Since the 4K version of Sintel is huge and almost impossible to find nowadays,
I made a shortened sample (with Avidemux, without re-encoding). Simply download
http://jeff.ecchi.ca/public/sintel-4k-torture-sample.mkv and try seeking it in
various places.

The typical seeking time with totem/pitivi on gst 1.x is 15 to 30 seconds.
VLC manages to have typical seeking times of 2-3 seconds (sometimes 4-5).
mplayer somehow manages to seek instantly (?!)

Core 2 Quad Q9300 CPU, no hardware decoding acceleration.
