SDID_block_number	int	r/w	Secondary Data identification (if type 2) or Data block number (if type 1)
c_not_y_channel	bool	r/w	Which channel (luminance or chrominance) the ancillary data is located. 0 if content is SD or stored in the luminance channel (default). 1 if HD and stored in the chrominance channel.

data	int	r/w	The User data
data_count	int	r/w	The amount of user data
field	GstVideo.AncillaryMetaField	r/w	The field where the ancillary data is located
line	int	r/w	The line on which the ancillary data is located (max 11bit). There are two special values: 0x7ff if no line is specified (default), 0x7fe to specify the ancillary data is on any valid line before active video
meta	Gst.Meta	r/w	Parent Gst.Meta
offset	int	r/w	The location of the ancillary data packet in a SDI raster relative to the start of active video (max 12bits). A value of 0 means the ADF of the ancillary packet starts immediately following SAV.
