    • Constructor Detail

      • AudioSilenceCaptureDevice

        public AudioSilenceCaptureDevice​(boolean clockOnly)
        Initializes a new AudioSilenceCaptureDevice.
        Parameters:
        clockOnly - whether the AudioSilenceCaptureDevice.AudioSilenceStreams created by this instance are to be used only for the purpose of ticking the clock which makes AudioMixer run.

    • Method Detail

      • createStream

        protected org.jitsi.impl.neomedia.device.AudioSilenceCaptureDevice.AudioSilenceStream createStream​(int streamIndex,
                                                                                                   javax.media.control.FormatControl formatControl)
        Create a new PushBufferStream which is to be at a specific zero-based index in the list of streams of this PushBufferDataSource. The Format-related information of the new instance is to be abstracted by a specific FormatControl. Implements AbstractPushBufferCaptureDevice.createStream(int, FormatControl).
        Specified by:
        createStream in class AbstractPushBufferCaptureDevice
        Parameters:
        streamIndex - the zero-based index of the PushBufferStream in the list of streams of this PushBufferDataSource
        formatControl - the FormatControl which is to abstract the Format-related information of the new instance
        Returns:
        a new PushBufferStream which is to be at the specified streamIndex in the list of streams of this PushBufferDataSource and which has its Format-related information abstracted by the specified formatControl

      • getSupportedFormats

        protected javax.media.Format[] getSupportedFormats​(int streamIndex)
        Gets the Formats which are to be reported by a FormatControl as supported formats for a PushBufferStream at a specific zero-based index in the list of streams of this PushBufferDataSource. Overrides the super implementation in order to return the list of Formats hardcoded as supported in AudioSilenceCaptureDevice because the super looks them up by CaptureDeviceInfo and this instance does not have one.
        Overrides:
        getSupportedFormats in class AbstractPushBufferCaptureDevice
        Parameters:
        streamIndex - the zero-based index of the PushBufferStream for which the specified FormatControl is to report the list of supported Formats
        Returns:
        an array of Formats to be reported by a FormatControl as the supported formats for the PushBufferStream at the specified streamIndex in the list of streams of this PushBufferDataSource
