I the seek position exist in your current available adapter data, then clip the
required amount of data and continue. If not, flush the adapter and pull the
data you need (in byte offset) from your source. If in push mode, convert the
time seek into byte seek and forward to your source (again flushing the
adapter).

For non-flush seek, playback what is in your adapter first, and then operate the
seek.
