Playing MP4 files

ATM am trying Video Inspector, but am unable to load the MP4 file on my desktop for inspection

Suggestions?

 

How do I get Picasa showing MP4 videos?

My research suggests that in order to get MP4s visible in Picasa (on Windows 10) I need to either install QuickTime or a codec pack.

Both options aren't particularly appealing (for security and stability reasons).

Is there another way to get MP4 videos displayed in Picasa?

(Changing photo software isn't an option)

 

Playing MP4 files

MP4 is a container file, a lot depends on the codecs within that.
MP4 can be played with Windows 10 with Films & TV, Photos, Windows Media Player, and VLC.
If those can't then there must be something odd/unusual in the file.

Right click the File > Properties > Details Tab.
see if that gives you more info, should be some info on the video/audio but not codecs.

Try the suggestions from post #3.

You have to be careful as viruses are propogated by people simply changing the filename extension and auto-forwarding via an infected PC and a compromised address list.
So a targeted scan with AV is necessary for every file attachement even if apparently from someone you know.
