Detailed Description

ADTF Playback Service Control interface to control the ADTF Player.

This interface enables you to control an instance of ADTF Playback Service. Usually the ADTF Playback Service will be controlled by the ADTFDAT File Player. By following code the service will be controlled by you. Make sure the property "enable_control" is set to false, if you want to control it by yourself.

ucom::object_ptr<IPlayer> pPlayer;
// MIND: This call will only succeed if player is present and it will be called _AFTER_ the PlaybackService was initialized! 
if (IS_OK(get_player(pPlayer))
{
    if (IS_OK(pPlayer->Open("c:/temp/my_test_file.adtfdat", true)))
    {
        pPlayer->Play();
    }
}
 

Remarks: Usually this Playback interface and the states of the Player does NOT depend on the Runlevel. Only the concrete implementation of the ADTFDAT File Player maps it to the StreamingGraph State.

Member Function Documentation

◆ Close()

virtual tResult Close ( )

pure virtual

Closes the current loaded files.

The playback of a recently opened adtfdat file will be stopped and closed. Also if error occures the new state is closed.

Return values

ERR_NOERROR Files successfully closed - State is now tState::Closed.

◆ GetChunkCount()

virtual uint64_t GetChunkCount ( ) const

pure virtual

Information interface to get the chunk count of the current opened files.

Returns: chunk count

Return values

0	no file is opend

◆ GetCurrentFileNames()

virtual tResult GetCurrentFileNames ( base::ant::IString && strFileNames ) const

pure virtual

Information interface to get the time range of the current opened file.

Parameters

strFileNames [out] String where to return the filenames to. (comma separated list)

Remarks: It will only return valid values if ERR_NOERROR is returned.

Return values

ERR_NOERROR State change succeded

◆ GetCurrentState()

virtual IPlayer::tState GetCurrentState ( ) const

pure virtual

Information interface to get the current state of the Player.

Remarks: It will only return valid values if ERR_NOERROR is returned.

Return values

the	State of the player

◆ GetCurrentTime()

virtual tTimeStamp GetCurrentTime ( ) const

pure virtual

Information interface to get the current time position of the current opened files.

Returns: The time between GetTimeRange

Return values

<0	No files are opend

See also: GetTimeRange

◆ GetTimeRange()

virtual tResult GetTimeRange	(	tTimeStamp &	tmFirstItem,
		tTimeStamp &	tmLastItem ) const

pure virtual

Information interface to get the time range of the currently opened files.

Parameters

tmFirstItem	[out] (Chunk)Time of the first item
tmLastItem	[out] (Chunk)Time of the last item

Remarks: It will only return valid values if ERR_NOERROR is returned.

Return values

ERR_NOERROR File is at least opend and information where read.

◆ ListStreams()

virtual tResult ListStreams ( IListStreamCallback & oCallback )

pure virtual

List all available streams.

Parameters

[in] oCallback The callback that retrieves all streams.

◆ Open()

virtual tResult Open	(	const char *	strFileNames,
		bool	bLoadReferencedFiles )

pure virtual

Opens one or more adtfdat files.

Remarks: The playback of a recently opened adtfdat file will be stopped and closed before a new file is opened. If the open fails the recently the state was changed to close!

Parameters

strFileNames	[in] List of Files to open at once. (comma separated list)
bLoadReferencedFiles	[in] open files which are added to the file extension "referenced_files".

Return values

ERR_NOERROR Files successfully opend - State is now tState::Opened.

Returns: Standard Result Code

◆ Play()

virtual tResult Play ( )

pure virtual

Control interface to start streaming.

Returns: Standard Result Code

◆ Reset()

virtual tResult Reset ( )

pure virtual

Control interface to Reset the streaming.

virtual tResult SeekToChunkIndex ( uint64_t ui64ChunkIndex )

pure virtual

Control interface to seek to the given (Chunk) Index.

Returns: Standard Result Code

◆ SeekToStreamIndex()

virtual tResult SeekToStreamIndex	(	uint16_t	ui16StreamId,
		uint64_t	ui64StreamIndex )

pure virtual

Control interface to seek to the given (Stream) Index of the given stream.

Returns: Standard Result Code

◆ SeekToTime()

virtual tResult SeekToTime ( tTimeStamp tmTime )

pure virtual

Control interface to seek to the given (Chunk) Time.

Returns: Standard Result Code
