The video File:Republica 2013 - Ai Weiwei.ogv on commons does not play when using both |start= and |end= parameters, sample:
[[File:Republica 2013 - Ai Weiwei.ogv|thumb|Interview with Ai Weiwei ...|upright=1.25|start=3:46|end=14:53]]
on http://en.wikipedia.org/w/index.php?title=Ai_Weiwei&oldid=561895502#Life_and_work . The video is not shown and the error message reads: "Error creating thumbnail: Invalid thumbnail parameters or image file with more than 12.5 million pixels"

This worked fine previously and still does on de.wiki: http://de.wikipedia.org/wiki/Ai_Weiwei#Leben

It works for me on en.wiki if I remove either the start or end parameter.
