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