The file is 5.3 GB large.

smaller files that i tried working.

Messages suggest the file is shorter than 1667.46 seconds.
Given the fact it’s 5.3 GB large - the file is either corrupted or
there is something in it which confuses nginx. Could you please
provide debug log and the file for investigation?

Ok, debug log suggests that there are 4 tracks in the file, and one
of them is just 0.8 seconds long:

2012/07/17 19:01:26 [debug] 4539#0: *10 tkhd duration:4208128,
time:7013.547s

2012/07/17 19:01:26 [debug] 4539#0: *10 tkhd duration:4208140,
time:7013.567s

This is what causes your problem, as nginx isn’t currently able to
drop short tracks, only seek them all. And nginx complains as one
of the tracks is too short for a requested seek.

This should be handled better.

Maxim, if you send me an eMail, i will give you a link to the video.

Actually, my email is included in all messages to the mailing
list (though forum interface hides it). See e.g. here:
