GI.Gst.Structs.StaticCaps

Datastructure to initialize Caps from a string description usually used in conjunction with GST_STATIC_CAPS() and staticCapsGet to instantiate a Caps.

Exported types

newtype StaticCaps

Constructors

StaticCaps (ManagedPtr StaticCaps)

Instances

WrappedPtr StaticCaps

Methods

wrappedPtrCalloc :: IO (Ptr StaticCaps)

wrappedPtrCopy :: StaticCaps -> IO StaticCaps

wrappedPtrFree :: Maybe (FunPtr (Ptr StaticCaps -> IO ()))

(~) AttrOpTag tag AttrSet => Constructible StaticCaps tag

Methods

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

newZeroStaticCaps :: MonadIO m => m StaticCaps

Construct a StaticCaps struct initialized to zero.

noStaticCaps :: Maybe StaticCaps

Methods

cleanup

staticCapsCleanup

Arguments

:: (HasCallStack, MonadIO m)

=> StaticCaps

staticCaps: the StaticCaps to clean

-> m ()

Clean up the cached caps contained in staticCaps.

get

staticCapsGet

Arguments

:: (HasCallStack, MonadIO m)

=> StaticCaps

staticCaps: the StaticCaps to convert

-> m Caps

Returns: a pointer to the Caps. Unref after usage. Since the core holds an additional ref to the returned caps, use gst_caps_make_writable() on the returned caps to modify it.

Converts a StaticCaps to a Caps.
