Those are the libraries for ffmpeg and they are not part of the default repositories.  The NUX Desktop repo has them: https://li.nux.ro/repos.html

The packages you want from that repo are “ffmpeg” and “ffmpeg-devel”

Subject: [SR-Users] Installing RTPengine on CentOS 7

Hi,

I'm trying to install RTPengine in the same machine as I have Kamailio, running CentOS 7, but there are a few dependencies that yum cannot seem to resolve and I that cannot find anywhere else.

As soon as I try to build the daemon it produces these errors:

make[1]: Leaving directory `/usr/local/src/rtpengine/daemon'

Failed build with ../lib/fix_frame_channel_layout-01.h

Trying build with ../lib/fix_frame_channel_layout-02.h

make[1]: Entering directory `/usr/local/src/rtpengine/daemon'

rm -f "resample.c"

echo '/******** GENERATED FILE ********/' > "resample.c"

cat ../lib/"resample.c" >> "resample.c"

Package libevent_pthreads was not found in the pkg-config search path.

Perhaps you should add the directory containing `libevent_pthreads.pc'

to the PKG_CONFIG_PATH environment variable

No package 'libevent_pthreads' found

Package libavcodec was not found in the pkg-config search path.

Perhaps you should add the directory containing `libavcodec.pc'

to the PKG_CONFIG_PATH environment variable

No package 'libavcodec' found

Package libavformat was not found in the pkg-config search path.

Perhaps you should add the directory containing `libavformat.pc'

to the PKG_CONFIG_PATH environment variable

No package 'libavformat' found

Package libavutil was not found in the pkg-config search path.

Perhaps you should add the directory containing `libavutil.pc'

to the PKG_CONFIG_PATH environment variable

No package 'libavutil' found

Package libswresample was not found in the pkg-config search path.

Perhaps you should add the directory containing `libswresample.pc'

to the PKG_CONFIG_PATH environment variable

No package 'libswresample' found

Package libavfilter was not found in the pkg-config search path.

Perhaps you should add the directory containing `libavfilter.pc'

to the PKG_CONFIG_PATH environment variable

No package 'libavfilter' found

So, in the end, at least 'libevent_pthreads','libavcodec', 'libavformat', 'libavutil', 'libswresample' and 'libavfilter' are missing.

Trying to install them one by one with yum fails because it cannot find these packages for CentOs 7.

Can anyone point me to a solution for this?

Thanks,

Francisco.
