I am unable to get ffmpeg to calculate PSNR for any video files.

Reed Crowe-3
I have tried this test with three different versions of ffmpeg (4.3.1,
3.4.8 and N-100671-gc48110a4a4  on 2 different OSes (Ubuntu 18.04, Fedora
33).

Here is the command I am using:
ffmpeg -i 17647_20210118_195325.mp4 -i test.mp4 -filter_complex psnr -f
null -
These are the same file (one just renamed). But I have tried it with
different files as well with the same error. I'm not totally sure what the
error means.

Error: Application provided invalid, non monotonically increasing dts to
muxer in stream 0: 748 >= 748

Output with errors:

The output (encoding) time base is, by default, set to the reciprocal of
the frame rate.  When converting from a finer input time base, 90000 in
this case, may produce collisions. So let's keep the input tie base. Add
-enc_time_base -1

However, this does not interfere with PSNR calculation. See below.

PSNR is calculated and printed on the last line above.

Still does not work.
With this command:
ffmpeg -i /home/rcrowe/LVT/17647_20210118_195325.mp4 -i
/home/rcrowe/LVT/test.mp4 -enc_time_base -1 -filter_complex psnr -f null -
I get the same results:

When I try a different file, (different camera) I get a slightly different

either.

Gyan,
Wow, thank you for that. I had no idea what inf meant. I just assumed it

I appreciate you taking the time to help me out.
Thank you.
