ff_dovi_update_cfg()

void ff_dovi_update_cfg	(	DOVIContext *	s,
		const AVDOVIDecoderConfigurationRecord *	cfg

ff_dovi_rpu_parse()

int ff_dovi_rpu_parse	(	DOVIContext *	s,
		const uint8_t *	rpu,
		size_t	rpu_size

Parse the contents of a Dovi RPU NAL and update the parsed values in the DOVIContext struct.

Returns 0 or an error code.

The patent mentions another legal value, NLQ_MU_LAW, but it's not documented anywhere how to parse or apply that type of NLQ.
