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

Defined in GI.Gst.Structs.ProtectionMeta new :: MonadIO m => (ManagedPtr ProtectionMeta -> ProtectionMeta) -> [AttrOp ProtectionMeta tag] -> m ProtectionMeta # |

struct initialized to zero.

A convenience alias for Nothing
:: Maybe
ProtectionMeta
.
Methods
getInfo
protectionMetaGetInfo :: (HasCallStack, MonadIO m) => m MetaInfo Source #
No description available in the introspection data.
Properties
info
the cryptographic information needed to decrypt the sample.
clearProtectionMetaInfo :: MonadIO m => ProtectionMeta -> m () Source #
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) Source #
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 () Source #
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 Source #
Get the value of the “meta
” field.
When overloading is enabled, this is equivalent to
get
protectionMeta #meta
