Comment (by John Livingston):

 I have the same bug, with the git master branch version (2022-03-02:
 N-105822-g4b72bca6ca).
 Using `ffmpeg -i input20220302.mp4 output.mp4`, and opening the files with
 VLC (or any other player):
 - input file duration is 2:09
 - output file duration is 4:18

 Here is the report file generated by ffmpeg:
 https://trac.ffmpeg.org/attachment/ticket/6832/ffmpeg-20220302-172323.log

 I can provide the video file if needed (or you can get it yourself, its an
 import from Dailymotion using youtube-dl: youtube-dl
 https://www.dailymotion.com/video/xaj3ck )
