Function Documentation

◆ rocDecCreateVideoParser()

rocDecodeStatus ROCDECAPI rocDecCreateVideoParser	(	RocdecVideoParser *	parser_handle,
		RocdecParserParams *	params
	)

Create video parser object and initialize

◆ rocDecDestroyVideoParser()

rocDecStatus ROCDECAPI rocDecDestroyVideoParser

(

RocdecVideoParser

parser_handle

)

Destroy the video parser object

◆ rocDecParseVideoData()

rocDecodeStatus 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
