AviAudioManager.AppendAudioStream Method (Int32, String, Int32, Int32, Boolean)

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

Syntax

Visual Basic 
Public Sub AppendAudioStream ( _
	streamIndex As Integer, _
	fileName As String, _
	sourceOffset As Integer, _
	duration As Integer, _
	cutToVideoDuration As Boolean _
)
C# 
public void AppendAudioStream(
	int streamIndex,
	string fileName,
	int sourceOffset,
	int duration,
	bool cutToVideoDuration
)

Parameters

streamIndex

Type: System.Int32

An index of the stream you want to append the audio data with.

Note

Make sure that the audio stream with such index exists in the AVI file you create.

fileName

Type: System.String

A string which specifies the name of the WAV file you want to append to the audio stream.
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.

Remarks

Note

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