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