Pipeline component for seeking?

  Hi All,

I'd like to know if there is a pipeline component that can be used to 
skip/trim/discard from the beginning of a media stream, (either a period 
of time or number of buffers)?  (something like 'tail' command with -n +NUM)

It's just for a quick test: no need for efficiency.

I tried:

gst-launch-1.0 \
     filesrc location="${file}" ! \
     qtdemux ! \
     avdec_h264 ! \
     progressreport update-freq=1 ! \
     output-selector name=o ! \
     fakesink num-buffers="${buffers}" \
     osel. ! playsink

hoping that the output-selector would select output zero (fakesink) 
until it goes eos then send to output 1, but no joy. (It's the first 
time I've played with output-selector, so may be a way to get it to 

I found a fallbacksrc, but I want a fallback sink I think for this approach!

Any ideas appreciated!
