187External library support:
5e220344
AK
188
189 Using any of the following switches will allow Libav to link to the
190 corresponding external library. All the components depending on that library
191 will become enabled, if all their other dependencies are met and they are not
192 explicitly disabled. E.g. --enable-libwavpack will enable linking to
193 libwavpack and allow the libwavpack encoder to be built, unless it is
194 specifically disabled with --disable-encoder=libwavpack.
195
196 Note that only the system libraries are auto-detected. All the other external
197 libraries must be explicitly enabled.
198
199 Also note that the following help text describes the purpose of the libraries
200 themselves, not all their features will necessarily be usable by Libav.
