GI.GES.Objects.ClipAsset

The UriClipAsset is a special Asset specilized in Clip. it is mostly used to get information about the TrackType-s the objects extracted from it can potentialy create TrackElement for.

class (GObject o, IsDescendantOf ClipAsset o) => IsClipAsset o

Type class for types which can be safely cast to ClipAsset, for instance with toClipAsset.

toClipAsset :: (MonadIO m, IsClipAsset o) => o -> m ClipAsset

Cast to ClipAsset, for types for which this is known to be safe. For general casts, use castTo.

getFrameTime

clipAssetGetFrameTime

Arguments

:: (HasCallStack, MonadIO m, IsClipAsset a)

=> a

self: The object for which to compute timestamp for specifed frame

-> Int64

frameNumber: The frame number we want the internal time coordinate timestamp of

-> m Word64

Returns: The timestamp corresponding to frameNumber in the element source, given in internal time coordinates, or CLOCK_TIME_NONE if the clip asset does not have a natural frame rate.

Converts the given frame number into a timestamp, using the "natural" frame rate of the asset.

You can use this to reference a specific frame in a media file and use this as, for example, the in-point or max-duration of a Clip.

Since: 1.18

getNaturalFramerate

clipAssetGetNaturalFramerate

Arguments

:: (HasCallStack, MonadIO m, IsClipAsset a)

=> a

self: The object from which to retrieve the natural framerate

-> m (Bool, Int32, Int32)

Result: True if self has a natural framerate False otherwise

Since: 1.18

getSupportedFormats

clipAssetGetSupportedFormats

Arguments

:: (HasCallStack, MonadIO m, IsClipAsset a)

=> a

self: a ClipAsset

-> m [TrackType]

Returns: The track types on which self will create TrackElement when added to a layer

Gets track types for which objects extracted from self can create TrackElement

setSupportedFormats

clipAssetSetSupportedFormats

Arguments

:: (HasCallStack, MonadIO m, IsClipAsset a)

=> a

self: a ClipAsset

-> [TrackType]

supportedformats: The track types supported by the GESClipAsset

-> m ()

Sets track types for which objects extracted from self can create TrackElement

Properties

supportedFormats

The formats supported by the asset.

constructClipAssetSupportedFormats :: (IsClipAsset o, MonadIO m) => [TrackType] -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “supported-formats” property. This is rarely needed directly, but it is used by new.

getClipAssetSupportedFormats :: (MonadIO m, IsClipAsset o) => o -> m [TrackType]

Get the value of the “supported-formats” property. When overloading is enabled, this is equivalent to

get clipAsset #supportedFormats

setClipAssetSupportedFormats :: (MonadIO m, IsClipAsset o) => o -> [TrackType] -> m ()

Set the value of the “supported-formats” property. When overloading is enabled, this is equivalent to

set clipAsset [ #supportedFormats := value ]
