Detailed Description

Vorbis audio parser.

Determines the duration for each packet.

Function Documentation

av_vorbis_parse_frame()

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

Get the duration for a Vorbis packet.

Parameters

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

av_vorbis_parse_frame_flags()

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

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
