Is it possible to install ffmpeg and libav together ?

Hello,

I have an application (KeyFinder) that requires libav...

when I install libav I have to un-install ffmpeg..which breaks several other applications...VLC, MPD, etc..

Is there any way to just install libav for KeyFinder so it wont break the other applications?

Any help is very appreciated!
-Thanks

By the looks of it, libav provides the ffmpeg package, so try installing libav first.

Re: Is it possible to install ffmpeg and libav together ?

I have had libav installed and when I try to install ffmpeg it has to be removed..which after a reboot breaks VLC and MPD and a few other apps that depend on ffmpeg.
Either way I go, libav first or ffmpeg first, things are broken..

I am wondering if there is a way to install libav separately just for the KeyFinder application..which will leave ffmpeg alone and keep my other apps from breaking.

You could install it to a separate directory, then start the program in question with LD_LIBRARY_PATH=<path>

Edit: That's assuming it's just using the libraries. If it's using the executables in /usr/bin, this won't work.

Have you simply tried building it with ffmpeg?

I found your earlier AUR post by searching for your error. Bummer! What Scimmia posted may be your only solution other than rebuilding everything else that requires ffmpeg against libav.

Re: Is it possible to install ffmpeg and libav together ?

OKay! Thanks for your help!

How do I install libav to a specific directory?

I am a big yaourt user, so if you can instruct me how to do it using yaourt that would be awesome! but if not I will build it manually and install to a specific directory.

thank you everyone for your time and assistance!!

Re: Is it possible to install ffmpeg and libav together ?

I can compile "keyfinder-git" with ffmpeg 1:2.2-2 and a very small sed-patch in the PKGBUILD:

build() {
  cd $_gitname
  qmake-qt5
  sed -i "s/^DEFINES *=/& -DAVCODEC_MAX_AUDIO_FRAME_SIZE=192000 /" Makefile
  make
}

Edit: For a good fix you should move to the new API with e.g. av_frame_alloc and remove calls to deprecated API functions.

Re: Is it possible to install ffmpeg and libav together ?

awesome progandy! so i add that in ffmpeg's or keyfinders PKGBUILD?

and to your edit, what exactly does that imply i do, or where really might be a better question.

You'll have to excuse me, I am still somewhat of a novice when it come to some of this stuff:P

You modify the keyfinder PKGBUILD.

and to your edit, what exactly does that imply i do, or where really might be a better question.

That implies changing the keyfinder sourcecode and use newer libav/ffmpeg functions which are meant to replace the deprecated stuff. Since this is a larger task, I do not think it is something you can do. (If you don't want to learn writing code).

That sed-patch did not work for me actually. Still get the same error.
