Detailed Description

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.

union { ... } AVFilmGrainParams::codec

Additional fields may be added both here and in any structure included.

If a codec's film grain structure differs slightly over another codec's, fields within may change meaning depending on the type.
