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