170External library support:
5e220344
AK
171
172 Using any of the following switches will allow Libav to link to the
173 corresponding external library. All the components depending on that library
174 will become enabled, if all their other dependencies are met and they are not
175 explicitly disabled. E.g. --enable-libwavpack will enable linking to
176 libwavpack and allow the libwavpack encoder to be built, unless it is
177 specifically disabled with --disable-encoder=libwavpack.
178
179 Note that only the system libraries are auto-detected. All the other external
180 libraries must be explicitly enabled.
181
182 Also note that the following help text describes the purpose of the libraries
183 themselves, not all their features will necessarily be usable by Libav.
