172External library support:
5e220344
AK
173
174 Using any of the following switches will allow Libav to link to the
175 corresponding external library. All the components depending on that library
176 will become enabled, if all their other dependencies are met and they are not
177 explicitly disabled. E.g. --enable-libwavpack will enable linking to
178 libwavpack and allow the libwavpack encoder to be built, unless it is
179 specifically disabled with --disable-encoder=libwavpack.
180
181 Note that only the system libraries are auto-detected. All the other external
182 libraries must be explicitly enabled.
183
184 Also note that the following help text describes the purpose of the libraries
185 themselves, not all their features will necessarily be usable by Libav.
