174 External library support:
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.
183 Note that only the system libraries are auto-detected. All the other external
184 libraries must be explicitly enabled.
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.

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

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
