Yeah, I hadn't tried that before either.  I was a bit surprised.

And/or maybe just "file *" in the directory?

[egreshko@meimei tippy]$ file *
20181016_113143.mp4: ISO Media, MP4 v2 [ISO 14496-14]

I suppose that's useful to verify that it really is a .mov file, but my point 
is to find
out what codecs are being used.

Good point.

I tried a .move file that was a video I took with my digital movie camera, using both vlc and cvlc (which I think came from negativo17) and the movie played fine but the audio was garbled. I couldn't test the video in mplayer as the install of that wanted to remove a whole host of files that I didn't want removed, including vlc. I did try the video with what I think is Totem Movie Player (at least that is what the manual indicates when I select help from the menu) and both the movie and audio played fine.

The ffprobe output is below if that is useful.
