|

|
* Detect bar codes in the video streams and send them as element messages to
|
||||||
|
* the #GstBus if .#GstZXing:message property is %TRUE.
|
||||||
|
* If the .#GstZXing:attach-frame property is %TRUE, the posted barcode message
|
||||||
|
* includes a sample of the frame where the barcode was detected (Since 1.18).
|
||||||
|
*
|
||||||
|
* The element generate messages named `barcode`. The structure contains these fields:
|
||||||
|
*
|
||||||
|
* * #GstClockTime `timestamp`: the timestamp of the buffer that triggered the message.
|
||||||
|
* * gchar * `type`: the symbol type.
|
||||||
|
* * gchar * `symbol`: the detected bar code data.
|
||||||
|
* * #GstClockTime `stream-time`: timestamp converted to stream-time.
|
||||||
|
* * #GstClockTime `running-time`: timestamp converted to running-time.
|
||||||
|
* * #GstSample `frame`: the frame in which the barcode message was detected, if
|
||||||
|
* the .#GstZXing:attach-frame property was set to %TRUE (Since 1.18)
|
||||||
|
*
|
||||||
|
* ## Example launch lines
|
||||||
|
* |[
|
||||||
|
* gst-launch-1.0 -m v4l2src ! videoconvert ! zxing ! videoconvert ! xvimagesink
|
||||||
|
* ]| This pipeline will detect barcodes and send them as messages.
|

|
* |[
|
||||||
|
* gst-launch-1.0 -m v4l2src ! tee name=t ! queue ! videoconvert ! zxing ! fakesink t. ! queue ! xvimagesink
|
||||||
|
* ]| Same as above, but running the filter on a branch to keep the display in color
