AsfVideoStreamProperty class

AsfVideoStreamProperty class

Represents Video stream property metadata in the ASF media container.

Inheritance: AsfVideoStreamPropertyAsfBaseStreamPropertyCustomPackageMetadataPackage

The AsfVideoStreamProperty type exposes the following members:

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.
stream_type Gets the type of this stream.
stream_number Gets the number of this stream.
start_time Gets the presentation time of the first object, indicating where this digital media stream
starts within the context of the timeline of the ASF file as a whole.
end_time Gets the presentation time of the last object plus the duration of play, indicating where
this digital media stream ends within the context of the timeline of the ASF file as a whole.
bitrate Gets the leak rate R, in bits per second, of a leaky bucket that contains the data portion
of the stream without overflowing, excluding all ASF Data Packet overhead.
alternate_bitrate Gets the leak rate RAlt, in bits per second, of a leaky bucket that contains the data portion
of the stream without overflowing, excluding all ASF Data Packet overhead.
flags Gets the flags.
language Gets the stream language.
average_time_per_frame Gets the average time duration, measured in 100-nanosecond units, of each frame.
average_bitrate Gets the average bitrate.
image_width Gets the width of the encoded image in pixels.
image_height Gets the height of the encoded image in pixels.
compression Gets the video compression Id.
bits_per_pixels Gets the bits per pixels.

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.
