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