Class VideoHeaderV2

java.lang.Object
  de.desy.acop.video.displayer.VideoHeaderV2

public final class VideoHeaderV2
extends java.lang.Object

VideoHeaderV2 implements marshaling of a Video System v2 (VSv2) data array (usually just received via the network) to a Video System v3 TINE IMAGE datatype for usage with the rest of Video System v3 Java code.

Note:This class is only a very basic construct and might be substantially changed in future. It fits its purpose currently but will not win a price for meaningful class design!

Field Summary

static int	HDRSIZE size in bytes of a VSv2 header that each VSv2 data array starts off with
static long	HUFFYUV_FOURCC video codec typical FOURCC (four character code) of HUFFYUV 'HFYU'

Constructor Summary

VideoHeaderV2()

Method Summary

boolean	packageV2BlobIntoIMAGE(java.lang.String cameraPortName, byte[] imageV2blob, de.desy.tine.types.IMAGE destTineImage) interprets an input array (aImageV2blob) as a Video System v2 data block (header plus possibly additional format header plus image bits).
boolean	parseImageV2blob(byte[] buf) interprets an input array (buffer) as a Video System v2 header.

Method Detail

packageV2BlobIntoIMAGE

public boolean packageV2BlobIntoIMAGE(java.lang.String cameraPortName,
                                      byte[] imageV2blob,
                                      de.desy.tine.types.IMAGE destTineImage)

interprets an input array (aImageV2blob) as a Video System v2 data block (header plus possibly additional format header plus image bits). In case validity checking succeeds, the contained image information is wrapped into a VSv3 TINE IMAGE datatype for use with all other Java Video code parts. As a Video System v2 header does not deliver a good string to be used as VSv3 header camera port (mounting place e.g.) identification, this member in IMAGE datatype is taken from aCamPort parameter.

Parameters:

cameraPortName - camera port description to be put in resulting IMAGE aDestImage

imageV2blob - input data set (should contain VSv2 image data block)

destTineImage - TINE IMAGE datatype output

Returns:

• true - success
• false - error importing blob (most probably validity checking failed)

parseImageV2blob

public boolean parseImageV2blob(byte[] buf)

interprets an input array (buffer) as a Video System v2 header. In case validity checking succeeds, the contained image information is stored into local class variables.

Parameters:

buf - VSv2 header as byte array

Returns:

• true - success
  
• false - error, no class variable is updated (most probably validity checking failed)
