Ring-daemon compile fails on resampler.cpp
Source that failed is ring-daemon/src/media/audio/resampler.cpp. Error is no file <libswresample/swresample.h> In fact the file does exist but the path ( /usr/include/ffmpeg ) was not included in the CXXFLAGS. I am ignorant of cmake so I worked around the problem in ring-daemon/src/media/audio/Makefile. In line am__append_8 I added -I/usr/include/ffmpeg. Compiled successfully.
