Dynamic Replacement of a source element in pipeline

[Pascal Jacquemart]

Ok but it does not make sense to set 0 as pad offset
You should set the offset as the running time of the pipeline instead

Otherwise, if it does not work, you might be able to use the
input-selector element. This element has some capabilities to
synchronise various inputs to the same running time.
