--- Comment #3 from Tim-Philipp Müller <t.i.m at zen.co.uk> ---
Intel(R) Core(TM) i7-4702HQ CPU @ 2.20GHz, decoding with gst-libav.

Key-unit seeks:
100 seeks, min: 95ms, max 332ms, avg 220ms

Accurate seeks:
100 seeks, min: 157ms, max 2912ms, avg 1039ms

The file is 23 seconds long and has 5 cue entries. The first and second index
entry are 10 seconds apart.

I'm a bit confused because the bug title talks about this being a PNG file (and
it's what I remember too), but the file I just downloaded from the link has in
fact H.264.

Either way, it's not clear to me there is anything outrageous happening here
any longer.

Can we close this, or was this about a different file after all?
