ffprobe 2.6.2 fails to fetch information from specific video file

[Mike Schekotov]

I am trying to fetch information from video file using ffprobe 2.6.2, but it fails, while old version (0.10.12) works like a charm.

File causing error: ​http://www.datafilehost.com/d/46bc7bae

ffprobe 0.10.12:

% ffprobe -v 9 -loglevel 99 error_on_ffprobe_2_6_2.mp4
