That's what I thought, that it should not matter.  I nevertheless asked
Bitwig.

I know, but the idea here was do first check if the new libav/ffmpeg
would by OK by themselves.  I presume I could go the configure way
now.  But, the picture is not so clear since the /usr/local/ location
should not matter (ldconfig was run and the avplay for instance is
available w/o specifying the path) and Bitwig still does not play right
the test file.

Hmmmm... This I am not keen about.  After years and years of building
Linux systems from scratch (LFS, BLFS) for both home and work, I am
using now a packaging system that's provided by the OS because it's
convenient but I still think that maintainers do absurd links, the
typical one being adding emacs in the dependencies because there is a
lisp file in a package.

Likewise, removing stuff does not forebode good tidings.  I guess I
could do a dry run.  And I could look at the control file.

Or I could use configure with /usr/
