Retrieving bad duration from h264 mov file

Description (last modified by cehoyos)

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.
