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. |
