Properties

AudioGain

Gets or sets the gain (input amplification) of the audio track. Any value greater than or equal to 0.0 is valid. The default value is 1. If there are multiple audio tracks in a custom media stack, this property is bound to the first audio track.

Declaration

public double AudioGain { get; set; }

System.Int32

AudioMuted

Gets or sets a value indicating whether the audio is muted. This method silences audio but does not disable the audio source or prevent its data from flowing through the processing pipeline. If there are multiple audio tracks in a custom media stack, this property is bound to the first audio track.

Declaration

public bool AudioMuted { get; set; }

Property Value

Type	Description
System.Boolean

AudioTrack

Gets the audio track from this media. If there are multiple audio tracks in a custom media stack, this property is bound to the first audio track. Returns null if there are no audio tracks.

Declaration

public TIAudioTrack AudioTrack { get; }

Property Value

Type	Description
TIAudioTrack

AudioTracks

Gets all audio tracks from this media.

Declaration

public abstract TIAudioTrack[] AudioTracks { get; }

Property Value

Type	Description
TIAudioTrack[]

AudioVolume

Gets or sets the audio volume on the audio track. Valid values range between 0.0 and 1.0. A value of 1.0 indicates that there is no output resistance on the audio and it is played back at the input level. A value of 0.0 mutes the audio.
If there are multiple audio tracks in a custom media stack, this property is bound to the first audio track.

Declaration

public double AudioVolume { get; set; }

Property Value

Declaration

public bool VideoMuted { get; set; }

Property Value

Type	Description
System.Boolean

VideoSize

Gets the size of the last processed video frame, if known. If there are multiple video tracks in a custom media stack, this property is bound to the first video track.

Declaration

public abstract Size VideoSize { get; }

Property Value

Type	Description
Size

VideoTrack

Gets the video track from this media.
If there are multiple video tracks in a custom media stack, this property is bound to the first video track. Returns null if there are no video tracks.

Property Value

Type	Description
TIVideoTrack

VideoTracks

Gets all video tracks from this media.

Declaration

public abstract TIVideoTrack[] VideoTracks { get; }

Property Value

Type	Description
TIVideoTrack[]

Methods

Destroy()

Destroys this media stack.

Declaration

public abstract void Destroy()

GrabVideoFrame()

Gets the next raw video frame. If there are multiple video tracks in a custom media stack, this method calls into the first video track.

Declaration

public abstract Future<VideoBuffer> GrabVideoFrame()

Returns

Type	Description
Future<VideoBuffer>	A future video buffer.

SetAudioMutedInternal(Boolean)

Synchronizes the muted status of the internal elements.

Declaration

protected virtual void SetAudioMutedInternal(bool muted)

Parameters

Type	Name	Description
