Assembly: Aurigma.GraphicsMill.Codecs.AviProcessor (in Aurigma.GraphicsMill.Codecs.AviProcessor.dll)

Syntax

Visual Basic

Public Function AddAudioStream ( _
	fileName As String, _
	sourceOffset As Integer, _
	duration As Integer, _
	cutToVideoDuration As Boolean _
) As Integer

C#

public int AddAudioStream(
	string fileName,
	int sourceOffset,
	int duration,
	bool cutToVideoDuration
)

Parameters

fileName

Type: System..::.String

A name of the WAV file to load the audio data from.
sourceOffset

Type: System..::.Int32

An offset of the source audio data (in 1/100 of seconds). In other words, how many data to skip from the source file.
duration

Type: System..::.Int32

A length of the audio data (in 1/100 of seconds) to add.
cutToVideoDuration

Type: System..::.Boolean

A Boolean value that specifies whether to truncate audio data to fit the duration of the video.

Note

Keep in mind that video duration is determined in the moment when you call this method. It means that if you:

  1. Add half of frames;
  2. Add audio stream with this argument = true;
  3. Add the rest frames;

only the first half of frames will be dubbed. The rest frames will be silent.

That is the reason why it is important to add audio data only when you add all video frames. You can use this fact to synchronize audio and video though.

Return Value

An integer value which specifies the index of new audio stream in the AVI file.

Remarks

Note

You can use this member only if you get this instance of the AviAudioManager from the writer object.
