ffplay fails to take into account -t and -autoexit at the same time

[Théo]

When trying to display an image for a set period of time and exiting after it's done instead of getting the image for a set period of time and exiting it, exit immediately.

How to reproduce:

ffplay -t 5 -autoexit denial_everywhere.jpg
Input #0, image2, from 'denial_everywhere.jpg':

Workaround: Use -loop 125 instead of -t 5. The default framerate is 25.

Hey, thanks for the workaround but do you know why it would only work with .png image and not .jpeg ? For example :

time ffplay -autoexit -loop 625 adamdenial.png
ffplay -autoexit -loop 625 adamdenial.png  19,93s user 1,89s system 66% cpu 32,778 total

time ffplay -autoexit -loop 625 adamdenial.jpg
ffplay -autoexit -loop 625 adamdenial.jpg  0,25s user 0,16s system 5% cpu 7,029 total

I don't know why it doesn't work with jpg images. But I'm quite sure that it did work some time ago.

It does also work with jpg images, but the framerate seems to be much faster:

This shows the image for about 3 seconds:
ffplay -autoexit -loop 300 spectrum.jpg

This shows the image for about 22 seconds:
ffplay -autoexit -loop 300 spectrum.png
