Datastead TVideoGrabber SDK

Type of the AudioSource property.

Declaration
TAudioSource=(as_Default, as_UseExternalAudio);

enum TAudioSource as_Default, as_UseExternalAudio ;

Description

Type of the AudioSource property.

Possible values:

as_Default:

uses the audio output of the video capture device if any, otherwise uses the current audio capture device.

always uses the current audio capture device for the audio recording, even if the current source (e.g. an URL) exposes an audio output.

as_SpeakerOutput:

uses the soundboard's audio output (captures whatever is rendered)

as_DefaultWithSpeakerRecording: (during recording only)

if AudioDeviceRendering is enabled, the audio of the current source is rendered, but the soundboard's audio output is recorded

as_silent

generates an "empty" audio stream

as_IPCamera

allows to use an IP camera as audio source when previewing or recording an USB source, the screen or the video mixer (when VideoSource = vs_VideoCaptureDevice, vs_ScreenRecording or vs_Mixer).

VideoGrabber.IPCameraURL and eventually the VideoGrabber.SetAuthentication (at_IPCamera, ...) must be set accordingly.
