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.
