFilterBetaOffset_div2}&
%\ShortOption{\None}&
\Default{0}&
Specifies the base value for the in-loop deblocking filter parameter beta_offset_div2. The final value of beta_offset_div2 
shall be an integer number in the range $-6..6$.
\\

\Option{DeblockingFilterMetric}&
%\ShortOption{\None}&
\Default{0}&
Specifies the use of a deblocking filter metric to evaluate the suitability of deblocking. If non-zero then
LoopFilterOffsetInPPS and LoopFilterDisable must be 0. Currently excepted values are 0, 1 and 2.
\\

\Option{LFCrossSliceBoundaryFlag}&

\\

\Option{NumHorVirtualBoundaries}&
%\ShortOption{\None}&
\Default{0}&
Specifies the number of horizontal virtual boundaries. The value of NumHorVirtualBoundaries shall be in the range of 0 to 3, inclusive.
\\

\Option{VirtualBoundariesPosX}&
%\ShortOption{\None}&
\Default{\NotSet}&
Specifies the locations of the vertical virtual boundaries in units of luma samples
