## Field Documentation

## ◆ all_layers

int Dav1dSettings::all_layers

output all spatial layers of a scalable AV1 biststream (default 1)

## ◆ allocator

Dav1dPicAllocator Dav1dSettings::allocator

Picture allocator callback.

## ◆ apply_grain

int Dav1dSettings::apply_grain

whether to apply film grain on output frames (default 1)

## ◆ decode_frame_type

enum Dav1dDecodeFrameType Dav1dSettings::decode_frame_type

frame types to decode (default DAV1D_DECODEFRAMETYPE_ALL)

## ◆ frame_size_limit

unsigned Dav1dSettings::frame_size_limit

maximum frame size, in pixels (0 = unlimited, default 0)

## ◆ inloop_filters

enum Dav1dInloopFilterType Dav1dSettings::inloop_filters

postfilters to enable during decoding (default DAV1D_INLOOPFILTER_ALL)

## ◆ logger

Dav1dLogger Dav1dSettings::logger

Logger callback.

## ◆ max_frame_delay

int Dav1dSettings::max_frame_delay

Set to 1 for low-latency decoding (0 = ceil(sqrt(n_threads)), default 0)

## ◆ n_threads

int Dav1dSettings::n_threads

number of threads (0 = number of logical cores in host system, default 0)

## ◆ operating_point

int Dav1dSettings::operating_point

select an operating point for scalable AV1 bitstreams (0 - 31, default 0)

## ◆ output_invisible_frames

int Dav1dSettings::output_invisible_frames

output invisibly coded frames (in coding order) in addition to all visible frames. Because of show-existing-frame, this means some frames may appear twice (once when coded, once when shown, default 0)

## ◆ reserved

uint8_t Dav1dSettings::reserved[16]

reserved for future use

## ◆ strict_std_compliance

int Dav1dSettings::strict_std_compliance

whether to abort decoding on standard compliance violations that don't affect actual bitstream decoding (e.g. inconsistent or invalid metadata, default 0)
