Properties

AdvancedSettings

Gets the advanced settings for the adaptive media source.

AudioOnlyPlayback

Gets a value indicating if the content streamed by the media source contains only audio.

AvailableBitrates

Gets the available adaptive bit rates of the adaptive streaming manifest that is the source of the adaptive streaming object.

CurrentDownloadBitrate

Gets a value indicating the current download bitrate for the media source.

CurrentPlaybackBitrate

Gets a value indicating the current playback bitrate for the media source.

DesiredLiveOffset

Gets or sets the desired offset of live playback from the end of the known media content that has been downloaded.

DesiredMaxBitrate

Gets or sets the desired maximum bitrate for the media source.

DesiredMinBitrate

Gets or sets the desired minimum bitrate for the media source.

DesiredSeekableWindowSize

Gets or sets the requested maximum size of the time window within which the user can seek within the streaming media.

Diagnostics

Gets an object that provides an event that is raised when diagnostic information about the adaptive media source is available.

InboundBitsPerSecond

Gets a value indicating the inbound bits per second statistic over the time window specified by the InboundBitsPerSecondWindow property.

InboundBitsPerSecondWindow

Gets or sets the time span over which the InboundBitsPerSecond property is calculated.

InitialBitrate

Gets and sets the initial bit rate to use for playback of the media source.

IsLive

Gets a value that indicates whether the media source is live.

MaxSeekableWindowSize

Gets the maximum time window within which the user can seek within the streaming media.

MinLiveOffset

Gets the minimum offset of live playback from the end of the known media content that has been downloaded.

Methods

Close()

Closes the adaptive media source and frees up associated resources.

CreateFromStreamAsync(IInputStream, Uri, String)

Asynchronously creates a AdaptiveMediaSource object from the provided input stream.

CreateFromStreamAsync(IInputStream, Uri, String, HttpClient)

Asynchronously creates a AdaptiveMediaSource object from the provided input stream.

CreateFromUriAsync(Uri)

Asynchronously creates a AdaptiveMediaSource object from the Uniform Resource Identifier (URI) of the source.

CreateFromUriAsync(Uri, HttpClient)

Asynchronously creates a AdaptiveMediaSource object from the Uniform Resource Identifier (URI) of the source.

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

GetCorrelatedTimes()

Gets an object that provides timing information that is correlated between timestamps in the media or date/time information from the manifest with the presentation clock timeline.

IsContentTypeSupported(String)

Determines whether the content type of the source is supported.

Events

DownloadBitrateChanged

Occurs when the CurrentDownloadBitrate changes.

DownloadCompleted

Occurs when a resource download operation completes

DownloadFailed

Occurs when a resource download operation fails.

DownloadRequested

Occurs when a resource download operation is requested.

PlaybackBitrateChanged

Occurs when the CurrentPlaybackBitrate changes.
