Issue with ffmpeg, installation failed

[AC=172]

Hi,

when I try to install the ffmpeg library or any package related to it, such as
gstreamer ffmpeg plug-in
libavcodec53
libavdevice53
vlc

I got the following error
libavcodec53-0.10.2-54.el6.x86_64 requires libvpx.so.1()(64bit)

The fact is that I do have the library VP8 SDK:
$ ll /usr/lib64/libvpx*
lrwxrwxrwx. 1 root root 15 Jul 7 20:45 /usr/lib64/libvpx.so -> libvpx.so.0.0.0
lrwxrwxrwx. 1 root root 15 Jul 7 20:42 /usr/lib64/libvpx.so.0 -> libvpx.so.0.0.0
lrwxrwxrwx. 1 root root 15 Jul 7 20:42 /usr/lib64/libvpx.so.0.0 -> libvpx.so.0.0.0
-rwxr-xr-x. 1 root root 402K Dec 21 2010 /usr/lib64/libvpx.so.0.0.0
lrwxrwxrwx. 1 root root 15 Jul 7 21:12 /usr/lib64/libvpx.so.1 -> libvpx.so.0.0.0

I am running SL6.2, kernel 2.6.32-220.23.1.el6.x86_64

Any suggestion to solve this issue is welcome!

What repo are you trying to install from and what repos do you have active?

This sounds like a repo conflict to me but you need to provide the complete output of the 'yum install' command for us to be able to debug this.

Also did you create the symlink "/usr/lib64/libvpx.so.1" manually?

You appear to have libvpx.so.0 installed, not libvpx.so.1.

What's the output of:
rpm -qa|grep vpx

I didn't find an "attachment option", thus I pasted the outputs here: I hope it's still readble...


yes, I created libvpx.so.1 manually since I haven't found libvpx.so.1 in any repository.



$ rpm -qa|grep vpx
libvpx-utils-0.9.0-8.el6_0.x86_64
libvpx-0.9.0-8.el6_0.x86_64

Ok, you might as well remove that symlink as it's useless, libvpx.0 and libvpx.1 are different (libvpx.1 is in the libvpx-1.0 package, atrpms has it and my linuxtech repo has it).

The thing is you have made the classic mistake that most newbies to SL / Centos / RH do (it's nothing to be ashamed of, we all live and learn! ), i.e. you have enabled loads of conflicting third party repos.
You need to decide between atrpms or rpmforge or epel (elrepo can stay enabled as it generally plays nice with any of them).
(alternatively there is also my linuxtech repo which is specialised in audio/video packages and has quite a few packages that none of the others have so might be interesting to you too, depending on what you are interested in)

My personal opinion about each of these:
atrpms: large choice of packages and generally quite bleeding edge, but packages are of very varying quality
rpmforge: large choice and good quality packages but quite dated versions
epel: large choice and good quality packages, but lack of support for many controversial A/V codecs and packages
linuxtech: (my repo so I'm biased!) smaller choice of packages but focussed on A/V stuff with quite a few interesting packages that no other repo has, packages are mostly recent versions, good quality of packages, very wide support for A/V codecs

Also check what packages you have already installed from any of these three repos before choosing which one you go for as that will necessarily influence your decision.

including info on which ones not to mix.

Many thanks for the advices.

I disabled the conflicting repositories, I left atrpms but
yum search libvpx-1.0
returns nothing.

And, of course, I still cannot install ffmpeg.

Many thanks for the advices. I disabled the conflicting repositories, I left atrpms but yum search libvpx-1.0 returns nothing. And, of course, I still cannot install ffmpeg.

libvpx-1.0 is in atrpms testing. I find http://pkgs.org is a good place to search for available packages but I recommend to always install packages with yum, not by downloading them via pkgs.org.
http://pkgs.org/search/?keyword=libvpx&search_on=name&distro=82&arch=64-bit

P.S: this is a good example of why I consider atrpms packages of 'varying' quality. A package in the main repo should never depend on a package in the testing repo that's disabled by default. (the other way round would be ok)

Great!
It worked!
Thanks!
