addAncillary

videoVBIEncoderAddAncillary

Arguments

:: (HasCallStack, MonadIO m)

=> VideoVBIEncoder

encoder: a VideoVBIEncoder

-> Bool

composite: True if composite ADF should be created, component otherwise

-> Word8

dID: The Data Identifier

-> Word8

sDIDBlockNumber: The Secondary Data Identifier (if type 2) or the Data Block Number (if type 1)

-> ByteString

data: The user data content of the Ancillary packet. Does not contain the ADF, DID, SDID nor CS.

-> m Bool

Returns: True if enough space was left in the current line, False otherwise.

Stores Video Ancillary data, according to SMPTE-291M specification.

Note that the contents of the data are always read as 8bit data (i.e. do not contain the parity check bits).
