--- Comment #3 from Tim-Philipp Müller <t.i.m at zen.co.uk> ---
Can still reproduce this with totem-video-thumbnailer. Bit baffling.
Problem is that we can't get a sample/buffer via the last-sample property
because the video sink has prerolled from a GAP event.
It looks like a GAP event was sent by stream synchronizer because the other
stream (audio) got an EOS. Why the audio stream got an EOS, I don't know, we're
doing a seek to 1.947 secs and there's 5.8 secs of data for both streams.
This might be a clue:
<qtdemux0:sink> pullrange failed
I think there's something wonky with some of the atom sizes. mp4info also
throws some warnings.
I don't understand yet though why this is only triggered by a seek and not when
just playing the file.
Needs more investigation, but qtdemux looks like the culprit for now.
