Extra mp4 header data causes decode failure

[cgbug]

Sample:
​https://www.datafilehost.com/d/3dcb324d

Sample contains original video file, and modified file after import from a mobile phone by Windows. The only difference is some extra metadata in the header (a date of import value). Hex comparison picture is included as well.

Which software allows to read the broken file?

[cgbug]

I haven't found anything that can play it. I also did not make the file. Strictly speaking it probably violates spec. But looking at the hex diff, that unknown header element could just be ignored / skipped over.

I don't think this is a valid ticket, feel free to reopen if you find a software (or hardware) that can read this file.
