Function Documentation

ff_hevc_parse_sps()

int ff_hevc_parse_sps	(	HEVCSPS *	sps,
		GetBitContext *	gb,
		unsigned int *	sps_id,
		int	apply_defdispwin,
		AVBufferRef **	vps_list,
		AVCodecContext *	avctx
	)

Parse the SPS from the bitstream into the provided HEVCSPS struct.

Parameters

sps_id	the SPS id will be written here
apply_defdispwin	if set 1, the default display window from the VUI will be applied to the video dimensions
vps_list	if non-NULL, this function will validate that the SPS refers to an existing VPS
