I thought about that, too, but then the pipeline doesn't work if there
is any element after tarenc that doesn't support seeking, i.e.
bz2enc :-(

I was wondering if I should write an extra element (or enhance GstPad?)
that buffers lots of data automatically if elements before it advertise
somehow their need to seek and elements after do not support seeking...
