Can't playback this MP4 package file

Hi all, I grabbed this file from a web TS stream (offered by Vimeo), but can't play it with Foobar2000 directly.

It says "invalid or missing mvhd data"

I can either
- play it via any video player or even browser;
- easily convert it losslessly using FFMPEG to standard M4a or similar and play it just fine

But what I'm curious is if it's possible to play it directly with Foobar2000, i.e. if there is anyway to make fb2k to be able to decode this kind of package (iso5 (iso6/mp41)?), because AFAIK Foobar2000 can already decode most of common packages (like mp4, m4a, mka, mkv...) except this one.

By "package" I mean "container", sorry about that!

This file has duration fields filled with nulls instead of valid duration. Though it's otherwise readable and the missing data is easily recalculated.
Fixed for the next update, thanks for reporting.
