Apply the luma key filter to the YCbCr values during the CSC conversion
in video buffer shader. The initial values of max and min luma are set
to opposite values to disable the filter initially and will be set when
enabling it.
Add extra parmeters min and max luma for the luma key filter in
vl_compositor_set_csc_matrix in va, xvmc. Setting them
to opposite value 1.f and 0.f respectively won't effect the CSC
conversion
v2: -Squash 1,2 and 3 into one patch to avoid breaking build of
other components. (Christian)
-use ureg_swizzle. (Christian)
-change name of the variables. (Christian)
v3: -Squash all patches in one to avoid breaking of build. (Emil)
-wrap functions properly. (Emil)
-use 0.0f and 1.0f instead of 0.f and 1.f respectively. (Emil)
v4: -Divide it in two patches one which introduces the functionality
and assigs dummy values to the changed functions and second which
implements the lumakey filter. (Christian)
-use ureg_scalar instead ureg_swizzle. (Christian)

File: docs/README.WIN32 Last updated: 21 June 2013 Quick Start ----- ----- Windows drivers are build with SCons. Makefiles or Visual Studio projects are no longer shipped or supported. Run scons libgl-gdi to build gallium based GDI driver. This will work both with MSVS or Mingw. Windows Drivers ------- ------- At this time, only the gallium GDI driver is known to work. Source code also exists in the tree for other drivers in src/mesa/drivers/windows, but the status of this code is unknown. Recipe ------ Building on windows requires several open-source packages. These are steps that work as of this writing. - install python 2.7 - install scons (latest) - install mingw, flex, and bison - install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs get pywin32-218.4.win-amd64-py2.7.exe - install git - download mesa from git see http://www.mesa3d.org/repository.html - run scons General ------- After building, you can copy the above DLL files to a place in your PATH such as $SystemRoot/SYSTEM32. If you don't like putting things in a system directory, place them in the same directory as the executable(s). Be careful about accidentially overwriting files of the same name in the SYSTEM32 directory. The DLL files are built so that the external entry points use the stdcall calling convention. Static LIB files are not built. The LIB files that are built with are the linker import files associated with the DLL files. The si-glu sources are used to build the GLU libs. This was done mainly to get the better tessellator code. If you have a Windows-related build problem or question, please post to the mesa-dev or mesa-users list.
