[FFmpeg-user] Wrong Duration

[Yugant Khanna]

Hi ,
I have uploaded one .mxf file at the following url

https://www.wetransfer.com/downloads/5880b625772f746b35779d067ea4091d20130902081204/2c99ae37db1b272095a1b607c867282c20130902081204/aba1e7


The issue is when i use FFMPEG / FFPROBE to get the duration of the .mxf it
shows 00:02:10.48
wheras the actual duration of the file is 5 secs only. You can doesnload
the file from the above url

At least one output file must be specified

Even if i use the ffprobe , still it gives me the Duration as 00:02:10:48.

Wheras the actual duration os the file is 5s 0ms .  I reched it with Media
info and VLC player it's 5 secs only
