Summary
(Not super technically savvy, so I apologise)
After attempting to import certain MP4 files I've found Olive either outright crashes (not offering a crash report or subsequent menu, simply just closes) or claims the file is unsupported (only in one instance, of the 4 files I'm trying, 3 cause crashes with no subsequent information). I've successfuly loaded some MP4s I know have worked in the past, but as soon as I try to import one of the files causing crashes, a crash occurs every time. I have check the properties of the problem files and confirmed everything is in order, the only correlation I can find is that the problem files have no thumbnail and only show the VLC icon. I don't know if that even means anything to this issue.

Steps to Reproduce

1. Create new project
2. Import Mp4 file that lacks a thumbnail via any means (drag-drop, import menu, etc.)
3. Either Olive crashes or claims the file is not a compatible format

Crash Report (N/A)
