Comment:

 If you need accurate seeking, please use -ss as an output option. See
 https://ffmpeg.org/ffmpeg.html#Main-options

 This command gives me the correct images:

 {{{
 for i in 0.88 0.92 0.96 1.00 1.04 1.08; do ffmpeg -i myVideo-
 bugReport-4554.mp4 -ss 00:00:0${i} -frames:v 1 sec${i}.jpg; done;
 }}}

 sec0.88.jpg -> 14:53:07:12
 sec0.92.jpg -> 14:53:07:13
 sec0.96.jpg -> 14:53:07:14
 sec1.00.jpg -> 14:53:07:15
 sec1.04.jpg -> 14:53:07:16
 sec1.08.jpg -> 14:53:07:17
