MatroskaAudioTrack class
Represents audio metadata in a Matroska video.
public class MatroskaAudioTrack : MatroskaTrack
Properties
| Name | Description |
|---|---|
| BitDepth { get; } | Gets the bits per sample, mostly used for PCM. |
| Channels { get; } | Gets the numbers of channels in the track. |
| CodecID { get; } | Gets an ID corresponding to the codec. |
| CodecName { get; } | Gets a human-readable string specifying the codec. |
| Count { get; } | Gets the number of metadata properties. |
| DefaultDuration { get; } | Gets the number of nanoseconds (not scaled via TimecodeScale) per frame. |
| FlagEnabled { get; } | Gets the enabled flag, true if the track is usable. |
| Item { get; } | Gets the MetadataProperty with the specified name. |
| Keys { get; } | Gets a collection of the metadata property names. |
| Language { get; } | Gets the language of the track in the Matroska languages form. This Element MUST be ignored if the LanguageIetf Element is used in the same TrackEntry. |
| LanguageIetf { get; } | Gets the language of the track according to BCP 47 and using the IANA Language Subtag Registry. If this Element is used, then any Language Elements used in the same TrackEntry MUST be ignored. |
| MetadataType { get; } | Gets the metadata type. |
| Name { get; } | Gets the human-readable track name. |
| OutputSamplingFrequency { get; } | Gets the real output sampling frequency in Hz (used for SBR techniques). |
| PropertyDescriptors { get; } | Gets a collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine. |
| SamplingFrequency { get; } | Gets the sampling frequency in Hz. |
| TrackNumber { get; } | Gets the track number as used in the Block Header. Using more than 127 tracks is not encouraged, though the design allows an unlimited number. |
| TrackType { get; } | Gets the type of the track. |
| TrackUid { get; } | Gets the unique ID to identify the Track. This SHOULD be kept the same when making a direct stream copy of the Track to another file. |
Methods
| Name | Description |
|---|---|
| virtual AddProperties(Func<MetadataProperty, bool>, PropertyValue) | Adds known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well. |
| Contains(string) | Determines whether the package contains a metadata property with the specified name. |
| virtual FindProperties(Func<MetadataProperty, bool>) | Finds the metadata properties satisfying the specified predicate. The search is recursive so it affects all nested packages as well. |
| GetEnumerator() | Returns an enumerator that iterates through the collection. |
| virtual RemoveProperties(Func<MetadataProperty, bool>) | Removes metadata properties satisfying the specified predicate. |
| virtual Sanitize() | Removes writable metadata properties from the package. The operation is recursive so it affects all nested packages as well. |
| virtual SetProperties(Func<MetadataProperty, bool>, PropertyValue) | Sets known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well. This method is a combination of AddProperties and UpdateProperties. If an existing property satisfies the predicate its value is updated. If there is a known property missing in the package that satisfies the predicate it is added to the package. |
| virtual UpdateProperties(Func<MetadataProperty, bool>, PropertyValue) | Updates known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well. |
