ltmmCaptureCtrl.UseVideoDeviceAudio Property

Visual Basic Example

Remarks

Indicates whether the audio source in the video device is used. Possible values are:

The default value for this property is TRUE. It specifies whether the ltmmCaptureCtrl object will use the audio from the video device if no audio device has been explicitly selected. For instance, DV DV stands for Digital Video and has been defined in "Specification of Consumer-use Digital VCRs" (aka the Blue Book). devices contain both audio and video. Normally, if you select a DV device with no audio device, the toolkit will use the DV device's audio stream The portion of the file holding the audio data. The audio data might be compressed to save disk space. The data has to be decompressed using an audio decompressor oftware component which decompresses audio. It must be designed to work with ACM or DirectShow. Note that different compression methods require different decompressors. There is no universal decompressor capable of decoding all compressed streams. before you can play (hear) it.. However, if you set this property to FALSE, then no audio stream will be rendered. This helps build a slightly more efficient graph when processing video only from DV devices.
