Python-Net: MpegAudioPackage class

Mon, 01 Jan 0001 00:00:00 +0000

MpegAudioPackage class

Represents MPEG audio metadata.

Inheritance: MpegAudioPackage → CustomPackage → MetadataPackage

The MpegAudioPackage type exposes the following members:

Constructors

Constructor	Description
`__init__(self)`	Initializes a new instance of the `MpegAudioPackage` class.

Properties

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.
mpeg_audio_version	Gets the MPEG audio version. Can be MPEG-1, MPEG-2 etc.
layer	Gets the layer description. For an MP3 audio it is ‘3’.
is_protected	Gets `true` if protected.
header_position	Gets the header offset.
bitrate	Gets the bitrate.
frequency	Gets the frequency.
padding_bit	Gets the padding bit.
private_bit	Gets a value indicating whether [private bit].
channel_mode	Gets the channel mode.
copyright	Gets the copyright bit.
is_original	Gets the original bit.
emphasis	Gets the emphasis.
mode_extension_bits	Gets the mode extension bits.

Methods

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.

Example

This example demonstrates how to read MPEG audio metadata from an MP3 file.
