upnp_play – Play a file on a mediaplayer

This is a very simple a straight forward UPNP play function. It searches a file on a mediaserver and plays it on the mediaplayer. It does not include search of mediaplayer/server URLs as the UPNP discovery take some time. Use the script below to find the correct urls.
