External library support: |
|
|
|
Using any of the following switches will allow Libav 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 Libav. |
