I am implementing dynamic parameter control for the following pipeline:
uridecodebin ! videoconvert ! my-filter p=1 ! fakesink, which is playing a
single video file in a loop using segment done callback from the pipeline's

Folllowing the Dynamic Controllable Parameters tutorial (,
I  added parameter control using GstInterpolationControlSource.

The control binding uses running time, whichh iin my case is  the video's
position. I would like to use absolute-time instead to allow control of my
filter's parameters over multiple loops.

1. Is there a way to use absolute-time instead of running-time with the
2. If not, what would be the best way to make  the pipeline's running-time
be be monotonically increasing?

Thanks !
