Field Documentation

◆ buffer_removal_delay_length

uint8_t Dav1dSequenceHeader::buffer_removal_delay_length

◆ cdef

uint8_t Dav1dSequenceHeader::cdef

◆ chr

enum Dav1dChromaSamplePosition Dav1dSequenceHeader::chr

chroma sample position (av1)

◆ color_description_present

uint8_t Dav1dSequenceHeader::color_description_present

◆ color_range

uint8_t Dav1dSequenceHeader::color_range

Pixel data uses JPEG pixel range ([0,255] for 8bits) instead of MPEG pixel range ([16,235] for 8bits luma, [16,240] for 8bits chroma).

◆ decoder_model_info_present

uint8_t Dav1dSequenceHeader::decoder_model_info_present

◆ delta_frame_id_n_bits

uint8_t Dav1dSequenceHeader::delta_frame_id_n_bits

◆ display_model_info_present

uint8_t Dav1dSequenceHeader::display_model_info_present

◆ dual_filter

uint8_t Dav1dSequenceHeader::dual_filter

◆ encoder_decoder_buffer_delay_length

uint8_t Dav1dSequenceHeader::encoder_decoder_buffer_delay_length

◆ equal_picture_interval

uint8_t Dav1dSequenceHeader::equal_picture_interval

◆ film_grain_present

uint8_t Dav1dSequenceHeader::film_grain_present

◆ filter_intra

uint8_t Dav1dSequenceHeader::filter_intra

◆ force_integer_mv

enum Dav1dAdaptiveBoolean Dav1dSequenceHeader::force_integer_mv

◆ frame_id_n_bits

◆ frame_id_numbers_present

uint8_t Dav1dSequenceHeader::frame_id_numbers_present

◆ frame_presentation_delay_length

uint8_t Dav1dSequenceHeader::frame_presentation_delay_length

◆ hbd

uint8_t Dav1dSequenceHeader::hbd

0, 1 and 2 mean 8, 10 or 12 bits/component, respectively. This is not exactly the same as 'hbd' from the spec; the spec's hbd distinguishes between 8 (0) and 10-12 (1) bits/component, and another element (twelve_bit) to distinguish between 10 and 12 bits/component. To get the spec's hbd, use !!our_hbd, and to get twelve_bit, use hbd == 2.

◆ height_n_bits

uint8_t Dav1dSequenceHeader::height_n_bits

◆ inter_intra

uint8_t Dav1dSequenceHeader::inter_intra

◆ intra_edge_filter

uint8_t Dav1dSequenceHeader::intra_edge_filter

◆ layout

enum Dav1dPixelLayout Dav1dSequenceHeader::layout

format of the picture

◆ masked_compound

uint8_t Dav1dSequenceHeader::masked_compound

◆ max_height

int Dav1dSequenceHeader::max_height

◆ max_width

int Dav1dSequenceHeader::max_width

Maximum dimensions for this stream. In non-scalable streams, these are often the actual dimensions of the stream, although that is not a normative requirement.

◆ monochrome

◆ profile

uint8_t Dav1dSequenceHeader::profile

Stream profile, 0 for 8-10 bits/component 4:2:0 or monochrome; 1 for 8-10 bits/component 4:4:4; 2 for 4:2:2 at any bits/component, or 12 bits/component at any chroma subsampling.
