MatroskaEbmlHeader class

Represents EBML header metadata in a Matroska video.

Inheritance: MatroskaEbmlHeader → MatroskaBasePackage → CustomPackage → MetadataPackage

The MatroskaEbmlHeader type exposes the following members:

Property	Description
metadata_type	Gets the metadata type.
keys	Gets a collection of the metadata property names.
property_descriptors	Gets a collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine.
count	Gets the number of metadata properties.
version	Gets the version of the EBML Writer that has been used to create the file.
read_version	Gets the minimum version an EBML parser needs to be compliant with to be able to read the file.
doc_type	Gets the contents of the file. In the case of a MATROSKA file, its value is ‘matroska’.
doc_type_version	Gets the version of the `MatroskaEbmlHeader.doc_type` writer used to create the file.
doc_type_read_version	Gets the minimum version number a `MatroskaEbmlHeader.doc_type` parser must be compliant with to read the file.

Method	Description
`contains(self, property_name)`	Determines whether the package contains a metadata property with the specified name.
`find_properties(self, specification)`	Finds the metadata properties satisfying a specification. The search is recursive so it affects all nested packages as well.
`update_properties(self, specification, value)`	Updates known metadata properties satisfying a specification. The operation is recursive so it affects all nested packages as well.
`remove_properties(self, specification)`	Removes metadata properties satisfying a specification.
`add_properties(self, specification, value)`	Adds known metadata properties satisfying the specification. The operation is recursive so it affects all nested packages as well.
`set_properties(self, specification, value)`	Sets known metadata properties satisfying the specification. The operation is recursive so it affects all nested packages as well. This method is a combination of `MetadataPackage.add_properties` and `MetadataPackage.update_properties`. If an existing property satisfies the specification its value is updated. If there is a known property missing in the package that satisfies the specification it is added to the package.
`sanitize(self)`	Removes writable metadata properties from the package. The operation is recursive so it affects all nested packages as well.
