[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.
