I'm aware of that, but thanks for pointing it out anyway. ;)

Now that it's been decided to drop the libav source package after the
transition, we could do this, but the question is, whether we should.
I've asked for feedback about that [1]:
"Though I'm wondering now, if it wouldn't be better to also take over the libav-tools
binary package (instead of the libav-tools-links package), so that existing
installations of libav-tools get migrated to ffmpeg.

The libav-tools-links only 'Provides: libav-tools' so that dependencies can be satisfied,
but since apt prefers real packages over virtual ones, it wouldn't affect existing
libav-tools installations.

What do you think?"

The thing is that last time people didn't like to get the libav tools, when
they had installed ffmpeg...

In any case, this does not have to be entangled with the library transition.
