Class JSampleBuffer

java.lang.Object
  de.humatic.dsj.SampleBuffer
      de.humatic.dsj.JSampleBuffer

public class JSampleBuffer
extends SampleBuffer

JSampleBuffer is a typed structure holding a block of data - usually a video- or audioframe - and some related attributes. Unlike DSSampleBuffer JSampleBuffer has no fix association with a Filtergraph and can be kept around over longer times. dsj uses it in the de.humatic.dsj.src.Source derived classes to feed the native source filters with data from the java side.

Constructor Summary

JSampleBuffer(byte[] d, int offset, int last, int time, int sequenceNumber, int inputDelta, int flags)
Constructs a JSampleBuffer by copying data from indices %offset to %last of %d (so that the resulting sample length as returned by getSampleLength() = last-offset) into a newly allocated byte[].

JSampleBuffer(DSMediaType mtype, byte[] d)
Constructs a JSampleBuffer referencing all data in the given byte array.

JSampleBuffer(DSMediaType mtype, byte[] headers, byte[] d, int offset, int last, int time, int sequenceNumber, int inputDelta, int flags)

JSampleBuffer(DSMediaType mtype, byte[] d, int length, int time, int sequenceNumber, int inputDelta, int flags)
Constructs a JSampleBuffer referencing the data in the given byte array between indices 0 and %length.

JSampleBuffer(DSMediaType mtype, byte[] d, int offset, int last, int time, int sequenceNumber, int inputDelta, int flags)
Constructs a JSampleBuffer with the given media type by copying data from indices %offset to %last of %d (so that the resulting sample length as returned by getSampleLength() = last-offset) into a newly allocated byte[].

Constructs a JSampleBuffer by copying data from indices %offset to %last of %d (so that the resulting sample length as returned by getSampleLength() = last-offset) into a newly allocated byte[]. Samples larger than the set maximum in memory size (def.: 128k) will be written to temp files.
