Comment (by Rapper_skull):
Update:
I also tried the bash inline syntax ''ffmpeg -i <(cat test.m2ts)'', but
the timestamps are still wrong.
I tried to use the concat protocol as described
[https://trac.ffmpeg.org/wiki/Concatenate here], but unfortunately there's
a bigger issue: starting from the second file all timings are wrong (at
the end I get a 5 seconds difference).
This problem is present even if I manually join the files with ''cat'' and
then use the result as an input. The only way is to resort to the trick of
autputting the video to /dev/null. Even ''-fix_sub_duration -copyts
-start_at_zero'' does nothing.
