TAudioSource
TAudioSource = (as_Default, as_UseExternalAudio, as_UseMixAudioSample, as_SpeakerOutput, as_DefaultWithSpeakerRecording, as_Silent, as_IPcamera);
Type of the AudioSource property.
Possible values:
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. a URL) exposes an audio output.
uses the sound card's audio output (captures whatever is rendered)
if AudioDeviceRendering is enabled, the audio of the current source is rendered, but the sound card's audio output is recorded
as_silent
generates an "empty" audio stream
as_IPCamera
allows using an IP camera as the audio source when previewing or recording a USB source, the screen or the video mixer (when VideoSource = vs_VideoCaptureDevice, vs_ScreenRecording or vs_Mixer).
VideoGrabber.IPCameraURL and, if needed, VideoGrabber.SetAuthentication (at_IPCamera, ...) must be set accordingly.
