Direct Known Subclasses:

public class BaseCaptureReader
extends BaseReader

All asynchronous reader objects derive from this class. Asynchronous readers are available for image reading (VideoCaptureReader) and audio reading (AudioCaptureReader). Asynchronous readers provide managed performance scaling by default.

The general signaling mechanism provides asynchronous callbacks when processing has been completed on a packet of data (image frame or audio buffer) via the ResultListener.onReaderResult(ReaderResult, ResultType) and ResultListener.onError(com.digimarc.dms.readers.BaseReader.ReaderError, com.digimarc.dms.readers.BaseReader.ResultType) methods. These callbacks are delivered by a separate thread within the capture reader class. The callbacks will always be delivered to your application on the UI thread. Delays in returning from these callbacks will not obstruct the reader itself, but it may cause a backup in the delivery of further notification callbacks.
