    44This [/wiki/CSC CSC] module takes advantage of nvidia GPU's [http://www.nvidia.com/object/cuda_home_new.html CUDA] capability to parallelize the conversion process and speed things up.
    5 You may also consider using the [/wiki/CSC/OpenCL OpenCL CSC] module, which can also use the GPU and is more generic (not vendor specific).

    1010* you need to build xpra with the flag "{{{--with-csc_nvcuda}}}", since this module is not enabled by default.
    1111* you must use a sufficiently recent version of the {{{nvidia}}} video drivers, preferably obtained directly from nvidia, and not the {{{nouveau}}} drivers (which you should probably remove).
    12 * the build file relies on the presence of a standard pkgconfig file to find the CUDA libraries and headers. nvidia does not provide one with the SDK, so you will need to create one. You can use this example [/attachment/wiki/CSC/NVCUDA/cuda.pc cuda.pc] as a template.
