This structure describes how to handle film grain synthesis in video for specific codecs. Must be present on every frame where film grain is meant to be synthesised for correct presentation.

@note The struct must be allocated with av_film_grain_params_alloc() and its size is not a part of the public ABI.

Fields

type_: u32

Specifies the codec for which this structure is valid.

seed: u64

Seed to use for the synthesis process, if the codec allows for it.

@note For H.264, this refers to pic_offset as defined in SMPTE RDD 5-2006.

codec: AVFilmGrainParams__bindgen_ty_1

width: i32

Intended display resolution. May be 0 if the codec does not specify any restrictions.

height: i32

Intended display resolution. May be 0 if the codec does not specify any restrictions.

subsampling_x: i32

Intended subsampling ratio, or 0 for luma-only streams.

subsampling_y: i32

Intended subsampling ratio, or 0 for luma-only streams.

color_range: u32

Intended video signal characteristics.

color_primaries: u32

color_trc: u32

color_space: u32

bit_depth_luma: i32

Intended bit depth, or 0 for unknown/unspecified.

bit_depth_chroma: i32
