Description
http://assets.eleven45.net/testing/ffmpeg-bug/5-sec-last-frame.gif
Summary of the bug:
When converting an animated GIF to video (I'm using h264 yuv420p) with a filter, the duration of the last frame is lost.
How to reproduce:
Consider this animated GIF: http://assets.eleven45.net/testing/ffmpeg-bug/5-sec-last-frame.gif (also attached)
It has 6 frames. The first 5 are 0.2s and the last one is 5s.
Without filters, the output video has the expected duration (5x0.2s + 5s = 6s):
$ ffmpeg -f gif -i 5-sec-last-frame.gif -pix_fmt yuv420p -c:v libx264 -report out-without-filter.mp4 $ ffprobe out-without-filter.mp4 2>&1 | grep Duration Duration: 00:00:06.00, start: 0.000000, bitrate: 26 kb/s
With filters, the output video has the wrong duration (1.2s):
$ ffmpeg -f gif -i 5-sec-last-frame.gif -pix_fmt yuv420p -c:v libx264 -vf scale=300:300 -report out-with-filter.mp4 $ ffprobe out-with-filter.mp4 Duration: 00:00:01.20, start: 0.000000, bitrate: 87 kb/s
The last frame should have a duration of 5s, but it's getting a duration of 0.2s from somewhere.
This is a problem because I am looping these videos as a replacement for animated GIFs.
I have reproduced this bug on many versions of ffmpeg, but all the information in this issue was from the latest snapshot/dev version, as seen in the output.

I created the input file as a clean test image using Photoshop 2020, which is attached.
I've also attached the full report from both scenarios (with and without filters) and a diff.
