[aac @ 0x10d3c40]This encoder does not yet enforce the restrictions on LFEs.
The
output will most likely be an illegal bitstream.
Output #0, mp4, to 'test.mp4':

=========================================
as you can see at the end it says time=6.04
when the test.mp4 is played it plays for 8 seconds.
here is the same video converted to yuv this time.

==============================================
now it reports time=26.23
as you can see same exact video, two different times
=====================================================
problem can be replicated by downloading any video trailer
from apple.com and then modifying it with quicktime on an imac
use quicktime's "trim to selection" feature to chop the video
and test it.
=========================================================
i am also including the file "test.mov" so you can test it
yourself. ( test.mov is from apple.com/trailers
i trimmed it with quicktime"
you can also run ffmpeg -i test.mov
and here's what it shows...
===========================================================
ffmpeg -i test.mov

At least one output file must be specified
================================================================
as you can see the DURATION is incorrect.
