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.
