package libavfilter-unstripped-0 None [modified: /var/lib/dpkg/info/libavfilter-unstripped-0.list] failed to install/upgrade: tentative de remplacement de « /usr/lib/libavfilter.so.0.2.0 », qui appartient aussi au paquet libavfilter0

that's correct. the control file is missing propoer conflicts/replaces.

adding to my git branch, will be part of the next upload. thanks for reporting this issue!

This bug was fixed in the package ffmpeg - 3:0.svn20090204-2ubuntu1+unstripped1

---------------
ffmpeg (3:0.svn20090204-2ubuntu1+unstripped1) jaunty; urgency=low

  * rebuild using a clean, uncrippled ffmpeg tarball

ffmpeg-debian (3:0.svn20090204-2ubuntu1) jaunty; urgency=low

  * merge from debian. Remaining changes:
    - don't build depend on libfaad-dev

ffmpeg-debian (3:0.svn20090204-2) experimental; urgency=low

  * add libxvmc-dev to build-depends in the 'ffmpeg' variant
  * add libasound2-dev to build-depends. This means that ffplay is now able to
    actually play using alsa directly instead only via libsdl
  * add epochs for the "internal" shlibs dependencies

ffmpeg-debian (3:0.svn20090204-1) experimental; urgency=low

  [ Reinhard Tartler ]
  * New Upstream Version (svn revision 16978 libswscale revision 28461)

  Upstream Changes:
    - R3D REDCODE demuxer
    - ALSA support for playback and record

  * strighten internal dependencies by using a shlibs.local file
    Closes: #512844, #512466
  * New upstream version reintroduces a compatibility symbol ff_gcd
    Closes: #512946
  * Bump shlibs because of changes of the Metadata API in libavformat.
    Actually no other package should use them yet, but let's better play safe
    here...
  * no longer install dsputil.h. It exposes lots of function that are private
    to ffmpeg and may change on any new upstream revision. Please get in touch
    with the ffmpeg maintainers if you maintain packages that rely on that
    ffmpeg internal headers like this.
  * simplify debian/confflags by doing autodetection of headers:
     - xvid.h
     - lame/lame.h
     - faac.h
     - x264.h
     - vdpau/vdpau.h
    Also remove the setting externalcodecs from DEB_BUILD_OPTIONS. The codecs
    will be enabled as soon as the headers are installed on the filesystem,
    so there is no need in enabling that separately.
  * install ffpresets in /usr/share/ffmpeg/. Currently only presets for
    x264 are avaiable, so a libx264 enabled libavcodec (like
    libavcodec-unstripped-52) is needed to actually use them.

  [ Fabian Greffrath ]
  * Enabled Speex decoding via libspeex.
  * Use an alternative approach to achieve strict internal dependencies
    by calling dh_makeshlibs twice in debian/rules instead of a
    debian/shlibs.local file.

ffmpeg (3:0.svn20090119-1ubuntu1+unstripped2) jaunty; urgency=low

  * add conflicts/replaces on libavfilter0. LP: #323789

reopening. I still see this even with the package that was supposed to fix this -> bug 339436

I still had to manually deinstall libavfilter0
