-------------------------------------+-------------------------------------
 When executing the command "ffmpeg -i h264_bad_duration.mov", ffmpeg
 returns the below details. The important (wrong) part is Duration. The
 video duration is (roughly) 30 seconds, but ffmpeg shows it as 5:34.49. It
 does appear to play correctly in mplayer (though it reports the same wrong
 duration, which should be no surprise).

 File located at http://usmediavault.com/h264_bad_duration.mov

 I tried uploading to upload.ffmpeg.org, but was unable to.

 Thanks for looking at this.
