Detailed Description

Vorbis audio parser.

Determines the duration for each packet.

Definition in file vorbis_parser_internal.h.

Function Documentation

int avpriv_vorbis_parse_extradata	(	AVCodecContext *	avctx,
		AVVorbisParseContext *	s
	)

Initialize the Vorbis parser using headers in the extradata.

Parameters

avctx	codec context
s	Vorbis parser context

Definition at line 300 of file vorbis_parser.c.

int avpriv_vorbis_parse_frame_flags	(	AVVorbisParseContext *	s,
		const uint8_t *	buf,
		int	buf_size,
		int *	flags
	)

Get the duration for a Vorbis packet.

avpriv_vorbis_parse_extradata() must have been successfully called prior to this in order for a correct duration to be returned. If flags is NULL, special frames are considered invalid.

Parameters

s	Vorbis parser context
buf	buffer containing a Vorbis frame
buf_size	size of the buffer
flags	flags for special frames

Definition at line 313 of file vorbis_parser.c.

int avpriv_vorbis_parse_frame	(	AVVorbisParseContext *	s,
		const uint8_t *	buf,
		int	buf_size
	)

Get the duration for a Vorbis packet.

avpriv_vorbis_parse_extradata() must have been successfully called prior to this in order for a correct duration to be returned.

Parameters

s	Vorbis parser context
buf	buffer containing a Vorbis frame
buf_size	size of the buffer
