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.
