 Summary of the bug:
 Seems new ffmpeg versions does not work with -ss switch on DAV files
 input. It does work properly with MP4 file as input. FFMPEG just ignore it
 and cut from beginning of file. I also checked older version "ffmpeg
 version 4.2.2 Copyright (c) 2000-2019 the FFmpeg developers" and it worked
 properly. The "-t" switch worked ok on every version.

 How to reproduce:
 {{{
 % ffmpeg.exe -ss 01:00 -t 01:00 -i "file.dav" file.mp4
 ffmpeg version 4.4-full_build-www.gyan.dev Copyright (c) 2000-2021 the
 FFmpeg developers
 built with gcc 10.2.0 (Rev6, Built by MSYS2 project)
 and
 ffmpeg version n4.4-80-gbf87bdd3f6-20210819 Copyright (c) 2000-2021 the
 FFmpeg developers
 built with gcc 10-win32 (GCC) 20210408
