The following XML is a single record produced during barcode analysis:
<record>
...
<trackname>barcode.Result</trackname>
<BarcodeResult>
<id>b8c4331e-6058-4786-83d9-a43e605f463e</id>
<text>some text</text>
<barcodeType>Code-128</barcodeType>
<region>
<left>94</left>
<top>66</top>
<width>311</width>
<height>98</height>
</region>
</BarcodeResult>
</record>
The record includes the following information:
The id element provides a unique identifier for the detected barcode. The barcode analysis engine issues an ID for each detected appearance of a barcode. If you are detecting barcodes in video and consecutive frames show the same barcode in a near-identical location, all records related to that appearance will have the same ID.
For example, if a barcode appears in the same location for fifty consecutive video frames, the engine uses the same ID for each record in the data track and produces a single record in the result track. The record in the result track will have a timestamp that covers all fifty frames.
If the barcode moves to a different location on the screen, or disappears and then reappears, the engine considers this as a new detection and produces a new ID and a new record in the result track.
text element contains the data encoded by the barcode. If HPE Media Server detects a barcode with a supplement, for example EAN-13+EAN-2, the text element contains the digits from both parts of the barcode, separated by a hyphen.The barcodeType element contains a string which describes the type of the detected barcode. This can be any of the following values:

region element describes the position of the barcode in the ingested media. If HPE Media Server detects a barcode with a supplement, for example EAN-13+EAN-2, the region includes both parts of the barcode. |
