Function Documentation

AVVorbisParseContext* av_vorbis_parse_init	(	const uint8_t *	extradata,
		int	extradata_size
	)

Allocate and initialize the Vorbis parser using headers in the extradata.

Parameters

avctx	codec context
s	Vorbis parser context

void av_vorbis_parse_free

(

AVVorbisParseContext **

s

)

Free the parser and everything associated with it.

int av_vorbis_parse_frame_flags	(	AVVorbisParseContext *	s,
		const uint8_t *	buf,
		int	buf_size,

Get the duration for a Vorbis packet.

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

Parameters

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