AVTransportState (Windows Embedded CE 6.0)

1/6/2010

These constants contain the names of state variables evented by the AVTransport service.

Syntax

const LPCWSTR 
  // TransportInfo
  TransportState          = L"TransportState",
  TransportStatus         = L"TransportStatus",
  PlaySpeed               = L"TransportPlaySpeed",
  // PositionInfo
  CurrentTrack            = L"CurrentTrack",
  CurrentTrackDuration    = L"CurrentTrackDuration",
  CurrentTrackMetaData    = L"CurrentTrackMetaData",
  CurrentTrackURI         = L"CurrentTrackURI",
  RelTime                 = L"RelativeTimePosition",
  AbsTime                 = L"AbsoluteTimePosition",
  RelCounter              = L"RelativeCounterPosition",
  AbsCounter              = L"AbsoluteCounterPosition",
  // DeviceCapabilities
  PossiblePlayMedia       = L"PossiblePlaybackStorageMedia",
  PossibleRecMedia        = L"PossibleRecordStorageMedia",
  PossibleRecQualityModes = L"PossibleRecordQualityModes",
  // TransportSettings
  PlayMode                = L"CurrentPlayMode",
  RecQualityMode          = L"CurrentRecordQualityMode",
  // CurrentTransportActions
  CurrentTransportActions = L"CurrentTransportActions",
  // MediaInfo
  NrTracks                = L"NumberOfTracks",
  MediaDuration           = L"CurrentMediaDuration",
  CurrentURI              = L"AVTransportURI",
  CurrentURIMetaData      = L"AVTransportURIMetaData",
  NextURI                 = L"NextAVTransportURI",
  NextURIMetaData         = L"NextAVTransportURIMetaData",
  PlaybackMedia           = L"PlaybackStorageMedium",
  RecordMedia             = L"RecordStorageMedium",
  WriteStatus             = L"RecordMediumWriteStatus";

Remarks

Using IEventSink::OnStateChanged, applications that use or implement the AVTransport service use these constants to receive and send event notifications when evented state variables change.
