-/*!\file
- * \brief A table mapping from time to corresponding film grain parameters.
- *
- * In order to apply grain synthesis in the decoder, the film grain parameters
- * need to be signalled in the encoder. The film grain parameters are time
- * varying, and for two-pass encoding (and denoiser implementation flexibility)
- * it is common to denoise the video and do parameter estimation before encoding
- * the denoised video.
- *
- * The film grain table is used to provide this flexibility and is used as a
- * parameter that is passed to the encoder.
- *
- * Further, if regraining is to be done in say a single pass mode, or in two
- * pass within the encoder (before frames are added to the lookahead buffer),
- * this data structure can be used to keep track of on-the-fly estimated grain
- * parameters, that are then extracted from the table before the encoded frame
- * is written.
