Hi,

during a test with piuparts I noticed your package fails to co-install
with libav-tools from wheezy.
libav-tools installed fine in 'wheezy', then the upgrade to ffmpeg/'sid' fails
because it tries to overwrite other packages files without declaring a
Breaks+Replaces relation.

See policy 7.6 at
https://www.debian.org/doc/debian-policy/ch-relationships.html#s-replaces

>From the attached log (scroll to the bottom...):

  Selecting previously unselected package ffmpeg.
  Unpacking ffmpeg (from .../ffmpeg_7%3a2.5.4-1_amd64.deb) ...
  dpkg: error processing /var/cache/apt/archives/ffmpeg_7%3a2.5.4-1_amd64.deb 
(--unpack):
   trying to overwrite '/usr/share/man/man1/ffplay.1.gz', which is also in 
package libav-tools 6:0.8.16-1
  dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)
  Errors were encountered while processing:
   /var/cache/apt/archives/ffmpeg_7%3a2.5.4-1_amd64.deb

Since there is no ffmpeg package in jessie, adding these Breaks+Replaces
would ease some upgrade paths from wheezy as well as possible backporting.

In libav (6:9~beta1-1) the compatibility links for ff* tools were removed.


cheers,

Andreas
