User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.100 Safari/537.36

Steps to reproduce:

Hi,
I'm having this error "No video with supported format and MIME type found" when I try to play a video.
In Chorme it plays it without any problem.

Actual results:

In the console I can see this:

Media resource file:///C:/Users/tarik/Desktop/video.mp4 could not be decoded. video.mp4

Media resource file:///C:/Users/tarik/Desktop/video.mp4 could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_METADATA_ERR (0x806e0006)

Details: virtual RefPtr<MP4Demuxer::InitPromise> __cdecl mozilla::MP4Demuxer::Init(void): Parse MP4 metadata failed

Expected results:

Firefox should have played this video like other browsers.

I posted this issue using Chrome browser and the video I've uploaded plays fine in the post above but it doesn't even show on Firefox :(

According to error log, it looks like mp4parse_rust fails to parse the metadata.
