Major dependency problems while installing libav-tools / ffmpeg / libavcodec55

Hello,

although the codec system is perfect on Saucy and actually does not require ffmpeg at all, the thing is, once you start converting videos or ripping audio from video, you DO require ffmpeg.

Unfortunately, here on Saucy dependencies do not match AT ALL currently. And even though I could fix things by installing "unstable" packages using dpkg, I think putting up this question will also help others accomplish things OOTB.

Let's start:

- ffmpeg dependencies are:
(1) libavcodec55
(2) libavdevice55
(3) libavfilter3
(4)libavformat55

(1) libavcodec55
Sub-dependencies are:
a) libopus0 (>= 1.1~beta) -- CAN'T DO -- Latest on saucy is 1.0.1-0ubuntu2
b) libva1 (> 1.2.0~) -- CAN'T DO -- Latest on saucy is 1.1.1-3

(3) libavfilter3
Sub-dependencies are:
a) libavcodec55 (>= 10:2.1.1) -- CYCLIC DEP. see (1) --
b) libavformat55 (>= 10:2.1.1) -- CYCLIC DEP. see (4) --
c) libfontconfig1 (>= 2.11) -- CAN'T DO -- Latest on saucy is 2.10.93-0ubuntu1

(2) libavdevice55 + (4) libavformat55
Sub-dependencies are all cyclic and have already been mentioned.

This is all very awkward. Too high version numbers required by the install system are bringing things to a full halt.
I think if aptitude demanded a previous version of some of (1) to (4), things would work OOTB. However, currently all seems messed up.

How did you guys solve this problem *without* applying ugly DIY kludges like risking to make your system unstable by installing unsupported packages that do met deps? (I'd rather refrain from doing that)
