rocDecStatus ROCDECAPI rocDecParseVideoData	(	RocdecVideoParser	parser_handle,
		RocdecSourceDataPacket *	packet
	)

Parse the video data from source data packet in pPacket.

Extracts parameter sets like SPS, PPS, bitstream etc. from pPacket and calls back pfn_decode_picture with RocdecPicParams data for kicking of HW decoding calls back pfn_sequence_callback with RocdecVideoFormat data for initial sequence header or when the decoder encounters a video format change calls back pfn_display_picture with RocdecParserDispInfo data to display a video frame
