Hi,

How could I show a variable Text overlay on video stream showing value obtained from a REST API?

 

Example... get sensordata from sensor via REST API and display as text overlay on video stream.

  Hello Harald,

  You could develop an analytics plugin, by using Metadata SDK, which would display a bounding box with attributes.

  One of the attributes could have a text value of sensor data. The bounding box coordinates could be set to make it look like a pixel-wide line.

  In version 4.2 there will be improvement in the rule engine.

  It will introduce a special syntax that would allow sending Event parameters in actions with customizable content (e.g., "Do http request", “Push notifications”, "Text overlay" actions)

  E.g. syntax like this:

  • {event.source}

  • {event.caption}

  • {event.description}

  • {event.timestamp}

  For your case would be possible to create a rule

  On Generic Event -> Show text overlay

  Then trigger generic event over API and provide sensor data in the event description field, for example
