pub fn parse_split_cu_flag(
state: &mut HevcSliceCabacState<'_>,
depth: u8,
_left_available: bool,
_above_available: bool,
) -> boolExpand description
Read split_cu_flag from the bitstream.
Context index is derived from the current depth plus the availability of
left/above neighbours (simplified: ctx_idx = depth.min(2)).
