Jitterbuffer's buffer mode performs buffering by simulating a PAUSE using
timestamp offset (in concert with rtpbin). The ts offset is needed as it is
only a simulation since PLAYING state is maintained, and as such running time
continues to increase. Consequently, position reporting (derived from running
time) also increases while buffering is ongoing (and also off the mark when
resuming). This is particularly confusing for buffer mode's primary use case,
i.e. non-live material (where position has a very specific meaning).
Unfortunately, jitterbuffer's slave mode (still?) does not handle bursts well,
unless there is some room for tweaking there ...
