Struct Mpeg2SequenceHeader 

pub struct Mpeg2SequenceHeader {
    pub horizontal_size: u32,
    pub vertical_size: u32,
    pub aspect_ratio_information: u8,
    pub frame_rate_code: u8,

}

Sequence header (§6.2.2).

Fields

horizontal_size: u32

vertical_size: u32

aspect_ratio_information: u8

frame_rate_code: u8

bit_rate: u32

vbv_buffer_size: u32

constrained_parameters_flag: bool

intra_quantiser_matrix: Option<[u8; 64]>

Present only if load_intra_quantizer_matrix=1. The matrix is given in zig-zag scan order — use zigzag_to_raster_quant before submitting to the HW backend.

non_intra_quantiser_matrix: Option<[u8; 64]>

Same shape as intra_quantiser_matrix.

Implementations

impl Mpeg2SequenceHeader

pub fn intra_quantizer_matrix_raster(&self) -> [u8; 64]

Effective intra-quantizer matrix in raster scan order (the custom matrix if present, otherwise the spec default).

pub fn non_intra_quantizer_matrix_raster(&self) -> [u8; 64]

Effective non-intra-quantizer matrix in raster scan order.
