GI.Gst.Structs.MetaTransformCopy

Extra data passed to a "gst-copy" transform MetaTransformFunction.

Exported types

newtype MetaTransformCopy

Memory-managed wrapper type.

Constructors

MetaTransformCopy (ManagedPtr MetaTransformCopy)

Instances

WrappedPtr MetaTransformCopy

Defined in GI.Gst.Structs.MetaTransformCopy

Methods

wrappedPtrCalloc :: IO (Ptr MetaTransformCopy)

wrappedPtrCopy :: MetaTransformCopy -> IO MetaTransformCopy

wrappedPtrFree :: Maybe (GDestroyNotify MetaTransformCopy)

tag ~ AttrSet => Constructible MetaTransformCopy tag

Defined in GI.Gst.Structs.MetaTransformCopy

Methods

new :: MonadIO m => (ManagedPtr MetaTransformCopy -> MetaTransformCopy) -> [AttrOp MetaTransformCopy tag] -> m MetaTransformCopy

newZeroMetaTransformCopy :: MonadIO m => m MetaTransformCopy

Construct a MetaTransformCopy struct initialized to zero.

noMetaTransformCopy :: Maybe MetaTransformCopy

A convenience alias for Nothing :: Maybe MetaTransformCopy.

Properties

offset

the offset to copy, 0 if region is False, otherwise > 0

getMetaTransformCopyOffset :: MonadIO m => MetaTransformCopy -> m Word64

Get the value of the “offset” field. When overloading is enabled, this is equivalent to

get metaTransformCopy #offset

setMetaTransformCopyOffset :: MonadIO m => MetaTransformCopy -> Word64 -> m ()

Set the value of the “offset” field. When overloading is enabled, this is equivalent to

set metaTransformCopy [ #offset := value ]

region

True if only region is copied

getMetaTransformCopyRegion :: MonadIO m => MetaTransformCopy -> m Bool

Get the value of the “region” field. When overloading is enabled, this is equivalent to

get metaTransformCopy #region

setMetaTransformCopyRegion :: MonadIO m => MetaTransformCopy -> Bool -> m ()

Set the value of the “region” field. When overloading is enabled, this is equivalent to

set metaTransformCopy [ #region := value ]

size

the size to copy, -1 or the buffer size when region is False

getMetaTransformCopySize :: MonadIO m => MetaTransformCopy -> m Word64

Get the value of the “size” field. When overloading is enabled, this is equivalent to

get metaTransformCopy #size

setMetaTransformCopySize :: MonadIO m => MetaTransformCopy -> Word64 -> m ()

Set the value of the “size” field. When overloading is enabled, this is equivalent to

set metaTransformCopy [ #size := value ]
