The file info seems normal. Just to check that it’s not about one bad file (from your question it seems like you’ve only tested one file - maybe it’s more): can you play any other kind of videos - like .avi, .mkv or from net (like youtube)? And is this file on the eMMC (/home), SD card, USB-stick or from a network source (wifi, mobile or wired)? If you can test some of those, that would rule out some reasons (like a weird bad file, bad file system/partition/disk, or long download of an online video source).
