sshambar c54c909ae4 Added support for libav/ffmpeg dual installs (#346) ... * [config] Added support for libav/ffmpeg dual installs Reordered CPPFLAGS/LIBS so that library flags (includes etc) appear ahead of prefix/global directives and the correct headers/libraries are checked (if symbols are defined in alternative libraries). Updated libav checks to use header declaration checks rather than link checks (so differences between libav/ffmpeg can be correctly found), and updated code references to use new defines. Added support the alternate pkg-config package names for libav. Updated ffmpeg vs libav check to check MICRO version number (>=100 for ffmpeg). Simplified resulting configure script by using a function to merge CPPFLAGS variables. * [config] Use FORKED_OPTS prefix for libevent_pthreads option * [config] Add --with-libav option to select libav even if ffmpeg present		2017-02-19 15:21:00 +01:00
