Why do you want to or need to control that?

Could you provide some more context about what you're trying to achieve
exactly? (big picture)

What kind of source element is it? (audio, video, something else)

Is it a live source? Where does your data come from? Can it be produced
on demand or do you have to wait for it or is it produced in regular
intervals (e.g. at X fps)?

The create method will typically be called whenever a new buffer is
needed, which is typically when downstream (transform ! sink) are done
with the previous buffer and give control back to the source. Assuming
there are no queues in between.

Cheers
 Tim
