Comment (by feelart):

 }}}

 You'll hear 6 sec(SIX) of audio, then loops after these 6 sec (well it
 happens because it's a cut of a NON corrupted mov, but ffmpeg doesn't
 properly close the stream; CLI "ffmpeg.exe -t 6 -i "2011-01-28 Salsa2.mov"
 -acodec copy -vn loopBug20130216COR.mov")

 So that my first post was incorrect in the reproducability, but not in the
 bug.
 In trying to cut the original file(700Mb) to fit in your 2MB limit( by the
 way, would be nice to raise limit to 8Mb), I first did a mistake in
 isolation, sorry.

 ffmpeg.exe -t 3 -i loopBug20130216COR.mov outMP3.mp3
 }}}

 {{{
 ffplay outMP3.mp3
 }}}

 You'll hear that after 3 sec the audio loops, as if the audio stream is
 incorrectly closed, this seems like the fixing of bug 1435.

 Trying aac convertion leads to same bug.

 Correct test file is thus loopBug20130216COR.mov
