How to do lengthy processing in an element

Fri Dec 9 10:05:13 UTC 2016

It is a one shot task that I need to execute.
The element analyzes video frames and once it has accumulated enough samples it needs to do a one shot computation that can take several seconds to complete.The result of the computation needs to be fed back into the element.

That's more for one-shot, simple tasks that don't take are not
continuously running. Like if you have to do some action on your
element from a non-streaming thread.

For long-running tasks that are just the element processing, you should
consider starting a new thread.
