Function Documentation

int sceAsfCheckNeedMem

(

SceAsfParser *

parser

)

Check the memory of an asf parser.

Parameters

parser

- pointer to a SceAsfParser struct

Returns

< 0 if error else if (parser->iNeedMem > 0x8000) also error.

int sceAsfGetFrameData	(	SceAsfParser *	parser,
		int	unknown,
		SceAsfFrame *	frame
	)

Get frame in asf stream.

Parameters

parser	- pointer to a SceAsfParser struct
unknown	- unknown, set to 1
frame	- pointer to a SceAsfFrame struct

Returns

< 0 if error else success.

int sceAsfInitParser	(	SceAsfParser *	parser,
		ScePVoid	user_data,
		SceAsfParserReadCB	read_cb,
		SceAsfParserSeekCB	seek_cb
	)

Initialize asf parser.

Parameters

parser	- pointer to a SceAsfParser struct
user_data	- user pointer for read/seek callback
read_cb	- read callback
seek_cb	- seek callback

Returns

< 0 if error else success.

int sceAsfParser_685E0DA7	(	SceAsfParser *	asf,
		void *	ptr,
		int	flag,
		void *	arg4,
		SceUInt64 *	start,
		SceUInt64 *	size
	)

Get WMA Tag frame's offset and size.

Parameters

asf	pointer to a SceAsfParser struct
ptr	unknown, pass NULL
start	pointer to frame offset
size	pointer to frame size
flag	can be one of: 0x00000001: get asf file header information 0x00004000: get standard tag information 0x00008000: get extra tag infomration 0x00040000: unknown 0x00080000: unknown

Note

use after sceAsfInitParser completed

int sceAsfParser_C6D98C54	(	SceAsfParser *	asf,
		void *	unk,
		SceUInt64 *	start,
		SceUInt64 *	size
	)

Parameters

asf	pointer to a SceAsfParser struct
unk	unknown, pass NULL
start	pointer to frame offset
size	pointer to frame size

Note

use after sceAsfInitParser completed

int sceAsfSeekTime	(	SceAsfParser *	parser,
		int	unknown,
		SceUInt32 *	ms
	)

Seek in asf stream.

Parameters

parser	- pointer to a SceAsfParser struct
unknown	- unknown, set to 1
ms	- will contain value of seek ms

Returns

< 0 if error else success.
