GI.Gst.Structs.ProtectionMeta

Metadata type that holds information about a sample from a protection-protected track, including the information needed to decrypt it (if it is encrypted).

Since: 1.6

Exported types

newtype ProtectionMeta

Memory-managed wrapper type.

Constructors

ProtectionMeta (ManagedPtr ProtectionMeta)

Instances

WrappedPtr ProtectionMeta

Defined in GI.Gst.Structs.ProtectionMeta

Methods

wrappedPtrCalloc :: IO (Ptr ProtectionMeta)

wrappedPtrCopy :: ProtectionMeta -> IO ProtectionMeta

wrappedPtrFree :: Maybe (GDestroyNotify ProtectionMeta)

tag ~ AttrSet => Constructible ProtectionMeta tag

Defined in GI.Gst.Structs.ProtectionMeta

Methods

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

newZeroProtectionMeta :: MonadIO m => m ProtectionMeta

Construct a ProtectionMeta struct initialized to zero.

noProtectionMeta :: Maybe ProtectionMeta

A convenience alias for Nothing :: Maybe ProtectionMeta.

Methods

getInfo

protectionMetaGetInfo :: (HasCallStack, MonadIO m) => m MetaInfo

No description available in the introspection data.

Properties

info

the cryptographic information needed to decrypt the sample.

clearProtectionMetaInfo :: MonadIO m => ProtectionMeta -> m ()

Set the value of the “info” field to Nothing. When overloading is enabled, this is equivalent to

clear #info

getProtectionMetaInfo :: MonadIO m => ProtectionMeta -> m (Maybe Structure)

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

get protectionMeta #info

setProtectionMetaInfo :: MonadIO m => ProtectionMeta -> Ptr Structure -> m ()

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

set protectionMeta [ #info := value ]

meta

the parent Meta.

getProtectionMetaMeta :: MonadIO m => ProtectionMeta -> m Meta

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

get protectionMeta #meta
