Seeking is not going to help you much indeed. The best for removing
silence from a stream would be to write an element that analyses the
audio and drops any audio that is considered silence. It could
optionally also offset the following timestamps to make it appear as if
nothing was dropped.

Doing this based on GstBaseTransform should be relatively simple.


(Same goes for your other question about splitting on silence, you need
something that detects silence and then does something about it)
