I need to install the package ffmpeg because I am trying to install subsonic server on my new Ubuntu Gnome 14.04

When I try:

apt-get install ffmpeg

I get:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 ffmpeg : Depends: libavcodec54 (>= 7:1.2.5~) but it is not going to be installed or
                   libavcodec-extra-54 (>= 7:1.2.5~) but it is not going to be installed
          Depends: libavdevice53 (>= 7:1.2.5~) but it is not going to be installed
          Depends: libavfilter3 (>= 7:1.2.5~) but it is not going to be installed
          Depends: libavformat54 (>= 7:1.2.5~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I have tried
apt-get -f install ffmpeg
apt-get install --fix-broken
apt-get autoclean
apt-get autoremove

With no luck at all. I found a repository and added it to my sources via:
add-apt-repository ppa:jon-severinsson/ffmpeg

With still no luck. I found this question Is FFmpeg missing from the official repositories in 14.04? which led me to try this:

apt-get install libav-tools

which resulted in this:

I also have made sure my "Software & Updates" have all the proper repositiories checked off, namely all 4 on the "Ubuntu Software" tab, and all on the "Other Software" tab with the exception of the second one (Canonical Partners Source Code). I also have these checked off as well per instructions supplied on the page they lead to:
http://ppa.launchpad.net/jon-severinsson/ffmpeg/ubuntu saucy main
http://ppa.launchpad.net/jon-severinsson/ffmpeg/ubuntu trusty main

None of this works. How can I install ffmpeg? Or if I cannot install it, what do I need to install to replace its functionality?

  • Can you install the dependencies manually? – s3lph Apr 15 '14 at 11:47
  • @the_Seppi you mean dependencies such as libavcodec54? that doesn't work either. Or do you mean something else? – wardr Apr 15 '14 at 14:16
  • when I try to apt-get install avconv - this package is not found. – wardr Apr 15 '14 at 14:16
  • one more thing, I just fresh installed 14.04 today. THis was one of the first things I tried to install on it. – wardr Apr 15 '14 at 14:17

    The prblem is the "big split" between ffmpeg and avconv, that makes almost impossible to cleanly install the two. Maybe http://askubuntu.com/questions/373322/how-to-replace-avconv-with-the-real-ffmpeg-and-have-it-work-right can help. I really went the way of installing a static build, works like a charm in 13.10: http://askubuntu.com/a/373328/16395 – Rmano Apr 15 '14 at 14:43
  • okay I followed those directions, but where do I go from here? I simply just have ffmpeg in a directory ~/bin, ran the command ./ffmpeg and it just provides configuration methods, kind of like a man page almost. @Rmano – wardr Apr 15 '14 at 17:35

    Now you just have to install the package that uses it. Btw, for system packages, is better to put the executable in /usr/local/bin/. Each application will have a different way to find the ffmpeg binary --- I known nothing about subsonic. Moreover, some applications use the library and not the binary; in that case the static binary solution is not useful at all, you should try the other solution, but you're on your own. Debian and Ubuntu have chosen to go with libav, not with ffmpeg. Info here: https://bugs.launchpad.net/ubuntu/+source/libav/+bug/1263278 – Rmano Apr 15 '14 at 17:40
  • @rmano problem is I can't install libav either, I got errors on that too (see above). I ffmpeg will not install on 14.04 I've tried everything (I think). – wardr Apr 15 '14 at 17:46
  • Is there an alternative package or is this functionality of what ffmpeg offers just not going to be offered on 14.04? – wardr Apr 15 '14 at 17:46
  • Really, I do not know --- I use ffmpeg by command line and nothing more, and the static build works for me. But I suppose that 14.04 will still stay with libav (notice that libav name is used in the two projects, but are different things). In debian the discussion is still on https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=729203 – Rmano Apr 15 '14 at 17:50
