runmpv needs a directory, where it could put domain sockets on linux. And maybe other temporary things. Right now this directory is taken from XDG_RUNTIME_DIR environment variable and if XDG_RUNTIME_DIR is not defined, then runmpv puts its tmp files to /tmp .
Windows doesn't use tmp directory, but that might change in future
User should be able to specify this directory either in runmpv.properties or through command line switches.
