Description (last modified by )
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.
ffmpeg -i test.mkv -map 0 -c copy out.mkv
However, when doing the exact same thing but via the tee muxer
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.
You can find a small example file attached.
