#10750: Tee muxer breaks DTS fixing
-------------------------------------+-------------------------------------

-------------------------------------+-------------------------------------
Summary of the bug:
When using ffmpeg to copy a stream which has some error in the DTS
ordering, normally this error will be fixed for that single timestamp,
result in a single warning and cause no further issues. E.g.
{{{#!bash
ffmpeg -i test.mkv -map 0 -c copy out.mkv
}}}
However, when doing the exact same thing but via the tee muxer
{{{#!bash
ffmpeg -i test.mkv -map 0 -c copy -f tee '[f=matroska]out.mkv'
}}}
all timestamps get broken and an offset is created in the file.
Tested with latest git version, as well as with current Ubuntu 22.04 and
Archlinux.
I will add an example file to test this with.
