Syntax
public sealed class AviHeader : CustomPackage

The AviHeader type exposes the following members.

Constructors
  NameDescription
Public methodAviHeader
Initializes a new instance of the AviHeader class.
Properties
  NameDescription
Public propertyAviHeaderFlags
Gets a bitwise combination of zero or more of the AVI flags.
Public propertyCount
Gets the number of metadata properties.
(Inherited from MetadataPackage.)
Public propertyHeight
Gets the height of the AVI file in pixels.
Public propertyInitialFrames

Gets the initial frame for interleaved files.
Noninterleaved files should specify zero. If you are creating interleaved files, specify the number of frames in the file prior to the initial frame of the AVI sequence in this member.

Public propertyItem
Gets the MetadataProperty with the specified name.
(Inherited from MetadataPackage.)
Public propertyKeys
Gets a collection of the metadata property names.
(Inherited from MetadataPackage.)
Public propertyKnowPropertyDescriptors Obsolete.
Gets a collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine.
(Inherited from MetadataPackage.)
Public propertyMaxBytesPerSec

Gets the approximate maximum data rate of the file.
This value indicates the number of bytes per second the system must handle to present an AVI sequence as specified by the other parameters contained in the main header and stream header chunks.

Public propertyMetadataType
Gets the metadata type.
(Inherited from MetadataPackage.)
Public propertyMicroSecPerFrame
Gets the the number of microseconds between frames. This value indicates the overall timing for the file.
Public propertyPaddingGranularity
Gets the alignment for data, in bytes. Pad the data to multiples of this value.
Public propertyPropertyDescriptors
Gets a collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine.
(Inherited from MetadataPackage.)
Public propertyStreams
Gets the number of streams in the file. For example, a file with audio and video has two streams.
Public propertySuggestedBufferSize

Gets the suggested buffer size for reading the file.
Generally, this size should be large enough to contain the largest chunk in the file. If set to zero, or if it is too small, the playback software will have to reallocate memory during playback, which will reduce performance. For an interleaved file, the buffer size should be large enough to read an entire record, and not just a chunk.

Public propertyTotalFrames
Gets the the total number of frames of data in the file.
Public propertyWidth
Gets the width of the AVI file in pixels.
Methods
  NameDescription
Public methodAddProperties
Adds known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.
(Inherited from MetadataPackage.)
Public methodContains
Determines whether the package contains a metadata property with the specified name.
(Inherited from MetadataPackage.)
Public methodEquals (Inherited from Object.)
Public methodFindProperties
Finds the metadata properties satisfying the specified predicate. The search is recursive so it affects all nested packages as well.
(Inherited from MetadataPackage.)
Public methodGetEnumerator
Returns an enumerator that iterates through the collection.
(Inherited from MetadataPackage.)
Public methodGetHashCode (Inherited from Object.)
Public methodGetType (Inherited from Object.)
Public methodRemoveProperties
Removes metadata properties satisfying the specified predicate.
(Inherited from MetadataPackage.)
Public methodSanitize
Removes writable metadata properties from the package. The operation is recursive so it affects all nested packages as well.
(Inherited from MetadataPackage.)
Public methodSetProperties
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(FuncMetadataProperty, Boolean, PropertyValue) and UpdateProperties(FuncMetadataProperty, Boolean, PropertyValue). 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.
(Inherited from MetadataPackage.)
Public methodToString (Inherited from Object.)
Public methodUpdateProperties
Updates known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.
(Inherited from MetadataPackage.)
