Program to perform a seek on a given URI after 10 seconds

When using gst-player to play a flac track from an http server, seeks take a very long time (10s of seconds upwards). This is not seen when playing from a file.

This behaviour is a regression from 1.10.5. Reverting adeee44b07a173b9ab4253216caba8f66dd43abb (fix for bug 727802) makes seeking work in a more timely fashion again.

A simple program using gst-player to play a URI and perform a seek after 10 seconds is attached. The file I've been testing with can be downloaded from http://upgrades.uuvol.com/alanis.flac

My guess would be that it's also draining then and does not honour the flush flag in the seek, if that commit indeed makes a difference. Needs some debugging and looking at logs though to see what it actually does while "doing nothing".

Attached a log with GST_DEBUG=5.

The seek happens after 10 seconds, and is a seek to 30 seconds into the track. No audio is heard for more than a minute after the seek (at which point I stopped).
