Schema
The output of the handler provides the following attributes as a schema. Attributes can be in arbitrary order and will be identified by the type.
| Name | Type | Description | |||
|---|---|---|---|---|---|
| image | IMAGEJCV | The current frame of the video stream | |||
| starttimestamp | STARTTIMESTAMP | The start time stamp of the frame. Depends on the timestampmode option, will be omitted when set to 'none' | endtimestamp | ENDTIMESTAMP | The end time stamp of the frame. Depends on the timestampmode option, will be omitted when set to 'none' |
Example
This example shows how to grab a video from a webcam basler camera and display it in a window:
...
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
video = ACCESS({source='Video',
wrapper='GenericPull',
transport='noneBaslerCamera',
protocol='OpenCVVideoStreamnone',
datahandler='Tuple',
options=[
['streamUrlserialnumber', 'camera://021448278'],
['timeStampMode', 'none']
],
schema= [
['image', 'IMAGEJCV'],
'IMAGEJCV ['timestamp', 'STARTTIMESTAMP']
]})
/// or shorter, as a source operator:
video = OPENCVVIDEOBASLERCAMERA({source='Video', options=[['streamUrlserialnumber', 'camera://0'], ['timeStampMode', 'none21448378']]})
output = UDO({class='ShowImageJCV', init='0,Video'}, video) |
