[gst-devel] New segment update

[ved kpl]

Why use two pipelines?, You can use queue2 with use-buffering == TRUE
and appropriately set the low and high thresholds.
Whenever the pipeline hits low threshold, set it to paused (waiting
for the queue to fill up) and then accordingly set the pipeline to
playing.
Listen for the buffering percent messages onto the bus to achieve this
and also fine tune your high and low thresholds for the queue.
