> So let's say I want to copy streams (without transcoding) in another
Matroska file. That is the same command line except you replace {{{md5}}}
by {{{matroska}}}, and stdout by a filepath. How is that different?
It isn't, it can fail for some files depending on your configure options.
Please understand that this isn't necessarily the case for your example in
this ticket (your bisect will show once you try it as suggested below), I
just want to explain to you that imo your whole process is flawed (at
least with the configure line you are apparently using) because it will
fail for some examples. And I am not convinced that a demuxers output is
''specifed'' the way you seem to believe it is (and the way you test it).

that behave the same) as {{{bad}}} and n2.2.7 (and all revisions with the
same output) as {{{good}}}? This is the only way {{{git bisect}}} works
and it will show you the commit that introduces the change.
> Yes I know how git bisect works. That is what I did.
Funny that your output shows that you tried something different that
cannot work (and this has nothing to do with FFmpeg).
