SS switch not working with DAV format

[Michal]

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

Hello, problem is that I have only output from Video Recorder which is 278 MB large and I don't know how to split this file ( ffmpeg only allow to convert it not just cut / split ). Any idea how I could do it? If You want I can give You privately this whole video on onedrive for example.
