Constructor Detail

StreamBufferCaptureSource

public StreamBufferCaptureSource(DSFilterInfo info)

Constructs a StreamBufferCaptureSource for MPEG2 or DV capture devices. To find valid devices use the getStreamBufferCaptureDevices(true) method in DSStreamBufferGraph.

StreamBufferCaptureSource

public StreamBufferCaptureSource(DSFilterInfo vInfo,
                                 DSFilterInfo aInfo,
                                 int dvFlags)

Constructs a StreamBufferCaptureSource for "standard" non MPEG2 or DV capture devices. As the StreamBufferEngine works with DV or MPEG2 only, dsj will build a sourcegraph that converts the devices' output to DV before feeding it into the Sink. %dvFlags controls the DVEncoder, set to 1 for PAL, 0 for NTSC.
