172 External library support:
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.
181 Note that only the system libraries are auto-detected. All the other external
182 libraries must be explicitly enabled.
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.

384 If you think configure made a mistake, make sure you are using the latest
385 version from Git. If the latest version fails, report the problem to the
386 libav-tools@libav.org mailing list or IRC #libav on irc.freenode.net.
388 if disabled logging; then
390 Rerun configure with logging enabled (do not use --disable-logging), and
391 include the log this produces with your report.
395 Include the log file "$logfile" produced by configure as this will help
