addAncillary

videoVBIEncoderAddAncillary Source #

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).

Since: 1.16

copy

videoVBIEncoderCopy :: (HasCallStack, MonadIO m) => VideoVBIEncoder -> m VideoVBIEncoder Source #

No description available in the introspection data.

free

videoVBIEncoderFree Source #

Arguments

:: (HasCallStack, MonadIO m)
=> VideoVBIEncoder	`encoder`: a `VideoVBIEncoder`
-> m ()

Frees the encoder.

Since: 1.16

new

videoVBIEncoderNew Source #

Arguments

:: (HasCallStack, MonadIO m)
=> VideoFormat	`format`: a `VideoFormat`
-> Word32	`pixelWidth`: The width in pixel to use
-> m VideoVBIEncoder	Returns: The new `VideoVBIEncoder` or `Nothing` if the `format` and/or `pixelWidth` is not supported.

Create a new VideoVBIEncoder for the specified format and pixelWidth.

Since: 1.16

writeLine
