Its not neutral if one submits patches to one project but
not the other.
Thats pretty much the definition of neutral vs. non neutral.

yes, it is a matter of 2 seconds to add ffmpeg-devel to the CC of
Seperate patches that are based on ffmpeg and are fully tested
might be a bit more work but then that makes sure they have been
tested and work in ffmpeg, and thats very important!

duplicate review as in "more people reviewing code" doesnt sound like
a bad thing to me.
> ---> duplicated work on fixing things
if 2 sides ask you to fix the same thing its still just one time that
you need to fix it. If only one side asks you to fix an issue then
imagine you didnt sent it to that side, it would have a unfixed bug
in that case.

other developers submited patches to both projects and that didnt
also consider the kernel
"Unless you have a reason NOT to do so, CC linux-kernel at vger.kernel.org."
same applies to ffmpeg pretty much, if you have a patch that makes
sense for ffmpeg, CC it to ffmpeg-devel. Dont just send to libav
debian, gentoo, mplayer, vlc or whatever.

More bugs/issues might be found and it might be thus more work
fixing them but thats what reviews are for, finding and fixing issues.
