377 kx External library support:
377 kx
377 kx Using any of the following switches will allow FFmpeg to link to the
377 kx corresponding external library. All the components depending on that library
377 kx will become enabled, if all their other dependencies are met and they are not
377 kx explicitly disabled. E.g. --enable-libopus will enable linking to
377 kx libopus and allow the libopus encoder to be built, unless it is
377 kx specifically disabled with --disable-encoder=libopus.
377 kx
377 kx Note that only the system libraries are auto-detected. All the other external
377 kx libraries must be explicitly enabled.
377 kx
377 kx Also note that the following help text describes the purpose of the libraries
377 kx themselves, not all their features will necessarily be usable by FFmpeg.
