+2006, 2007, 2008 Free Software Foundation, Inc.
+
+ This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+ Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+ 6. Often, you can also type `make uninstall' to remove the installed
+ files again.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+ On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor. Like
+this:
+
+ ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CPP="gcc -E" CXXCPP="g++ -E"
+
+ This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+ By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Particular systems
+==================
+
+ On HP-UX, the default C compiler is not ANSI C compatible. If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+ ./configure CC="cc -Ae"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+ On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file. The option `-nodtk' can be used as
+a workaround. If GNU CC is not installed, it is therefore recommended
+to try
+
+ ./configure CC="cc"
+
+and if that doesn't work, try
+
+ ./configure CC="cc -nodtk"
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on. Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+ Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug. Until the bug is fixed you can use this workaround:
+
+ CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+ Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+ Print a summary of the options unique to this package's
+ `configure', and exit. The `short' variant lists options used
+ only in the top level, while the `recursive' variant lists options
+ also present in any nested packages.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+ Use DIR as the installation prefix. *Note Installation Names::
+ for more details, including other options available for fine-tuning
+ the installation locations.
+
+`--no-create'
+`-n'
+ Run the configure checks, but stop before creating any output
+ files.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+
+ OVERVIEW
+
+/********************************************************************/
+
+ XvMC extends the X-Video extension (Xv) and makes use of the
+ familar concept of the XvPort. Ports have attributes that can be set
+ and queried through Xv. In XvMC ports can also have hardware motion
+ compensation contexts created for use with them. Ports which support
+ XvImages (ie. they have an "XV_IMAGE" port encoding as described in
+ the Xv version 2.2 API addendum) can be queried for the list of XvMCSurface
+ types they support. If they support any XvMCSurface types an
+ XvMCContext can be created for that port.
+
+ An XvMCContext describes the state of the motion compensation
+ pipeline. An individual XvMCContext can be created for use with
+ a single port, surface type, motion compensation type, width and
+ height combination. For example, a context might be created for a
+ particular port that does MPEG-2 motion compensation on 720 x 480
+ 4:2:0 surfaces. Once the context is created, referencing it implies
+ the port, surface type, size and the motion compensation type. Contexts
+ may be "direct" or "indirect". For indirect contexts the X server
+ renders all video using the data passed to it by the client. For
+ direct contexts the client libraries render the video with little
+ or no interaction with the X server.
+
+ XvMCSurfaces are buffers into which the motion compensation
+ hardware can render. The data in the buffers themselves are not client
+ accessible and may be stored in a hardware-specific format. Any
+ number of buffers can be created for use with a particular context
+ (resources permitting).
+
+ XvMC provides video acceleration starting at one of two places
+ in the video pipeline. Acceleration starting at the first point,
+ which we shall call the "Motion Compensation" level, begins after the
+ the inverse quantization and IDCT at the place where motion compensation
+ is to be applied. The second point, which we shall call the "IDCT"
+ level, begins before the IDCT just after the inverse quantization.
+
+ Rendering is done by presenting the library with a target XvMCSurface
+ and up to two reference XvMCSurfaces for the motion compensation, a
+ buffer of 8x8 blocks and a command buffer which describes how to
+ use the 8x8 blocks along with motion compensation vectors to construct
+ the data in the target XvMCSurface. When the pipeline starts at the
+ IDCT level, Xv will perform the IDCT on the blocks before performing
+ the motion compensation. A function is provided to copy/overlay a
+ portion of the XvMCSurface to a drawable with arbitrary scaling.
+
+ XvMCSubpictures are separate surfaces that may be blended with the
+ target surface. Any number of XvMCSubpictures may be created for use
+ with a context (resources permitting). Both "backend" and "frontend"
+ subpicture behavior are supported.

+)
+
+ The behavior of these two functions is different depending on whether
+or not the XVMC_BACKEND_SUBPICTURE flag is set in the XvMCSurfaceInfo.
+
+ XVMC_BACKEND_SUBPICTURE set:
+
+ XvMCBlendSubpicture associates the subpicture with the target_surface.
+ Both will be displayed at the next call to XvMCPutSurface. Additional
+ blends before the call to XvMCPutSurface simply overrides the association.
+ Both the target_surface and subpicture will query XVMC_DISPLAYING from
+ the call to XvMCPutSurface until they are no longer displaying. It is
+ safe to associate the subpicture and target_surface before rendering has
+ completed (while they still query XVMC_RENDERING) but it is not safe to
+ call XvMCPutSurface at that time.
+
+ XvMCBlendSubpicture2 copies the source_surface to the target_surface
+ and associates the subpicture with the target_surface. This essentially
+ calls XvMCBlendSubpicture on the target_surface after the copy. Both
+ the subpicture and target_surface will query XVMC_DISPLAYING from the
+ call to XvMCPutSurface until they are no longer displaying. The
+ source_surface will not query XVMC_DISPLAYING as a result of this function.
+ The copy is pipelined with the rendering and will cause XVMC_RENDERING
+ to be queried until the copy is done.
+
+
+ XVMC_BACKEND_SUBPICTURE not set ("frontend" behavior):
+
+ XvMCBlendSubpicture is a no-op in this case.
+
+ XvMCBlendSubpicture2 blends the source_surface and subpicture and
+ puts it in the target_surface. This does not effect the status of
+ the source surface but will cause the target_surface to query
+ XVMC_RENDERING until the blend is completed.
+
+
+ display - The connection to the server.
+
+ subpicture - The subpicture to be blended into the video.
+
+ target_surface - The surface to be displayed with the blended subpicture.
+
+ source_surface - Source surface prior to blending.
+
+ subx -
+ suby -
+ subw -
+ subh - The rectangle from the subpicture to be blended.
+
+ surfx -
+ surfy -
+ surfw -
+ surfh - The rectangle in the XvMCSurface to blend the subpicture rectangle
+ into. If XVMC_SUBPICTURE_INDEPENDENT_SCALING is not set in the
+ XvMCSurfaceInfo subw must be equal to surfw and subh must be
+ equal to surfh height or else a BadValue error occurs.
+
+ Errors:
+
+ XvMCBadSurface - Any of the surfaces are invalid.
+
+ XvMCBadSubpicture - The subpicture is invalid.
+
+ BadMatch - The subpicture or any of the surfaces do not belong to the
+ same context.
+
+ BadValue - XVMC_SUBPICTURE_INDEPENDENT_SCALING is set and the source
+ and destination rectangles are different sizes.
