◆ AVFilmGrainParamsType

Enumerator
AV_FILM_GRAIN_PARAMS_NONE
AV_FILM_GRAIN_PARAMS_AV1	The union is valid when interpreted as AVFilmGrainAOMParams (codec.aom)
AV_FILM_GRAIN_PARAMS_H274	The union is valid when interpreted as AVFilmGrainH274Params (codec.h274)

Definition at line 24 of file film_grain_params.h.

AVFilmGrainParams * av_film_grain_params_alloc ( size_t * size )

Allocate an AVFilmGrainParams structure and set its fields to default values.

The resulting struct can be freed using av_freep(). If size is not NULL it will be set to the number of bytes allocated.

Returns: An AVFilmGrainParams filled with default values or NULL on failure.

AVFilmGrainParams * av_film_grain_params_create_side_data ( AVFrame * frame )

Allocate a complete AVFilmGrainParams and add it to the frame.

Parameters

frame The frame which side data is added to.
