I read the mpv man page and found a solution.


Create a file ~/.mpv/input.conf with the content

i show-text ${estimated-frame-number}

When playing a video you can now press the i-key to see the 
current framenumber. 

But manpage says about the estimated-frame-number property: 
"This is only an estimate. (It's computed from two unreliable 
quantities: fps and possibly rounded timestamps.)

I've tested it with some videos that I recorded with my 
smartphone and it seemed that the printed frame number was 
always correct.


Another thing that it maybe useful:

If you start mpv from command line with these two options 

--osd-level=3 --osd-fractions=yes

then the OSD as well as the console output shows you the 
current timestamp with milliseconds.

If you don't wanna start mpv from command line then you can 
also add these two options to ~/.mpv/config 
If you do this you need a line for every option and you may 
not include the double hyphens.


Btw.: If you press the . key while playing a video, mpv will
switch to single frame mode. Every time you press this key 
again, mpv shows the next frame. 
You can use the space bar to continue/pause the video.
