When a matroskademux src pad is relinked (because the old one was removed), the
probe that corrects the segment start is lost with the disappearing pad and
never reinstalled on the replacing one. This can cause issues, for instance,
while doing trick playback in reverse on Broadcom devices, which don't need
parsers.
During trickplay, pads between demux and appsink elements are relinked.
GstBuffers related to trick playback are rejected/clipped by appsink (more
precisely, by its base class: GstBaseSink), because GstSegment start position
value don't match to those GstBuffers.
