Can the developers add this patch into the next release? I tried downloading the Plex 0.83 source and modify the code myself but it wouldn’t build because I don’t know what I’m doing. 
It adds the ability to specify a path to scan for new content instead of scanning the entire media source directories. I would like to use this argument as part of a post-processing script from SABnzbd+ which I’m calling as
/usr/bin/curl -o /dev/null --stderr /dev/null --silent --get 'http://127.0.0.1:3000/xbmcCmds/xbmcHttp?command=ExecBuiltIn¶meter=XBMC.updatelibrary(video,$SAVEDLOCATION)'
Thanks
Here is a modified elan-plex-d6f5f1f/xbmc/Util.cpp from the 0.83 source. Changes start on line 4506 and not 3250 like it is in the diff patch file.
