xine-lib is a free multimedia engine, released under the GNU GPL. See COPYING
If you're reading this and you maintain an application which uses xine-lib
1.1, you should be considering moving to xine-lib 1.2. You may need to
adapt your software a bit: various deprecated/obsolete interfaces, present
in 1.1, have gone in 1.2.
The 1.1 series is, as of early 2012, receiving bug fixes only. It is
regarded as deprecated, and is likely to become obsolete and (mostly)
unmaintained in 2013, or possibly a little sooner.
see the doc/ directory for more information about xine-lib. You will find
various README files, FAQ and developer documentation (xine hacker's guide)
there. Developers will find additional documentation for xine interfaces
in the form of header file comments in the xine sources (for example the
xine-lib API is documented in the include/xine.h header file).
Individual frontends (e.g. xine-ui, gxine, totem, ...) may provide
additional documentation in their packages.
