int avpriv_vorbis_parse_frame	(	VorbisParseContext *	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
