Properties

captionType

The type of Closed Caption contained in the meta.

getVideoCaptionMetaCaptionType :: MonadIO m => VideoCaptionMeta -> m VideoCaptionType

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

get videoCaptionMeta #captionType

setVideoCaptionMetaCaptionType :: MonadIO m => VideoCaptionMeta -> VideoCaptionType -> m ()

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

set videoCaptionMeta [ #captionType := value ]

meta

parent Meta

getVideoCaptionMetaMeta :: MonadIO m => VideoCaptionMeta -> m Meta

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

get videoCaptionMeta #meta

size

The size in bytes of data

getVideoCaptionMetaSize :: MonadIO m => VideoCaptionMeta -> m Word64

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

get videoCaptionMeta #size

setVideoCaptionMetaSize :: MonadIO m => VideoCaptionMeta -> Word64 -> m ()

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

set videoCaptionMeta [ #size := value ]
